Abstract
PURPOSE: To prevent the pressure densification of weak ion exchange resin by installing a distributor system introducing liquid or gas at the boundary surface of an upper layer portion of weak ion exchange resin and a lower lager portion of strong ion exchange resin filled in ion exchange column.
CONSTITUTION: Weak ion exchange resin A and strong ion exchange resin B is respectively filled in an upper and lower layer portion within ion exchange column and a solution to be treated is supplied from the tube 11, 13 and discharged through the liquid collecting system 18 and tube 20 to the outside of column 1. In regenerating process, air is introduced from the tube 12, 13 and the water in the upper portion of resin layer A is removed through the liquid collecting system 14 and tube 15 to drop the water level to 5W20cm above the top surface of resin layer A. Thereafter air is introduced from the distributor system installed at the boundary surface of resin layer A and B and exhausted from the tube 13, 11 to break the blocked lump of resin layer A by bubbling, thereafter the broken resin is exhausted to the outside of the column 1 through the tube 13, 12 by introducing liquid from the system 16 and suspended substance in water formed by bubbling is removed before a regenerating reagent is introduced.
