ABSTRACT:
Cationic polymers having a molecular weight greater than about 200,000 can be added to the activated sludge in an MBR for industrial wastewater treatment for reasons, which include: conditioning the activated sludge; improving flux through a membrane in the MBR; reducing fouling of the of the membrane in the MBR; and reducing foaming of the activated sludge in the MBR.
