2108981 9219545 PCTABS00017 In a water treatment plant, contaminants such as CTC are adsorbed onto activated carbon: the contaminants are removed by mixing granules of a metal, e.g. iron fillings, into the contaminant-laden activated carbon. The presence of the metal leads to the chemical breakdown of the contaminant. The cleansed activated carbon may be re-used, with or without separating the iron from the mixture.
