Edi (electrodeionization) is an advanced technology for the preparation of pure and superpure water. It scientifically combines electrodialysis technology and ion exchange technology to achieve continuous production of high quality without the use of acids and alkali.
The principle of edi is based on the combination of electrodialysis and ionic interchange. Under the influence of a permanent electrical field, edi carries out the directed migration of ions in water through the selective penetration of cations and anions through cation and anion membranes and the exchange of ions in water with ionosynx resin, thus achieving deep water purification and desalination. During this process, hydrogen ions and hydroxide ions formed as a result of water electrolysis continuously regenerate additional resin, allowing the edi water production process to continuously produce high-quality superpure water without the need to regenerate acid and alkaline chemicals.
The advantages of edi technology include:
Advanced technology: combines the advantages of electrodialysis and ion exchange technology to achieve deep water desalination.
Easy to operate: the system is compact in design and easy to operate, which reduces the number of complex stages of the traditional water treatment process.
Environmental: there is no need to use acid and alkaline, which completely eliminates problems related to acid and alkaline consumption and pollution of liquid chemical waste, ensuring clean production.
Stable wastewater quality: the quality of the water produced is best stable and can be widely used in areas such as electricity, electronics, medicine, chemicals, food and laboratories. It's a green revolution in water treatment technology.
