Product Details
EDI system electrodeionization is a continuous electro-deionization equipment. It actually combines the characteristics of ion exchange resin and ion selective permeable membrane. In other word, it can deeply remove ionic impurities in water and produce high-purity water.
It combines ion exchange with electric drive. Under the traction of electric field force, anions and cations in water migrate to the concentrated water chamber through selective ion exchange membranes respectively, continuously removing almost all ionic impurities in the water. Thereby preparing high-purity ultrapure water efficiently and stably without the need for large amounts of acid and alkali regeneration.
How do EDI system electrodeionization work?
1.Pretreatment
Firstly, pretreatment is the first step in the workflow of EDI system. It’s aim is to remove impurities such as suspended solids, dissolved oxygen, organic matter and bacteria in raw water.
2.Reverse Osmosis (RO) System Treatment
Secondly, the reverse osmosis system uses the selective permeability of the semipermeable membrane to remove dissolved solids, inorganic salts and microorganisms in the water to produce high-purity desalted water.
3.EDI System Electrodeionization Treatment
Thirdly, the EDI system electrodeionizationcombines the principles of electrochemical reaction and ion exchange to achieve deep removal of ions.
4.Subsequent treatment and storage
Finally, to prevent secondary contamination of pure water during storage and distribution, UV ultraviolet sterilizers are usually installed. After the above treatment, pure water enters the water storage tank or pure water tank for storage. And We will distribute pure water to various water use points as needed.
How do EDI system electrodeionization look like?
What are the advantages of EDI system electrodeionization?
1.Technology integration
EDI system combines electrodialysis and ion exchange technology, drives ion migration through electric fields. It uses ion exchange resins for ion removal and regeneration, achieving an efficient and continuous desalination process.
2.Modular design
EDI system usually adopts a modular structure, which is easy to install, debug and maintain. Because of this design, it allows the equipment to be flexibly configured according to actual needs. Thus, meet different treatment scales and water quality requirements.
3.High effluent quality
EDI electrodeionization systems can produce high-quality ultrapure water with stable water quality and resistivity of more than 15MΩ·CM. So,it can meet the high-purity water needs of electronics, medicine, chemical industry, etc.
4.Energy saving and environmental protection
Compared with traditional ion exchange equipment, EDI system does not need to use acid and alkali for resin regeneration. Therefore, it is able to reduce acid and alkali consumption and wastewater discharge, and reduce environmental pollution.
5.Stable operation
Because EDI system is not affected by external conditions such as time, pressure and temperature during operation, and the effluent quality is stable and reliable. There will be no fluctuation or decline in water quality.
