Ozone (Mitsui) Special Pipe Hybrid

摘要

The Special Pipe Hybrid system (Ozone version) from the Japanese shipbuilder Mitsui Engineering is a two-stage system based on cavitation by high shear and ozonation. In the ballasting phase, water is taken into the pre-treatment unit before passing to a unit that injects ozone, which has been generated on board, into the water. This method of treatment starts with inline pre-treatment to preventing blockage of the disinfecting unit followed by a more complex mechanical treatment via a "special pipe" which is inserted into a section of the normal ballast pipe run and then ends by adding the produced ozone which is considered as an active substance by the IMO. After addition of the ozone to the water, for the treatment to be effective it is necessary for the ballast to be stored in the tank for at least 48 hours.
