Abstract: A wastewater treatment process uses enhanced primary treatment to remove suspended solids from raw wastewater. Primary sludge is treated in a fermenter. Primary effluent is treated by biological nutrient removal (BNR) to produce a treated effluent and waste activated sludge (WAS). The WAS is treated in an anaerobic digester, which also treats sludge from the fermenter. Anaerobic digestate is separated to provide a liquid effluent. The liquid effluent is stripped of phosphorous and returned to the BNR as a source of readily biodegradable carbon. Liquid in the fermenter may also be separated to provide a liquid rich in volatile fatty acids (VFAs). This liquid is returned to the BNR when additional VFAs are required.
