Abstract

A disinfector for disinfection of ballast water comprising a housing having an inlet and outlet for the transmission of ballast water through the housing; a plurality of electrodes in the housing representing anode and cathode electrodes; wherein each of said electrodes includes an array of apertures distributed over at least a portion of the electrode so as to permit the ballast water to flow through the electrode.
