Abstract

Clarifying vessel has a rotationally symmetric shape. The bottom of the pref. cylindrical vessel gets lower from the centre towards the wall and runs into the wall via a groove. The vessel has no hydrodynamically impeding structure and on the outer edge of the bottom several closable outlets are provided.
