History and Timeline of Activated Carbon Giant <br />Page 2 of 6 <br />cutting -edge purification systems for drinking water, wastewater, odor control, pollution abatement, <br />and a variety of industrial and commercial manufacturing processes. <br />Innovations <br />Over 20 years ago, Calgon Carbon introduced an advanced UV oxidation process to remediate <br />contaminated groundwater. In 1998, we followed that up with the first radical breakthrough in the <br />treatment of drinking water in decades, when our scientists invented a process that could be used to <br />inactivate Cryptosporidium and other similar pathogens in surface water, rendering them harmless to <br />humans. This inventive process placed Calgon Carbon on the leading edge of UV disinfection <br />technology. With the Sentinel® line for drinking water, the C3 Series" for wastewater, and the Rayox® <br />line for groundwater and process water, Calgon Carbon continues to lead the marketplace with <br />innovative UV technologies. <br />From the use of granular activated carbon (GAC) for taste and odor removal in the early 1960's, to <br />the development of ultraviolet light technology for pathogen control in the late 1990's, to the <br />application of ion exchange technology for removing perchlorates starting in 2000, Calgon Carbon <br />continues to be a pioneer in making water safer and cleaner. <br />A Tradition of Innovation <br />1942 <br />Pittsburgh Coke & Chemical Company, <br />Inc. pioneers the development of coal- The "Pittsburgh Pulse Bed" system is <br />based granular activated carbon for use H introduced — the first activated carbon <br />*4 system for sugar decolorization. <br />in military protection. <br />1960 <br />The Activated Carbon Division of <br />Pittsburgh Coke and Chemical pioneers <br />1955 <br />1962 <br />The Activated Carbon Division reaches <br />the use of granular activated carbon in H a major milestone when 40,000 pounds <br />drinking water treatment. <br />of bituminous coal -based granular <br />activated carbon is installed for the <br />http://www.calgonearbon.com/about/history/ <br />3/9/2017 <br />
