Abstract: Ballast and/or cooling water biocidal treatment and disinfection systems and techniques are provided. The systems utilize oxidation reduction potential control to regulate addition, or concentration of an electrocatalytically generated biocidal agent to disinfection levels in ship buoyancy and to biofouling levels in ship cooling water systems. The disinfection and biofouling control systems provide suitable treatment while reducing the potential for corrosion of ship components and, in some cases, undesirable disinfection byproducts.

Abstract: A chlorine based biofouling control subsystem is utilized to facilitate shipboard water management systems such as ballast water management that employ filters. The biofouling control system can serve as a subsystem to promote antifouling and reduce the filter clogging due to biofouling, which improves the efficiency and effectiveness of the ballast water treatment management system. An antifouling agent of the biofouling control system breaks up the dense colonies of marine organisms being filtered or treated by the main water management systems.
