Abstract:
A manufacturing method of alkaline ionized water comprising applying an electrolytic voltage between a cathode electrode and an anode electrode inside an electrolytic bath with continuously supplying an aqueous solution containing an electrolyte to said electrolytic bath, so as to produce alkaline ionized water through electrolysis of said aqueous solution containing an electrolyte, whereinan electrolytic bath having a three-cell configuration having a cathode cell, an intermediate cell and an anode cell, which are separated by a pair of diaphragms, is used, raw material water for production of acidic water is supplied to said anode cell, pure water is fed to said cathode cell, and an electrolysis solution is circulated and supplied to said intermediate cell, so as to produce alkaline ionized water in said cathode cell of said electrolytic bath; an operation, where said alkaline ionized water thus obtained is again supplied to said cathode cell and is subjected to application of electrolytic voltage, is repeated to accumulate a cation; supply of alkaline ionized water produced in said cathode cell to said cathode cell is carried out with a circulation system, in which said alkaline ionized water is withdrawn from said cathode cell and supplied to said cathode cell by a pump, with storing the same in a container equipped outside said electrolytic bath; and said supply of said alkaline ionized water produced in said cathode cell and said application of an electrolytic voltage are repeated until a pH value of said alkaline ionized water reaches pH 12.0.
