Claim:
An arrangement for cleaning fine solid particles from a continuously flowing liquid suspension, comprising an inlet tank, a feed pipe opening into the inlet tank for continuously supplying the liquid suspension to be cleaned, a sedimentation chamber unit located downstream of the inlet tank, a particle-separating unit located in the sedimentation chamber unit and contains a plurality of parallel, adjacent surface elements inclined at an angle to the horizontal plane, at least two decanting chambers, located above and downstream of the sedimentation chamber unit, with an outlet for cleaned liquid, and a sediment sludge outlet located in a bottom portion of the sedimentation chamber unit, wherein the sedimentation chamber unit comprises at least two sedimentation chambers which are separate from one another, are connected parallel to the inlet tank and each have their own decanting chamber, wherein valve units, coordinated with separate outlets from the respective decanting chambers, are arranged so as to be opened and closed alternately with one another, and wherein an overflow in the inlet tank is arranged so as to keep the liquid surface in the inlet tank and the separate decanting chambers at the same or essentially the same constant level.
