nanofiltration membrane

The molecular weight cut-off of nanofiltration membrane is between reverse osmosis membrane and ultrafiltration membrane, about 200-800 daltons. Retention characteristics: Priority is given to the retention of divalent and multivalent anions, and the retention rate of monovalent ions is related to the concentration and composition of the feed solution. Nanofiltration is generally used to remove organic matter and pigments from surface water, hardness from groundwater, and partially remove dissolved salts. It is used for substance extraction and concentration in food and biopharmaceutical production. The operating pressure of nanofiltration membranes is generally 3.5-30 bar.
