Definitions
- the present invention relates to a method for treating ship ballast water that can easily and surely eliminate various organisms that inhabit the ship's ballast water.
- ballast water is pumped into the ship before leaving the unloading port, and discharged outside the ship before entering the loading port or when loading the load.
- ballast water is kept in a reduced state for a long time, plankton that requires dissolved oxygen and aerobic bacteria in the ballast water are dormant.
- the cysts in the state tend to breed anaerobic bacteria. This cyst is extremely durable because its outer wall is quite different from the plankton cell wall membrane and has a very strong structure.

- Hydrogen peroxide generated in water containing seawater or fresh water can also be used.
- Hydrogen peroxide can be generated in the working water by electrochemical decomposition of water or an alkaline solution, irradiation of water with high energy rays such as ultraviolet rays or radiation, or aquatic organisms [for example, Poecillia vellifere (medaka Metabolism, etc.).
- Ferrous ions or ferrous ion supplying compounds used in the present invention include ferrous sulfate, ferrous chloride, and ferrous sulfate ammonium. Examples thereof include compounds that are soluble in water and can form divalent iron ions in water. When adding these to ballast water, ferrous ions may be diluted or dissolved in seawater or fresh water as appropriate to achieve the desired concentration.

- iodine or an iodine supply compound may be appropriately diluted or dissolved in seawater or fresh water so as to have a desired concentration.
- the activity of catalase used is 50000 units / ml, an amount that is 0.01 to 50 mgZ L is preferred.
- the hydrogen peroxide concentration is less than 10 mg / L, the organisms that inhabit the ballast water cannot be sufficiently controlled, which is preferable.
- the hydrogen peroxide concentration exceeds 500 mgZL, it is not preferable because a biocidal effect corresponding to the added amount cannot be expected, and hydrogen peroxide may remain after the treatment.
- the ferrous ion concentration is less than 0.1 mg / L
- the catalase concentration is less than 0.5 unit / L
