Abstract
The discharge of ballast water from the marine vessel without proper treatment causes the ecological disruption. Therefore, International Marine Organization(IMO) has the plan to force the proper treatment of ballast water before its discharge to open sea. To satisfy the IMO's criteria, several processes such as filtration, UV irradiation, and ozonation etc., were introduced. Since the disinfection of ballast water should be conducted within very short hydrolic retention time, electrochemical treatment can be a promissing process. The DSA(dimensional stable anode) electrode for the electrochemical treatment was prepared by thermal deposition method. The disinfection rate of microorganisms increased with the increasing current density and reaction time under low pH condition. The morphology of sterilized microorganisms was shown by SEM and Microscopy.
