Ultrapure water Tips: ultrapure water refers to the following low impurity content of water: - EDI ultra-pure water equipment ① inorganic ionized impurities, such as Ca, Mg, Na, K, Fe, Fe, Mn, Al, HCO Yin , CO Yin, SO Yi, Cl, NO entertainment, NO Yin, SiO Yin, PO etc; ② organics such as benzene sulfonic acid, oil, organic iron, organic aluminum and other hydrocarbons; ③ particles, such as dust , iron, aluminum, colloidal silica, etc; ③ microorganisms, such as bacteria, plankton and algae; ⑤ dissolved gases, such as N2, O2, CO2, H2S, etc. Resistivity values ??of water content in ultrapure water to measure ionized impurity. In theory, pure water only H ions and OH ions participate conductive. When ultrapure water at 25 ℃ resistivity of 18.3 (megohm-cm), typically about 15 to 18 (megohm-cm). Determination of organic content in ultrapure water from the organic carbon content depending Guangzhou EDI ultra-pure water equipment, electronics industry ultrapure water content of the provisions of 50 to 200 micrograms / liter, and require a diameter larger than 1 micron particulate matter per 1 ml in the amount of 1 to 2 EDI ultra-pure water equipment wholesale Guangzhou, microbes per 1 ml of 0 to 10. Modern use of pretreatment, electrodialysis, ultraviolet disinfection, reverse osmosis, ion exchange, ultrafiltration and various membrane filtration techniques, so that the resistivity of ultra-pure water reached 18 (megohm-cm) at 25 ℃. - EDI EDI ultra-pure water equipment description (a) _____ EDI ultra-pure water equipment (Electro-deionization referred EDI) is an ion-exchange technique, ion-exchange membrane and ion mobility technology (electrodialysis) a combination of pure water manufacturing technology. The technology uses ion exchange capacity desalination depth to overcome the polarization and the electrodialysis desalination is not complete, and water and electricity and the use of electrodialysis polarization occurs from Guangzhou EDI ultra-pure water equipment, H and OH ions produced from renewable realize resin to overcome resin After the failure by chemical regeneration defects, since the 1980s, the gradual rise of new technologies. After ten years of development, EDI technology has been in North America and Europe accounted for a considerable part of ultrapure water market. EDI apparatus belongs polishing water system, and more generally with the reverse osmosis (RO) with the use of the composition of pretreatment, reverse osmosis, EDI ultrapure water treatment system unit, replacing the traditional water treatment process of mixed ion exchange equipment. EDI means the water requirements for the resistivity of 0.025-0.5MΩ · cm, reverse osmosis unit fully meet the requirements. EDI apparatus can produce high resistivity 18MΩ · cm or more ultra-pure water.
