Nanofiltration Membrane and Its Application
CAO Guo-ping,ZHANG Xue-feng(College of Architectural Engineering,Hebei University of Science and Technology,Tangshan 063009,China)  
The appearance of nanofiltration membrane(NF) in 1980s fills in the gap between reverse osmosis(RO) and ultra-filtration.Normally,the molecular mass cutoff(MWCO) range is 200¡«(1 000,) and its relative pore size is 1¡«(3 nm,) so this membrane is called as NF.NF can retain low relative molecular mass organism and high-valent mineral salt,such as MgSO_4,but to univalent mineral,its rejection is low(10%¡«80%),that is to say,univalent mineral salt can permeate NF freely,which makes the difference of permeation pressure between the two sides of the membrane due to different ion concentration,is much lower than that of RO membrane.In the same flux,NF requires much lower driver pressure than RO membrane.The operation pressure of NF is(0.5¡«)(1.5 MPa.) The particular separating property of NF confirms its status in water softening and low relative molecular mass organism purification and concentration.Furthermore,NF can effectively remove many middle molecular mass solutes,such as the pre-substance of side-products of disinfection,residual pesticide,some pigment.So NF is widely used in water purification and decoloring.
