Title:
陰イオン交換樹脂の性能評価方法、純水の製造方法及び水処理システム
Document Type and Number:
Japanese Patent JP7179641
Kind Code:
B2
Abstract:
To provide a method for evaluating a performance of an anion exchange resin, a method for producing purified water, and a water treatment system capable of performing evaluation and degradation diagnosis of an anion exchange resin in consideration of its reaction rate to be performed more appropriately.SOLUTION: A method for evaluating a performance of an anion exchange resin includes accommodation of an anion exchange resin in a microcolumn with a controllable permeation line rate, passing a silicic acid-containing solution through the microcolumn accommodating the anion exchange resin, measuring the silicic acid concentration and/or silic acid removal rate in the effluent from the microcolumn, and evaluating the performance of the anion exchange resin based on the results of measurements of the silic acid concentration and/or silic acid removal rate.SELECTED DRAWING: Figure 1
