PORTABLE HARDNESS REGULATING DEVICE FOR REGULATING HARDNESS OF POTABLE WATER

摘要

The portable device of the present invention for regulating the hardness of drinking water includes a collapsible electrode group (20) including ion-adsorbing electrodes (21) and (22) and a power supply (13) for applying a voltage between the ion-adsorbing electrode (21) and the ion-adsorbing electrode (22). The first ion-adsorbing electrode (21) includes a first electrically conductive material capable of adsorbing ions. The second ion-adsorbing electrode includes a second electrically conductive material capable of adsorbing ions. In an example, a voltage is applied between the first ion-adsorbing electrode (21) and the second ion-adsorbing electrode (22), with the first and second ion-adsorbing electrodes (21) and (22) being immersed in the drinking water (25). The applied voltage regulates the amount of ions adsorbed on the first and second electrically conductive materials, and thereby the hardness of the drinking water is regulated.
