PITTSBURGH, PA  –  05/19/2011

Calgon Carbon Corporation’s (NYSE: CCC) wholly owned subsidiary, Hyde Marine, Inc., announced today that its Hyde GUARDIAN® has become the first ballast water treatment (BWT) system to be awarded Type Approval from the Russian Maritime Register of Shipping (RMRS).

As a result of the RMRS Type Approval, which is effective immediately, Hyde GUARDIAN® units may be installed on any Russian-flagged vessel. The RMRS Type Approval was granted for the entire range of Hyde GUARDIAN® systems with treatment capacities from 60 m3/hr to 6000 m3/hr. A Hyde GUARDIAN® unit is scheduled for installation on the Russian arctic container vessel, the MS Norilskiy Nickel, in late summer of 2011 and will have a treatment capacity of 250 m3/hr.

In commenting on the RMRS approval, James A. Sullivan, vice president of Calgon Carbon, said, “Achieving RMRS approval is another example of Calgon Carbon’s ongoing commitment to provide the maritime industry with the leading ballast water treatment systems anywhere in the world.”

Hyde GUARDIAN® systems are chemical free, using filtration and ultraviolet disinfection to treat ships’ ballast water to prevent the spread of aquatic invasive species from port to port. The Hyde GUARDIAN® unit received International Maritime Organization (IMO) Type Approval in April 2009.

Hyde Marine will join its Russian Distributor MARCON-West Ltd. in booth number R4139 at NEVA-2011. The maritime exhibition runs September 20-23, 2011, LENEXPO, St. Petersburg, Russia.

Hyde Marine is a recent addition to Calgon Carbon’s Ultraviolet Technologies Division and is a global leader in the growing BWT market. Hyde Marine has sold more than 100 Type Approved systems to date. For more information about the Hyde GUARDIAN®, visit
