Overview: The ion exchanger process requires the exchange agent to be placed inside the ion exchanger (or bed). The ion exchange capacity is restored by regeneration after the ion exchange agent fails. in order to improve the economy and technical applicability of the ion exchange process, diferent combinations of resins, different bed types and various ion exchange systems have been developed. Common ion exchangers are fixed beds (ion exchangers) and continuous beds.The exchange agent installed in the ion exchanger is in a fixed position during the exchange processsuch an ion exchanger is called a fixed bed, and the exchange treatment of raw water and there generation after resin failure are carried out separately in the same exchanger at different times. Fixedbed ion exchangers can be divided into the single bed, the double bed and the mixed bed according to the type of resin in the exchanger.

A single bed is filled with a single resin; The double bed is filed with strong and weak resins; The mixed bed is filled with Yin and Yang resins. Under normal circumstances the fixed bed refers to the single bed type with fixed bed. Continuous bed ion exchangers are exchangers in which the ion exchange resin operates dynamically and the exchange treatment of raw water and the regeneration after the resin falure are carried out simultaneously in different devices. Use: lon exchangers are mainly used in the preparation of pure water and highly pure water, and havebeen widely used in many industrial fields such as medicine, chemical industry, electronics, paintingbeverage and medium and high pressure boiler water supply. it is used for boilers, thermal power stations, chemical, light industry, textiles, medicine, biology, electronics, atomic energy and pure water treatment, hard water softening reauired for the industrial production , deionized water preparation. it can also be used for decolorization and purification of food and drugs , recovery of precious metals andchemical raw materials, and electroplating wastewater treatment.
