METHOD OF USING WATER SOLUBLE POLYMERS IN A MEMBRANE BIOLOGICAL REACTOR

摘要

A method of conditioning mixed liquor in a membrane biological reactor that includes submerged membrane module (2) within aeration tank (1) comprising adding to the mixed liquor an effective coagulating and flocculating amount of one or more soluble cationic, amphoteric or zwitterionic polymers, or combination thereof and methods of reducing membrane fouling, enhancing membrane flux and reducing sludge production.
