Hyde Marine, a wholly-owned subsidiary of Calgon Carbon Corporation, has announced the completion of the shipboard testing of its Guardian-US ballast water treatment system. The tests were carried out in accordance with the DNV-GL created QAPP (Quality Assurance Project Plan) under the supervision of a DHI test team.

Steve Schott, Calgon Carbon’s President and CEO said: “This is an important achievement as it was our last phase of testing required in order to apply for USCG Type Approval. It was critical to meet our customers’ needs by testing in varied and challenging conditions.”

The final tests were conducted in challenging ‘sweet’ fresh water with less than 1 psu, completing shipboard testing in all three salinities.  This testing was performed under the direction and supervision of DNV-GL which is serving as an Independent Laboratory per the requirements for U.S. Coast Guard Type Approval testing.  The completion of tests in all three salinity ranges and at multiple temperatures and spanning seasons proves both the function and robust design of the chemical-free Hyde GUARDIAN-US™ Ballast Water Treatment System (BWTS).

Hyde Marine is one of the world’s most successful ballast water treatment (BWT) technology companies with more than 500 of its ballast water treatment systems sold to date. The Hyde GUARDIAN-US BWTS uses space efficient filtration and ultraviolet disinfection to treat ships' ballast water to prevent the spread of invasive species from port to port.

“Hyde Marine is very pleased to have completed our testing requirements,” said Chris Todd, Executive Director of Calgon Carbon UV Technologies/Hyde Marine. “Using one of our first customers as an upgrade platform to prove we could retrofit one of our earliest systems to our newest product was a milestone in which Hyde Marine takes great pride.  Our platform proved a strenuous test of our system’s functionality as we work to define the limits of machine operation and disinfection efficacy.  We are very satisfied with DHI’s analytical approach as well as their enthusiasm to challenge our system in the shipboard testing environment.”

The Hyde GUARDIAN-US BTWS was tested with water containing organism counts far exceeding IMO and U.S. Coast Guard testing requirements and was tested with water with UV transmittance down to 40% UVT.  “We are confident that our system can perform to the expectations of our clients anywhere their vessels may go,” said Todd.

Hyde Marine will now complete the application process and expects to submit their application to the U.S. Coast Guard by the end of 2019.
