  • Patent number: 5888406
    Abstract: A skimmer for the removal of thin surface films of petroleum products from a water's surface. The skimmer uses air suction to effectively increase the volume of petroleum product removed, while at the same time being able to handle very thin films effectively. The skimmer uses a movable inner cover which is adjustable to the thickness of the petroleum product's film to reduce the amount of water drawn into the skimmer. An angled flange is also used to pull and concentrate the petroleum within the skimmer. Two vanes are used to maneuver the skimmer across the surface of the water to bring it into contact with the petroleum film on the surface of the water.
