Abstract: THE INVENTION RELATES TO A METHOD FOR CONVERTING STRONGBASE ANION EXCHANGE RESINS FROM THE MONOVALENT ANION FORM TO THE HYDROXIDE FORM. A SOLUTION OF POLYVALENT ANIONS IS FIRST PASSED THROUGH THE RESIN TO DISPLACE THE MONOVALENT ANIONS. A SOLUTION OF ALKALI METAL HYDROXIDE IS THEN PASSED THROUGH THE RESIN TO CONVERT IT TO THE HYDROXIDE FORM, AND TO PRODUCE AN EFFLUENT SOLUTION OF HYDROXIDE IONS AND POLYVALENT ANIONS. THIS EFFLUENT SOLUTION IS THEN NEUTRALIZED WITH AN ACID CONTAINING POLYVALENT ANIONS, AND THE NEUTRALIZED SOLUTION IS PASSED THROUGH A SECOND BATCH OF RESIN IN THE MONOVALENT ANION FORM. IN THE PREFERRED EMBODIMENT, A PORTION OF THE EFFLUENT IS RETAINED WITHOUT NEUTRALIZATION AND IS DELIVERED TO THE SECOND BATCH OF RESIN AFTER THE NEUTRALIZED EFFLUENT TO PERFORM A PORTION OF THE HYDROXIDE REGENERATION.

Abstract: IN THE REGENERATION OF MIXED-BED ION EXCHANGE RESINS, THE RESINS ARE FIRST SEPARATED IN THE CONVENTIONAL MANNER BY AN UPFLOW OF LIQUID. THE RESINS ARE THEN ISOLATED FROM ONE ANOTHER, AND CONTAMINANT CATION EXCHANGE RESIN IS SEPARATED FROM THE ANION EXHANGE RESIN BY FLOATING THE ANION EXCHANGE RESIN IN AN INTERMEDIATE-DENSITY LIQUID HAVING A DENSITY INTERMEDIATE BETWEEN THE CATION AND ANION EXCHANGE RESINS. THE CONTAMINANT CATION EXCHANGE RESIN SINKS TO THE BOTTOM OF THE VESSEL, PERMITTING THE ANION EXCHANGE RESIN TO BE READILY ISOLATED.

Abstract: A METHOD IS PROVIDED FOR THE TREATMENT OF WATER BY ION EXCHANGE WHILE ELIMINATING LEAKAGE. IN CARRYING OUT THE METHOD, WATER IS FIRST PASSED THROUGH A SERVICE LAYER OF ANION AND CATION EXHANGE RESINS IN A SERVICE ZONE IN THE CONVENTIONAL MANNER. SUBSEQUENTLY, THE WATER IS PASSED THROUGH A LEAKAGE BARRIER LAYER OF CATION EXCHANGE RESIN IN THE SERVICE ZONE. PERIODICALLY, THE RESINS IN THE SERVICE ZONE ARE SEPARATED IN A SEPARATION ZONE. THE ANION EXCHANGE RESIN IS THEN REGENERATED IN AN ANION RESIN REGENERATION ZONE, AND THE CATION EXHANGE RESIN IS REGENERATED IN A CATION RESIN REGENERATION ZONE, WHICH PREFERABLY ALSO SERVES AS THE SEPARATION ZONE. A PORTION F THE CATION EXCHANGE RESIN IS THEN TRANSFERRED TO THE SERVICE ZONE TO ESTABLISH A LEAKAGE BARRIER LAYER. THE REMAINDER OF THE CATION EXCHANGE RESIN IS MIXED WITH THE ANION EXCHANGE RESIN, AND THE MIXED RESINS ARE TRANSFERRED TO THE SERVICE ZONE TO ESTABLISH A SERVICE LAYER OF ANION AND CATION EXCHANGE RESINS.

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 densities 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: 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.
