Reverse osmosis pure water equipment, which uses mainly reverse osmosis membrane technology。It works by applying a certain amount of pressure to water，The water molecules and the mineral elements in the ionic state pass through the reverse osmosis membrane，Most of the inorganic salts dissolved in water (including heavy metals), organic matter, bacteria, viruses, etc., cannot pass through the reverse osmosis membrane，Thus, the permeated pure water and the concentrated water that cannot be permeated are strictly separated;The pore size on the reverse osmosis membrane is only 0.0001 microns, and viruses are usually 0 in diameter.02-0.4 microns, the diameter of ordinary bacteria is 0.4-1微米。The equipment adopts different processes according to different source water quality。General tap water after the primary reverse osmosis system treatment, the water conductivity < 10μS/cm, after the secondary reverse osmosis system, the water conductivity < 2μS/cm or even lower, in the reverse osmosis system supplemented by ion exchange equipment or EDI equipment can be prepared ultra-pure water, so that the resistivity reaches 15-18.More than 2 megohm (conductivity =1/ resistivity)。
