PURE TRADITION

Throughout history, Calgon Carbon has been a pioneer in creating new activated carbon products, systems and services.

Innovations

Over 20 years ago, Calgon Carbon introduced an advanced UV oxidation process to remediate contaminated groundwater. In 1998, we followed that up with the first radical breakthrough in the treatment of drinking water in decades, when our scientists invented a process that could be used to inactivate Cryptosporidium and other similar pathogens in surface water, rendering them harmless to humans. This inventive process placed Calgon Carbon on the leading edge of UV disinfection technology. With the Sentinel® line for drinking water, the C3 Series for wastewater, and the Rayox® line for groundwater and process water, Calgon Carbon continues to lead the marketplace with innovative UV technologies.

From the use of granular activated carbon (GAC) for taste and odor removal in the early 1960’s, to the development of ultraviolet light technology for pathogen control in the late 1990’s, to the application of ion exchange technology for removing perchlorates starting in 2000, Calgon Carbon continues to be a pioneer in making water safer and cleaner.
