Abstract
In a method of regenerating mixed ion exchange materials, the materials are classified into layers. The lower layer is then transferred from the separator vessel. The transfer is controlled by detecting an interface between materials. The separated materials are then regenerated after which the anion material is reclassified to allow any contaminant cation material to settle to the bottom thereof. Material is then removed from the bottom of the anion layer to remove settled contaminant cation material. The removed material is isolated from the regenerated materials which are then remixed. The method reduces the cross-contamination of materials that occurs during the separation of classified materials and, particularly, reduces the amount of cation material in the sodium form (following regeneration of the anion material) that is eventually returned to service.
