Reverse osmosis system  

Reverse osmosis(RO) is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules. It is widely used in producing ultra-pure water, pharmaceutics process water, cosmetics, seawater desalination, drinking purified water, distilled water, high pressure boiler water and power station water supply and so on .

Nanofiltration system   

Nanofiltration is a relatively recent membranes filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter. Nanofiltration is also becoming more widely used in food processing applications such as dairy, for simultaneous concentration and partial(monovalent ion) demineralisation.  

Microfiltration System

Microfiltration is a membrane technical filtration process which contaminants from a fluid (liquid & gas) by passage through a microporous membrane pore size rang is 0.1 to 10 micrometers(um). Microfiltration is fundamentally different from reverse osmosis and nanofiltration because those systems use pressure as a means  forcing water to go from low pressure to high pressure. Microfiltration can use a pressurized system but it does not need to include pressure.  

Ultrafiltration system  

The system uses pollution-resistant, hydrophilic PES as its own building material , so it enjoys the advantage of longer lifetime, lighter weight  and compact struture. On top of that , it can withstand high density residual cl-, H202 solution. When it is used in treating bacteria and viruses, the killing rate could reach up to 5log. As a result, the turbidity of water is below 0.01NTU, well above American SWTR standard.
