For the past dozen years I’ve tinkered with the operation of nearly every municipal treatment technology that exists. It has been my experience that even the most resistant designs can be operated differently in order to provide a lot of nitrogen removal.
Doing so requires: (1) ongoing data collection and review; (2) a fundamental knowledge of nitrogen removal, and (3) frequent process adjustments.
Of late, I’ve been providing the service as a consultant. Meaning, I’m coaching. My biggest challenge is getting folks to change their routine. Change can be hard. I often get some push-back as people are resistant. At first. After a little success, it is a rare operator who doesn’t get a taste for it. “Besting” a design engineer is a pretty sweet experience.
Making process changes to improve nitrogen removal, generally provides for some nice side benefits. Some examples: less foam in the aeration tank, better settling sludge, less WAS, opportunities for better managing storm flows. Since we often turn down aeration and internal recycling equipment, operators often realize O&M savings. This means less money spent on electricity. And, it means less fuel used to generate electricity – and, a resultant reduction in the treatment plant’s carbon footprint.
Here’s how we do it.
Field testing
The foundation to effective nutrient removal is a fundamental knowledge of the bio-chemistry, daily or more frequent data, and ongoing operator attention and adjustment. Why are these so important?
Effective nitrogen removal requires the right mix of a number of variables.
Data is needed in order to optimize. The best information comes from on-line instrumentation: 24/7 data – the right parameters monitored in the right places – provide the very best process control information. With experience, an operator can quickly and effectively evaluate operating conditions and make the right process changes. But, without experience, the data can be more confusing than helpful.
The quality of the data is not as important as is timeliness. I have effectively operated any number of treatment plants using test strips to measure ammonia, nitrite, nitrate, and alkalinity.
Ongoing adjustments
As discussed below, the two main process steps – nitrification and denitrification – are more interdependent than not. Changing one may impact the other.
Ammonia removal is the first order of business
When optimizing nitrogen removal, operators are advised to always remember that ammonia must first be converted to nitrate. Nitrate cannot be converted to nitrogen gas – and nitrogen gas cannot be removed from wastewater – unless the ammonia is removed. For the inexperienced (I’m speaking from experience here), this can be easy to forget.
Operators will have more success with ammonia removal when optimal conditions exist. This is not a matter of having the right technology. Nope, it is all about providing bacteria with as close to ideal conditions as possible. Nitrifying bacteria perform best with:
- Sufficiently high dissolved oxygen concentration (but not too much or nitrate removal will be affected)
- Adequate alkalinity (since denitrification “gives back” 50% of the alkalinity consumed during nitrification, optimizing ammonia removal often requires effective, consistent nitrate removal)
- A high enough sludge age / MCRT (mean cell residence time) – and – a low enough F:M (food to microorganism ratio) to keep the aeration tank fully populated with nitrifying bacteria
- A long enough hydraulic retention time for nitrifying bacteria to effectively oxidize ammonia to nitrateNitrate removal follows ammonia removal
Denitrifying bacteria will most effectively remove nitrate when they are provided an ideal habitat for nitrate removal. In this regard, they are no different from nitrifiers. It’s where the similarity ends. Denitrifying bacteria perform best with:
- As low of a dissolved oxygen concentration as can be attained without adversely bringing down the DO in the aeration tanks where nitrification occurs
- Enough soluble BOD to “feed” nitrate conversion to nitrogen gas (the textbook value of 4 parts BOD to 1 part nitrate is often not enough; all BOD is not the same and constantly changing conditions require more than textbook BOD)
- A long enough hydraulic retention time for denitrifying bacteria to effectively reduce nitrate to nitrogen gas
- A proper return rate of nitrate laden mixed liquor; more on this below
DO control, made complicated
The optimal dissolved oxygen concentration (i) provides enough DO for complete ammonia removal during aeration, while (ii) keeping the DO down for nitrate removal under anoxic conditions.
