THE METHOD OF REGENERATING ION EXCHANGE RESIN PARTICLES HAVING NON-UNIFORM SIZES IN THE RANGE OF ABOUT 60 TO 400 MESH COMPRISING THE STEPS OF MIXING SAID ION EXCHANGE RESIN PARTICLES WITH A REGENERANT SOLUTION TO FORM A MIXTURE, AGITATING SAID MIXTURE TO SUBSTANTIALLY HOMOGENOUSLY DISPERSE SAID ION EXCHANGE MATERIALS IN SAID REGENERANT SOLUTION, SEPARATING SAID RESIN PARTICLES FROM SAID REGENERANT SOLUTION BY PASSING A FILTER SCREEN INTO SAID MIXTURE, APPLYING A PARTIAL VACUUM TO ONE SIDE OF SAID FILTER SCREEN THEREBY CAUSING A PORTION OF SAID MIXTURE TO BE DRAWN TOWARD SAID SOURCE OF PARTIAL VACUUM, SAID FILTER SCREEN PREVENTING THE PASSAGE OF SAID RESIN PARTICLES TO SAID SOURCE OF LOWER PRESSURE WHEREBY SAID RESIN PARTICLES ARE DEPOSITED ON THE OTHER SIDE OF SIAD FILTER SCREEN WHILE PERMITTING THE PASSAGE OF SAID REGENERANT SOLUTION THROUGH SAID FILTER SCREEN, SAID RESIN PARTICLES FORMING A LAYER ON SAID FILTER SCREEN, REMOVING SAID LAYER FROM SAID MIXTURE ON SAID FILTER SCREEN, RINSING SAID RESIN PARTICLES IN SAID LAYER WITH A DEMINERALIZED LIQUID, REMOVING SAID DEMINERALIZED LIQUID FROM SAID RESIN PARTICLES BY APPLYING A PARTIAL VACUUM TO SAID RINSED RESIN PARTICLES IN SAID LAYER ON SAID FILTER SCREEN, REMOVING SAID LAYER FROM SAID FILTER SCREEN AND AGAIN PASSING SAID FILTER SCREEN THROUGH SAID MIXTURE.
