Calgon Carbon to Supply United States’ Largest UV Drinking Water System

Calgon Carbon Corp. announced at the annual WEFTEC Technical Exhibition and Conference that its UV Technologies Division has been selected to supply Sentinel UV Disinfection Systems for the Washington (D.C.) Suburban Sanitary Commission’s (WSSC) Potomac Water Filtration Plant. When installed, it will become the largest ultraviolet system for disinfection of drinking water in the U.S., treating up to 300 mgd.

The Potomac Water Filtration Plant (WFP) serves over 1.6 million people in Montgomery and Prince Georges counties in Maryland. The WSSC will install Calgon Carbon’s Sentinel UV Disinfection Systems as part of major improvements to the Potomac WFP to meet future water demands and to increase protection against surface water pathogens.

A total of 12 Sentinel 48 UV reactors will be installed beginning in 2007. The Sentinel 48 is the largest UV reactor in the industry, capable of treating up to 40 mgd per reactor. The Sentinel 48 has been third-party validated in accordance with the EPA’s UV Disinfection Guidance Manual draft. Calgon Carbon’s rigorous validation process supports WWSC’s goal to provide safe drinking water to their customers and comply with current and pending EPA regulations for the control of Cryptosporidium, Giardia and other waterborne organisms.

Commenting on this announcement, James Sullivan, general manager of Calgon Carbon’s UV Technologies Division, said, “We are pleased to have been selected to supply our Sentinel disinfection systems to WSSC. This award represents WSSC’s confidence in Calgon Carbon’s UV Technologies as well as the continued acceptance of UV disinfection by major drinking water providers throughout North America.
