PITTSBURGH -- May 6, 2013

Hyde Marine, Inc., a wholly owned subsidiary of Calgon Carbon Corporation
(NYSE: CCC), announced today that it has named W&O Supply as its exclusive
sales distributor in the U.S. and Canada for Hyde GUARDIAN^® Ballast Water
Treatment Systems (BWTS).

The chemical free Hyde GUARDIAN BWTS uses efficient filtration and ultraviolet
disinfection to treat ships' ballast water to prevent the spread of invasive
species from port to port. In April 2013, the Hyde GUARDIAN BWTS earned the
Alternate Management System (AMS) approval from the United States Coast Guard
(USCG). It also received International Maritime Organization (IMO) Type
Approval in April 2009 and has Type Approvals from several Class Societies.

According to John Platz, President of Hyde Marine, Jacksonville, Florida-based
W&O will begin selling Hyde GUARDIAN BWTS effective immediately.

“We are pleased to partner with W&O because the company has an outstanding
reputation as a premier engineered-solutions provider committed to meeting the
needs of the maritime industry,” said Platz. “We are excited about the
opportunity to work with W&O to continue the growth of the Hyde GUARDIAN
Ballast Water Treatment System business across the U.S. and Canada.”

“Ballast water treatment system regulations are affecting the entire marine
industry, which is why it was essential to find a trusted and reputable
partner we could work with to bring the best solution available to the
market,” said Michael Hume, CEO of W&O. “We are proud to partner with Hyde
Marine, a 148 year old company known for innovation in the marine industry, to
help educate our customers and find the best BWTS solutions for their vessels
and fleets.” Hume added that W&O will represent Hyde GUARDIAN at the upcoming
Offshore Technology Conference in Houston, Texas, May 6-9, 2013, at the W&O
booth, # 1163.

With 16 stocking locations in the U.S. and Canada, two in Europe and one in
South America, W&O Supply serves all segments of the maritime industry,
including commercial shipping, the U.S. Navy, Military Sealift Command, MARAD,
U.S. Coast Guard, cruise lines, barge owners, upstream oil and gas rigs, and
the shipyards that build and repair vessels of all sizes.

“With the recent announcement of AMS approval, Hyde Marine and W&O are in a
unique position to provide shipowners and operators with ballast water
treatment solutions that meet USCG requirements for operation in U.S. waters,”
said Platz.

AMS approval is an interim measure that allows BWTS to be used on vessels for
five years after the vessel is required to comply with the USCG Ballast Water
Discharge Standards. The five-year period is designed to allow the BWTS
manufacturer sufficient time to obtain U.S. Type Approval and ensure the ship
operator’s compliance with U.S. ballast water regulations into the future.

Tested and validated at the Royal Netherlands Institute for Sea Research
(NIOZ), one of the most challenging ballast water test facilities in the
world, the Hyde GUARDIAN^® BWTS ultimately became the first BWTS accepted into
the U.S. Coast Guard’s Shipboard Technology Evaluation Program (STEP), which
facilitates the development of effective BWTS technologies for vessel owners
seeking alternatives to ballast water exchange.
