Ultrapure water Tips: ultrapure water refers to the following low impurity content of water: - EDI ultra-pure water equipment EDI Guangzhou ① inorganic ionized impurity ultra-pure water equipment supply, 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 organic compounds, such as benzene sulfonic acid, oil, organic iron, organic aluminum and other hydrocarbons etc; 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 manufacturers, 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 Guangzhou ultra-pure water equipment procurement, microbes per 1 ml of 0 to 10. Modern use pretreatment, electrodialysis, ultraviolet disinfection, reverse osmosis, ion exchange, ultrafiltration and various membrane filtration technology Guangzhou EDI ultra-pure water equipment, ultra-pure water resistivity reaches 18 (megohms at 25 ℃ · cm). - Preparation of Super Water craft EDI ultra-pure water equipment chemical industry roughly divided into the following categories: - EDI ultra-pure water equipment 1, the use of ion exchange, the process is as follows: Raw water → raw water pressure pump → Multi-media filter → activated carbon filter → → → precision filter water softener cation resin anion resin filter bed → → yin and yang resin filter bed mixed bed → → water points micropore filter 2-stage reverse osmosis methods, the process is as follows: Raw water → raw water plus pump → → Multi-media filter activated carbon filter softener → → → precision filter regulator first stage reverse osmosis → PH → intermediate tank → second stage reverse osmosis (RO membrane surface with positive charge) → purification tank → pure microporous filter pump → → water points 3, using EDI, the process is as follows: Raw water → raw water pressure pump → → Multi-media filter activated carbon filter → → → precision filter water softener reverse osmosis machine → intermediate tank → middle of the pump → EDI system → → water points micropore filter Guangzhou EDI ultra-pure water equipment manufacturers, EDI equipment Guangzhou, Guangzhou Tianshui Tianshui provided by the Environmental Protection Technology Co., Ltd. in Guangzhou.
