Treatment of ballast water using acoustic cavitation techniques coupled with advanced oxidants

Academic Article


  • This research investigates the mixing of marine species in different ecosystems. As ships dock in different ports, they exchange water from the ship's ballast tank and the marine environment. The transfer of water seems insignificant until the ship enters a different port and ecosystem and releases foreign organisms from the ballast tank to the marine environment. These organisms are foreign to the environment that they have been placed in, and, as a result, they may over-produce and cause environmental and ecological problems. To solve this problem, a transducer was found that could create sonic waves at different frequencies through the water and reach the ships' hulls. The sonic waves inactivated foreign organisms in the hulls of ships. This research's objective is to test the effectiveness of this device and the sonic waves at a frequency of 1.4 KHz, also searching to find an optimum length of time for sonication. In addition, the effectiveness of sonication coupled with an advanced oxidant, hydrogen peroxide, was tested in comparison to sonication alone to determine if advanced oxidants can effect the eradication of foreign organisms in the ballast of ships.
