Evaluation of Application of Nonofiltration Technology in Reverse-Osmosis Sea Water Desalination Pre treatment

Having considered the general situation of application of nanofiltration (NF) technology in China and outside China in the field of water treatment,the technical advantages of nanofiltration technology for reverse osmosis sea water desalination pre treatment are analyzed.China is still in an initial stage in NF application and needs to strengthen its study on anti organic pollution and anti microbiological pollution membranes and to set up model projects in order to promote the development of NF technology.
