EDI ultra-pure water system is a kind of ultra-pure water manufacturing technology that combines ion, ion membrane exchange technology, and electron migration technology. The electrodialysis technology is cleverly combined with ion exchange technology, and the charged ions in water are moved by high pressure at both ends of the electrodes, and the ion exchange resin and selective resin membrane are used to accelerate the removal of the ion movement, so as to achieve the purpose of removing positive and negative ions in water. With advanced technology, EDI pure water equipment with simple operation and excellent environmental characteristics is the green revolution of pure water equipment technology.

EDI Equipment for short, also known as continuous electric desalting technology, will be a scientific integration of electrodialysis technology and ion exchange technology, through the cationic, anionic membrane on the cation, anion through the selection and ion exchange resin on the water ion exchange action, under the action of the electric field to achieve the directional migration of ions in water, so as to achieve the depth of water purification and desalting, and produced by hydroelectricity Hydrogen ion and hydroxide ion can continuously regenerate the filling resin, so EDI water treatment production process can continuously produce high-quality ultra-pure water without the regeneration of acid and alkali chemicals.

Working Process :
EDI water treatment equipment workflow is divided into the following steps:
1. Coarse filtration: Before sending the pump from tap water or other water sources into EDI equipment, it is necessary to carry out coarse filtration to remove large particles of impurities and suspended particles, so as to avoid affecting the treatment effect when entering EDI pure water system.

2. Washing: After the precision filter enters EDI ultra-pure water equipment, it is necessary to wash the precision filter through circulating water to remove impurities and dirt attached to the surface of the filter.

3. Electrodialysis: The ions in water are separated by electrodialysis technology. Specifically, EDI devices use a current applied between two electrodes to drive ions out of the water through the flow of cation and cation ions on the ion membrane. The advantage of electrodialysis is that it does not require the use of chemicals or regenerates and is thus more environmentally friendly.

4. Regeneration: The separated ions are removed in EDI equipment through cleaning and reverse washing, so as to maintain the operating efficiency of the equipment. These ions will be discharged through the wastewater pipe.

5. Removal of purified water: After EDI water treatment, the electrical conductivity of output water will be lower and more pure than before entering the equipment. The water can be put directly into production or stored for later use.
