<P>PROBLEM TO BE SOLVED: To provide a simple structured, compact, and efficient adsorption device and recovery device which efficiently capture, adsorb, and recover metallic components, such as Mn and Fe, contained in ground water, well water, or the like. <P>SOLUTION: In the adsorption device for the metallic components in water, made by multilayer nonwoven cloth filters, the surfaces of which have a metal-capturing functional groups, and spacers, a packed bed is formed in a column container by laminating the nonwoven cloth filters through the spacers which have net-like penetration holes, and raw water is made to penetrate the packed bed to adsorb and remove the metallic components. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
