Nanofiltration (NF) Membrane is a pressure-driven membrane filtration process used for low total dissolved solids water such as surface water and fresh groundwater for the purpose of softening and removal of disinfection by-product natural organic and synthetic organic matters. A NF Membrane is located between ultrafiltration and reverse osmosis in terms of its ability to reject molecular or ionic species, and have a nominal pore size of approximately 0.001 microns.
