Abstract: The invention relates to a process for internal regeneration of mixed bed filters in which, after the exhausted ion exchanger mass has been separated into the two components and these have been regenerated and washed out, the exchanger layer in the region of the cation exchanger/anion exchanger interface is selectively removed from the mixed bed filter, the cation exchanger remaining in the filter is mixed with the anion exchanger remaining in the filter for the new loading stage, the ion exchanger mass removed from the filter is added again, when the work cycle has ended, to the exhausted ion exchanger mass before or during the separation into cation exchanger and anion exchanger, and, after the separation, the loading stage is started again with the regeneration of the cation exchanger and anion exchanger; and also to a mixed bed filter for carrying out the process.

Abstract: In an ion-exchange separation system, a single regeneration column provides for separation of anion and cation resins and the regeneration of both cation and anion resins with a very low level of cross-contamination. After regeneration most of the anion layer in the column is withdrawn, and most of the cation layer is withdrawn, but a portion of each layer adjacent to the interface between the layers remains in the column, to isolate these cross-contaminated portions from the regenerated resins. The withdrawn, regenerated anion and cation resins are placed back into the working vessel.
