Apparatus for removing a pollutant from the surface of water comprising, a funnel-shaped weir, means for floating the weir in the water, a flexible disk with its center suspended above the weir and above the still water line and having an edge surface contacting the water adjacent but spaced from the circumference of the weir so as to form an airtight seal against the water, said disk being sufficiently flexible to follow the surface contours of waves, thereby preventing performance degrading wave reflections and air entrainment, means for applying suction to the weir, and means for transporting pollutant from the weir to pollutant collection means.
