Abstract
The disclosure relates to the use of ultrasound for treating ballast water in ships. Specifically the invention discloses the use of ultrasound to activate chemicals to significantly improve there disinfectant properties at low concentrations. Ultrasound chemical activation allows for sonication of only a portion of the incoming ballast water, greatly increasing the cost-effectiveness of ballast water treatment. The ballast water treatment system may integrate with new or existing shipboard ballast systems attaching to the ballast inlet mains; mixing, sonicating and delivering the active substance as it feeds into the ballast tanks. Alternatively, when space or other factors are an issue it can be designed to achieve the same mixing, sonication and delivery from a small apparatus attached to the ballast tanks.
