Scholarcy highlights

  • With the prosperity of shipping industry, the discharge of ship ballast water has become a serious threat to marine ecological environment
  • The inactivation effect of UVTiO2 on microalgae and Escherichia coli has been investigated, and the results proved the effectiveness of the UV-TiO2 technique on treating ballast water containing high contents of suspended matter
  • It indicates that the doping of Fe slightly increased the inactivation effect of Escherichia coli and Enterococcus
  • The results indicate that the UV and Ag-doped nano-TiO2 treatment surely has more remarkable inactivation effect than the sole UV treatment
  • To improve bacterial inactivation effect for ship ballast water treatment, Ag, Fe, and Gd were doped to nanoTiO2 at different ratios to prepare
  • UV and Ag-doped nano-TiO2 treatment resulted in higher MDA contents and lower Superoxide dismutase activities, which provides theoretical explanation for high inactivation rates in these cases
