Abstract: THE INVENTION IS DIRECTED TO THE DEIOIZATION OF WATER BY EMPLOYING CATION EXCHANGE RESINS IN THE ALKALINE EARTH FORM SUCH AS CALCIUM AND ANION EXCHANGE RSINS IN THE CARBONATE FORM. THE CALCIUM AND CARBONATE IONS RELEASED FROM THE RESIN DURING THE DEIONIZATION PROCESS PRECIPITATES OUT AS INSOLUBLE CALCIUM CARBONATE TO GIVE AN EFFLUENT FROM THE RESIN EXCHANGER OF POTABLE WATER. REGENERATION OF THE RESINS BACK TO THEIR INITIAL IONIC FORM MAY BE ACCOMPLISHED IN A MIXED BED WITHOUT THE NECESSITY OF SEPARATING THE RESINS. REGENERATION IS PREFORMED BY CONTACTING THE BED WITH A LIME SLURRY, RINSING FREE OF UNABSORBED CALCIUM AND HYDROCIDE IONS AND THEN TREATING WITH CO2. TO CARBONATE THE ANION RESIN. THE RESIN IS THEN READY FOR ANOTHER DEIONIZATION CYCLE.
