Nanofiltration is a pressure-driven membrane separation process between reverse osmosis and ultrafiltration, with nanofiltration membranes having pore sizes in the range of a few nanometers. It emerged late compared to other pressure-driven membrane separation processes. Membrane packagers were commercialized in the mid-1980s. Most of the nanofiltration membranes are derived from reverse osmosis membranes, such as CA and CTA membranes, aromatic polyamide composite membranes, and sulfonated polyethersulfone membranes.
