Abstract
PURPOSE: To draw separate anion exchange resins and draw them out from the tower top while performing regeneration of cation exchange resins by flowing an agueous acid solution from the bottom of the laminated layers of the anion and cation exchange resins in the reguenerating tower and introducing liquid, etc. from the top thereof.
CONSTITUTION: The used mixed ion exchange resins are transferred into a regenerating tower 1 and backwashing water 2 is flowed from its bottom to let the layers of anion exchange resins 3 in the upper layer part, cation exchange resins 4 in the lower layer part and mixed ion exchange resins 5 in the intermediate. An aqueous acid solution 6 of the intermediate density of both exchange resins 3, 4, e.g., an aqueous sulfuric acid solution, is flowed in at the upward flow of velocities of flow of LV0.2m/HW5m/H to regenerate the cation resins 4. At the same time, liquid or gas is flowed in from the top of the tower 1 to let the anion resins 3 float and form an acid solution layer 8 between both resins 3, 4. The anion resins of the upper layer are drawn out through a transfer nozzle 9 and are transferred into the anion regenerating tower.
