Prop 8’ers, We Still Gotta Talk
Interesting letter in yesterday’s Tribune by Alexis Murrel of Los Osos (Yes! Another Bearish Folk):
“Henry Giacomantonio says in his Nov 29[Tribune] letter that ‘marriage is and always has been a religious institution.’ While this statement is certainly debatable, let’s just assume for the time being that he’s right. In that case ‘married’ couples should receive no legal recognition. If it’s solely a religious institution, then it shouldn’t involve legal privileges regarding finances, parenting, immigration or inheritance. And there certainly shouldn’t be any tax breaks.
“If it’s a religious institution, the Constitution mandates that it cannot have anything to do with the government.
“You can keep your word ‘marriage’ – if you give back all of the civil benefits you’ve been taking advantage of for centuries. You can’t have your wedding cake and eat it too.”
Heh-heh. Nice ending. That Alexis is right can be seen in the words the preacher speaks at the end of the wedding ceremony (at least the minister did at my wedding): “By the power vested in me by the State of California, I now pronounce you . . . .” and etc. Seems clear that what we’re looking at here is a STATE, CIVIL ceremony. And no church or synagogue can “marry” anybody legally without that state piece of paper – the “marriage” license. And as such, the state (civil, secular) needs to ‘splain how denying certain groups of citizens the same rights as others is warranted.
Also still in the mix, an AP piece by Jesse Washington called, “Is Gay the New Black.” “Gay is the new black, say the protest signs and magazine covers, casting the gay marriage battle as the last frontier of equal rights for all.
“Gay marriage is not a civil right, opponents counter, insisting that minority status comes from who you are rather than what you do.”
Ah, now that’s a discussion worth having. What you are versus what you do. When you put aside Biblical teaching, I suspect what’s at the heart of the fear and dislike many straight people really feel towards gay people involves what gay people do with their naughty parts. Gone missing, of course, is that straight people do exactly the same things with their naughty parts too. So, what’s the difference? I mean, C’mon, there’s only so much one can possibly do with the set of naughty parts each sex is given, no matter how creative you are or how combine the possibilities, even if you toss in gourmet vegetables, a loofa AND Bill O’Reilly!
So declaring someone is a second class citizen based on what he or she does with his or her naughty parts doesn’t make much sense since straight people are busy doing the same things with their naughty parts. (And whatever do we do about bisexuals? They can get married even though they're "doing" same sex naughty stuff, just like gay people? That's somehow OK? If so, then there goes the "doing/being" notion.)
So, what are we basing this second class citizenship on? Can’t be “the children” since gay people have both natural children and adopted children, just like straight people. It can’t be “religious” because the “marriage” laws are secular and civil. Heck, even the “license” comes from the state. Without it, a church is powerless to “marry” anyone and have it mean anything. (Churches can’t “divorce” anyone either. That’s also a civil matter.) And it can’t be what straight people do with their naughty parts because there’s nothing in the law that says, you can get married ONLY if you engage in “proper” male/female procreative sex in the missionary position during fertile times of the month; all other sexual practices will result in the Divorce Police breaking into your bedroom and dragging you to Divorce Court.
So if straights and gays are all DOING the same sorts of things or variants thereof, then are we basing this second class citizenship on . . . BEING? And since “being” isn’t a “choice,” then that does open up a can of worms, now doesn’t it? Are we now to have second class citizenship for a certain group of people because of WHAT they are, not what they do? And if Prop 8 has set up a new class, then doesn’t the State have a responsibility to ‘splain the compelling interest to the state in maintaining this second class status?
Otherwise, we have taken a huge step backward, since the whole thrust of our Constitution – in its groping search for a more perfect union – has been to guarantee equal treatment under law of all citizens.
Note To Young Students Away From Home For The First Time and Partying Hearty
Alcohol ingested in large quantities over a short period of time can poison you and you can die. It’s clear that this fact is an amazingly well kept secret since every year we get news reports of alcohol poisoning deaths on campus, just as regular as clockwork. Apparently, many young students appear to be impervious to this well-known fact. I’m beginning to suspect it’s some sort of Darwinian mechanism at work. Getting out of childhood and young adulthood alive and in one piece is looking more and more like a lethal Tontine – smarts and luck ensure a certain percent of the most hardy and clever make it through. Mother Nature is never pretty. Neither is a parent’s grief over the death of a child. That is beyond measure.

………………….A quick note about killing unborn children would be nice, too.
If my Aunt had testicles, she would have been my Uncle.
When the civil right to life is restored to the unborn the gays and lesbians who wish to have a civil union may have a better chance at getting a law that supports it.
W-Mark; A certain percentage of the unborn Pre-Old People will be determined, by processes that begin in the womb, to be Gay.

Our Justice system also protects (to some degree) non-citizens. Justice Brenner said, to the best of my recollection, that the purpose of the justice system is to protect the Minority FROM the Majority.
The voters that the politicians are interested in capturing, are 18 years of age. Some of those are currently in Iraq, a location that Osama Bin Ladin would never had taken refuge in, prior to our Regime change. But, they are "Cannon Fodder", not really someones "Children".
IUD or IED Take your pick, by the pen or by the sword.
I'm a little confused by the first sentence in the Last paragraph. Is this your Aunt by Marriage or by blood. What if your Aunt wanted to marry her female life partner? Would you refer to them as my two Aunts? I think it would work better if you used your Grandmother in your example.
And would that make you your own Grandpa?

Subject: SNL Skit
This would be mind-bendingly hilarious… if it weren’t so damned accurate… see it before it disappears.
THE FORBIDDEN SNL ‘BAILOUT’ SKIT
Apparently, Saturday Night Live did a "Bailout" skit, which has created some incredible problems for NBC.
I've heard that They have pulled the video, and apparently gone after anyone who put the video out there, because the video has all but disappeared off the Internet.
It was up on multiple sites and virtually all the copies are gone now. There are a few new "edited" copies on the net.
Now, how much power would you have to have, to pull something from the entire Internet?
Here is one copy still on the Internet:
http://msunderestimated.com/SNLBailoutSkit.wmv
Mark,
If that skit had been causing such problems as you suggest, why did they re-run it last Saturday night? Why would NBC have the skit on their own website? http://www.nbc.com/Saturday_Night_Live/video/clips/c-span-bailout/727521/
Sounds as if you are passing on a myth as if it were a fact.
The simple explanation is this ... NBC owns the content and NBC wants to put the content on their own website so they send letters to youtube (etc.) on a regular basis when they discover material they own appears without permission. Viacom does the same thing with Daily Show clips.
Mark, it's not too hard to track down these myths before passing them on as if they are fact.
Because you seen to have some time on your hands, winter break coming up and all:
ECOfluid USBF MBR Bioreactor for $7.4 a gallon that produces tertiary Title 22 water together with directional drilled and installed collection systems, are a fraction of any contrivance currently considered.
Why is that?
Mark,
Let us know once the RWQCB has signed off on your device for use in Los Osos in place of a sewer.
Once again for those over at Cal Poly.
The WB will not examine/consider anything that isn't put forward by a responsible entity, in this case, at this time is SLOCO aka Paavo as he alone will decide what will be entitled to float to the surface.
The SLOCO BOS are elected/"hired" by the people. The sups hired Paavo.
I certainly do expect that the fiduciary duty incumbent upon everyone will be executed.
They all work for the people and can be held accountable before, during and certainly after any "act(s)".
I'll repeat this statement and important question:
ECOfluid USBF MBR Bioreactor for $7.4 a gallon that produces tertiary Title 22 water together with directional drilled and installed collection systems, are a fraction of any contrivance currently considered.
