Granular activated carbon is designed for reduction of tastes, odors and dissolved organic chemicals from municipal and industrial water supplies. Manufactured from select grades of bituminous coal to produce a high density, durable granular product capable of withstanding the abrasion and dynamics associated with repeated hydraulic transport, backwashing and mechanical handling. Activation is carefully controlled to produce exceptionally high internal surface area with optimum pore size for the absorption of a broad range of high and low molecular weight organic contaminants. One of the most common applications for High Activated Carbon (HAC) is the reduction of the undesirable tastes and odors present in many chlorinated water supplies. HAC has been successful for many years in the reduction of free chlorine from water supplies. The end product is clean, fresh water with no objectionable taste or odor characteristics. To obtain maximum efficiency of the activated carbon in the absorption process, it is desirable to have the greatest possible surface area in the smallest practical volume. This is necessary because the rate of absorption is proportional to the amount of surface area of the absorbing medium media. HAC has a surface area of 900 square meters per gram. This results in high-efficiency and greater system economy. HAC requires periodic backwashing to eliminate accumulated suspended matter and to re-grade the filter bed. HAC has replaced when the filter bed loses the capacity for reduction of taste and odor. HAC may be used in either domestic or industrial applications using gravity flow or pressurized filter vessels.
