Abstract
A system and process for treating ballast water within an ocean going vessel by generating hypochlorite for treating the ballast water. The system comprises one or more hypochlorite electrolytic cells in fluid communication with ballast water. The total organic carbon content of the ballast water is ascertained and the amount of hypochlorite generated is modulated in response to the total organic carbon content of the ballast water. In one embodiment the system comprises a total organic carbon analyzer for measuring total organic carbon content.In one embodiment of the process of the invention, hypochlorite production is modulated so that the residual halogen-containing oxidizing agent is maintained in the ballast water. In another embodiment of the process, hypochlorite production is modulated to maintain a weight ratio of hypochlorite to total organic carbon in the ballast water ranging from about 1.0 to about 3.0.
