PURPOSE:To remove efficiently the chlorine in city water and to soften said water, by passing the city water through an activated carbon filter deposited with silver by fusion or having silver ions then passing the water through an anion exchange resin layer. CONSTITUTION:City water admitted through an inlet pipe 4 and the outlet 13 of a riser pipe 3 is passed through a filter 8 while it fills the inside of an inside cylinder 7, whereafter the water is introduced through an inlet 12 into a clean water pipe 10. The filter 8 consists of an electrified netlike material of activated carbon which is wound to a cylindrical shape. While the city water passes the filter 8, the chlorine in the water is adsorbed on the activated carbon, and the effect of sterilization is provided by the effect of silver ions, by which the water is purified. The clean water in the pipe 10 comes out to the upper part of a tank 1 from an outlet 11, and falls onto an anion exchange resin layer 14. The cations in the sea water are substituted with the anions in the resin during the passage through the layer 14, whereby the water is softened. |
