WebMixed bed ion exchangers have resins for both cation and anion exchange within the same column. The denser cationic and lighter anionic resins are mixed together by compressed air during loading, but separated during regeneration and backwashing. Regeneration is sequential; alkali solution is used for the anions, and acid is used for cations. http://www.dardel.info/IX/processes/regeneration.html

Web12 aug. 2024 · Ion regeneration is the removal of the ions that block or plug the internal exchange sites on resins; it includes the following three main steps: backwashing, regeneration and rinsing. The regeneration process is capable of restoring only 60–80% of the resin capacity, as some ions and hardness are retained on the resins. WebION EXCHANGE PROCESS Ion exchange treatment is the exchange of ions between the aqueous solution and the ion exchange’s fixed-charge counter ion. Ion exchange resin has a total capacity and an operating capacity, which are dependent on the following factors: Type of resin and total number of functional sites per unit of volume.
