Powdered Activated Carbons are used by water treatment plants for taste and odour control and to ensure the removal of organic chemicals. PACs are added early in the treatment process to enable a period of sole contact time before other treatment chemicals are added to the water stream.
Different types of activated carbon are suited for various specialized applications Granulated activated carbon dechlorinates water, adsorbs organic material and produces a chemical-reducing environment Granulated activated carbon impregnated with silver salts inhibits the growth of bacteria An Evaluation of Activated Carbon for Drinking Water Powdered activated carbon (PAC) is now more commonly used in the United States than is GAC. It generally added to control taste and odor at points in the water treatment plant, ranging from the water supply intake to just before the rapid sand filter. PAC is removed either in the sedimentation basin or by the rapid sand filter.
