Abstract
PURPOSE: To improve the washing rate of resin and reduce the washing time in iron removing process of cation exchange resin, by adding a small quantity of acid and mixing the resin layer after replacing the iron removing agent in the resin layer with extrusion water.
CONSTITUTION: Hydrogensulfite component and sulfurous acid component are made to coexist in a liquid and the liquid is adjusted to ≥5.5pH, and cation exchange resin is treated with an iron removing agent. When washing after this, the iron removing agent in the resin layer is replaced with extrusion water. The resin layer is mixed while adding a small quantity of iron or immediately after addition of iron, and washed with washing water. In this way, washing can be made effectively and washing time can be reduced remarkably.
