Process principle of EDI ultra purified water equipment
Date: 2025-03-18Read: 5
The process principle of EDI ultra purified water equipment is to combine electrodialysis technology with ion exchange technology, utilizing the electric field effect and the selective permeability of ion exchange membranes to achieve deep purification and desalination of water. The specific process is as follows:
1. Electrodialysis process: Raw water is subjected to the action of an electric field, causing cations and anions to move towards the positive and negative electrodes respectively, thereby achieving preliminary removal of ions from water.
2. Ion exchange process: After electrodialysis, water enters the ion exchange membrane and is further removed of ions through the action of ion exchange resin, improving the purity of water.
3. Electric regeneration process: Under the action of an electric field, water molecules electrolyze to produce hydrogen ions and hydroxide ions, which continuously regenerate the ion exchange resin to maintain its optimal state.
