As Houston experiences multiple days above 100 deg F, I am checking in with customers that have problems with high temperatures in their wastewater treatment plants during summer months. Most wastewater plants were designed to operate in a mesophilic temperature range between 10 - 38 deg. C. If you fall below or above this range, the biological processes exhibit stress. Today I want to talk about the changes we see as you go from a comfortable (to bacteria) 30 up to 40+ deg C.
At 30 Dec C, most of our common wastewater mesophilic microbes are in near ideal conditions and growth rates are also near maximum. The amount of biomass and associated biopolymers make for excellent floc formation with little foaming on the aeration basin. Additionally, the effluent TSS, BOD, and tubidity are typically excellent.
Once you hit 38 Deg C,
