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; EDI ② organic Guangzhou ultra-pure water equipment, such as benzene sulfonic acid, oil, organic iron, aluminum and other hydrocarbon organic 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 on the provisions of the electronics industry ultrapure water content of 50 to 200 micrograms / liter Guangzhou EDI ultra-pure water equipment manufacturers, and requested a diameter larger than 1 micron particulate matter per 1 ml the content of 1 to 2, per one milliliter of microorganisms from 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 ultra-pure water equipment Guangzhou Tianshui EDI ultra-pure water equipment technology introduced different processes depending on source water quality. Usually after a reverse osmosis water treatment systems, produced water conductivity <10μS / cm, after the reverse osmosis system product water conductivity <5μS / cm or less, after the reverse osmosis system combined with ion exchange equipment or EDI ultra-pure water equipment can be prepared EDI ultra-pure water equipment wholesale Guangzhou, the resistance rate of 18 megohms (conductivity = 1 / resistivity). First, the technical process analysis: 1, RO reverse osmosis + EDI ion exchange system combines mature technology with reliable, easy operation and maintenance; 2, compared with the traditional process with a stable advantage (ion exchange regeneration cycle greatly extended), compared with the latest technology without regeneration, supplies; 3, pre-RO reverse osmosis technology advanced and reliable. EDI and the use of sophisticated technology to make the water tends to be more stable and safe water; Second, the system processes the pretreatment system - reverse osmosis system - intermediate tanks - crude mixed bed - fine mixed bed - pure water - pure water pump - UV disinfection - polishing mixed bed - Ultrafilter - Water target (≥18MΩ.CM) (traditional crafts) - EDI EDI ultra-pure water equipment, ultra-pure water equipment procurement Guangzhou _ EDI ultra-pure water equipment _ Guangzhou Guangzhou Guangzhou Tianshui Tianshui Environmental Technology Limited.
