Nanofiltration membranes remove particles with a molecular weight cutoff of 200 to 1500. These membranes are ideal for applications requiring the removal of divalent ions, organics, color, bacteria and viruses. Each are ideally suited for integration with either RO or UF membrane products for primary or secondary treatment.
