Calgon Carbon Corporation Acquires German DVGW W294 Certification For Sentinel ™ UV Disinfection Reactor

This certification is only one of the two industry standards / protocols accepted worldwide by the drinking water industry and governmental regulatory agencies. This milestone will accelerate Calgon Carbon's penetration into the Drinking Water Market, and further enhance the position of the Sentinel™ product line as a leading contender for providing Validated Surface Water UV Systems.

Wayne Lem, senior process engineer for Calgon Carbon relates; "This Certification is only a first effort in a series of forth coming Medium and Low Pressure model certifications, particularly with regard to large flow/ high UV dose capacity reactors. Obtaining reactor certification is required and necessary, in order to standardize and guarantee the performance of systems which the general public is depending upon to safe guard their drinking water." Calgon Carbon is proud to have the two largest operating Medium Pressure UV Disinfection Reactors in the world used as a Cryptosporidium and Giardia barrier.

Chuck Fluharty, Director of Sales and Marketing for Calgon Carbon states; "Calgon Carbon has committed substantial resources to the DVGW and other Certification Processes and will continue to do so, along with working closely with Design Engineers and End User Clients, to foster understanding and acceptance of Calgon Carbons' CFD Modeling data and its close correlation to bioassay tests and studies. It is our intention to design and build UV products for worldwide distribution".
