Abstract

See full text

A wastewater treatment process that employs anaerobic granular sludge or biomass to remove chemical oxygen demand (COD) from the wastewater. Certain constituents, such as COD, nitrogen, calcium, other dissolved solids, suspended solids, can impair the effectiveness of the granular biomass. Thus, the process employs treatment units to remove these inhibiting constituents to produce a treated effluent or stream. At least a portion of the treated effluent is recycled and mixed with the influent wastewater to reduce the concentration of these inhibiting constituents.
