Pure water equipment ( Pure water one) mainly uses reverse osmosis membrane technology. Its working principle is to apply a certain pressure to the water, so that the water molecules and ionic mineral elements through the reverse osmosis membrane, and dissolved in the water of the vast majority of inorganic salts (including heavy metals), organic matter, as well as bacteria, viruses, etc. can not pass through the reverse osmosis membrane, so that the infiltration of the pure water and can not be infiltrated through the concentration of the water is strictly separated.
Ultra-pure water equipment also known as high-purity water equipment, is the use of pre-treatment, reverse osmosis technology, mixed bed, EDI devices and post-treatment methods, the conductive medium in the water is almost completely removed, and the water will not dissociate the colloidal substances, gases, and organic matter are removed to a very low degree of water treatment equipment. High-purity water equipment is also known as: ultrapure water, ultrapure water machine, ultrapure water meter, ultrapure water system, laboratory ultrapure water. The water resistivity can reach 18.25 megohm.
