Various methods exist for treating ballast water, such as formulated chemical injection, seawater electrolysis, ultraviolet rays, and deoxygenation by nitrogen. Since the original development of the system, we have been constantly striving to ensure its suitability – being on board ships and cooperating with shipping companies from the very beginning. As a result, we have developed a unique system that can balance a high level of treatment performance while minimizing environmental impacts by adopting a combined treatment method using filters and formulated chemicals; a system that can be mounted onboard even those ships with numerous restrictions, such as limited installation spaces and electric power capacities.

Sodium hypochlorite needs to be stored at 20°C or lower. When the chemical drum containing the chemical is delivered onboard, be sure to fill the disinfectant tank using the disinfectant transfer pump as soon as possible.

Sodium sulfite is delivered as a powder. It should be dissolved with freshwater in the Neutralizer Dissolution Unit before being injected to the ballast water.

The BWMS control panel supervises and controls the BWMS with signals (A/I, A/O, D/I, D/O) corresponding to each device.
System operation and individual component operation can be performed on the touch panel. It also has a logging function, and can also show the trend graph.
