TORAY membrane TMH20A-430

　　The key problems of reverse osmosis facilities manufacturing pure water: one is the selective membrane, we call it semi-permeable membrane, the other is the certain pressure. Put simply, there are a large number of pores on the reverse osmosis semi-permeable membrane, the size of these pores is almost same to that of water molecules, because the size of bacteria, viruses, the majority of organic pollutants and hydrated ion is greatly bigger than water molecules, they cannot be separated from the water permeated reverse osmosis membrane. In the many kinds of impurities of water, dissolved salt is the most difficult to remove. Therefore, the purification efficiency is up to the high or low salt removal, and the salt removal efficiency is up to the selectivity of reverse osmosis semi-permeable membrane. At present, salt removal of the higher selective reverse osmosis membrane component can reach more than 99.7%.

　　Reverse osmosis technology the most advanced, energy-saving and efficient separation technology. The principle is that the pressure higher solution osmotic pressure, by the aid of the selective interception of reverse osmosis membrane which only allows water molecules to permeate, separate the solvent and solute in the solution which will reach the purpose of water purification.

　　Reverse osmosis membrane is composed of polymerization cellulose with high ordered matrix structure. Its core diameter is 0.1nm-1nm, that is to say one ten billionth m(the one thousandth of colon bacillus, one hundredth of virus )
