Ballast Water Monitoring A/S! 7th International Conference & Exhibition on Ballast Water Management 2014! Ballast Water Management Systems! Status:! • BWMS treatment methods include UV, electrochlorination, ozone, pasteurization….! • Some systems monitor performance, e.g. TRO! • None have performance indicators for biological efficacy of treatment! Challenges:! • Representative samples and at the “right time”! • Log to indicate gross compliance! • Avoid PSC detailed inspection in port of arrival! time! !!!! energy!
