Water filter for Commercial /industrial,nanofiltration membrane,water purification systems

Nano filtration NF membrane Separation mechanism

NF membrane,as a new separation technology,in the process of separation have two significant features:First,NF membrane separation layer,which consists of polyelectrolyte,under the electrostatic interaction of ion, can separate arange of inorganic substances from solution in a liquid;Second,NF takes in the upper end of reverse osmosis,and thelower end of ultrafiltration,covering MWCO values of 200 to 2000 Daltons.NF membrane surface aperture at the nanoscale,and the smallest molecular which the rejection rates can reach above 90% is about lnm,so which is called nanofiltration.
