PURPOSE:To prevent generation of rotten matters and algae by adsorbing and removing impurities such as trihalo methane, miscellaneous bacteria and the like which cause to generate rotten matters and algae in a water storage tank, and further dissolving mineral ions into water within the water storage tank. CONSTITUTION:A porous-polyelemental mineral 5 is mixed in the water storage tank 3 to adsorb and remove various impurities in water within the water storage tank 3 and mineral ions are dissolved into water within the water storage tank 3. The mineral known as the porous-polyelemental minerals include a mineral called quartz diorite. When this porous-polyelemental mineral is placed in the water storage tank, potassium ions (K<+>), sodium ions (Na<+>), calcium ions (Mg<2+>), ferrous ions (Ca<2+>), chrorine ions (Cl<->), sulfuric acid ions (So<2->), hydrocarbonic acid ions (HCO<->3), and the like separate from the surfaces of mineral crystals and are dissolved in water. |
