Sucesses for Sentinel® UV Disinfection System

Calgon Carbon Corporation have announced four significant achievements of its new UV Technologies Division - two contract awards valued at more than $900 thousand for the supply of Sentinel® UV Disinfection Systems for the inactivation of cryptosporidium and giardia; the signing of a license agreement by the Oakmont Water Authority in Oakmont, Pennsylvania which will permit the Authority to operate a Sentinel® UV Disinfection System (Sentinel System) for disinfection of drinking water; and third party validation of two Sentinel® reactor designs.

Calgon Carbon received contracts for Sentinel Systems from the City of Kelowna in B.C., Canada, and from the U.S. Army in Gouveneur, New York. When these systems are installed later this year, they will treat more than 70 million gallons of water per day. Calgon Carbon has patented the application of low-energy ultraviolet light for the inactivation of cryptosporidium and other pathogens.

The company offers water producers a license to utilize its cost-effective UV technology. Under its agreement with Calgon Carbon, the Oakmont Water Authority will pay the company a fee of $0.015 per thousand gallons treated. Oakmont's Sentinel System, which was purchased from Calgon Carbon in 2003, treats up to 11.4 million gallons of water per day.

Calgon Carbon also recently completed third-party validation tests on two Sentinel reactor designs, including a 48-inch diameter reactor, the highest flow reactor for the disinfection of drinking water available in the marketplace.
