It set up the development of the world recognized high performance nanofiltration composite membrane of aromatic polyamide, on the basis of reviewing the development, the importance in the membrane separation technology, the classification, the fabrication technique and the current development of the research and the application of the nanofiltration membrane. polysulfone was chosen as the material for making the porous substrate because of its excellent compress - to - denseness resistance, its cheap price and its great availability. by fabricating an ultra thin polyamide functional layer on the polysulfone substrate through interfacial polymerization taking piperazine as the monomer in aqueous phase and trimesoyl chloride as the monomer in organic phase, high performance nanofiltration composite membranes of ultra low pressure and ultra high permeating flux were prepared
