Zusammenfassung:	PURPOSE:To obtain a granular material useful as a carrier, by a method wherein water is added to activated sludge incineration ash to be kneaded therewith and the resulting kneaded mixture is formed into a plate shape by compression molding while the plate-shaped molding is crushed after ageing. CONSTITUTION:Water is added to activated sludge incineration ash to be kneaded therewith and the resulting kneaded mixture is subsequently formed into a plate shape by compression molding using a compression molding machine. Thereafter, the plate-shaped molding is allowed to stand for several hr at ambient temp. to be aged and the hardness thereof is increased. Subsequently, the aged plate-shaped molding is crushed by a crusher and treated with a screen apparatus to obtain a granular material having a particle size of 0.25-2.0mm. This granular material is utilized for the treatment of activated carbon as a carrier. By this method, manufacturing cost can be reduced.