The right amount of DO for ammonia removal is neither a fixed number nor is there any “best” way to adjust DO. Guidelines exist, but we don’t fret over being “in spec.” We’ve gotten ammonia removal in plants that maintain DOs that remain below 1.0.
Similarly, I’m not a believer in a “right” DO for nitrate removal. Well, not a fixed number. Fact is, I really like anaerobic conditions. But, I won’t get into that here; it’s a topic for another day.
Our approach to DO is something of a trial and error process. The first order of business is to provide enough aeration to fully nitrify. Meaning, setting operations so that the effluent ammonia concentration is consistently 0.5 mg/L or less.
After complete nitrification is established, adjustments to the DO are made to optimize nitrate removal.
Generally, this is most easily be done by cycling the air in the aeration tank. We generally begin with 4 hours of aeration followed by ½ hour of no aeration. Often, this involves installing timers. After a week or two of operation, we reduce the run time. This is repeated until there is just enough aeration to maintain effective ammonia removal.
Understand and control nitrate recycle pumping
An easy and effective way of controlling the dissolved oxygen concentration in both the aeration and anoxic tanks of a MLE (Modified Ludzak-Ettinger) facility is to adjust the nitrate recycle pumping rate. This is REALLY IMPORTANT. And, understood by few people.
Lowering the pump rate improves DO in BOTH the aeration AND the anoxic tanks. Both locations.
A higher, more stable DO is achieved in the aeration tank because the volume of low DO anoxic return that must be raised to a higher DO for nitrification is reduced. A lower, more stable DO is maintained in the anoxic tank because the volume of high DO nitrified waste that flows into the anoxic tank is reduced.
Contrary to what the books and the really smart people who write them say, it has been my experience that turning down the internal recycle rate to 1Q (100% of influent flow) is a good thing for nitrate removal. Mathematically, it doesn’t work so well. But in the field it sure does. Partly, I believe, this is because of the positive impact reducing the return volume has on DO. But more, I believe, because of the positive impact reducing the internal recycle rate has on the aerobic and anoxic hydraulic retention times.
At lower internal recycle rates, the mixed liquor spends more consecutive minutes in the pre-anoxic environment and more consecutive minutes in the aerobic environment. These longer retention times, I believe, allow bacteria more time to acclimate and grow. And, as a result, provide more efficient ammonia and nitrate removal.
Whether my theories are correct or not, the results are real. To improve nitrogen removal, we encourage operators to experiment with different internal recycle rates. Recently, I asked an operator to put both internal recycle pumps on minimum and to operate them only 50% of the time. This, while the aeration blowers are shut off 30 minutes and run for 120. He’s getting better numbers, less foam, and saving big bucks on electricity.
Deliver BOD when and where it is needed for denitrification
Nitrate removal is oftentimes limited because of a lack of BOD; soluble BOD. Operators, by thinking and acting “out of the box,” can import BOD to where it is most needed: anoxic tank. The most cost-effective way of adding necessary BOD may be to accept more septage. In addition to delivering rocks, rags and grit, septage trucks carry a waste rich in soluble BOD. Septage can be just the ticket for nitrate removal, and, haulers will pay for the privilege of dumping.
Another cheap and easy way of getting more BOD into anoxic tankage is to “de-tune” primary treatment. Of everything we do, this may cause regulators the most heartache. But, I’m finding this to work so well, we’ve trademarked a name for it: Drover ProcessTM. The idea is to overload, mix, or bypass a portion of primary treatment in order to increase the primary effluent BOD to the point where there is enough BOD getting through primary treatment to fully drive the denitrification process.
I believe that primary clarifiers 20 years from now will perform quite differently: still remove inorganics and float, but very inefficient BOD removing machines. Another issue for another day…
When too much of the BOD is insoluble, it needs to be solubilized before it will drive denitrification.
This can mean a short burst of aeration is necessary. When we can (eg., dual mixer oxidation ditch), we do.
Because fluctuations in influent t-N affect the amount of soluble BOD that needs to be added, and because not all BOD is available for nitrate removal… We find it best to provide considerably more than the textbook four mg/L of BOD for every mg/L of nitrate that needs to be removed. Something close to double the ratio is ideal.
