The objective of the proposed project is development of a ballast water treatment system by using a pulsed DC electrical field for microbial inactivation of invasive species in ballast water. The EcoSeaSafe applies an electrical designed pulse shape with instant reversation of the current direction, which generates a reversed electric field that prevents a secondary reaction of radicals which change the water chemistry while fully eliminating target species specified by the gudelines of International Maritime Organisation (IMO). Transfer of invasive marine species by ballast water is a major global ecological and economic problem. As a result, IMO has adopted a convention that requires proper management of ballast water that all ships must comply with progressively staring in 2009. There are, however very few treatment systems that have obtained IMO approval in spite of efforts being done a number of technology developers and vendors. With huge global market for new ballast water treatment technologies, the proposers of EcoSeaSafe have identified a new and big market opportunity that can enable them exploit a superior technology and enhance their competitive position and economic growth as well as international network of cooperation. The EcoSeaSafe system is a cost effective, environmentally accepted, user friendly, compact and safe technology. It has minimal footprint and can be easily installed on new ships and retrofitted on existing vessels without disrupting the structural integrity of the vessel. To attain the technological objectives of the proposed project, innovative developments will be undertaken that include development of innovative pulse generator, a novel radical reactor of innovative alloys and a process control unit for controlling the required pulse frequency, amplitude and shape as well as efficient inactivation with minimal electrode distance.
