1. Mixed bed
Mixed bed is the abbreviation of mixed ion exchange column, which is an equipment designed for ion exchange technology. The so-called mixed bed is to mix and pack a certain proportion of cation and anion exchange resins in the same exchange device to exchange and remove ions in the fluid. Since the specific gravity of the cation resin is larger than that of the anion resin, the anion resin is above the cation resin in the mixed bed. Compared with the synchronous regeneration type mixed bed, the mixed bed is operated and the whole regeneration process is carried out in the mixed bed, the resin is not moved out of the equipment during regeneration, and the cation and anion resins are regenerated at the same time, so less auxiliary equipment is required and the operation is simple.
2. Ion exchange
Ion exchange is a special solid adsorption process, which is carried out by ion exchange resin in the electrolyte solution. According to the types of ions exchanged, ion exchange resins can be divided into two categories: cation exchange resins and anion exchange resins .
3. Advantages of mixed bed ion exchange system
The mixed-bed ion exchange system adopts the best quality valves, instruments and control systems in the world. The whole process is automatically controlled, which can ensure the stability of the system operation and can realize unattended operation.
