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...
