Abstract
PURPOSE: To perfectly separate anion and cation exchange resins for regeneration by feeding a NaOH soln. of a relatively low concn. as a rising stream to the anion exchange resin mixed with the cation exchange resin and by further feeding a NaOH soln. of a density intermediate between those of the resins as a rising stream to discharge the anion exchange resin slurried.
CONSTITUTION: All of anion exchange resin 4 mixed with cation exchange resin K, mixed ion exchange resin 5 and some cation exchange resin 3 separated in separation tower 1 by back washing are conveyed to regeneration tower 6 with water streams. 2W8 wt% NaOH soln. 7 is let to flow into tower 6 from the lower part at a flow rate of LV 0.5W4 m/H to form definite layers of cation exchange resin 3', resin K and resin 4. Next 10W20 wt% NaOH soln. 8 of a density intermediate between those of the resins is let to flow into tower 6 as a rising stream, and water or air 12 is simultaneously fed from the upper part of tower 6 to discharge 10 a slurry of resin 4, thus perfectly separate resin 3' and resin K through liquid layer 9.
