Product Introduction:

The molecular weight cutoff of nanofiltration membrane is between that of reverse osmosis membrane and ultrafiltration membrane, about 200-800 Daltons. Retention characteristics: preferential retention of divalent and polyvalent anions, and the retention rate of monovalent ions is related to the concentration and composition of the feed liquid. Nanofiltration is generally used to remove organic matter and pigments in surface water, hardness in groundwater and partially remove dissolved salts, and is used for the extraction and concentration of substances in food and biopharmaceutical production. The operating pressure of nanofiltration membrane is generally 3.5-30bar.

We provide a variety of fine molecular weight cutoff roll nanofiltration membrane elements with compact structure and reasonable surface area/volume ratio. By using different flow channel networks (13-120mil), the width of the feed liquid flow channel can be changed to adapt to feed liquids of various viscosities. In order to meet the application of some special industries, we can select suitable nanofiltration membranes for customers according to customer process requirements, different treatment systems and related technical requirements.