We do not like having clients pay for carbon unless there is no way to get it for free. I particularly object to importing explosive products (alcohols). So… We work with operators to experiment with other sources of “free” BOD such as side stream wastes such as gravity thickener overflow. Other options include returning a portion of anaerobic or fermented waste sludge to the anoxic zone: be it primary sludge, waste activated sludge, or a combination of the two.
Empowering operators
As mentioned at the beginning of this overly wordy blog entry, change is not easy. But the operators I’ve worked with have gotten a lot of pleasure out of modifying their processes to improve nitrogen (and phosphorus) removal.
I look forward to the day – my “mission” – when design engineers, academia, and environmental interest groups become more supportive of wastewater treatment personnel. I believe it appropriate to expect operators to optimize.
I’m now off the soap box. And, back to the bar stool.
Thanks for reading.

Like my father before me, I like country music.
My interest in C&W is something of an acquired taste. When a Kansas preteen, it was most uncool to listen to anything other than the top 40 music played on KLEO 1480 AM radio. One summer, to show my commitment to pop music, I joined in the competition to suntan the radio station’s call letters on my body.
With the advent of FM radio, I got hooked on “southern rock.” My favorite bands being Pure Prairie League and, some years earlier, the Lovin’ Spoonful. At one time, I pretty much owned everything these bands ever recorded. Other favorite bands included: Ozark Mountain Daredevils, Crosby Stills & Nash, and Marshall Tucker.
The evolution is complete. Nowadays I listen to two kinds of music: country and western.
I like the sound and the stories. Although not technically a “country and western” song, Dan Hick’s & His Hot Lick’s 1970s tune “How can I miss you when you won’t go away?” pretty much epitomizes what country music is all about. It remains my all time favorite song title.
Which brings me to another, somewhat relevant, expression – “you can’t get up if you don’t fall down.” Montague (Massachusetts) plant superintendent Bob Trombley recently used this expression to describe his process control strategy. Let me put it in context.
Bob and Chief Plant Operator John Little – a serious misnomer; John is something like 6’4” and 230 pounds – have been experimenting. Not satisfied with single digit effluent TSS and BOD, they and the rest of the Montague staff are constantly experimenting. They’ve been able to remove 50-75% of the incoming nitrogen and a goodly percentage of the phosphorus. Call it their gift to the environment.
For their ratepayers, they’ve slashed sludge disposal and electrical expenses.
Their improvements have not come without some setbacks. In fact, that’s how I became involved. They got to a point where they wanted some outside help. Their philosophy? You guessed it, “you can’t get up if you don’t fall down.”
A good lesson for us all. Even almost 60-year old cynics such as myself.

Several years ago, one of the auto companies – Ford, I think it was – advertised that “Quality is Job 1.” If my memory serves me correctly, some of the television ads punctuated the statement with a loud sound as the word “Quality” was stamped onto a car or truck. It was an effective slogan.
Any number of organizations promote workplace safety with the theme “Safety is Job 1.” Maybe you have one or two such posters adorning the walls of your wastewater treatment plant.
Which brings me to ask; “As wastewater superintendent, what is your highest priority?” What is “Job 1” at the treatment plant?
Most of us, I’m betting, believe it to be permit compliance. Or, more generically, environmental protection.
At the risk of getting my workplace TP’d*, I disagree. Environmental protection is a critical component of what we do, but I respectfully submit that serving the needs of our community is our highest priority. Environmental protection is a component of community service; a very important component to be sure. But, the highest priority, I submit, is providing wastewater service so that the community can prosper: to effectively and efficiently meet the community’s need for wastewater collection, treatment, and disposal services.
The difference is important.
If environmental protection is job 1, then there is no limit on cost. Our job would be to spend as much money as necessary to make the environment better. And, better. And, better.
If community service is job 1, then it becomes our job to protect the environment at the least possible cost. That is, to optimize. And, compromise. (Compromise, for the record, is not one of my strong suits.)