Why is that?
Okay Mark,
Explain then, if your system is sooooooo much better, did you send the technical details to the County when they requested conceptual bids from all comers?
Frankly, if you wait until after the EIR is finished to complain that they didn't consider your system which you are only now letting them know about, it is more of the exact same sort of thing which has caused Los Osos so much difficulty in the past. People with "really good ideas" coming forward to derail the process because they didn't follow it properly early on.
HI Shark... Since Mark blogs so much, he doesn't appear to have time to do technical (only timestaking readings on quotable quotes) research and certainly doesn't have time to make technical submittals or meetings with agencies for approval of his shotgun-type marketing approach...
Maybe our County have read (and re-read) his multitude of overdone blog entries and are left wondering whether he actually has some product that might be the Los Osos sewer solution...??? Maybe he was too busy "impressing" us and so missed working directly with those who have acceptance responsibilities...or maybe they rejected his product and he is appealing to this blog, thinking we had any decision making authority...??? Either way, he continues to beat that dead horse... Perhaps we should contact ECOfluid directly to see what light they may shed on any RWQCB or SLO County approvals of their products...

Please provide the link that backs up your statement that the:

Your statements regarding my submission of ECOfluid demonstrates you are not reading carefully.

It matters only that ECOfluid was reviewed or not.
If it was where is the report?
If is wasn't, why not?

Wow. Must be a darn good company. Maybe the best if Mark Low represents it.

Murphy’s former partner, Mark Low, got fed up and left. After his departure in late May, Low started sending a string of e-mails to environmental bureaucrats, politicians, and reporters that poke holes in the Reclamator’s effectiveness, and Murphy’s business model.
and finally this?
“They’re like sorry losers,” he (Murphy) says of the public agencies that criticize him. “They’re like Mark Low.”
Shazam.
Markus, next time you're scrounging around Wikipedia looking for some quotes to regale us with, look up the word "credibility" and get back to us. And for good measure, throw in a "more tea? and "I love LO" for us. It makes us smile.
Another great Dylan tune for ya: "Idiot Wind." Check it out.
Why not man up MIKE and get yourself a copy of the $7.4/gal proposal.
Ask Steve or Lynette. Or Man up and git yurself an anonymous email account and write me for a copy.
Mark@NOwastewater.com
Or not...
Okay Mark ...
What date was the proposal submitted to the County? Was it complete? Did it contain proof that this system would reduce nitrates to the target level for at least 10 years as the RWQCB has required of other proposed systems?
We're patiently awaiting for answers that demonstrate that the County really dropped the ball. It seems far more likely to me that the information provided to the County was insufficient to justify the selection of your favorite device (this year).
Willy,
Too bad everything I write is true.
I'm glad the record is there to be havested and that you took time to bring it forward.
Mt thanks to Mother Calhoun.
Of course the credibilty of an anonymouse is something only other anonymice would consider as valuable.
The RECLAMATOR was an on lot sans collection pipe solution.
ECOfluid is a patented pre engineered technology that fits at the end of a collection system.
Don't be an idiot, for unless and until you grasp the difference between these technologies you confusion will continue.
Your not paying attention, "it" is still about "your" money and water lost where leaky gravity sewerage is concerned, not mine...
Thanks for the stroll down memory lane, it was fun.
Steve,
Your questions have already been answered by me on previous posts.
I sent you a copy of the most recent proposal submitted to the county.
When asked to do so, you again cannot provide the basis of your statement:...did you send the technical details to the County when they requested conceptual bids from all comers?
I guess you are accustomed to making it up as you go along.
Maybe you or Willy can dig them up. It should take you that long as you stated earlier.
Perhaps the questions you are asking might be best answered by the county/Paavo?Mark Huthinson?John Waddel? as it will be those answers which will actually matter when the time comes.
Of course, I have proof of submission going back to May of 2007. As far as the ten years of data, no problem.
My question still stands as unanswered by anyone, including you, who will order or pay for the LOSTDEP solution. Interesting isn’t it…
ECOfluid USBF MBR Bioreactor for $7.4 a gallon that produces tertiary Title 22 water together with directional drilled and installed collection systems, are a fraction of any contrivance currently considered.
Why is that?
Steve,
You asked:
What date was the proposal submitted to the County? Was it complete? Did it contain proof that this system would reduce nitrates to the target level for at least 10 years as the RWQCB has required of other proposed systems?
I am interested where this information is for the "choices" made by the county.
Can you share the location of that information with me?
You are asking for something from me which has not been asked for or supplied from anything I have read.
Your prompt respose will help to clarif my pioint(s).
Thanks again Ann, your blog is serving the public well!

Mark,
I have to admit that I didn't read all 8 megabytes and how many hundreds of pages of information you send.
Perhaps you could help me out by telling me which document submitted to the County contained the evidence that there is a 10 year history of nitrate removal. Better yet, page number.
As for MBR's proof ... the many plants which have been operational for more than 10 years show that nitrate removal can be achieved by MBR. Duh!
Thanks a bunch!
Steve,
If you don't do your homework how can you expect to do well "on the field"?
Please show me where the county has shown- "the evidence that there is a 10 year history of nitrate removal. Better yet, page number."
Are you getting it yet? DOH!
Fouling and fouling control
The MBR filtration performance inevitably decreases with filtration time. This is due to the deposition of soluble and particulate materials onto and into the membrane, attributed to the interactions between activated sludge components and the membrane. This major drawback and process limitation has been under investigation since the early MBRs, and remains one of the most challenging issues facing further MBR development [4], [5].
http://en.wikipedia.org/wiki/Membrane_bioreactor
The big news regarding ECOfluid’s USBF process combined with a Membrane is that because effluent from the bioreactor feeds into and through the membrane by gravity alone.
Thus the “fouling” problems associated with all other designs are overcome. This saves energy and produces a more efficient, reliable and effective tertiary water.
Gee, I think that Paavo and his team sould be most interested in this information. Who wouldn’t and why?
Mark,
If you even know the details of the materials you sent me, you should be able to point out where your (current) system has a proven track record.
If you don't provide this reference, I can reasonably conclude that your system doesn't have the sort of proof I want to see or that you are simply being pig-headed for no particular reason. It is not incumbent on me to do your research for you. If you want to convince me and others ... do it. If you don't want to convince people here, stop wasting your time.
On the matter of 10 years of nitrate removal history. The RWQCB in the past has asked for this from the LOCSD for one of their proposed systems. Because the ponding system proposed didn't have this history, they said that it was a non starter.
And, on the matter of the County proposed treatment technologies, you are asking me to provide proof of standard systems with known characteristics ... you seem confused. It is not me who needs to prove anything to you, but you who needs to prove something to the County and to me.
If the treated wastewater is going to be disposed of inside Los Osos, it is required to have nitrates below a certain level. Does your system output treated water? Where will it go? If it will go into the ground, it needs to have no nitrates in it.
Are you getting it yet? DOH!
Watershed Mark said...
So nothing in writing that you can point to regarding activated sludge and nitrate reduction from the WB...good enough, I thought a much.
Of course the case studies I sent to the County and Carollo before May 2007 demonstrate nitrogen removal.
There are hundreds of installations of ECOfluid worldwide, several hundred in the United States.
ECOfluid's USBF is a very clever patented variation of Activated Sludge, if you'd like I'll send you the PowerPoint with Engineer’s comments that the County and Carollo received prior to May 2007 which details the process.
Steve, how can anyone prove anything to you, if you cannot or will not read the material presented?
If you don’t understand the basic process of activated sludge and nitrification/denitrification and will not or cannot take the time to learn enough about such matters then you will remain confused.
