Working principle and application advantages of EDI purified water equipment
Date: 2025-09-03Read: 4
EDI purified water equipment is an efficient water treatment system that combines electrodialysis and ion exchange technology. Its core principles and application advantages are as follows:
1、 Working principle
1. Ionic adsorption and migration
The device is filled with mixed ion exchange resin to adsorb anions and cations in water. Under the action of a direct current electric field, cations move towards the cathode and pass through the cation exchange membrane, anions move towards the anode and pass through the anion exchange membrane, and ultimately impurity ions are isolated and discharged from the concentrated water chamber.
2. Resin automatic regeneration
The hydrogen ions and hydroxide ions generated by water ionization can automatically regenerate the resin without stopping the machine for acid-base chemical regeneration, achieving continuous water production.
3. Component synergy
Freshwater chamber: preliminary desalination;
Ion exchange membrane: selective permeation of specific charged ions;
Concentrated water chamber: Collect and discharge concentrated impurities.
2、 Application advantages
1. Environmentally friendly and efficient: reducing acid and alkali consumption by over 95%, without chemical pollution;
2. Stable water quality: The resistivity reaches 15-18 megaohms per centimeter, meeting the needs of industries such as electronics and pharmaceuticals;
3. Automated operation: Modular design supports 24-hour uninterrupted water production, with low maintenance costs;
4. Widely applicable: covering high-precision fields such as semiconductors, medical injection water, laboratory analysis, etc.
This technology achieves efficient and environmentally friendly pure water preparation through the synergistic effect of electrochemistry and ion exchange.
