Title:
BALLAST WATER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/108301
Kind Code:
A1
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.