You see the biology used in nearly every treatment system is the same. The design of the system is what makes them different.
ECOfluid USBF is a very robust and stable single basin plug flow process that paves the way for low cost Title 22 Tertiary water. So you see it too is a “standard system with known characteristics".
The County seems content to build a secondary treatment standard quality water facility for $25M which “can be” upgraded to tertiary. Why?
When an ECOfluid USBF MBR Title 22 Tertiary Facility can be built for $8.8M and as stated in the proposal that figure contains a 30% engineering and contingency component.
So you see Steve, my mission, which I have decided to accept, is to challenge the County Agents and their Agents to explain and report their review and findings regarding ECOfluid USBF MBR.
(If they did not review ECOfluid why not?)
I trust that will happen sooner rather than later. Why wasn’t MBR put in to “their” process as recommended by NWRI and DR T.?
As Paavo Ogren stated on August 14, 2007 …
No nitrates Steve???
I think one of us is confused. DOH!
Gee… tertiary treatment? Oh wait! We already almost had a plant with tertiary treatment - Tri-W!!
We still have drawn-up plans, it was permitted by everyone, Los Osos owns the land, the water never leaves town - some will go to Broderson and the rest would be ready for the purveyors to plan for injection wells!! Sound like this would be cheaper still!
Why is ws mark trying to sell us on tertiary on this blog? Plenty of us here still think we should go with what we had - tertiary. Sounds like it is the County that he needs to sell. As Mark H. said at the last TAC meeting, the County WILL look at other technologies - if they are presented as a bid. Why isn't ws mark tracking down contractors to bid on this - that is what I'd like to know. We are just bloggers. The power is at the County level.
Lymette,
Gee, you might want to focus on the future.
Dwelling in the past will not conserve your money or your water.
Injection well water is tricky business, but you are the expert.
I'm not trying to "sell" anything on this blog. I'm trying to educate you to the pitfalls of the process.
Too bad Mark H didn't include the ECOfluid USBF in the process earlier.
I submitted the ECOfluid information when he called for it prior to the:December 18, 2007: Environmental Impact Report Scoping Meeting at the South Bay Community Center in Los Osos at 7:00 pm. View presentationand Notice of Preparation.
Interesting, isn't it...
Once again, for those of you over at Cal Poly and on 16th street:
Why wasn’t MBR put in to “their” process as recommended by NWRI and DR T.?
I'm not trying to sell you anything Lynette, I am asking a very important question.
It is interesting that Lynette wrote: Plenty of us here still think we should go with what we had - tertiary.
Why would you want an energy intensive process that cost $50/gal when an energy efficient (less electricity usage than ponds) that cost $7.4/gal is available?
Lynette,
When you answer the question above you will illuminate a very dark place.
"Answer Honestly"...
Sewertoons,
The only reason the mid-town site (AKA TriW) was thrown out was the contention in the community. Too bad. You're right about the water reuse issues with TriW and Broderson, but the "stop the sewer/move the sewer/sewer over my dead body" people made such a stink that no county agency wants to deal with it. BTW: mark is an "entrepreneur"which prety much means "I want to make a BUNCH of money without actually working".How is that working for you? By the way , he would be VERY surprised to know how much all of us know about sewer issues.
Mark,
It seems that you, yet again, have neglected to tell us where, in the electronic tome you e-mailed me, one could find the answer to the question you've been asked.
If you cannot tell us where your documentation tells us that there is a proven track record of nitrate removal it would appear that your documents don't have that proof.
Page number? Name of file? Simple questions for the person who has the truth.
As to your suggestion that I should read the ton of material you sent without so much as a hint as to where the answer lies ... you assume that you have the right to waste my time.
Suppose that your job were to convince me that Prop 8 were a good idea (he writes, coming full circle). If I asked you a particular question about whether Prop 8 has any implication on whether homosexual couples should be allowed to adopt or not ... saying "just read the Bible" doesn't really answer the question. If you claim that it does but are unwilling or unable to clearly explain how and where the Bible is applicable to your your point of view, you are not really addressing the question at all but instead avoiding it.
So, Mark, can you tell me where, in the dozen documents you e-mailed me, it shows there is proof of a long-run nitrate removal of your (new) device?
And now, because I refused to waste my time and the time of those who read here, I will bow out, having vainly tried to get you to show us your cards which you claim are a royal flush (haha). If you really have something, prove it! If you don't, we'll know to ignore you like the real poker players ignore the six year old who thinks he is playing in the same game.
Mark sez:"ECOfluid USBF MBR Bioreactor for $7.4 a gallon that produces tertiary Title 22 water together with directional drilled and installed collection systems, are a fraction of any contrivance currently considered
ECOfluid is a patented pre engineered technology that fits at the end of a collection system."
and also sez:"
"The RECLAMATOR was an on lot sans collection pipe solution."
Help! It appears that the RECLAMATOR is a no-no because it was an on-lot system, no collection of anything, disposal on-site, not allowed, also doesn't recharge and so help low lyng areas and doesn't help salt water intrusion. But Mark's new system sounds line an intank system that produces title 22 water that's collected and taken somewhere? Then what? To spray fields? Ag reuse? Purple pipe back into town? Since the collection system is the biggest expense, how is much of anything saved here? Would still need land for spray fields, or the expense of purple pipe back into town? What? Sorry, but I'm missing something here. Perhaps Mark,you can give a simple explanaton as to exactly how your system works. Simple so even I can understand it? Thanks.
Steve wrote: Page number? Name of file? Simple questions for the person who has the truth.
It seems you do not understand the basic wastewater biology of activated sludge.
As you correctly opined, it is a: "standard systems with known characteristics".
Successful "management of the biology" is the key to treatment results for any system,.
ECOfluid USBF designs employ this "biology", in a very clever and patented manner.
When you can provide the information that you are requesting from me from the County's/Carollo's "reports/study" -Page number(?), Name of file(?), Simple questions for the person(s) who are being paid who have the truth, we can continue our discussion.
Please don't think I'm trying to be held to a different standard than County /Carollo. All things should be equal, don't you think...
-Lynette, I'm still waiting to see all the treatment results data and leakage reports from the gtravity and ox-ditch "technology", that the ounty is leaning towards.
Why hasn't it been "reported"?
There are far better technologies than gravity and ox-ditch and they just so happen to cost less.
Choosing one over another could be (thanks Ron "The Man" Crawford) "Technologically Embarrassing".
Mark,
You seem to be fussing now that I'm not pestering the County to provide the same information I am asking you to provide.
First off, I note with interest that you have yet again not answered my question.
Second, in this discussion, the one between you and me, you have suggested there is something underhanded going on at the County. I replied by saying that perhaps your proposed system doesn't meet the County requirements or perhaps you didn't submit documentation that demonstrates this. It would appear that whatever made it into the EIR would meet County requirements. That being said, no, I am not holding you to higher standard than the County. I am asking you where the documentation you submitted to the County would clearly demonstrate that your device meets the needs of our town ... in one particular way. If the disposal of the treated water will be above our aquifer, there needs to be denitrification.
If you can't show us where in the documents you submitted to the County that your proposed solution has a long-run track record of denitrification, we know why they didn't pick your method ... they didn't pick it because you didn't provide appropriate documentation.
So ... if you are gonna continue your argument that something underhanded happened at the County, you should make sure that you provide this simple proof that so far you seem very reluctant to provide.
Waterspout Mark ought to show at least some embarassment in not being able to answer Ann's questions... "...Perhaps Mark,you can give a simple explanaton as to exactly how your system works. Simple so even I can understand it?..."
