Ballast water treatment equipment manufacturer Hyde Marine provides systems for all sizes and manners of vessels, but increasingly, the U.S.-based subsidiary of Calgon Carbon Company is being recognized for its work with offshore operators – here and abroad. Hyde Marine has long been active in the worldwide effort to control the spread of aquatic invasive species in ballast water. Early on, Hyde supplied the first fully operational shipboard Ballast Water Treatment system. In 2003, after requirements were better defined, Hyde installed a state-of-the-art filtration and UV disinfection system aboard the Coral Princess. This system was tested extensively on land-based installations and on board the Coral Princess in the fall of 2004.
