Title: Water purifying agent and its production
Inventor: ARITA MICHIHARU
IPC: C02F1/50
Filed: 1987-11-14
Abstract: PURPOSE:To enhance sterilyzing effect of a water purifying agent and to permit safe usage of treated water by depositing copper oxide to a porous inorganic carrier to be used for the water purifying agent. CONSTITUTION:Aq. soln. of a copper salt such as copper nitrate, etc., is diffused and impregnated into a porous carrier (e.g., silica gel, zeolite, porous mineral such as pearlite, etc.) having adsorptivity. The copper salt is deposited in the form of copper oxide to the carrier by calcining the impregnated carrier to obtain thus a desired water purifying agent. Water is purified by destroying algae and bacteria by circulating water to be treated through this carrier. In this case, the amt. of eluted Cu<2+> ion provides an appropriate concn. for destroying algae and bacteria causing no fluctuation. Accordingly, the control of the concn. is facilitated causing no trouble to other livings due to excess of concn. of Cu<2+> ion, so the treated water can be used safely.
