EDI纯水设备系统，作为前沿的净水技术，它不仅继承了混合离子交换技术的精髓，还融合了反渗透（RO）的先进性，打造了一种更加高效、环保且经济的纯水生产方式。与传统的MB-DI相比，EDI纯水设备在稳定性、自动化控制、运行成本和空间占用等方面都有显著提升。它能够提供极低的电导率，从而满足工业生产对高纯度水的严格要求。
ED pure water device system, as the cutting-edge technology in water purification, not only inherits the essence of mixed bed ion exchange technology but also integrates the advancedness of reverse osmosis (RO), creating a more efficient, eco-friendly and cost-effective method for producing high-purity water. Compared with traditional MB-DI systems, EDI pure water devices excel in stability, automation control, operating costs and space occupancy.
The development history of high-purity water equipment can be divided into three stages: pre-treatment → cation exchange bed → anion exchange bed; pre-treatment → reverse osmosis → cation exchange bed; and pre-treatment → reverse osmosis → EDI device. The latter stage has become a new standard for industrial-scale purified water production due to its superior performance over previous technologies.
The working principle of EDI pure water devices is based on ion exchange resins and selective ion membranes. Water enters the system through both internal resin/membrane pathways and external flow channels for washing away ions outside the membrane. Resin captures dissolved ions from feedwater while electrodes drive ions towards their respective poles through membranes to produce clean output without chemicals or waste disposal concerns.
For optimal results when using an ED pure water device system, input feedwater must meet specific criteria: Total Organic Carbon (TOC) <0.5 mg/L, Silica <0.5 mg/L CO2 <25 mg/L as CaCO3 pH 5-9 Hardness <0.1 mg/L as CaCO3 Fe,Mn,H2S<0.01mg/L Pressure range: 30-100 PSI
In summary, EDI pure water devices represent a quantum leap forward in industrial-scale purified drinking-water production by combining RO filtration with electrical regeneration techniques that eliminate chemical usage altogether—thus meeting modern industry's stringent demands on purity levels while minimizing environmental impact effectively!
