Process and apparatus for the production of electrolyzed water

摘要

Electrolyzed functional water is produced by a two stage electrolysis. There is a first electrolyzing step of continuously feeding water containing electrolyte to an electrolytic cell (1) equipped with an anode (3), a cathode (5) and an ion permeable membrane (7) therebetween to electrolyze it and a second electrolyzing step of subjecting to electrolysis, in the anodic side (9) of an electrolytic cell (2) equipped with an anode (8), a cathode (10) and an ion permeable membrane (12) therebetween, an electrolyte which is electrolyte to be found in the cathodic side (6) of the electrolytic cell (1) of the first electrolyzing step after water fed to said cell has been electrolyzed. Electrolyzed functional water is withdrawn from the anodic side (9) used in the second electrolyzing step after water in this side has taken part in electrolysis in the second electrolying step.
