Evaluating the contingency treatment performance of advanced electro-catalysis oxidation processes for marine bacteria in ballast water

Effects of ballast water treatment by advanced electro-catalysis oxidation processes (AEOP) on abundance, activity, and diversity of marine bacteria were examined in a full-scale ballast water management system (BWMS) at Yangshan Port, Shanghai, China. Water samples were collected immediately after...
