Electrodeionization EDI Systems

What is EDI and How does it work?

 EDI is Electrodeionization (Electrodeionization), which is a kind of water treatment technology combining electrodialysis and ion exchange technology. When working, under the action of DC electric field, cations and anions migrate to positive and negative poles respectively, and enter the concentrated water chamber through ion exchange membrane, and the ions in the fresh water chamber are reduced to become pure water. At the same time, hydrogen ions and hydroxide ions generated by water electrolysis continuously regenerate the ion exchange resin to keep it in the best condition, thus realizing efficient water production.

Reverse osmosis pretreatment: building a solid foundation for water quality

 In the EDI water supply system, reverse osmosis equipment plays an important pretreatment role. Reverse osmosis membrane pore size is very small, can effectively intercept most of the dissolved salts, colloids, microorganisms and other impurities in water. Raw water after reverse osmosis treatment, most of the ions, organics, etc. are removed, significantly reduce the conductivity of water and impurity content, for the subsequent EDI treatment to provide high-quality water, reduce the burden of EDI module processing, is the key first step to improve water quality.

EDI deep purification: realizing high purity water quality

 EDI water supply system further deep purification on the basis of reverse osmosis. It utilizes the synergistic action of electric fields and ion exchange resins to remove residual trace ions in the water, enabling the water quality to achieve higher purity. Compared with reverse osmosis, EDI does not require chemical regeneration, and can continuously and stably produce high-purity water to meet the nearly demanding water quality requirements of the electronics, pharmaceutical and other industries.

Complementary Advantages: Enhancing System Efficiency

 Reverse osmosis and EDI have complementary advantages. Reverse osmosis processing capacity, low cost, can quickly remove most of the impurities; EDI focuses on the depth of desalination, the output water quality is better. The combination of the two ensures processing efficiency and improves water quality standards.
