Abstract

Ballast water transfers aquatic species among ports and poses biological threat to the world's oceans. This work investigated the use of combined ultraviolet (UV)/Ag-TiO₂+ozone (O₃) processes for ballast water treatment using Escherichia coli and Vibrio alginolyticus as indicator microorganisms. In all tests, the V. alginolyticus cells are more resistant to UV/O₃ inactivation than are the E. coli cells. Bacterial cells under stressing stimulated activities of antioxidants for their protection. The combined UV+O₃ and UV/Ag-TiO₂+O₃ tests yield synergistic removal of both strains compared with individual tests. The combined UV/Ag-TiO₂+O₃ process is potentially applicable for onboard treatments for ballast waters.
