1、 Basic introduction of mixed bed deionized water equipment:
The mixed bed in the mixed bed deionized water equipment is the abbreviation of mixed ion exchange column, which is designed for ion exchange technology. The so-called mixed bed is to mix a certain proportion of cation and anion exchange resins into the same exchange device to exchange and remove the ions in the fluid. Since the cation resin is larger than the anion resin in the anion bed. Generally, the filling ratio of cation resin and anion resin is 1:2, and there are also those with filling ratio of 1:1.5, which can be selected according to different resins. Mixed bed deionized water equipment mixed bed is also divided into internal synchronous regeneration type mixed bed and external regeneration type mixed bed. The operation and the whole regeneration process of the synchronous regeneration mixed bed are carried out in the mixed bed. During the regeneration, the resin does not move out of the equipment, and the cation and anion resins are regenerated at the same time. Therefore, it needs less auxiliary equipment and is easy to operate.
2、 Advantages of mixed bed deionized water equipment:
The effluent quality of deionized water is close to 1.
2. The effluent quality of the mixed bed deionized water equipment is stable, and the short-term operation conditions (such as influent water quality or components, operation flow rate, etc.) have little impact on the effluent quality of the mixed bed.
3. The intermittent operation of the mixed bed deionized water equipment has little impact on the effluent quality, and the time required to recover to the water quality before shutdown is relatively short.
4. The recovery rate of mixed bed deionized water equipment reaches 100%
3、 Application range of mixed bed deionized water equipment:
The mixed bed is usually placed behind the electrodialysis or reverse osmosis device (or directly applied to water with low salt content). The water can be further desalted to produce high purity water, which is widely used in the industries of electronics, chemical industry, medicine, atomic energy, electric power, etc.
