ABSTRACT:
A granulated activated carbon is produced by spherically agglomerating activated carbon powder in an aqueous slurry in the presence of a bridging liquid and a binder. At least about 50% of the carbon powder has a surface area of from about 2800 to about 3500 m.sup.2 /gm, an iodine number of from about 2500 to about 3500 mg/gm, a total pore volume of from about 1.0 to about 2.8 cc/gm, and a bulk density of from about 0.27 to about 0.32 gm/cc. The granules are activated by treatment with steam to provide granules having particle diameters of from about 0.17 to about 0.71 mm, and pore size distribution and adsorptive capacity essentially unchanged from that of the carbon powder. The granules are particularly effective for the treatment of drinking water to reduce the level of undesirable contaminants.
