Abstract: A settling or sedimentation tank including inlet structures arranged, through whose inlet opening the suspension to be separated flows to the tanks, the height of which can be variably adjusted. In addition to the height variability of the inlet opening, the volumetric flow flowing out of the inlet structure can, depending on the actual load, be directed by forming a horizontally flow-through inlet opening or a vertically flow-through inlet opening and can optionally be divided into horizontal and vertical partial flows QI and QII. As a result of the horizontal inflow, the capacity of the sedimentation tank increases at high loads, and as a result of the vertical inflow, the volume flow through the sedimentation chamber and the turbulent energy in the sedimentation chamber decrease at low loads, so that the retention of fine suspension in the sedimentation tank is increased and thus the effluent quality is improved.
