Overview of EDI Ultra Pure Water Equipment (EDI High Purity Water System)

EDI (Electrodeionization) technology, also known as continuous electric desalination process, is a cutting-edge technology in the field of modern high-purity water preparation. This technology cleverly combines electrodialysis with ion exchange technology, utilizing the selective permeation of cations and anions through the membrane, combined with the adsorption function of ion exchange resin, to achieve directional migration of ions under the action of a direct current electric field, thereby completing deep purification of water quality. Its uniqueness lies in the ability to use the H? And OH? Ions generated by electrolysis of water to regenerate the resin layer in real time, enabling the equipment to continuously produce high-purity ultrapure water without the need for acid-base chemical regeneration. This technology has advantages such as advanced technology, modular design, and convenient operation and management. It has been widely used in the fields of power industry, electronic manufacturing, biomedicine, chemical engineering, food processing, and scientific research experiments, and is known as the environmental revolution in the water treatment industry.

　　1、 Working principle of EDI ultrapure water machine

1. The raw water is diverted through the inlet system, with the main water flowing through the internal channels of the resin membrane module and the auxiliary water flowing along the outer surface of the membrane, playing a role in flushing and removing ions;

2. The filled ion exchange resin effectively adsorbs soluble electrolyte ions in water;

3. Under the drive of an electric field, adsorbed anions migrate towards the anode, while cations move towards the cathode;

4. Cations selectively pass through the cation exchange membrane and enter the concentrated water channel;

5. Anions selectively pass through the anion exchange membrane and enter the concentrated water channel;

6. The concentrated ions are discharged from the system along with some of the wastewater;

7. High purity deionized water is continuously produced from the central area of the resin membrane module.

　　2、 Advantages of EDI Ultra Pure Water Machine Products
