Nanofiltration dessalment nanofiltration

   Nanofiltration is a membrane separation technology similar to reverse osmosis, but the separation layer of nanofiltration membrane is more loose than reverse osmosis. The main function of the nanofiltration membrane is to remove organic matter, microorganisms, viruses and most of the divalent and above metal ions in the water. The removal rate of monovalent ions such as Na+, K+, Cl-, etc. is low, but the hardness, iron , Chroma and THM have high removal rate.

   The nanofiltration membrane separation process does not have any chemical reaction, no heating, no phase transition, will not destroy biological activity, and will not change flavor and aroma. Therefore, it is more and more widely used in the preparation of drinking water and food, medicine, bioengineering, Various separation, concentration and purification processes in industries such as pollution control.