I’m in the profit business. I pay my bills using money my company makes by assisting municipal wastewater superintendents protect the environment in the most cost effective way. I believe, perhaps naively, that making clean water affordable means that more water will be clean. Which, in turn, means that providing community service is more environmentally sustainable. But… maybe I am just coming up with justifications for what I do.
Regardless. I’ll keep promoting the notion that the most effective wastewater treatment plant operators are those that “tinker” with their facilities in order to produce the highest quality effluent at the least possible cost. To those that do, here’s hat’s off to you.
Thanks for reading.
*Explanation. TP’ing, for those of you who didn’t grow up in the Midwest in the ‘60s, is the practice of looping rolls of toilet paper into trees. A high impact, but otherwise harmless, prank.

To generate work, my company sends out postcards touting our “brilliance.” Because we are so doggone smart, we make technical presentations at seminars. Some are even worth listening to.
In an effort to keep existing clients happy with our service, we give them our best effort. When we have a story worth telling, we write it up and share it with upper management. We’ve found that people like it when we tell their bosses how they have improved operations without spending much money on new equipment.
On occasion, we’ve been known to buy a pizza or two. Meaning, as consultants go, we are at the cheapskate end of the spectrum.
When I was a municipal wastewater administrator, I partook of some wining and dining. At one WEFTEC conference, my wife and I were treated to an outlandish five course meal at a fancy, big-city rooftop restaurant. Somewhere during the meal, I got a bit uncomfortable with the extravagance.
I’ve found that I’m not the only person that would rather not be showered with gifts.
One plant superintendent told me about how he and one of his staff were taken to a strip club by his municipality’s design engineer. The consultant was plying them with drinks and bills. An odd way of generating wastewater design business methinks.
A consultant I hold in very high regard for his technical expertise once confessed that he had employed women to entertain clients. This man, a sad neurotic genius, is long ago retired. Maybe his story is the reason I’m so tight with the buck; his is not a situation I want to find myself in.
My opinion: municipalities deserve wastewater treatment plants that are reliable, efficient, effective. Like many others in the business, that’s the service we attempt to provide. On occasion, we get one right. And when we do, it is that reputation – a proven ability to deliver quality – that we want to be the measure by which we are judged. Or, maybe if I were more entertaining and a lot better looking, I’d be all for using the social skills I don’t have to dazzle potential clients.
I’m realistic; or, somewhat so. As mentioned in one of my first blog entries, getting public recognition for a job well done is something that so rarely happens in our business that, with time, most of us pretty much give up hope for. We are the poster children for under-appreciated service, are we not?
But.
Peer recognition is different matter. Most wastewater professionals know quality when they see it. As a guy like you – that is, somebody just doing his best to make affordable clean water – it feels really good when a client is truly satisfied with the work.
It’s almost as good as getting paid.

The Water Planet Company is hiring. We’re looking for mature, reliable people to train as wastewater treatment plant operators. Some need to be licensed, others not.
Unlike last year, we are not posting anything on Craig’s List. When we did, we received over 100 replies. An excellent response. The problem was the quality of the replies.
A few people wrote using complete sentences with proper capitalization, punctuation, and spacing. Of these, several correctly spelled all words! Most applicants sent marginally coherent replies. For ha-ha’s, I kept a few of the more notable emails. A sampling – with names and phone numbers changed – follows.
To Whom It May Concern: Is the wastewater position available? I’d be interested in hearing more about it. You can reach me at my e-mail address or phone (XXX) XXX-XXXX.

As a reward for attaining the age of 50, American doctors wish to subject you to a colonoscopy. It’s a marvelous thing. First, you buy a chemical that you mix with huge quantities of water. You drink the solution and hover over the toilet as the remnants of your last year’s food intake drains out of you.
The next day, your friendly doctor’s staff asks you put on an open-in-the-back Johnny and wheels you into a freezing cold room. There, while mercifully sedated, your friendly doctor sends a camera sent up your behind until it arrives in Saint Louis. Unless, of course, you live in St. Louis, in which case the camera stops at Houston.
