Ballast Water Treatment Systems (BWTS)
Ballast Water Treatment System (BWTS) is a system designed to remove and destroy/inactive biological organisms (zooplankton, algae, bacteria) from ballast water. Ballast water treatment is still evolving technology with an ever-growing number of manufacturers. This means that there is limited inservice experience for the systems being offered and there is a general understanding that no single system is suitable for all ship types. See also AQUARIUS ballast water treatment plants.
Descriptions of numerous treatment systems can be found in the ABS notice “Ballast Water Treatment Advisory”
