Abstract

Apparatus for clarifying a sludge -containing effluent, comprising a clarification basin (2) , at least one arm (7) able to move over the upper surface of the liquid in the basin; at least one trough (8) supported by the arm so that it can be immersed over part of its height in the liquid of the basin suction tubes (T1 , T2) held relative to the trough , each tube comprising at the top a vertically adjustable sleeve (B1 , B2) opening into the trough , and a means of removing sludge from the trough; the sleeve (B1 , B2) of at least one suction tube (T1, T2) is free to slide vertically relative to the mobile arm (7) supporting the trough and to the tube (T1 , T2) and a reserve of buoyancy necessary and sufficient for keeping the overspill end (E1 , E2) of the sleeve in the trough (8) continuously out of the water is installed on the sleeve (B1 , B2) so that the overspill level of the sleeve adjusts automatically in relation to the level (16) of liquid and sludge in the trough.
