Laboratory-scale sequencing batch reactors (SBRs) operating on an acetate and casamino acids-based synthetic wastewater were used to determine the phosphorus and nitrogen requirements of anaerobic-aerobic (AnA) and completely aerobic (CA) activated sludge. At a 4-day mean cell residence time, AnA activated sludge had an approximately 20% lower phosphorus requirement than CA activated sludge. The difference between the "end-of-aerobic-cycle" polyhydroxyalkanoate (PHA) and carbohydrate contents… CONTINUE READING
