Abstract
A method is for the treatment of ballast water, in which the ballast water is carried into a ballast tank via a down pipe and in which an underpressure created at the upper portion of the down pipe induces the formation of gas bubbles in the ballast water. Before flowing into the down pipe, the ballast water is carried via a throttling device into a closed container at the upper portion of the down pipe, the closed container having a flow area larger than the flow area of the down pipe.
