Nanofiltration (NF, Nanofiltration) is a cross between a pressure reverse osmosis and ultrafiltration membrane separation process between the driver, nanofiltration membrane pore size range of about several nanometers. Compared with other pressure-driven membrane separation process occurs later. it can be traced back to the emergence of research JE Cadotte of NS-3 0 0 films in the late 1970s, after nanofiltration developed rapidly, the film is set in the mid-1980s commercialized. nanofiltration mostly from reverse osmosis derived from the membrane, such as CA, CTA membranes, aromatic polyamide composite membranes and sulfonated polyether sulfone film, etc. However, compared with reverse osmosis, its lower operating pressure, and therefore also known as nanofiltration 'low pressure reverse osmosis 'or' loose reverse osmosis (loose RO). nanofiltration desalination rate of 60-90% depending on the choice of different types of uses, nanofiltration and reverse osmosis water production comparing it can retain beneficial minerals in the water as drinking water that is treated economic and health.
