Claim:
1. A process for the production from partially decomposed organic matter of a sorption media for use in the treatment of aqueous solutions to remove at least one type of aqueous contaminant, comprising the steps of: (a) supplying an amount of the partially decomposed organic matter to a granulating machine; (b) granulating the partially decomposed organic matter; (c) drying the granules; (d) thermally activating the granules without chemical activation using an activation heat medium at a temperature of about 175-287° C., wherein the granule has a Ball-Pan Hardness number of about 75%-100% and is suitable for sorption of the aqueous contaminant found in the aqueous solution; and (e) chemically treating the thermally-activated granule, comprising: (f) wherein the thermally-activated and chemically-treated granules can sorb the aqueous contaminant from the aqueous solution without introducing the media contaminant into the treated aqueous solution.
