ABSTRACT:
A method and device for the separation of substantially solid bodies from a liquid are disclosed in which an obliquely arranged screen grid is provided with an upper region, a lower region, and two opposite edge regions and is suppllied with liquid at the upper region to separate the solid bodies from the liquid in the form of screenings which travel along an upwards facing surface of the screen grid. A cleaning device rests against the upwards facing surface of the screen grid and moves the screenings during movement of the cleaning device horizontally towards the edge regions to cause the screenings to pass onto transport surfaces situated adjacent to the edge regions. The transport surface extends along the length of the screen grid and is smooth.