I’ve twice had the pleasure. Honestly, it wasn’t that bad. Self induced diarrhea is not pleasant, but what came out of me was nothing compared with what I’ve “experienced” when working in wet wells, headworks structures, and while cleaning anaerobic digesters. During the procedure, I was deeply asleep and for once it was somebody else checking out my pipes.
A colonoscopy is done in the off chance that sleepy, little tumors like the one cut out of my woman last week are hiding inside of us. If they are, they can be removed before they blossom into killers. Last week wasn’t fun for her, but my woman now has the opportunity to live past 60. Meaning, the process was one of the best things she ever did.
At the hospital, my bedside chair faces a vital signs monitor. Information is displayed in the room and at the nurse’s station. If conditions fall outside of a pre-established range, an alarm sounds: locally and remote. No hospital worth checking into would attempt to care for a post-surgery patient without monitoring vitals. And, no intensive care ward would be without remote alarms. The real-time information provides fundamental health care information.
Not unlike the on-line instrumentation, PLC, and SCADA control loops that serve an important role in increasing numbers of municipal wastewater treatment plants. My recent hospital experience reaffirmed my belief in the appropriateness of on-line wastewater monitoring equipment.
More than that. Optimizing wastewater treatment, maximizing efficiency, providing the best possible effluent quality requires real-time water quality data.
Depending upon permit conditions, some of the most important parameters that should be continuously monitored include: influent pH, ammonia, and ortho-phosphate; aeration tank dissolved oxygen (DO); anoxic tank ORP; mixed liquor TSS; clarifier sludge blanket depth; and effluent ammonia, nitrate, ortho-phosphate, pH, and TSS.
It makes no more sense for a municipal superintendent to operate wastewater treatment equipment without the benefit of on-line, real-time monitors than it does for a community hospital to forgo vital sign monitoring equipment in favor of high-tech MRI and other diagnostic equipment. So I think.
Thanks for reading.

PS – If you are of age, and have not done so, please call your doctor today. Have a colonoscopy. More importantly, convince the ones you love to have theirs. With the cancer removed, I look forward to the opportunity for sharing a lot of sunsets that I would otherwise have viewed without anyone at my side.

As a public service, I am today writing to dispel some unfortunate rumors.
First, stand by while I tuck my tongue in my cheek. Meaning, I’ve being cynical here.
Federal and State Regulators do not routinely bring loaded firearms into meetings to “negotiate” consent agreements with municipal wastewater utilities. To think so is absurd. Let me explain…
Municipal wastewater administrators are very aware of federal budget problems and, like all red blooded Americans, wish to reduce deficit spending. In the spirit of governmental transparency and political bipartisanship, municipalities are happy to take on additional financial obligations.
Enlightened municipal officials – that includes treatment plant supervisors, staff, and all involved in wastewater treatment – actively pursue opportunities to spend tens of millions of dollars to, for example, reduce effluent phosphorus from 0.2 mg/L to 0.1 mg/L. The “consent agreement” format gives us a venue for doing so.
Conspiracy theories notwithstanding, the following series of facts have no relationship to one another.
Consent agreements typically require municipalities to hire engineers to design solutions to permit compliance issues. Design engineers usually receive 15-20% of total project costs. The vast majority of municipal wastewater treatment plants are custom designed. Project costs average in the millions, maybe tens of millions of dollars.
It is a total coincidence that the vast majority of non-municipal wastewater treatment facilities are pre-engineered, package plants, and that these treatment plants cost far less than custom built designs.
As promoted by the Water Environment Federation’s Water is Life and Infrastructure Makes it HappenTM campaign, equipment, not wastewater treatment plant staff, make the difference. You and I are less important to effective wastewater treatment than are equipment manufacturers, engineers, and regulatory personnel. It is they, not us, that “make it happen.” Go to the Water Environment Federation (your organization) web site to learn the “truth.”
