Abstract
A gas lift pump apparatus for treating ballast water includes a column through which a liquid medium, such as seawater, may be pumped by gas lift. The apparatus includes a delivery device for delivering a flow of a gas into the liquid medium, and a resonance chamber that generates ultrasonic energy therein by the flow of the gas therethrough. The apparatus is operable to launch the ultrasonic energy into the liquid medium in the column.
