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.
A method for the gravitational separation of fine particles from a liquid, comprising the steps of conducting the liquid containing the particles in a unidirectional laminar flow through spaces defined by a plurality of adjacent, essentially horizontally oriented, channel-forming elements in a box-shaped separation unit, interrupting the liquid flow through the spaces when the particle concentration in the liquid, which has passed through the spaces, exceeds a predetermined value, tilting the channel-forming elements to an essentially vertical position about an axis transverse to the direction of the liquid flow for removal of the particles on the channel-forming elements, and returning the channel-forming elements to essentially horizontal working position after cleaning for the commencement of a new gravitational separation cycle.
An arrangement for the gravitational separation of fine particles out of a liquid, comprising a separation unit with a plurality of adjacent channel-forming elements therein, an inlet for the liquid to the separation unit and an outlet from the separation unit for the liquid from which the particles have been separated in the separation unit, the separation unit being pivotable about an axis transverse to the direction of the liquid flow between an essentially horizontal working position, in which the liquid is intended to flow through it for the separation of particles by sedimentation on the channel-forming elements, and an essentially vertical position, in which the particles accumulated on the elements can be discharged from the separation unit.
