Ozone System「NK-O3 BlueBallast(※)」

Ozone (O3) is a colorless gas with an irritating odor and is naturally produced in the atmosphere in nature.
It is very unstable and can be decomposed in a short time.
NK company ozone purification system “NK-O3 BlueBallast (*)” injects ozone into ballast water,
In addition to directly killing alien marine invasive species with this strong oxidizing power, it is also reduced by oxidizing compounds produced by reaction with other chemicals in seawater.
Since ozone can only exist in seawater for a short time, it does not harm the water areas where ballasted water is discharged.
