Nano filtration membrane is a special and Functional semi-permeable membrane which Selectively allows certain LMW and low-valentlon to pass through .its desalination rate is Between 40-98%.lt can block the organic in the Range of 150-500 LMW, and it performs better In desalinating single valence anions solution. Now days, Nano membranes have been widely Used in many fields, including drinking water, Food processing, pharmaceuticals and biology Industry.
