Abstract
An electrolytic ionized water (EIW) producing apparatus comprises an anode, a cathode, an electrolyzer which includes an anode chamber, a cathode chamber and an intermediate chamber, inlet lines for supplying an influent water to the three chambers, and outlet lines for discharging effluent water from the chambers. Further, an acidic electrolyte supplying unit is connected to the outlet line from the anode chamber, and an alkaline electrolyte supplying unit is connected to the outlet line from the cathode chamber. The electrolyte supplying units can selectively control at least the dosage level of elelctrolyte(s) to be supplied, the composition and concentration of the electrolyte(s) or pH of EIW after the addition of the electrolyte(s).
