| Zusammenfassung: | To provide a water treatment apparatus capable of reducing an amount of chemical additive.SOLUTION: A water treatment apparatus includes a calcination apparatus, a first conditioning part, a water softening apparatus, a second conditioning part, and a reverse osmosis membrane apparatus. The calcination apparatus removes dissolved carbon dioxide components from the water to be treated. The first adjustment part adjusts the treated water from which the dissolved carbonic acid components have been removed to near neutral. The softening part softens the above-neutralized water to be treated. The second conditioning part adjusts the softened water to alkalinity. The reverse osmosis membrane apparatus separates the alkaline-adjusted treated water into concentrated water and permeated water by a reverse osmosis membrane.SELECTED DRAWING: Figure 1
【課題】 薬液の添加量を削減可能な水処理装置を提供する。【解決手段】 水処理装置は、脱炭酸装置、第１調整部、軟水化装置、第２調整部、及び逆浸透膜装置を備える。脱炭酸装置は、被処理水中の溶解炭酸成分を除去する。第１調整部は、前記溶解炭酸成分が除去された被処理水を略中性に調整する。軟水化装置は、前記略中性に調整された被処理水を軟水化する。第２調整部は、前記軟水化された被処理水をアルカリ性に調整する。逆浸透膜装置は、前記アルカリ性に調整された被処理水を、逆浸透膜により濃縮水と透過水とに分離する。【選択図】図１ |
