Lloydâ€™s Register has released a new Guide to Ballast Water Treatment Technology that provides an independent and impartial description and appraisal of commercially available and developing technologies for ballast water treatment. It is the result of work conducted by the internationally respected Center for Water Science at Cranfield University, UK on behalf of Lloydâ€™s Register. The treatment of ballast water is one of the most significant environmental and operational challenges facing the marine industry today. In the face of new legislation, ship operators will need to choose a ballast water management solution that will work for them. The new Guide is intended to provide an overview of the current status of ballast water treatment technologies. A global requirement for ballast water treatment arises from the International Convention for The Control of Shipsâ€™ Ballast Water and Sediments, which will require certain ship types to use treatment systems from January 1, 2009.
