Evaluating the biological efficacy of a ballast water management system using filtration and electro-catalysis with an accurate definition of holding time

We employed a mesoscale experimental system and enriched natural plankton communities to investigate the efficacy of a type of ballast-water management system (BWMS) that uses a combination of filtration and electro-catalysis as the treatment technology. The water samples were collected immediately...