Finally, and I’m removing tongue from cheek for this one, the 15,000 people best suited to decide what is best for the municipal wastewater treatment plants in this country are the superintendents of America’s 15,000 municipal wastewater treatment plants. You have the right – I say the obligation – to direct those of us who work for you.
As much as I’d like to convince you (and me) that I’m uniquely able to put your municipality’s needs above those of me and my company. Fact is, I do think I’m unique. But, really, not so… Don’t let the hired help tell you what is good for you when you know better than us. But do let us help you get there.
Thanks for reading.

I’m not much of a shopper. Last time I’ve been inside of a mall was maybe two years ago. I can’t remember. I do, however, regularly frequent Walmarts. And, Lowes. Love ‘em both.
I also go grocery shopping. Solo. No tag team shopping for me.
Last week, as I was negotiating my way through the produce section, I could not help but notice a fellow shopper. She was covered head to toe in black cloth with only a slit for her to see through. Yup, a burkha. With her was a boy of four or five years.
I was intrigued, but not very comfortable with the situation. Afterward, I talked about it with a few people. They confided that they wouldn’t feel all that comfortable being in a store with a burkha wearer either.
I’m fine with people who dress differently. Hasidic Jewish men stand out because of their traditional hair and clothing styles. Indian women wear colorful print shawls and often have a red spot on their foreheads. Amish not only dress differently, they travel by horse and buggy and live without electricity. Some men, for religious reasons, wear turbans. I don’t know about you, but people like this don’t blend in with others in my neighborhood.
These folks believe strongly enough in something to be different. I may not share their values, but they have a right to look and live and they wish. Some – the Amish, for example – impress me. I admire their courage, commitment, and resolve. So, good for them. Good for diversity.
If you are waiting for me to make a connection to wastewater treatment, I’m not going to. There is no connection. Not to wastewater. Not this time.
Nope, it is the DISconnection that concerns me. Not “concerns,” more than that. The burkha represents the enemy: a group of people who wish you and me dead. Far from all of them want me dead, I realize. But, more than a few do. Me, I don’t wish harm to anyone – well, not anyone that prevents me and mine from living our lives. But, I don’t want to be naïve either.
When you come across someone in your neighborhood wearing a burkha, it is hard to tell yourself that everything is hunky dory.
Here are some of the thoughts that went through my head when I pushed my grocery cart around the woman in her burkha.
Cool, I’m looking at my first burkha. I wonder why she is wearing that thing here? My, what a cute boy. Maybe I should chat her up. No, Grant, she is wearing the black wrap because she wants me to know that she does NOT want to talk to me. It may be against her religion for an unaccompanied man to talk to her. Doing so could, in her mind, be a sin. Fact is, Grant, she’d prefer you to be further away from her, not closer. So, move on.
The thinking then went something like this.
Hey, this Stop & Shop is what, one mile from a nuclear submarine base? Who is her man? Where is he? Is he friend or foe? Not likely a friend. Likely, best is neutral to my existence. At worst, yipes! I wonder what would happen if she walked into a bank with that thing on?
Aye-yi-yi.
More later.

I attended a municipal sewer authority meeting this week. It wasn’t my first. Not by a long shot. A group of civic minded volunteers authorized the spending of nearly $10 million. As these things go, it is a small project. As board members go, this group is enthused and engaged. They are working hard at what they believe best for their community.
In an effort to secure a 25% grant and 2% loan, the municipality voted to hire lawyers at a cost of $465,000. And, engineering services totaling $1.8 million. The regional health district will receive $494,000 to monitor construction.
Not counting the health district’s “force account expenditures,” the professional services overhead makes up 22% of the total project cost. Spending 22% to save 25% seems like a pretty good deal, especially since some engineering and legal work needs to be done, regardless of the funding source, does it not?
No. Not really.
But, by no means is this the “fault” of the volunteers who sit on the sewer authority. They are doing what they are supposed to do: put their faith and trust in the government agencies that exist to serve them and rely upon the professional guidance that the professionals they employ give them.
