The development and application of nanofiltration (NF) membranes is about 20 years later than that of reverse osmosis membranes. In the 1970s, J·E·Cadotte's research on NS-300 membrane was the beginning of research on NF membrane. At that time, Israel Desalination Company used "hybrid filtration" to represent the membrane separation process between reverse osmosis and ultrafiltration, called loose RO membrane. Later, Filmtec Company in the United States called this membrane technology nanofiltration, which has been used until now. After that, nanofiltration technology developed rapidly, and membrane modules were commercialized in the mid-1980s. At present, nanofiltration technology has become one of the research hotspots in the field of membrane separation in the world.
NF(Nanofiltration)series membrane a kind of functional semipermeable membranes that could retention low molecular wight solute and low valence. It design for removing various organics. Microbes, viruses and most divalent or polyvalent metallic ions while retaining part of the sodium, potassium, calcium and magnesium ions.Applied in the production of drinking water and in separation and concentration processes for foodstuff, medicine etc.
