Calgon Carbon's Columbus Plant Receives NSF Certification for Custom Reactivation

PITTSBURGH, PA  –  12/08/2010

Calgon Carbon Corporation (NYSE: CCC) announced today that its Columbus, Ohio, plant received certification from NSF International under NSF/ANSI Standard 61: Drinking Water System Components – Health Effects for custom reactivated carbon for potable water applications.

Calgon Carbon’s Columbus and Blue Lake, California, plants are the only facilities in the U.S. that are certified by NSF International to reactivate spent activated carbon that has been used to treat municipal potable water. NSF/ANSI Standard 61 is the nationally recognized measure to evaluate the health effects for components and materials that come in to contact with drinking water.

Reactivation is a high-temperature thermal process, whereby spent granular activated carbon can be safely and cost effectively recycled back to customer facilities for re-use. During the reactivation process, adsorbed organic compounds are destroyed and the activated carbon’s adsorptive capacity is restored. This results in a cost savings for the customer over the use of virgin carbon. The reactivation/recycling process is also better for the environment, with a reduced CO2 footprint as compared to the manufacture of virgin activated carbon.

To obtain certification from NSF, Calgon Carbon completed a multi-month process that included submission of applications and product samples, data collection and monitoring.

Calgon Carbon Corporation, headquartered in Pittsburgh, Pennsylvania, is a global leader in services and solutions for making water and air safer and cleaner. For more information about Calgon Carbon’s leading activated carbon and ultraviolet technology solutions for municipalities and industries,