...and now his non responsive sort of reply to Shark certainly shows a major disconnect with this community and the posters of this blog...
He appears to continue to try "marketing" his complaints to us, when he should be in front of the BOS if he really has a product... It does seem that he was dumped from any realistic consideration bcause and if he actually submitted his proposal to the County in accourdance with their request... Maybe he doesn't recognize that the rules of the game are not his to dictate...
Been up at a lovely brunch at a house on the beach in Cayucos. Warm, gorgeous weather and charming company and way too much delicious food and drink. Yes, I was asked how the sewer project was going.
Now back to this reality.
ws mark, I am puzzled and frankly disappointed at your response to Ann. Your gracious hostess, Ann. The Ann who has been MORE than tolerant of your ramblings. The Ann whose sharp intelligence I admire even if I completely disagree with her sewer and PZLDF positions. The Ann who asked you a simple question. THAT Ann.
You come back with this lame-ass answer that basically tells her nothing and you address a bunch of questions to us. You mark, have dissed your hostess. Your non-response is the kind of non-response that you would give to me, not her. I think you not only owe her the explanation that you were asked for as well as an APOLOGY. Mike has it right - you are majorly disconnected to us.
ws mark asks, "-Lynette, I'm still waiting to see all the treatment results data and leakage reports from the gtravity and ox-ditch "technology", that the ounty is leaning towards."
mark, do your own homework and read the draft EIR.
Nice typos. Try draft writing in a program that points out your errors and then paste them in here. You will look like you put some care into your answers.
Well, dang. I'm still waiting for a simple explanation (no need to divulge proprietary info) as to how Mark's ecofluid thingee works. It appears, from the brief hints, that produces title 22 water, (like the Reclamator promised) BUT I gather that this thingee hooks up to a collection system (under pressure? like a STEP system?)? If so, then where is that Title 22 water supposed to go for reuse or disposal & etc. And since it is collected and if the collection pipe is the biggest expense in any project, where is the savings? True you wouldn't need to build a big sewer plant (use the little mini-plant in side the septic tank, so to speak) but you'd need some disposal plan or the added cost of purple pipe all over town? Something? What? Just a simple explanation will do. THank you.
Hello Ann;
Sorry for the delay, I have been taking a little time off.
I’m working on a “simple” response and will post it no wastewater blogspot when it’s ready.
Meanwhile have a look at ECOfluid (USBF) (results on page xix) here : http://www.waterboards.ca.gov/water_issues/programs/septic_tanks/techonsite/index_introduction.pdf
Check out how much better USBF is to the BESTEP 10 (Forerunner to the RECLAMATOR). There was no disinfection associated with the USBF system tested. That was a single family unit that is shown in the report. The design scales mathematically up to any size flow. It more science and less “study”. That’s why I want to see it openly evaluated against ox-ditch.
USBF was the highest rated four out of five A’s over every other system including Zenon and Kubota.
The BOD AND Nitrogen reduction were second to none. That is important.
The full report here : http://www.waterboards.ca.gov/water_issues/programs/septic_tanks/technosite.shtml
Steve, Please take a hard look at this report, the 1.31 MB. How come there isn’t one of these reports for collection systems? I invite you to spend a few moments reviewing this report.
Mark... DID you submit your material on time and in accordance with the request from the BOS...???
If so, what was the response from the County...??? It is their ball game and they set the rules. No one gets a special case exemption or late submittal allowance, no more "do overs".... Ya either play by their rules or you sit by and watch...or go somewhere else to tryout...
Mark,
Two things about the 1st document you refer to ... they list these as "onsite" treatment options and they say that total nitrogen is reduced with your system, not that the nitrates are reduced to a specified level.
Where does your submitted documentation show that nitrates are reduced to desired levels over the long haul (say, 10 years)?
And ... no ... I'm not gonna read an entire 131M document (250 pages) just because you tell me to ... if you would point me to the pages which demonstrate your claims, it would be helpful.
Lastly, you ask why there isn't such a document for collection systems. Maybe it is because this document is associated with AB885, proposed new legislation and no one in the state has required a review of collection systems. If you wanna fight that battle you should take the issue up with the SWRCB and/or your legislator.
ps - do I get bonus watershed mark points if I quote wikipedia?
I will simply add from the same document as to the information source of the report:
"(1) information supplied by manufacturers, (2)
the results of independent testing and reporting, and (3) information reported in conference
proceedings and journals."
Which is the source for USBF?
Steve,
If you cannot demostrate a "linkage
" from the county's study report/WB treatment testing requirements why are you asking me for something that isn't in the county process?
We really need to sort out where and when the "10 years worth of data" REQUIREMENT came from and if that is even a hard and legal requirement, if you and Lynette want to try to use it to evaluate every system.
I love the manner in which Lynette sees a sewage hater behind every report. I suggest that you get your answers regarding the State Commissioned Report from the State or those responsible for submitting it.
It is certainly noteworthy that Lynette would ask me about the state's report, largely because she does not wish to believe anything I report. I love LO!
MIKE, I have been sending the county information, since late 2006.

Mark... Since you have been sending the County info since 2006, I would suspect they have answered you in some fashion...
Since you appear to be still complaining, I also suspect that you did not receive the answers you were hopeing for... I also suspect there was a culling of technology from the many, many variations out there and your presentation did not make the cut...
If your presentation was as disconnected as you appear on this blog; i.e. still not able to provide an answer to Ann asking for a simplified description of just "how" the ECOfluid works... then I would suspect the County decided not to pursue your product...
Sorry Mark, but since you are still blog marketing here, you apparently will not be one of the short list of providers... No product, design or sales pitch is a perfect fit for every situation... One would think that a good salesman would recognize that one market is closed and that it's time to move on to another area...
Mark sez:"We really need to sort out where and when the "10 years worth of data" REQUIREMENT came from and if that is even a hard and legal requirement, if you and Lynette want to try to use it to evaluate every system."
Ah, good question. Did that arbitrary 10 years first come from Roger Briggs in relation to the AWIPS "Ponds of Avalon" propsed by the original CSD? Was it based on valid scientific data or did Roger pull that number out of his . . . hat? and since nobody has questioned it (or have and been ignored) it simply became something "real." instead of a made up number.
Sorry MIKE, your suspicions are totally incorrect.
Mark and Ann,
Whether the 10 years was ex-rectum or not, it was the RWQCB laying down a standard they expected for a "solution". If a system doesn't have a 10 year track record of reducing nitrates, we won't get a SRF and we will potentially be on the hook for polluted groundwater if the nitrate levels don't drop.
Bureaucrats have the ability to interpret laws passed by others. Unless there is a lawsuit to overturn a particular rule developed by a bureaucracy, it is a de-facto law. Typically one also cannot sue until there is an official ruling. For example, if the LOCSD had wanted to sue the RWQCB over their 10 years rule way back when, they could have (but that would probably have been unwise for a variety of reasons).
So, we're in a situation where the County, if they select a system which will return any water to our aquifer, they will need to attain denitrification and they'll need to demonstrate that the technology selected has worked at denitrification over a long term.
So then Mark, did you submit a document that proves this method has that track record or is it just theoretically viable ... just like the AWIPS system which was eliminated from consideration because of no track record? This is not a hard question to answer. Your reticence makes me think that you don't have a long-run track record of 10+ years and this might be why they didn't even get back to you.
Why not call John Waddell and ask?
Steve,
The ECOfluid USBF has more than ten years N reduction behind it.
I see you cannot gave a foundational cite or law that supports your 10+ year N reduction requirement...
