EDI equipment (Electric ion exchange device) uses RO production water as the inlet water, which can replace the traditional ion exchange device to continuously produce water, ultra-pure water, and the resistivity can reach 10-18 ohm /cm.
EDI device is an EDI unit formed by filling and clamping ion exchange resin between anion/cation exchange membrane.The EDI module separates a certain number of EDI units with a network to form a concentrated water chamber, and sets negative/positive electrodes at both ends of the EDI unit group.Under the promotion of direct current, the water flows into the fresh water chamber, and the anions and cations in the water respectively pass through the anion/cation exchange membrane into the concentrated water chamber and are discharged as concentrated water.
 

EDI technology is a cost revolution in water treatment industry, its biggest characteristic is to use electricity instead of using acid and alkali to regenerate resin, so it is very economical and practical, can have limited energy consumption to obtain stable ultrapure water.It has the advantages of stable effluent quality, low operating cost, convenient operation and management, and small occupation area. Since the industrialization of EDI technology in 1986, it has been widely used in the fields of medicine, electronics, electric power, electroplating and coating.
