EBPR Selectors

Enhanced Biological Phosphorus Removal (EBPR) is an effective process used in the treatment of wastewater before it is discharged into the environment. EBPR utilizes anaerobic fermentation to maximize the biological uptake of phosphorus by phosphorus-accumulating organisms (PAOs). While the actual uptake of phosphorus occurs in an aerobic environment, PAOs must first be conditioned by exposure to volatile fatty acids (VFAs) in an anaerobic environment. PAOs store food under anaerobic conditions and then process the food once under aerobic conditions.

BioMix-DC Enhanced Anaerobic Mixing optimizes the anaerobic fermentation process by alternating a short mixing cycle with a long deep cycle. This allows stratification in the reactor, increasing the solids retention time in that zone and resulting in the formation of additional VFAs.
