<p><P>PROBLEM TO BE SOLVED: To effectively elute an effective component such as iron and silica from the carbonated/solidified body, which is obtained by solidifying an uncarbonated calcium-containing raw material by a carbonation reaction, when the carbonated/solidified body is sunk in the water. <P>SOLUTION: A microbe for producing an acid in the water is stuck to the carbonated/solidified body and the microbe-stuck carbonated/solidified body is sunk in the water. The effective component of the carbonated/solidified body is dissolved by a very small quantity of the acid to be produced by the microbe stuck to the carbonated/solidified body and eluted effectively into the water. Since the effective component is eluted little by little over a long period of time by the acid to be produced by the microbe, the supply of the effective component to the water is continued over a long period of time. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
