Abstract
【解決手段】カルシウムイオンを含む溶液を両性イオン交換樹脂4に通過させた後、無隔膜電解を行う電解槽5に供給する無隔膜電解の前処理方法。両性イオン交換樹脂によってカルシウムイオンが除去された溶液のカルシウムイオン濃度を200mg/l以下とすることが好ましい。カルシウムイオンを含む溶液から該カルシウムイオンを除去する両性イオン交換樹脂と、該両性イオン交換樹脂によってカルシウムイオンが除去された溶液に対して無隔膜電解を行う電解槽とを備え、該電解槽の処理液を水処理薬剤として用いる水処理システムとすることもできる。水処理システムからの放流水の一部を前記両性イオン交換樹脂に通過させた後、前記電解槽で無隔膜電解を行い、該電解槽の処理液を該水処理システムにおける水処理薬剤として用いることが好ましい。
