ABSTRACT:
A ballast water treatment system has a source of hot water from the cooling water overboard discharge associated with the propulsion plant of a cargo or ship vessel. The heat exchangers are placed to receive ballast water from ballast tanks or in ballast tanks. A hot fluid system takes the heat from the overboard discharge and uses it to heat the ballast water as it is pumped through the heat exchangers.