Mark,
Total N is not the same as nitrates. Perhaps this is why your device was not selected ... if you didn't show that nitrates were reduced, you were out of the running from day 1.
Steve,
Show me the "standard" you think needs to be met.
The standard, not from memory.
Doing so, should make things a whole lot more clear and less confusing.
You do realize that the county has published a request to build a "secondary" treatment plantfor up to $25M which can be upgraded to tertiary?
Mark... Plain and simple, what was the County's "Offical" response to your proposal to meet their specific request...????
Not this RFP for a "secondary treatment", but just the original RFP...
Mark sez:"I see you cannot gave a foundational cite or law that supports your 10+ year N reduction requirement..."
Law? Nope, just some staff member somewhere makes a number up and that becomes reality, whether it's scientifically right or not. If you object, go sue . . . hehhehheh
Mark,
Do your research yourself.
If you're gonna get all fussy at me for not reading the tome of documents you provide, you should at least be willing to look thru past news reports and RWQCB and LOCSD documents to find what you need.
My gosh ... don't complain about not getting your product chosen if you don't understand the parameters for selection.
Perhaps you misunderstand argumentation, rhetoric or the scientific method. Let's make some things clear.
The County is not obligated to use your device. They are not obligated to prefer your device just because you say you like it. You need to demonstrate to them that it is superior to others before it is a sure thing. To even be in the running, your device will need to meet certain criteria. Knowing those criteria is important.
I am not obligated to trust you or your claims of having the best wastewater processing device since sliced bread. If you want me to believe that your device is even acceptable for Los Osos, you need to go thru the County process and have them choose your device as a finalist. If you want me to believe that you've met the criteria for Los Osos, you need to provide demonstrable proof that your device will meet requirements stated by the RWQCB in the past.
If you want to doubt me that is fine. If you don't believe that your device needs to have a track record of nitrate removal, be my guest.
Just don't whine at me when you ask why your device wasn't chosen and I tell you a possible reason.
Amen!
ws mark doesn't get that the RFQ has been approved and that project teams with their systems can now ask to be on the list of those to be vetted for the D/B process. At last night's TAC meeting, Mark H. stated that at the initial meeting 60 contractors were present. Mark H. made it clear that the way the DEIR was structured, just about all possible project types fell in there somewhere, so any team that has the kind and quality of members (as stated in the RFQ) to build their type of project, they could throw their hat into the ring.
I don't think ws markis up to this though. He can't even get a simple statement on how his device works out to Ann.
Advanced Biological Wastewater Treatment
Effective Efficient Economic
state-of the-art ... an important environmental
engineering process revolution."
Dr. Lawrence K. Wang in a 1995 report to the United Nations Industrial Development
Organization.
USBF [Upflow Sludge Blanket Filtration] is the result of over forty years of
research, development, testing and practical experience. The technology is unique in
that it incorporates all of the advanced features of an extended aeration activated
sludge process, including superactivation, nitrification, single sludge denitrification,
phosphorus uptake, upflow sludge blanket filtration etc., in one compact unit for cost
effective wastewater treatment, landscape saving and easy operation. The result?
Highly affordable wastewater treatment with low maintenance and operating costs.
USBF has no inherent capacity limits and is used in a wide range of applications.
Many hundreds of plants serving the municipal and industrial wastewater treatment
sectors are in successful operation around the world. The USBF process is making
an impact on the wastewater industry and has established an impressive
international reputation for its design simplicity, and cost-effectiveness.
Building on the strengths of USBF, CES designs, builds and operates wastewater
treatment plants main features of which are capital and operating cost effectiveness;
high quality effluent; Class A Reclaimed water; easily retrofit to existing systems and
package plants.
PROCESS DESCRIPTION
Introduction
The USBF process is a modification of the conventional activated sludge process
that incorporates an anoxic selector zone and an upflow sludge blanket clarifier. The
USBF process may be designed for:
Carbonaceous (BOD) removal
• BOD removal and nitrification
• BOD removal, nitrification, and denitrification
• BOD removal, nitrification/denitrification and phosphorus removal
For carbonaceous removal, the anoxic zone serves as a "selector zone" that
conditions the mixed liquor to improve settleability and to control filamentous
organism growth.
For nitrification, denitrification and phosphorus removal designs, the anoxic zone
provides the necessary conditions for dissimilarity nitrate reduction and phosphorus
removal by "luxury uptake". In this process, Nitrosomonas and Nitrobacter bacteria,
oxidize ammonia nitrogen to nitrite and then to nitrate respectively in the aeration
zone. The nitrate is then recycled to the anoxic zone where it is reduced by
dissimilarity nitrate reduction. In this reaction, the incoming BOD serves as the
carbon source or electron donor for the reduction of nitrate to elemental nitrogen.
The phosphorus removal mechanism in this process is the same as that employed in
the Phostrip and modified Bardenpho processes. In the USBF process, fermentation
of soluble BOD occurs in the anaerobic or anoxic zone. The fermentation products
are selectively used or assimilated by a special group of microorganisms that are
capable of storing phosphorus. Soluble phosphorus is taken up by the population of
the phosphorus-storing bacteria (Acinetabacter) developed in the anoxic zone during
the aerobic stage of treatment. The assimilated phosphorus is then removed from
the system as excess biomass or waste sludge. The amount and rate of phosphorus
removal depends primarily on the BOD/P ratio of the influent wastewater.
Process Design
The USBF process is based on the Lawrence and McCarty kinetic models for BOD removal, nitrification and denitrification.
The USBF process is capable of removal of BOD5 to less than 5 mg/l, TSS removal
to less than 10 mg/l without filtration, total nitrogen removal to less than 1.0 mg/l and
total phosphorus removal to a range of 0.5 to 2.0 mg/l. Higher levels of phosphorus
removal down to 0.2 to 0.5 mg/l can be achieved by metal salt addition to the
aeration zone immediately prior to the mixed liquor entering the clarifier. A number of
metal salts may be used including Alum (Al2(SO4)3.14H2O), Sodium Aluminate
(Na2O.Al2O3), Ferric Chloride (FeCl3), Ferrous Chloride (FeCl2), Ferrous Sulphate
(FeSO4.& H2O) or Ferric Sulphate (Fe2(SO4)3). Since the bulk of phosphorus (over
80%) in the USBF process is accomplished by biological uptake, the small polish
dosages of a metal salt coagulant do not significantly increase sludge production.
For example, removal of phosphorus by FeSO4 is given by the two following
reactions:
Phosphorus Precipitation 3FeSO4 + 2PO4
-3 Fe3 (PO4)2 + 3SO4
-2
Alkalinity Reduction and Hydroxide Precipitation Fe+++ + 3HCO-3 Fe(OH)3
According to the above two reactions, removal of 2 mg/l of PO4
-3, would theoretically
produce 6 mg/l of additional sludge. In actual practice, a value of 5 mg/l of sludge per
mg/l of PO4
-3 removed provides a conservative design value. For an influent
wastewater having 240 mg/l of incoming BOD and a sludge yield of 0.6 lbs TSS/lb
BOD removal, and the use of FeSO4 to remove 2 mg/l of PO4
-3, the total increase in
sludge production would be about 7%.
The USBF process utilizes a unique patented upflow sludge blanket clarifier. The
upflow blanket clarifier utilizes a trapezoidal shape where the mixed liquor enters the
bottom of the clarifier through a specially designed baffle where hydraulically induced
flocculation occurs. The trapezoidal clarifier shape provides for a steadily increasing
surface area from the bottom to the top of the clarifier. This permits a gradually
decreasing vertical velocity gradient within the clarifier. The "top surface area"
clarifier overflow rate is 150 to 250 gpd/ft2 (6 to 10 m3/d/m2) at average daily design
flow. The clarifier is typically designed for a daily peak flow rate of 3 times the
average flow ratio which translates to a peak "top surface" clarifier overflow rate of
450 to 750 gpd/ft2 (18 to 31 m3/d/m2) which is very conservative.
