A control system and method for digestion of waste activated sludge ('WAS') includes treating the WAS first at anaerobic conditions for≤ a fixed period of time and then at aerobic conditions for≤a fixed period of time prior to either dewatering or optional anoxic conditions followed by dewatering, supplying air to initiate aerobic conditions when a predetermined set point for maximum ammonium nitrogen has been reached within the fixed anaerobic time, and initiating dewatering or optional anoxic conditions followed by dewatering when a predetermined set point for minimum ammonium nitrogen and optional standards for vector and pathogen reduction are met within the fixed aerobic time, the method and system including monitoring either consumption of soluble alkalinity or orthophosphate reduction or both for maximum orthophosphate reduction within aerobic time.
