  • Method and system for biofouling control of shipboard components
    Patent number: 8591740
    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.
