ABOUT TNF nanofiltration membranes

MWCO of TNF-60 series composite membrane is about 150-300 Da (neutral organic molecules).The two valence anion and multivalent anions are interception preferred. The retention rate of monovalent ions depends on the concentration and composition.

Monovalent ions through the membrane, does not produce the osmotic pressure. Therefore TNF-60 series membrane system can be a lower than in the reverse osmosis water pressure system operated under pressure.
