Nanofiltration Membrane: Pore size above 1nm, generally 1-2nm. It is a functional semi-permeable membrane that allows solvent molecules or certain low molecular weight solutes or low valence ions to pass through. It is named for its ability to retain substances with a size of approximately nanometers. It is used for removing organic matter and coloration from surface water, removing hardness from groundwater, partially removing dissolved salts, concentrating fruit juices, and separating useful substances from pharmaceuticals.

• ✔Pharmaceuticals (desalination and concentration of antibiotics, vitamins)
• ✔Amino acids (decolorization, removal of impurities, concentration, desalination)
• ✔Food (separation of oligosaccharide, concentration of fruit juice, plant extraction)
• ✔Mother liquor recovery (monosodium glutamate, glucose crystallization decontamination)
• ✔Water treatment (printing and dyeing wastewater, water reuse, ultrapure water)
• ✔Dyestuff (desalination and concentration instead of salt/acid precipitation)
• ✔Acid/Alkali recovery (pharmaceutical washing columns, chemical fiber waste)