The clarifier also includes a unique baffle arrangement to allow sludge withdrawal at
the bottom of the clarifier. The sludge withdrawal design also incorporates the
internal recycle between the aerobic and anoxic zone. The normal design
recycle/sludge withdrawal rate is 4 times the average daily flow. This high sludge
withdrawal rate from the clarifier bottom creates a downward velocity gradient within
the clarifier that significantly improves the hydraulic efficiency of the clarifier
compared to conventional clarifier.
The internal recycle between the aeration zone and the anoxic zone provides BOD
recycle that is required for endogenously supported nitrate reduction. This internal
recycle of mixed liquor also provides for recycle of phosphorus removal organisms
developed in the anoxic zone that are then carried into the aeration zone for
phosphorus uptake. The recycle ratio is established based on the influent BOD/total
phosphorus/ammonia nitrogen ratio. The recycle ratio of 4 provides for a 25% - 35%
safety factor for domestic wastewater.
The major process design parameters for this process depend on (1) wastewater
strength and biodegradability (2) wastewater temperature, influent and effluent BOD,
N, and P concentrations. Typical HRT's for the aeration zone range from 6 to 30 hrs.
The HRT's for the anoxic zone typically range from 1 to 2 hrs for a selector zone
used for carbonaceous removal and 2-8 hrs for biological phosphorus removal and
denitrification.
The design SRT is controlled by the temperature dependent nitrification and BOD
removal kinetics and the design effluent N-NH4 requirements. The operating SRT is
normally maintained at 50% to 100% greater than the design SRT at an operating
temperature to provide a safety factor and to accommodate changes in influent
wastewater characteristics. (Please note that SRT is both a design parameter and a
process control parameter).
Operating Parameters
The dissolved oxygen (DO) concentration should be maintained at 2.0 to 4.0 mg/l in
the aeration zone, and less than 0.2 mg/l in the anoxic zone. Under influent loading
conditions less than the design values, the HRT in both the aeration zone and in the
anoxic zone will be greater than the design value. Under these conditions, the mixed liquor
volatile solids concentration in the system will normally be reduced to meet the process
requirements. The DO may be maintained at optimum levels by reducing air supply. The
increased HRT in the anoxic zone permits more time for exertion of DO demand and
production of anoxic conditions needed for fermentation. The operating SRT is controlled
by the sludge-wasting rate. SRT is normally calculated based on aeration zone volume
and MLVSS concentration since BOD removal and nitrification kinetics control the aeration
zone volume.
Provision is made in the Ecofluid design for measurement of both the internal recycle and
sludge wasting. The operating SRT of the USBF process may be increased significantly
above the design requirements without sacrificing effluent quality since the "anoxic
selector" zone conditions the mixed liquor solids and the USBF clarifier provides a
"filtration/flocculation" mechanism to prevent discharge of pin-point floc normally
associated with high SRT systems. Alkalinity and pH If the influent wastewater is not
properly buffered, it is necessary to add alkalinity for nitrification and denitrification. The
nitrification reaction consumes 7.1 mg/l of alkalinity as CaCO3 for each mg/l of ammonia
nitrogen oxidized. The denitrification reaction produces 3.57 mg/l of hydroxide alkalinity as
CaCO3 for each mg/l of nitrate-nitrogen reduced. For an influent wastewater having 40
mg/l of NH4-N, the total alkalinity should be 150-200 mg/l to insure adequate buffering.
The pH of the system should always be maintained between 7.5 to 8.5 S.U. by the
addition of alkalinity when required.
COMPARISON WITH SBR*
General Considerations
Both the Sequencing Batch Reactor (SBR) and the Upflow Sludge Blanket Filter (USBF™)
are modifications of the Activated Sludge Process. The SBR was developed in the U.S. in
the late 1960's and became widely used during the 1980's and 1990's. The process
concepts incorporated into the patented USBF process were developed both in Europe
and the U.S. in the 1970's. Various forms of the USBF process concepts including "anoxic
selector zones", and "upflow blanket clarifiers" have been used worldwide for the last 25
years. Both the SBR and USBF processes are fully capable of treating municipal
wastewater to meet the U.S. and International Standards of secondary wastewater
treatment, (30 mg/l BOD, 30 mg/l TSS); advanced secondary treatment, (10 mg/l BOD, 10
mg/l TSS and 1 mg/l NHM4-N) and tertiary treatment (10 mg/l BOD, 10 mg/l TSS and 1.5
mg/l total nitrogen) standards.Both processes are designed using the same basic
biological treatment kinetics for carbonaceous removal, nitrification and denitrification.
Developed eveloped and refined kinetic design models for both processes based on the
approach of Lawrence and McCarty, which is incorporated into U.S. Textbooks in Sanitary
Engineering and in the USEPA Design Manuals for Wastewater Treatment and Nutrient
Control. A complete description of the kinetic process design models
Design Loading
Table 1:
Comparison of major loading parameters
The USBF process has been used in Europe under low F/M ratios (0.01 to 0.05) or
in the "super-aeration mode" to achieve very low removal of BOD and refractory
COD when necessary. In the US, the F/M loadings are increased for municipal waste
to the 0.1 to 0.3 ranges for BOD removal for municipal sewage and to over 1.0 for
high rate treatment of high strength industrial waste.
Design loadings (F/M's) for the SBR system are generally less due to the larger
aeration requirements since air is only supplied during a portion of the total SBR
cycle time thus increasing installed aeration HP. Because of the patented and unique
Sludge Blanket Clarification Concept of the USBF and the incorporation of an
"Anoxic Selector Zone", the operating Sludge Volume Index (SVI ml/g) for this
process is much lower than for the SBR. This is a critical factor in the overall
performance of this process.
and a detailed description of each process can be found elsewhere. This evaluation
will present a comparison of the two processes including:
• Design loading considerations
• Performance and operating parameters
• Power requirements
• Modular design considerations and mechanical component design
• Cost factors
Each of these is discussed in the following sections.
Performance and Operating Parameters
Table 2:
Typical removal efficiency of the USBF and SBR system.
A major feature of USBF is the combined advantage of an anoxic zone prior to the
aeration zone for "conditioning" the mixed liquor prior to the upflow solids contacting
the flocculating clarifier. The anoxic zone reduces or eliminates filamentous sludge and
provides a very low (80-120 ml/g) SVI. The anoxic zone operates in this fashion for
BOD removal and BOD removal plus nitrification. For denitrification, the anoxic zone is
increased in HRT and utilizes the endogenous carbon in the wastewater as the
electron donor for denitrification. In the SBR process, a separate carbon source
(commonly methanol) is normally added for denitrification. Unless methanol addition is
closely controlled, over dosing can lead to the discharge of excessive BOD. The USBF
process can reliably remove TSS to a slightly lower level (5 mg/l) than SBR (10 mg/l)
due to the better conditioned mixed liquor suspended solids (MLSS).
Power Requirements
From a process standpoint, USBF and SBR require the same amount of oxygen for
BOD removal and nitrification in accordance with accepted kinetic theory. Both
processes take advantage of the Nitrate Oxygen returned (2/3 of oxygen required for
nitrification) during denitrification.
