Effects of Anaerobic Selector Hydraulic Retention Time on Biological Foam Control and Enhanced Biological Phosphorus Removal in a Pure‐Oxygen Activated Sludge System
Increased anaerobic selector hydraulic retention times (HRTs) in a high‐purity oxygen activated sludge process resulted in an increase in soluble orthophosphate release and biodegradable chemical oxygen demand removal, confirming that enhanced biological phosphorus removal occurs at aeration solids retention times (SRTs) below 1.7 days. Under operating conditions that included biological foam trapping and recycling, an anaerobic selector with HRTs higher than 55 minutes resulted in a decrease in filament counts and effective foam control. Effective norcardioform control is achieved through the combination of metabolic selective pressure and increased soluble organic substrate removal in the anaerobic selector and low aeration SRT.
