Abstract

PROBLEM TO BE SOLVED: To eliminate the shortening of electrode life caused by the precipitation of calcium carbonate simultaneously with the removal of harmful anions by arranging activated carbon, an anion removing means and a porous hollow yarn membrane to the raw water supply pipe of an electrolytic tank electrolyzing raw water to make acidic water and alkaline water. SOLUTION: Tap water being raw water is allowed to flow through granular activated carbon at first to remove free residual chlorine or a musty smell component in water and this water is succeedingly allowed to flow through a porous hollow yarn membrane to remove pollutants in water. Next, the tap water is allowed to flow through an anion exchange resin being a anion removing means and a harmful anion component comprising nitrate ions or the like in water is removed. Thereafter, tap water is allowed to flow through an electrolytic cell and electrolyzed by allowing a current to flow across an anode and a cathode to form acidic water and alkaline water. By this constitution, not only nitrate nitrogen but also a carbonic acid component present in tap water are removed not only to form water suitable as drinking water but also to extend the life of the electrodes of the electrolytic cell.

After passing 50 L of water, the electrolytic cell was opened and the electrode surface was observed. As shown in FIG. 5 (b), a very large amount of dark white solid 2 adhered and precipitated not only on the cathode surface but also on the water passage 3. I was This is thought to be calcium carbonate or calcium hydrogen carbonate, and is thought to be due to the reaction of Ca 2+ + CO 3 2- → CaCO 3 or Ca 2+ + HCO 3 − → Ca (HCO 3 ) 2 occurring. From this, it can be seen that in the conventional electrolyzed water generating apparatus, the white solid precipitates in the electrolyzer, which shortens the electrode life of the electrolyzer and is inappropriate.
