バラスト水システム
Document Type and Number:
Japanese Patent JP2007537036
Kind Code:
A
Abstract:
A system and method for treatment of water contaminated with organisms, in particular ballast water in ships, the system including a pump ( 5 ) pumping water from the sea trough a cavitation unit ( 7 ) and into one or more ballast tanks. The cavitation unit ( 7 ) will introduce a strong cavitation in the water, the cavitating action destroying any organic tissue and cell membranes of organisms present in the water. In the cavitation unit ( 7 ) hydrogen and steam are added to the water, while oxygen is removed. The oxygen-depleted water will exhibit a reduced corrosive effect on the ballast tanks.
