Cosco Water Ballast Treatment System Blue Ocean Shield is a modularized Ballast Water Management System, uses the combination of filtration and UV disinfections. Filtration system works before the UV system, it can remove particulate matter (PM) as well as the plankton over 50 um. Filtration and back flushing don't affect the UV processing. The UV ray produced by the UV system can destroy the bacteria, algae and other microorganisms in the treated water. |
