A system and process for de-halogenating ballast water before releasing the ballast water from the vessel. In one embodiment, the system comprises a means (150) for measuring the halogen content of the ballast water, a reducing agent source (210) in fluid communication with the ballast water, and a means (230) for controlling the amount of reducing agent supplied to the ballast water. In one aspect, the means for measuring the halogen content comprises one or more oxidation/reduction potential analyzers. In another embodiment, the system comprises one or more hypochlorite electrolytic cells (130) for generating hypochlorite to treat the ballast water. One embodiment of the process for de-halogenating ballast water comprises measuring the oxidation/reduction potential of the ballast water and adding one or more reducing agents to the ballast water to de-halogenate the ballast water in response to the measured oxidation/reduction potential. In one aspect, the oxidation/reduction potential is modulated so that excess reducing agent is present in the ballast water. |
