摘要
A method of processing backwash water by use of a membrane separation process is disclosed. Specifically, the following steps are taken to process backwash water: collecting backwash water in a receptacle suitable to hold said backwash water; treating said backwash water with one or more water soluble polymers, wherein said water soluble polymers are selected from the group consisting of: amphoteric polymers; cationic polymers, wherein, said charge density is from about 5 mole percent to about 100 mole percent; zwitterionic polymers; and a combination thereof; optionally mixing said water soluble polymers with said backwash water; passing said treated backwash water through a membrane, wherein said membrane is an ultrafiltration membrane or...
