<p>A surface skimming method and apparatus for circular clarifiers which collects and removes floating matter from the surface of the clarifier. The surface skimmer includes a rotating arm, a fixed anti-rotation arm, and means for removal of collected floating matter. The rotating arm projects above the surface of the clarifier for rotation thereabout pushing the floating matter ahead of it. As the rotating arm approaches the anti-rotation arm, a "wedge" is formed therebetween which traps the floating matter. As the rotating arm continues to rotate, the "wedge" is made smaller and moves outward, forcing the floating matter towards the means for removal of the collected floating matter.</p> |
