Zusammenfassung:	To provide a system for changing a pH of an aqueous environment and a method for operating the system.SOLUTION: A system includes a salt solution feed stream 102 having a first pH and an electrochemical device 130 positioned near the aqueous regeneration area. The electrochemical device is configured to receive the feed stream and convert the feed stream into an acid stream 105 and a base stream 112, each having a predetermined pH value. The first effluent stream includes a base stream and the first effluent stream has a second pH higher than the first pH. The first effluent stream is delivered near the aqueous regeneration area. The second effluent stream includes an acid stream and the second effluent stream has a third pH lower than the second pH.SELECTED DRAWING: Figure 1 【課題】水性環境のｐＨを変更するためのシステム、及びそのシステムを動作させる方法を提供する。【解決手段】システムは、第１のｐＨを有する塩水溶液供給流１０２と、水性再生領域付近に位置付けられた電気化学デバイス１３０と、を含む。電気化学デバイスは、供給流を受け入れ、供給流を、それぞれの所定のｐＨ値を有する酸流１０５及び塩基流１１２に変換するように構成されている。第１の流出流は、塩基流を含み、第１の流出流は、第１のｐＨよりも高い第２のｐＨを有する。第１の流出流は、水性再生領域付近に送達される。第２の流出流は、酸流を含み、第２の流出流は、第２のｐＨよりも低い第３のｐＨを有する。【選択図】図１
