Abstract: The manufacturing apparatus for producing alkaline ionized water and acidic water by electrolysis of water has an electrolytic bath including a cathode cell, an intermediate cell, and an anode cell, separated by diaphragms; an electrolysis solution bath connected to the intermediate cell via an electrolysis solution circulating line and an electrolysis solution circulating pump; a circulation container bath for alkaline ionized water connected to the cathode cell via an alkaline ionized water circulating line and an alkaline ionized water circulating pump; a supplying line for raw material water for producing acidic water connected to an inlet of the anode cell; a withdrawing line for acidic water connected to an outlet of the anode cell; a supplying system for raw material water for making the alkaline ionized water connected to the circulation container bath and a withdrawing line with a water collecting device for withdrawing alkaline ionized water.

Abstract: A manufacturing method and apparatus of strongly alkaline ionized water exceeding pH 12.0 by electrolysis of water. As an electrolysis solution supplied to a cathode cell of an electrolytic bath, alkaline ionized water produced in the cathode cell is used, and an operation, in which the alkaline ionized water produced in the cathode cell is circulated and supplied to the cathode cell and is subjected to application of electrolytic voltage, is repeated, so that a cation is accumulated to increase the pH value. As a method for circulating and supplying the alkaline ionized water produced in the cathode cell to the cathode cell, a circulation container bath is used, and the circulation container bath and the cathode cell of the electrolytic bath are connected via a circulating line containing a circulating pump. The circulation container bath has a withdrawing system containing a water collecting device for withdrawing alkaline ionized water having a desired pH value to the outside.
