Ballast water is used to regulate a vessel’s draft, trim, stability or to maintain stress loads. As seawater is readily available to seagoing vessels, it is the most widely used form of ballast. Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call or wherever more cargo is loaded. Ballast water discharge typically contains a variety of biological materials, including plants and animals that require filtration prior to discharging.
