METHOD OF EVALUATING PERFORMANCE OF ANION EXCHANGE RESIN AND ON-LINE PERFORMANCE EVALUATION APPARATUS

摘要

The present invention relates to a method of managing deionized water purified through an anion exchange resin tower, and more particularly, to a method of evaluating performance of anion exchange resin and an on-line performance evaluation apparatus. A method of evaluating performance of anion exchange resin according to the present invention includes the steps of: measuring in parallel an concentration of positive ions of functional group amino compound, electric conductivity of deionized water, and TOC (Total Organic Carbon); and setting classified indexes of performance of anion exchange resin based on the measured concentration of positive ions of amino compound, electric conductivity of deionized water and TOC. According to the present invention, a degree of deterioration of the anion exchange resin may be directly evaluated by measuring the concentration of the functional group of the eluted anion exchange resin. In addition, as compared with a scheme of managing system water with only electric conductivity, factors of increasing the electric conductivity may be rapidly and exactly grasped by measuring in parallel the concentration of positive ions of functional group amino compound, the electric conductivity of deionized water, and TOC. Further, the performance of the anion exchange resin is monitored through an apparatus for evaluating performance of anion exchange resin through on-line, so that the anion exchange resin may be used at the maximum, thereby evaluating the cost necessary to extend a resin exchange period or drive it. Therefore, system water may be more stably managed.;COPYRIGHT KIPO 2014
