Introduction to Nanofiltration Membrane

Nanofiltration membrane is a separation membrane with molecular precision, and its molecular weight cut-off is about 200-2000, which is between reverse osmosis membrane and ultrafiltration membrane. Most nanofiltration membranes are composite membranes, and the outer separation layer is composed of polyelectrolyte, so it has a certain rejection rate to inorganic salts.

The removal efficiency of nanofiltration membrane on soluble monovalent ions is lower than that of high-priced ions. Nanofiltration membrane is generally used to remove organic matter and pigment in surface water, and partially remove dissolved salts. It is used in the extraction and concentration of useful substances in food and pharmaceutical production. The operating pressure of nanofiltration membrane is generally 3.5-30bar.
