EDI Principle Overview - EDI ultra-pure water equipment continuous electrodeionization (Electro deionization), is the use of mixed ion exchange resin adsorption of ions to the water, while the adsorbed ions and the role of DC voltage, respectively, through the yin and yang ion-exchange membrane process is removed. The process of ion exchange resins is continuously regenerated electrically, there is no need for the use of acid regeneration. This new technology can replace traditional ion exchange unit to produce higher resistivity ultrapure water, usually with the use of EDI and pre-treatment of water and electricity resistance can do 5-15 MΩ.CM reverse osmosis EDI equipment to meet Customer requirements for high water quality. EDI five characteristics: 1, no need to use acid regeneration, without reserve and acid diluted acid transport facilities, safety and reliability, to avoid worker contact with acid; - EDI ultra-pure water equipment 2, saving water and recycling waste water regeneration treatment facilities; 3, reduced operating and maintenance costs; 4, small footprint, simple installation, high water production (95%); 5, continuous operation, product water quality and stability, not because of regeneration downtime. - EDI ultra-pure water equipment, ultra-pure water Tidbits: 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 reverse osmosis EDI equipment maintenance organic content, 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, the principle of reverse osmosis EDI equipment, pure water only H ions and OH ions participate conductive. When ultrapure water at 25 ℃ resistivity of 18.3 (megohm-cm) RO water quality standard EDI device, typically about 15 to 18 (megohm-cm). Determination of organic content of ultrapure water by the organic carbon content, depending on the electronics industry ultrapure water to a predetermined content of 50 to 200 g / liter, and requires a diameter greater than 1 micron per 1 ml substance content of 1 to 2 , microorganisms 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 reverse osmosis equipment maintenance, Maoming reverse osmosis EDI equipment, Guangzhou Tianshui Tianshui manufactured by Guangzhou Environmental Protection Technology Co., Ltd.
