Sustainable Ballast Water Management Plant

Funding: STREP-project in the 6th EU framework programme
Project Duration:: 15.11.2006 - 30.06.2010
Project Manager: Dr. Gerhard Schories

Maritime transport is of fundamental importance to Europe and the rest of the world. Over 90% of European Union external trade goes by sea and more than 1 billion tonnes of freight are loaded and unloaded in EU ports per year. Shipping is the most important mode of transport in terms of volume, and will remain it for the foreseeable future.

Transfer of species in ballast water started as early as shipping trade. The movement of some 3 to 12 billion tonnes of ballast water (BW) in ships internationally each year has been responsible for the settlement of about 100 million tons of sediment. Its cleaning and the disposal of the ballast sludge produced involve enormous costs, (approximately 30.000 € for a small bulk carrier). Besides these economic aspects, BW has been recognised as a major vector for the translocation of aquatic species across bio-geographical boundaries. It is estimated that as many as 10,000 alien species of plants and animals are transported per day in ships around the world. As ships travel faster and world trade grows, organisms are better able to survive the journey, using the settled sediments as a substrate, and the threat of invasive species from ballast water increases.

Aim of the project is the development of a new hybrid ballast water treatment technology (UV, filters and electrolysis) into a self-controlled BW treatment system. The main objective of the proposed project is the invention of an effective treatment technology incorporating non permanent, seawater-generated active substances as a necessary measure to UV and Filter treatment technology. By producing active substances through electrolysis of sea water, there will be no need to carry or store hazardous and corrosive chemicals onboard ships. It also represents a more economical alternative to using chemicals for treating large volume of ballast water onboard ships.
