Abstract
To expel volatile contaminants from a liquid body, outer air is introduced into a perforated container arranged below the liquid surface and having an open bottom by the action of a suction blower creating an underpressure above the liquid surface. Air bubbles exiting through the perforated top wall of the container entrain the volatile contaminants and expel the same into the underpressure area. The air receiving perforated container is either suspended on a float or fixedly arranged relative to the bottom of the receptacle.
