Abstract
The invention relates to a method and an apparatus for the gravitational separation of fine particles out of a liquid. The liquid containing the particles which are to be separated is conducted with laminar flow through the gaps between a plurality of closely separated, essentially horizontally orientated surface-forming elements (16). The liquid flow through the gaps is interrupted when the particle concentration in the liquid which has flowed through the gaps exceeds a predetermined value. The surface-forming elements (16) are repositioned to an essentially vertical discharging position in order to remove the particle collection present on the surface-forming elements. The surface-forming elements (16) are then returned to the essentially horizontal working position and a new gravitational separation cycle begins.
