Abstract
A method and a system as described herein, including a method and system of treating ammonium containing water in a deammonification MBBR process where partial nitritation and anaerobic ammonium oxidation may occur simultaneously in a biofilm, or in an integrated fixed film activated sludge process where partial nitritation takes place in a suspended growth fraction and anaerobic ammonium oxidation occurs in a biofilm. The method and system include controlling airflow to the reactor to achieve a target pH, a target alkalinity, a target specific conductivity, and/or a target ammonium concentration in the reactor or in the effluent.
