Introduction to Nanofiltration Membrane
Nanofiltration (NF) membrane is a type of pressure – driven membrane filtration technology that lies between ultrafiltration and reverse osmosis. Nanofiltration membranes have pore sizes typically in the range of 1 – 10 nanometers. They are capable of selectively rejecting certain solutes based on their size, charge, and chemical properties.
