ABSTRACT:
Method for collecting pollution, especially oil, from a surface contaminated liquid. An oil collecting apparatus is adapted to float on the surface of the liquid. A surface layer of liquid with pollutant is drawn into a rotating hollow rotor by virtue of a liquid vortex established therein. The incoming liquid contacts the overlying surface of a concentrically arranged stator. This contact reduces the rotational velocity of the boundary layer of liquid containing the pollutant. The resultant force urges the pollutant toward the center of the vortex, when it is drawn off through a collecting cavity located centrally of the stator.
