Product Description

RisingSun Membrane NF2 membrane cross refer Suez GE DK series,  2540, 4040 ,8040

NF membranes have a molecular weight cut-off between 150-2000 Dalton usually. RisingSun Membrane manufacture spiral type membrane with sanitary net and glassfiber outer.

Our model NF2, which is high rejection thin-film nanofiltration membrane elements is characterized by an approximate molecular weight cut-off of 150-300 Dalton for uncharged organic molecules. Divalent and multivalent anions are preferentially rejected by the membrane while monovalent ion rejection is dependent upon feed concentration and composition.
