- the addition of hydrogen peroxides to seawater or fresh water may be before and / or after adding physical means to seawater or freshwater. Or, after pumping fresh water and adding hydrogen peroxide, add physical means to the sea water or fresh water before being injected into the ballast tank, and shear the sea water or fresh water to which hydrogen peroxide has been added. It is preferable from the viewpoint of the aquatic organism control effect to generate stress and / or cavity.
- the retention time may be appropriately selected according to the concentration at the time of addition of hydrogen peroxides, the temperature of the ballast water, the type and amount of aquatic organisms that inhabit the ballast water, and the like.
- the treated ballast water may be retained for a long time when the concentration of hydrogen peroxide added is low and for a short time when the concentration is high.