Fact is, there is not so small hidden cost that nobody told them about: the inflated cost of compliance with federal and state Clean Water funding requirements. These costs cause project costs to skyrocket. Please read on…
We don’t partake of Clean Water funds. Our clients fund our work without big government money. You’d think it would cost them more. It should. But, since the system is broken, they realize huge savings. If we can’t deliver a project for a 75% savings, we take a pass. Yes, you read correctly. We get the job done for one-fourth the cost of traditional Clean Water funded projects, or not at all. Make no mistake, our designs are not “cheap.” We are very big on instrumentation; more so than most design engineers. To save clients money, we use pre-engineered, pre-fabricated components. Mostly, we save client money by reusing existing equipment differently.
And, we get the job done a LOT faster.
The municipality mentioned above has spent a decade getting their funding application approved. For the past ten years, the pollution that the project is supposed to remove has been ongoing. Now, ten years later, and at a considerably higher cost than going it without Uncle Sugar, the municipality is finally about to get a shovel in the ground.
If you need your toilet paper holders made of brass and curbing made of granite, feel free to stand in line for some Clean Water funds. If you want a treatment plant that does an outstanding job of making clean water, faster and less expensively, go without federal and state funds.
Better, give me a call. Let me show you what we can do.
Thanks for reading.

I’m an animal lover. Plants, too.
My children were raised in something of a zoo. In addition to dogs and cats, we had rabbits, ducks, chickens, guinea fowl and turkeys. We had millipedes, hissing cockroaches, salamanders and newts. We bottle fed an abandoned raccoon before returning him to the wild. Our collection of fish, sea monkeys, and turtles included a small snapper my daughter named “fluffy.” We had a chinchilla, a hedgehog and ferrets. Snakes, hamsters and guinea pigs. And, then there was that pair of nasty geckos that only my son would handle – with leather gloves.
Of the many dogs in my life, I most fondly remember Queenie and Zeb. Queenie, a Llewellyn Setter was a great childhood pet and an equally marvelous hunting dog, bobwhite quail being her specialty. Zeb was as devoted of a companion as anyone could ever want. Once, after getting into it with a porcupine, he trustfully looked into my eyes as I extracted dozens of barbed quills from his mouth. With pliers. His pain was unbelievable, his trust stronger. Something I’ll never forget.
As much as I like animals, members of my species are more important to me. Given the choice, I’ll sacrifice wildlife for human welfare. Any day. This puts me at odds with many in the environmental movement. It is where we part ways.
Take Switzerland, for example. Residents are no longer allowed to flush sick aquarium fish down the toilet. Unless, that is, they are first euthanized with a “sharp blow to the head, or immersed in water mixed with clove oil dissolved in alcohol.” The country’s animal lawyer, Antoine Goetschel, is suing a sports fisherman who landed a 22 pound pike for taking too long to reel in the fish: cruel behavior, or some such allegation.
This is relevant information.
Before we in the wastewater biz find ourselves on the wrong side of political correctness, we need to work on our terminology. We need to come up with a new way to refer to “wasting sludge.” Sludge, after all, is mostly bacteria – living creatures. Sounds pretty cruel to so casually discuss the death of so many little organisms, don’t you think? Before someone re-labels our work “genocide,” somebody needs to form a committee and give us a new name. Something like “bio-solids recycling.”
I’m suggesting we take the offensive because it will only be a matter of time before Attorney Goetschel and his ilk find out that wastewater professionals use chlorine to KILL filamentous bacteria. If word of this gets out, we’ll be required to establish pre-death chambers with soothing music and nice art work. Or, some such thing.
How about this for a pro-active idea: let’s form a committee to figure out how we perform the proper forensics on aquarium fish that get flushed. I’m thinking we can check them for head blows or traces of clove oil and alcohol. Little fishes that don’t show signs of either can then be delivered to the police for follow-up investigation. Call it our way of stopping animal cruelty.
Okay, I’m kidding. But really!
