Ammonia, oxidation decreases the pH in wastewaters where alkalinity is limited relative to total ,ammonia,. The activity of ,ammonia, oxidizing bacteria (AOB), however, typically decreases with pH and often ceases completely in slightly ,acidic, wastewaters. Nevertheless, nitrification at low pH has been reported in reactors treating human urine, but it has been unclear which organisms are involved ...
