The present invention relates to a bilge pollution prevention device for ships, and more particularly, the bilge standing on the bottom of the ship is mixed with seawater flowing into the engine room of the ship, such that contamination may occur in the device that can prevent the source. It is about.

In ships, bilge means sewage accumulated on the bottom of the ship, such as water leaked through the shell or pipe on board, water contaminated with oil from the deck, or water from the cargo. If oil-contaminated bilge is released from the ship to the outside of the ship (seawater or land channel), marine pollution can be caused, and each country is strictly controlled by the environmental law.

In recent years, the bilge treatment regulations on board have been further increased, and in certain areas, the allowable content standard of oil contained in the purified water has been strengthened from '15 ppm 'to' 5 ppm '. In this case, if the content of the oil contained in the purified water is not purified to a level below '5ppm', it cannot be released overboard. In addition, the regulations of the International Maritime Organization, which exert global influence, are also known to be strengthened from the current 15ppm to 5ppm.
