procedure to remove a pollutant of lower density of the surface of water and for implementation of the procedure.

摘要

A vessel for use in removing a floating contaminant liquid such as oil from the surface of water has a hull forming an immersed inverted channel into which surface layers flow as the vessel advances, the hull being shaped so as to guide the liquid into accumulation zones from which the liquid is drawn by a pump into settling tanks disposed in pontoons on each side of the hull, the water being discharged from the tanks and the contaminant liquid being collected in the tanks.
