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, 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, aluminum, and other hydrocarbons and other organic ; EDI ③ particles Guangzhou ultra-pure water equipment purchases, such as dust, iron, aluminum, colloidal silicon; 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. Theoretically EDI ultra-pure water equipment factory in Guangzhou, 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 reverse osmosis equipment EDI ultra-pure water equipment typical process is: 1: Pretreatment - reverse osmosis - Purification water - ion exchange - UV lamp - pure water pump - water point 2: Pretreatment - level anti- penetration - reverse osmosis (positively charged reverse osmosis membrane) - Purification water - pure water pump - UV lamp - water point 3: Pretreatment - reverse osmosis - Middle water - middle of the pump -EDI device - Purification water - pure water pump - UV lamp - Point EDI ultra-pure water equipment water meets: American ASTM standards; electronic unit ultra-pure water quality standards (18MΩ * cm, 15MΩ * cm, 2MΩ * cm and 0.5MΩ * cm four) _ Guangzhou Guangzhou EDI equipment EDI equipment manufacturers _ Guangzhou Tianshui (certified merchants) are provided by the Guangzhou Environmental Protection Technology Co., Ltd.
