Abstract

Installation for the decantation of wastewater, particularly wastewater from paper mills, characterized in that it is constituted by a tank in which a separating duct prolonged by a baffle is submerged, at least, the wastewater being diverted directly into this duct to prevent them from coming into contact with the water body already in the process of decanting, with the tank, on the other hand, an aerator in which the decanted water, separated at the top of the tank, is introduced.
