    Patent number: 5501803
    Abstract: A method and apparatus for separating from a base liquid, particles contained therein by introducing the base liquid between facing rotating surfaces which are imparted mutually different speeds of rotation relatively to the environment. The method is carried out in a container holding the liquid, wherein the two facing surfaces are rotationally symmetrical about an axis and preferably are in contact with the liquid in their entirety, and wherein the surfaces are used for radial boundary-layer transportation of the particles to be separated.
