Comment on Sustainable Wastewater Treatment by Terry

Good article, as a manufacturer of biological wastewater treatment plants in Ireland we see this every day. We are developing new methods in our domestic units as well as our commercial & industrial units (up to 5000pe) to retrofit the existing tankages and install our technology into the existing units. Scrubbing the water is one thing, doing it by limiting the carbon footprint and making it sustainable is a much better idea!

Nitrogen is separated from air, by distillation, absorption of diffusion.

Grant; We normally get good nitrification in our process, but tend to have heavy foam/floating sludge on our anoxic zones particluarly in the spring when we tend to get higher I/I and the temps start warming up. We run an 11 day aerobic SRT in the winter with good results and then begin reducing in mid to late March to hit our summer target of 5-6 day SRT. We run a 2Q constant RAS rate. We do not have internal nitrate recycle in our system or foam control (yet). Our wastestream is made up of 50% anerobic digester wastewater from a brewery with the balance made up of septage, residential and other commercial flow. Any suggestions that might help? Thanks.

Jim

Thanks for your insite on the reproduction of bugs.we have quiet a few tours and explaining to young kids why we have to get rid of (waste)bugs that help us out is hard to explain.Another thing that is interesting about them is how they react to tempeture change.It has taken a few warm to cold and cold to warm cycles to relize we go threw a foaming phase.And this is not due to an abundance of fillimants like most people point to.At our plant anyway.Seems that it take alitle time to adjust to the different tempetute then its back to the races or should i say bedroom and they are working day and night the way they should and of course reproducing.

Grant,
you have prety much described what we do here at the city of Groton.One thing i do not understand is that for the longest time we worked at de-tuning our primary treatment and had real good numbers.What we would do is take one of our four primarys out of service.Then while doing maintance we were switching tanks and went back to all four again.And our numbers got even better.Jim and I thought maybe it was do to the increased retention time our nitrate went down.One other thing i notice is that when the nitrate is low we have little or no foam let those nasty nitrate get out of control and you have foam out the you know what.It is a hudge problem in the winter.We also add just a touch of polymer if we see foam becomming a problem that seems to work.Thanks for sending the web site we need more of this kind of stuff.Did you hear i was nominated for Ct director for NEWEA.Thais is the kind of stuff I would like to permote.
Talk soon
Kevin

Hi Grant - There is nothing like being an entrepreneur to make you get up and do something…………even if it is ……..wrong.

You are a scientist, way to go! I worked for CEQ for 1.5 years while I was in DC, way back when.

Cute boat. Does the rest of boat’s name go…”anymore”?
