  • Treatment Of Water By Ion Exchange (AREA)

Abstract

PURPOSE: To reduce the regeneration time of resins and reduce the consumed amount of chemicals by passing the waste water contg. COD components which are made acidic through the serially disposed salt type weak basic anion exchange resins and free base type weak basic anion exchange resins.
CONSTITUTION: The waste water 1' consisting of addition of an acid 2 such as sulfuric acid to the waste water 1 discharged from a waste gas desulfurizer is passed through an ion exchange tower A packed with weak basic anion exchange resin 3 of salt type such as Cl or SO4. Thence, the acidic water 4 after the treatment is passed through an ion exchange tower B packed with weak basic anion exchange resins 3' of free base type, by which the acids in the acidic water 4 are adsorbed to the resins 3' and the neutral treated water 5 is released as it is. Thereby the regeneration processes are simplified, the use of excessive acids and alkalis is obviated and the regeneration time is reduced.
