| Abstract: | In this paper improvement of the regenerant of ordinary anion exchange resin was introduced. The strong base type anion exchange resin was treated and transfered to the bicarbonate type. By choosing (MgO CO 2)as regenerant, the regeneration efficiency was greatly increased. According to the experimental results, the optimum concentration of regenerant, the B.T.C?NO - 3 removal efficiency and water output were obtained. |
