Abstract:
1. A method for electrolyzing a brine solution of water and an alkali salt to produce acidic electrolyzed water and alkaline electrolyzed water, the method comprising: providing a brine solution in a brine bath defined by an internal chamber of a housing; immersing in the brine bath a first electrolyzer cell having a first electrode plate that is connectable to an electrical supply which positively charges the first electrode plate and a cation permeable membrane that is supported relative to the first electrode plate so as to define a first space between the first electrode plate and the cation permeable membrane that is sealed off from the brine bath such that the only path for the brine solution to enter the first space is through the cation permeable membrane; supplying fresh water to an inlet end of the first space between the cation permeable membrane and the first electrode plate; drawing acidic electrolyzed water from an outlet end of the first space; and immersing in the brine bath a second electrolyzer cell having a second electrode plate that is connectable to an electrical supply which positively charges the second electrode plate and an anion permeable membrane that is supported relative to the second electrode plate so as to define a second space between the second electrode plate and the anion permeable membrane that is sealed off from the brine bath such that the only path for the brine solution to enter the second space is through the anion permeable membrane; supplying fresh water to an inlet end of the second space between the anion permeable membrane and the second electrode plate; drawing alkaline electrolyzed water from an outlet end of the second space; and selectively inserting and removing a desired number of the selectively inserting and removing one or more of the electrolyzer cells into and from the brine bath to provide a desired production rate of the acidic electrolyzed water and the alkaline electrolyzed water.
