(author)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,...journal article 2017

(author), Villez, Kris (author), Robin, Orlane (author), de Jonge, Nadieh (author), Rosenthal, Alex (author), Wells, George (author), Nielsen, Jeppe Lund (author), Morgenroth, Eberhard (author), Joss, Adriano (author)The control of nitrite-oxidizing bacteria (NOB) challenges the implementation of partial nitritation and anammox (PN/A) processes under mainstream conditions. The aim of the present study was to understand how operating conditions impact microbial competition and the control of NOB in hybrid PN/A systems, where biofilm and flocs coexist.
