Calgon Carbon Awarded Two Contracts for Sentinel Systems

Two Indiana cities will install systems at drinking water treatment plants

Calgon Carbon Corp. announced yesterday that it has been selected by the cities of Indianapolis and Fort Wayne, Ind., to supply Sentinel Ultraviolet (UV) Disinfection Systems at drinking water production plants serving those communities.

Indianapolis will install 12 Sentinel 12-in. Systems at its Fall Creek plant to increase protection against Cryptosporidium, Giardia and other surface water pathogens. When installed in winter 2011, the Sentinel Systems will treat up to 44 million gal of drinking water per day.

Fort Wayne will install three Chevron 48-in. UV reactors at its Three Rivers water filtration plant as part of a retrofitting project. The new UV reactors, capable of treating up to 72 million gal of water per day, were selected because of their low capital and operating costs. Installation is scheduled for June 2012.

Both Sentinel Systems have undergone third-party validation in accordance with the U.S. Environmental Protection Agency's UV Disinfection Guidance Manual. Both systems feature UV intensity sensors to ensure accurate delivery of UV dose, automatic quartz sleeve cleaning systems and fully automated control systems.

"We are pleased to have been selected to supply our Sentinel disinfection systems to the cities of Indianpolis and Fort Wayne," said Calgon Carbon Vice President James A. Sullivan. "These awards are indicative of Calgon Carbon's growing leadership position in the UV disinfection market."