The USBF process requires less installed HP than SBR because the SBR process
must provide the same amount of oxygen in a shorter period of time (i.e. during the
aerated fill cycle) and the aerated react cycle. The installed HP for a SBR is typically
30 to 50% higher than for the USBF process under the same influent and effluent
design conditions. The aeration efficiency of fine or coarse bubble aeration is also
greater for USBF than SBR since SBR average aeration depth is lower due to
Both processes respond well to peak to average hydraulic loading. The USBF
process addresses increased hydraulic loading by first producing a faster settling
mixed liquor due to the lower SVI and secondly, by the unique sloping sidewall
clarifier that allows the sludge blanket to rise automatically increasing the surface
settling area and by inter-particle flocculation in the upflow clarifier. The SBR
addresses increased hydraulic loading by adjustment of the settling cycle time.
decanting up to 30% of the aeration tank volume, which thereby lowers aeration
depth by 30%. At 30% decant, the average aeration efficiency of an SBR system is
85% of that achieved by a USBF system.
Modular Design Considerations and Mechanical Component Design
The USBF design is a continuous flow system incorporating the aeration zone,
clarifier and anoxic zone into a single tank. The only mechanical equipment required
is a blower for aeration and airlifting return sludge (in larger plants, a low HP axial
pump is used for sludge return). Waste sludge can be taken off the air lifted sludge
return line unless prohibited by head considerations.
The SBR system is normally a two-tank design and in addition to the aeration
requirements requires decanting by pumping from each tank. SBR's are also
normally equipped with separate sludge wasting pumps. In order to meet mechanical
reliability requirements, duplicate decant and waste sludge pumps are required for
each separate SBR tank. From a mechanical standpoint, the USBF system is much
simpler and requires much less rotating equipment. This provides a significant
advantage to USBF in:
• Original equipment cost
• Maintenance cost
• Operational simplicity
For example, airlift pumps rarely fail compared to mechanical pumping systems.
Although there are no size limitations on USBF or SBR systems, the USBF single
tank design better lends itself to higher capacity system design than SBR. Dual tank
SBR systems have generally been limited to 0.5 to 1.0 mgpd (1,900 to 3,800 m3/d)
volumes per tank due to decant pumping requirements. In standard SBR systems,
the decant rate is 7 to 15 times the average design flow. Over 98% of SBR systems
installed in the U.S. are under 1.0 mgpd (3,800 m3/d) whereas, USBF single tank
systems have been installed with up to 4.0 mgpd (15,000 m3/d) capacity.
Cost Factors
The capital cost of biological treatment processes are summarized below:
• The cost of constructed tankage to provide the required Hydraulic
• Residence Time (HRT) to meet the process kinetic
requirements. (These
requirements are the same for both processes).
• The cost of clarification tankage.
• The cost of the mechanical support equipment, including
pumps, blowers, internal
piping and decanting devices.
• Site, civil works and land area requirements.
• System control equipment.
• Electrical supply and equipment.
The USBF and SBR processes require the same basic tankage for the biological
processes since they are based on the same biological kinetics. The USBF is a single
tank system and the SBR is a dual tank system. The mechanical requirements for SBR
system designs are much greater than for USBF systems because of the requirements
for decant pumping and waste sludge pumping with duplicate units for each.
Clarification tankage is incorporated into the single tank design for USBF and into the
dual tank design for SBR's. The installed HP requirements for the SBR form of
treatment is much greater (30 - 50%) than for the USBF as previously discussed. The
electrical requirements including total power and power distribution is a first power
function of installed HP and is greater for SBR than USBF due to the greater number
and spatial distribution of electrical motors in the SBR system.
Both USBF and SBR are compact treatment systems compared to conventional
activated sludge or the oxidation ditch form of treatment. The site and civil works for
these forms of treatment are much less than for conventional secondary or advanced
secondary treatment. In terms of land area required, the USBF system requires
approximately 60-80% of the land area of the SBR system depending on layout.
Summary
The following is a summary analysis of the SBR and USBF processes.
1. Both USBF and SBR processes are proven to reliably meet all current standards for
BOD removal, nitrification and denitrification down to an effluent BOD level of <5.0
mg/l, TSS of 5-10 mg/l, NH4-N of 1.0 mg/l and a total nitrogen of less than 1.5 mg/l.
(Extensive operating data are available to document the above).
2. The USBF process requires less installed HP than the SBR process.
3. The USBF process has fewer mechanical components than SBR and therefore is
simpler.
The USBF process with anoxic zone treatment of mixed liquor produces an
inherently more stable mixed liquor, lower operating SVI's and slightly higher
removal efficiency for TSS.
5. The USBF system is more flexible in retrofitting existing plants than the SBR
because of the unique single tank upflow clarifier concept and design of the
USBF.
6. USBF generally has a smaller land area requirement ("footprint") than SBR.
7. USBF electrical and mechanical requirements are 20-40% less than for SBR.
8. Based on total process requirements including tankage, mechanical support
equipment, power requirements, electrical, controls, site work and land area
required, the USBF system has a significant cost advantage over conventional
activated sludge, the oxidation ditch form of activated sludge and SBR's for
treatment system sizes ranging from 1.0 to 50 mgpd (3,800 to 190,000 m3/d).

NUTRIENT REDUCTION
Nitrogen
Nitrogen is removed by nitrification and denitrification processes. Nitrification is
autotropic and all USBF integrated bioreactors are designed for complete nitrification
of ammonia to NO3. Denitrification however, is heterotropic and requires a carbon
source. Conventional plants' "separate-sludge denitrification" requires that carbon be
added typically in the form of methanol. This adds to operating costs and if used in
excess, increases effluent BOD5 content.
The USBF technology "single-sludge denitrification" approach uses an endogenous
carbon source to maintain the denitrifiers. Influent is combined with nitrified mixed
liquor in the anoxic compartment providing the carbon source needed for
denitrification. Relatively high (3 to 4 times average daily flow) nitrified mixed liquor
recycle rates are employed and sufficient denitrification retention times provided.
Total nitrogen reduction to below 10 mg/l is readily achievable.
Phosphorus
USBF technology delivers not only high efficiency of organic matter reduction, but
also increased efficiency of phosphorus removal. Three processes, "biological
uptake", "simultaneous precipitation" and "additional chemical precipitation" followed
by filtration are employed with advantages.
The mechanics of biological phosphorus uptake, known as "luxury uptake", is due to
exposure of activated sludge to alternating oxide and anoxic conditions. Under the
conditions, the cells store more energy in the form of phosphorus than needed for
their survival. If strictly oxide conditions are maintained during subsequent
clarification, phosphorus will be retained by the cells and will eventually be removed
with the excess sludge. Unlike most other methods of clarification, the USBF clarifier
maintains these conditions. Biological phosphorus reduction to less than 2 mg/l is
achievable 1.
For further phosphorus reduction, chemical precipitation followed by filtration is used.
In most domestic wastewater phosphorus is present in three forms, orthophosphate,
polyphosphate and organic phosphorus. Polyphosphate and organic phosphorus
cannot be readily precipitated however, during the biological treatment they are
converted to orthophosphate, which can.
Aluminum sulfate, ferrous sulfate or other metal salts are used as precipitants.With
onventional systems, chemical dosing and precipitation typically takes place in a
dedicated system following the biological treatment. However, in the USBF process
are advantageously dosed into an anoxic compartment and precipitation, coagulation
and flocculation take place within the USBF bioreactor ("simultaneous precipitation").
Continuous sludge circulation and mixing within the bioreactor ensure efficient
precipitation with an additional benefit of increased efficiency of the USBF clarifier.
Since the bulk of phosphorus reduction (up to 80%) is accomplished by biological
uptake, the small polishing dosage of metal salt precipitant does not significantly
increase sludge production. Divalent ferrous sulfate has some additional advantage .
