Installation for the treatment of municipal and/or industrial wastewaters comprising a basin that receives the water to be treated and a series of discs (4) having a packing (G) that are parallel and vertical, mounted on a horizontal shaft (5), partially submerged in the water to be treated, and rotated so that the biomass which grows on the surface of the packing of the discs is alternately brought into contact with the water to be treated and oxygen from the air. The configuration of the packing (G) of the discs (4) is chosen so that the developed surface area of the packing in one zone of the disc increases with the distance from this zone to the axis of rotation (X-X). |
