<p><P>PROBLEM TO BE SOLVED: To provide a water purifying material which has versatile applicability, namely, can be used for filtration or biological treatment, if necessary. <P>SOLUTION: This water purifying material 1 of a spherical shape consists of a core material 2 of granular activated carbon 2a being an inorganic carbon material and a filtering fiber layer 3 formed to cover the material 2. The layer 3 is preferably constituted of thermally fusing short fibers one synthetic fiber of which has the melting point relatively lower than that of the other synthetic fiber and at least the surface of one synthetic fiber is melted and bonded to the other synthetic fiber at the contact positions. <P>COPYRIGHT: (C)2003,JPO</p> |
