Product Description

High Rejection NF Industrial Membrane Elements analog DK-series

Our model NF5, 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.
