Description

【００２３】
【実施例】
次に、実施例を挙げて本発明を更に具体的に説明するが、これは単に例示であって、本発明を制限するものではない。
実施例１
下記装置仕様及び運転条件下において、図１に示す構成で３個の脱イオンモジュール（６個の小脱塩室）を並設して構成される電気式脱イオン水製造装置の脱塩室及び濃縮室にそれぞれ通水して、５００時間の通水運転を行った。評価は５００時間の通水運転における平均電圧、平均電流及び運転終了時の第１脱塩室の通水差圧及び処理水質で行い、結果を表１に示す。なお、使用したアニオン交換樹脂はIRA-402BL 、カチオン交換樹脂はIR-124( それぞれローム& ハース社製)である。

【Example】
Next, the present invention will be described more specifically with reference to examples, but this is merely an example and does not limit the present invention.
Example 1
Under the following apparatus specifications and operating conditions, the desalination chamber of the electric deionized water production apparatus configured by juxtaposing three deionization modules (six small desalination chambers) with the configuration shown in FIG. Water was passed through each of the concentration chambers, and a water passing operation was performed for 500 hours. The evaluation was performed based on the average voltage and average current in the 500-hour water-flow operation, the pressure difference in water flow in the first desalination chamber at the end of the operation, and the quality of the treated water. The results are shown in Table 1. Incidentally, annealing ion-exchange resin used was IRA-402BL, cation-exchange resins are IR-124 (manufactured by respectively Rohm & Haas).
