Usually, most people would think that the primary pure water equipment for purifying raw water (tap water, well water), but in pure water, also known as the purification of high purity water, but in the capital on the freshwater changes gradually decreasing, the earth facing the pressure, we have no parallel in history. In order to meet the needs of people on the earth's water capital? How can we expand the water capital? In the constant research and exploration, in the middle of the study, can not rely on the conditions of the outside world to meet the needs of water, dilute the capital?
Scientific research and research show that: in addition to the pharmaceutical, food, industrial, electronic fields of the application of a wide range of accidents, completely able to use pure water equipment for desalination. The main center of water equipment is the reverse osmosis membrane method, the first choice is desalination and purification, this method is not only the solvent through a semipermeable membrane through separation of solutes in seawater and freshwater, seawater at low pressure if the external pressure, the penetration of the historian enrichment in seawater, the pure water into fresh water through a semipermeable membrane.
Therefore, the choice of membrane permeability of pure water equipment is the so-called reverse osmosis desalination team to dilute the capital, thereby accurately changing the surface of the water on the ground. However, to continue to study and explore the reverse osmosis membrane, the ability to dilute the reverse osmosis membrane function has made greater progress. Membrane material is a new type of material and high efficiency film, which is developed from the previous monolayer of cellulose acetate to the surface polymerization of the crosslinked aromatic polyamide composite membrane.
