Abstract The treatment of caustic sludge effluent with high COD content and high inorganic salt content utilizes membrane bioreactor. Effluent is treated first biochemically via active sludge and then membrane filtered before discharge directly or to sewage treating yard. The treating process has low clear water consumption and less sludge discharge and thus is low in cost.
