чистой воды машины-электро деионизации оборудование для

pure water machinery-electro deionization equipment EDI(Electrodeionization) technology scientificallycombine electrodialysis with ion exchang technology and substitutes the traditional ion exchang bed technique.The advantages are:1.Continuous production,no need for acid and alkali regenerating, without the emission of acid and alkali solution2.Stable quality of output water3.Low woking cost,standard design4.Compact structure5 Convenient operation and managementApplication Field:Product range can be used in to the semiconductoe industry, the electronic industry, the power plant, the chemcial industry, the petroleum industry, the metallurgy industry, the pharmaceutical indusry, the food and beverage industry, the pilp&paper industry, the automatic industry and many other industries.Operating Feed Water Specifications:SpecificationNotesWorking RangeOptimum PerformanceFeedwater SourceRo water,direct feed, or with intermediate break tank plus filterEDI Feed ConductivityIonic load determines size of the working bed and polishing bed within the EDI1-20 us/cm1-6 us/cmFeedwater Conductivity Equivalentless than 50us/cmless than 10us/cmPHLow ph feedwater typically indicatrs the presence of CO2 which will decrease quality5.0-9.57.0-7.5Total CO2Combined CO2 and HCO3-less than 5mg/lless than 2mg/lTemperature5°C to 40°C20°C to 30°CHardnessCa2+ and Mg2+ as CaCO3less than 1.0ppm at 90% recoveryOrganicsTOCless than 0.5ppmNot DetectableMetalsFe,Mn,transition metalsless than 10 ppbNot DetectableSilica,SiO2Typically dissolved, reactiveless than 0.5ppmless than 0.2ppmOxidizersCl2 and O3 typicallyNot DetectableNot DetectableParticlesRecommended direct feed partical-free RO permeate, or 1um pre-filtration of feed from intermediate tankSDI less than 1SDI less than 0.5 Product Water Qualoty of the Module: Resistivity: 16 18MΩ·cm Silica: 5 20ppb PH: 7.0±0.2
