Abstract: A method for regenerating the exhausted anion and cation exchange resins in a mixed bed demineralizer which utilizes an inert material of a specific density intermediate to the specific densitcies of the anion and cation resins. The inert resin remains in the regeneration system and is not returned to the service vessel with the regenerated resin.

Abstract: An improved method and system that utilizes conductance values of cationic and anionic exchange resins classified as layers of a mixed resin bed to automatically detect interfaces between the layers is disclosed. The arrangement includes electrical circuitry which initially samples the conductivity of a passing resin slurry. The initial conductivity value is compared to subsequent conductivity values of the passing slurry and the flow of the passing slurry is automatically terminated when the subsequent conductivity value is a certain fraction of the initial conductivity value. Termination in response to this equality condition effectively detects the interface between classified layers of a mixed resin bed.

Abstract: A process for scrubbing undissolved impurities from the upper portion of an ion exchange resin filtration bed is disclosed wherein air is introduced in the upper portion of the bed and develops a pressure within the vessel. This pressure subsequently forces rinse water down through the upper portion of the bed and out of the vessel. The gas is introduced into the bed and the water is drained therefrom at a level below the bed's upper surface but above a substantial lower portion of the resin bed. In this manner, lesser quantities of scrubbing fluids are required and the majority of the resin material is left undisturbed to maintain maximum ion exchange capacity.
