Reverse osmosis is a reverse migration movement of osmosis is a pressure driven .with the help of semi-permeable membrane selective interception effect of the solution solute and solvent seperation method .it has been widely uesd in a variety of liquid purification and concentration ,the most common application example is in the water treatment process,the use of reverse osmosis technology in the raw water inorganic ions ,bacteria,viruses,organic matter and colloids and other impurities to obtain high-quality pure water .According to different use scenarios ,it can be divided into low -pressure reverse osmosis membrane ,ultra-low pressure reverse osmosis membrane and seawater desalination membrane.
Nanofiltration membrane elements are suitable for hardness softening, color purification and other advanced treatment of municipal water with surface water and most well water as water sources. It is suitable for variousapplications such as the manufacture of various industrial water, drinking water, and liquid concentration andseparation.
