Nanofiltration System

Nanofiltration (NF) is a sort of membrane separation technology which is similar to ultrafiltration and reverse osmosis technology. Membrane of nanofiltration system has molecular weight cut off ranging from 200 to 1000 and pore size of only several nanometers.

Although functions similarly to reverse osmosis technology, nanofiltration is generally targeted to remove only divalent and larger ions. Monovalent ions such as sodium and chloride will be allowed to pass through the nanofiltration membrane.

Our nanofiltration system can be mainly used for the desalting and softening of brackish water, the concentration and separation of foods and process stream, reclaimed water and waste water treatment. It can also be applied in chemical processes for concentration and separation purposes. In the field of drinking water treatment, nanofiltration equipment can be applied to remove trihalomethane, odor, undesirable color, pesticides, synthetic detergents, dissolved organic matters, Ca and Mg, and evaporation residues from water.
