Description

Apparatus for sterilizing ballast water in ship}

The present invention relates to a ballast water sterilization treatment apparatus for sterilizing microorganisms or pathogens present in the ballast water flowing into the ballast water storage tank.

In general, a ship carrying cargo is filled with a heavy material, that is, a ballast, inside the hull in order to maintain the stability and balance of the ship when the cargo is unloaded. As the ballast, heavy materials such as sand, gravel, and coke are often used, but seawater, which can be easily obtained from the sea, is usually used. Thus, when the ship is sailed, the hull is to maintain the balance and stability of the ship. The seawater filling the inside is called ballast water.

It is known that 80% of the goods produced on the earth are moved internationally by ships, and about 3 to 5 billion tons of seawater are moved internationally every year for such movements. Due to the international movement of goods by ships, foreign marine micro-organisms that are attached to the outside of the ship or transferred as part of ballast water are threatening the local marine ecosystem. Influx of exotic species through this route is recognized as one of the factors that disturb marine ecosystems, and disturbance of marine ecosystems is regarded as a more serious reality than simple marine pollution in terms of extinction of indigenous organisms and destruction of marine ecosystems. Is being introduced.

In order to prevent ecological and economic damages caused by the movement of ballast water and to conserve biodiversity, the International Maritime Organization (IMO) announced in February 2004 that the “International Convention for the Control and Management of Ship Ballast and Sediment” Adopted. In addition, by the end of 2015, ships engaged in international voyages are required to be equipped with ballast water treatment systems.
