Abstract: THIS INVENTION PROVIDES A METHOD OF REGENERATING ION EXCHANGE RESINS IN A FLUID BED, WHICH CONSISTS IN LOOSENING, ACTUALLY REGENERATING AND THEREAFTER RINSING THE REGENERATED ION EXCHANGE RESINS AS A CONTINUOUS PROCESS IN A SAME AND SINGLE ENCLOSURE, IN SUPERPOSED SUCCESSIVE ZONES THEREOF, BY POSSIBLY VARYING THE UPWARD SPEED OF THE LIQUIDS CIRCULATING IN EACH ONE OF SAID ZONES IN COUNTER-CURRENT RELATIONSHIP TO THE RESIN FLOW, AS A FUNCTION OF THE SPECIFIC ONE OF THE AFORESAID OPERATIONS WHICH IS BEING PERFORMED IN EACH ONE OF THE AFORESAID ZONES. THE INVENTION ALSO COMPRISES, AN APARATUS FOR CARRYING OUT THIS METHOD, WHICH COMPRISES A COLUMN IN WHICH THE SATURATED RESINS CIRCULATE BY GRAVITY FROM TOP TO BOTTOM WITH THE REGENERATING, WASHING AND RINSING LIQUIDS CIRCULATING IN COUNTER-CURRENT RELATIONSHIP TO THE RESINS.
