Heating techniques in ballast water treatment

Ballast water is recognized as a vector for transference of various species from one geographical region to others, all around the world. Consequences are influence on ecology of species in the environment where ballast water is discharged, with the possible impact on human health and/or economy. This paper is a review on different heating techniques that have been tested in accordance with the International Maritime Organization (IMO) propositions, to minimize the number and abundance of species that shift through the ballast water. Studies on heating techniques have shown certain following advantages: low environmental impact as well as economical benefit when utilising the available heat resources on board the ship. Potential disadvantages are achieving high temperatures during short voyages, heat system implementation on ship and insufficient temperatures for treatment of some organisms.
