Project Summary
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 a year are loaded and unloaded in
EU ports. Shipping is the most important mode of transport in terms of
volume. Furthermore, its history and the effects of globalisation, maritime
transport will continue to be the most important transport mode in developing
EU trade 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 BW 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.
