Granular activated carbon is designed for reduction of tastes, odors and dissolved organic chemicals from municipal and industrial water supplies. Manufactured in the United States 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 adsorption of a broad range of high and low molecular weight organic contaminants.

One of the most common applications for activated carbon is the reduction of the undesirable tastes and odors present in many chlorinated water supplies. Activated carbon 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.

For more than 60 years, Calgon Carbon has pioneered leading-edge purification systems for drinking water, wastewater, odor control, pollution abatement, solvent recovery and a variety of industrial and commercial manufacturing processes. That tradition of innovation continues today.

Used in our Whole House filters, the Filtrasorb^® 200 and Filtrasorb^® 400 carbon products are designed to comply with all the applicable provisions of the AWWA Standard for Granular Activated Carbon, edition B604-96; the stringent extractable requirements of ANSI/NSF Standard 61 and the Food Chemicals Codex.
