Depending on a variety of raw water quality and user requirements, preparation of highly purified water can be divided into pre-high-purity water treatment, desalination and finishing a three-step process. --EDI High-water equipment 1, pre-treatment includes sand filter, multi-media filtration, softening, chlorine, adjusting pH, activated carbon filtration, degassing. 2, including electrodialysis desalination, reverse osmosis, ion exchange. Electrodialysis principle is the use of cation and anion exchange membranes for ion-selective Guangxi through EDI ultra-pure water equipment supply, desalination rate of more than 95% in the external electric field effect. Reverse osmosis is added to the concentrated solution of pressure on the side of the solvent from the concentrated solution through a semipermeable membrane to dilute the solution side of the reverse osmosis EDI ultra-pure water equipment manufacturers in Guangxi, desalination up to 98%, and can remove 99 percent of bacteria particles and dissolved organic matter in the water. Ion exchange principle is that when water is passed through a cation exchange resin, cation exchange resin is water Guangxi EDI ultra-pure water equipment suppliers cation resin exchangeable cations such as H ions are replaced into the water, and the water and the anion binding the corresponding mineral acid. EDI ultra-pure water equipment Guangxi containing inorganic acids such, when the next step by anion exchange resin layer, water anion is an anion exchange resin. - EDI ultra-pure water equipment 3, the polishing resin exchangeable anions such as OH ions are replaced into the water, combined with water H ions into the water, that ultrapure water polishing includes ultraviolet disinfection, membrane filtration and ultra terminal filter. Industrial water applications and the indicator reference (b): - EDI high-water equipment 4, use: batteries, lithium batteries, zinc-manganese battery production of water indicators: resistivity 5 ~ 10 MΩ.CM reference standard: China's electronic grade water quality technical indicators, GB11446-1-1997 5, use: non-ferrous and precious metals smelting water, nano-production of new materials, aerospace production of new materials, ITO conductive glass manufacturing water, electronic grade process water clean cloth with water Index: resistivity 15 ~ 18.25 MΩ.CM reference standard: China's electronic grade water quality technical indicators, GB11446-1-1997 - EDI high-water equipment US semiconductor industry _ Guangzhou, Guangxi Tianshui _ EDI ultra-pure water equipment supply with pure index Guangxi EDI ultra-pure water equipment provided by the Guangzhou Environmental Protection Technology Co., Ltd.
