Equipment overview.
Mixed bed is the abbreviation for mixed ion exchange column, which is the equipment designed for ion exchange technology. It is a mixture of a certain proportion of cation and anion exchange resins filled in the same exchange unit to exchange and remove the ions from the fluid. As the specific gravity of the cation resin is greater than that of the anion resin, the anion resin is on top and the cation resin is on the bottom in the mixed bed. Generally the ratio of cation to anion resin filling is 1:2, but there are also filling ratios of 1:1.5, which can be selected at the discretion of the different resins. Mixed beds are also divided into in-body synchronous regenerative mixed beds and in-body regenerative mixed beds. The main streams all use synchronous regeneration type mixed bed, in operation and the entire regeneration process are carried out in the mixed bed, regeneration of the resin does not move out of the equipment, and Yang, Yin resin regeneration at the same time, so the need for ancillary equipment less, easy to operate. The mixed bed is mainly used to reduce the hardness, alkalinity and anions and cations in the water, making it softened or deionised water.
Equipment features.
1. excellent water quality, the pH value of the water is close to neutral.
2. stable effluent water quality, a short period of time changes in operating conditions (such as water quality or components, operating flow rate, etc.) on the mixed bed effluent water quality is not significant.
3. intermittent operation has little impact on the effluent quality, and the time required to restore the water quality to that before the shutdown is relatively short.
4. **0% recovery rate is achieved
Application range.
Mixed bed is generally placed after the electrodialysis or reverse osmosis device (or directly applied to water with low salt content), the water can be further desalinated to produce higher purity water, widely used in electronics, chemical, pharmaceutical, atomic energy, electric power and other industries.
