Research progress of nanofiltration pretreatment in reverse osmosis desalination

Reverse osmosis (RO) Seawater desalination is an effective technology for obtaining fresh water, however, such problems as scaling, concentrated water treatment and energy consumption constrain the further development of reverse osmosis. 

By use of nanofiltration (NF) membrane as a reverse osmosis desalination pretreatment process can effectively solve the problem of reverse osmosis membrane fouling, and reduce energy consumption, help to deal with the discharge of concentrated water.