Since the anoxic conditions prevent oxidation of divalent ions to trivalent and the
subsequent formation of ferric hydroxide, more of Fe ions are available to react
withorthophosphate. The advantage2 is reduced chemical consumption (close to
stochiometric) and reduction of ballast sludge production3. Reduction of total
phosphorus by simultaneous precipitation to less than 0.5 mg/l is readily achievable.
Reduction of total phosphorus to less than 0.1 mg/l is eminently possible but may
require additional flash mixing and precipitation prior to filtration ("additional chemical
precipitation")
1Sludge decant return from storage or dewatering to bioreactors if such is the case must be chemically
treated as anoxic conditions during quiescent periods will cause phosphorus release.
2Caution must be exercised if coagulation/flocculation and filtration is followed by UV disnfection.
3By contrast, dosing compounds containing divalent Fe ions within oxide conditions allows their
oxidation to trivalent and subsequent hydrolysis. Since both take place faster than mixing and
precipitation, the result is formation of ballast ferric hydroxide and increased chemicals consumption.
Summary
Features
The patented USBF technology incorporates three innovative features that increase
efficiency and reduce costs:
Upflow Sludge Blanket Filtration Clarifier
Sedimentation is the most commonly used separation technique today. Its low
specific rate of separation makes it slow and inefficient promulgating the need for
large tanks and other equipment. USBF technology has a substantially higher
specific rate of separation using a prism or cone shaped clarifier. Unlike conventional
clarifiers, the influent enters at the bottom through a specially designed baffle where
hydraulically induced flocculation occurs.
The prism or cone shape provides for a steadily increasing surface area from the
bottom to the top resulting in a gradually decreasing vertical velocity gradient within
the clarifier. As the velocity gradient decreases, flocculated particles form a filtering
media. The design incorporates internal recycle between the clarifier and anoxic
compartment Typical recycle rate is 3-4 times the daily flow. This high sludge recycle
rate creates a downward velocity gradient within the clarifier that significantly
improves the hydraulic efficiency of the USBF clarifier compared to conventional
clarifiers.
"Superactivated" Sludge Process
Most traditional plants operate at low or medium sludge concentrations. USBF plants
operate at higher concentrations, creating conditions that increase the number of
microbial cells searching for "food" - organic matter in the incoming wastewater. By
keeping the biomass hungry or "superactivated" the nutrient-deficient microbial cells
"feed" on wider range of available organic material, including some previously
considered non-biodegradable.
All Processes Integrated into One Reactor
Most conventional technologies carry out aeration, nitrification, denitrification,
clarification and sludge stabilization in a number of dedicated vessels. By contrast,
USBF technology can carry out all these processes inside one compact bioreactor,
substantially reducing equipment size and costs.
Process
The operation of a USBF plant is simple and self-regulating. Wastewater enters the
anoxic compartment of the bioreactor where it mixes with activated sludge recycled
from the bottom of the clarifier. Mixed and moved in a plug flow manner, the mixed
liquor eventually flows into the bioreactor's aeration compartment. After aeration, a
stream of the mixed liquor enters the bottom of the clarifier where sludge flocs and
water are separated by upflow sludge blanket filtration. After separation, treated
effluent overflows into a collection trough and is discharged from the system. To
complete the internal circulation loop, activated sludge collecting at the bottom of the
clarifier is recycled back into the bioreactor's anoxic compartment.
Benefits
Reduced capital cost
Single integrated bioreactor concept reduces auxiliary equipment and built-up land
requirement.
Reduced operating and maintenance costs
The compact design, minimal moving parts, modular construction and self-regulating
hydraulics result in reduced supervision requirements contributing to lower operating
and maintenance costs.
High treatment efficiency
Reductions of BOD5 and TSS to les than 10 mg/l and ammonia to less than 0.5 mg/l
are readily accomplished. Treatment includes biological reduction of nitrogen and
phosphorus.
Stabilized sludge with less excess
Minimum design sludge age of 25 days produces aerobically stabilized sludge and
less excess is generated.
No odour
Aerobic conditions throughout the bioreactor and extended sludge age dramatically
reduce the potential for odour. Plants can be located in the vicinity of populated
areas without any ill effect.
Hydraulic flexibility
The clarifier's prism or cone shape facilitates superior hydraulic flexibility. USBF
technology accommodates high peak flows and flow swings in a self-regulating
manner - the higher the flow, the higher sludge flocs rise and the larger the filtration
area becomes.
Modular and flexible design
Modularity of design ensures that plants meeting current needs can be quickly
expanded if and when growth demands. A variety of construction materials are used
and plant components can even be retrofitted into existing tanks.
Improved sludge dewatering
Extended sludge age improves its structure and mechanical dewatering
characteristics.
No primary clarification
USBF technology does not require primary clarification. For larger units, screening
and grit removal is all that is required prior to biological treatment.

For MIKE, STEVE and Lynette,
I hope this helps you understand the "process".
Steve,
N Removal isn't the issue with most processes. Consistency is the goal.
Yes Lynette,
I understand the county's "process".
MIKE: I understand the county's process.
Where is the county's discussion/explanation?
If there is a simple way to say it, it might be said like this:
Most conventional technologies carry out aeration, nitrification, denitrification,
clarification and sludge stabilization in a number of dedicated vessels. By contrast,
USBF technology can carry out all these processes inside one compact bioreactor,
substantially reducing equipment size and costs.
No, N removal isn't what all processes must focus on, but Los Osos is on the edge of the Morro Bay National Estuary, plus California is pretty tight on regulations regarding water and wastewater. For us low N # consistency is the goal. Try reading the DEIR. Page 2-7 you will find that the numbers allowed in effluent must not exceed 7 mg/L total nitrogen (as N) monthly average and a daily maximum at 10 mg/L. Central Coast Regional Water Quality Control Board Order No. R-3-2003-0007.
I didn't see how this would save us on the collection system - actually, what IS the collection system?
Ann, was the above giant posting what you were looking for?
USBF – NUTRIENT REDUCTION
USBF Nutrient Reduction Page 1 of 1
NITROGEN
Nitrogen is removed by nitrification and denitrification processes. Nitrification is autotropic and all USBF
integrated bioreactors are designed for complete nitrification of ammonia to NO3. Denitrification however, is
heterotropic and requires carbon source. Conventional plants’ “separate-sludge denitrification” requires that
carbon is added, typically in the form of methanol. This adds to operating costs, and if used in excess, it
increases effluent BOD5 content. USBF technology “single-sludge denitrification” approach uses an
endogenous carbon source to maintain the denitrifiers. Influent is combined with nitrified mixed liquor in the
anoxic compartment providing the carbon source needed for denitrification. Relatively high (3 to 4 times
average daily flow) nitrified mixed liquor recycle rates are employed and sufficient denitrification retention
times provided. Total nitrogen reduction to below 10 mg/l is readily achievable.
The discussion above is important to those responsible for selecting wastewater treatment technology.
Bottom Line Mark... "Assuming" that you actually applied to SLO County's RFP, what was the County's reply...???
No matter how many 1995 articles you cut and paste, this blog is not going to decide whether the ECOfluid system will or will not be part or whole of the Los Osos waste water treatment...
Mike-
You have to remember that WS Mark is not a wastewater "expert" any more than he is a meat product "expert", gold mine "expert", or asset management "expert" (or any other product he is hawking online.)He is just a guy trying to make a buck without working. So, consider the source...
MIKE:
I think you mean RFQ.
Those are Due in February aren't they?
ABS,
Why so bitter?
