Introduction
he ballast water and sediments carried by ships have been identified as a major pathway for the transport of harmful invasive aquatic organisms and pathogens. Ships often take on ballast water in one port and carry such ballast to other ports where it is discharged. The ballast water and sediments contain living organisms which, despite the harsh conditions in the ballast tanks and piping systems, survive to compete with native species in the port of discharge. If the non-native organisms have few natural predators or other natural controls they may become invasive and change the local ecosystems, sometimes dramatically. The direct economic impact of aquatic invasive species, as well as the potential long term damage to the health of the local marine environment and the people who depend on that environment has been well documented. International, national and regional regulations have been implemented to control the transport of the aquatic organisms. The current efforts rely on ballast water management (BWM) practices, including ballast exchange, and other measures aimed at preventing or minimizing the uptake and discharge of contaminated water

or sediment when ballasting or deballasting. These methods may not be completely effective in preventing invasive species and furthermore are often not required if the safety of the vessel would be at risk during the exchange. Systems that treat ballast...
