This work investigates the use of electrolysis for ballast water treatment. The total residual oxidant (TRO) generation and microalgae inactivation were examined, and the effects of hydraulic residence time (HRT), current density, and water salinity were evaluated. Results show that TRO could be generated by seawater electrolysis, and the produced TRO concentration was positively correct with HRT, current density, and water salinity. The increase in water salinity decreased energy consumption, while the effects of HRT and current density on energy efficiency were complex. The persistence of TRO resulted in algae inactivation in the effluent. Considering efficiency and cost, electrolysis technology has advantages in ballast water treatment.
