Description
SiO2⇔Si(OH)4⇔Si(OH)3O-
上記のような平衡状態において各イオン種が全体に占める割合は、pHによって大きく変化する。pHが低い領域では炭酸やシリカの大部分はイオン化していない、つまり電荷を持たない状態でCO2、SiO2として存在している。
以下、図面を参照して、本発明の電気式脱イオン水製造装置の実施形態の一例について説明する。
本発明の効果を確認すべく、次のような比較試験を行った。すなわち、図1に示す第2小脱塩室D-2におけるバイポーラ膜の有無または配置個所が異なる4つの脱イオン水製造装置を用意した。
・陰極室:寸法100×300×4mm AER充填
・陽極室:寸法100×300×4mm CER充填
・第1小脱塩室:寸法100×300×8mm AER充填
・第2小脱塩室:寸法100×300×8mm AER/CER充填(積層)
・濃縮室:寸法100×300×4mm AER充填
・脱塩室流量:50L/h
・濃縮室流量:5L/h
・電極室流量:10L/h
・電極室、脱塩室、濃縮室供給水:二段RO透過水5±1μS/cm
・印加電流値:3A
以上の条件の下で実施例1および比較例1〜3に係る脱イオン水製造装置をそれぞれ200時間連続運転し、運転開始時と運転開始から200時間後の運転電圧、処理水の水質および処理水中のシリカ濃度を測定した。測定結果を表1に示す。
以下、図面を参照して、本発明の電気式脱イオン水製造装置の実施形態の他例について説明する。もっとも、本実施形態に係る脱イオン水製造装置は、陰極室と陽極室との間に複数の脱塩処理部が設けられている点を除いて、実施形態1に係る脱イオン水製造装置と共通の構成を有する。そこで、実施形態1に係る脱イオン水製造装置と異なる構成についてのみ以下に説明し、共通する構成についての説明は適宜省略する。
(実施形態3)
次に、図5を参照して本発明の脱イオン水製造装置の実施形態の他例について説明する。もっとも、本実施形態に係る脱イオン水製造装置の基本構成は、実施形態2に係る脱イオン水製造装置と共通である。そこで、実施形態2に係る脱イオン水製造装置との相違点についてのみ以下に説明し、共通点についての説明は省略する。
