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!

Even the larger 150 μm, 1.7 g/cm3 particles will follow the water quite
closely, and no significant particle concentration difference is expected.!
