Abstract: The present invention concerns a flow regulation device for waste waters, characterized in that it comprises a flood-weir constituted by a tubular member of preferably hard synthetic material, i.e., polyester. The tubular member includes an S-shaped channel which is defined by baffles and a profiled discharge wing. A reduction adapter having a tubular tapered element and an overflow member, coupled to the top thereof, is upstream of and coupled to the waste-weir.

Abstract: A device for regulating the rate of flow of waste water mixed with clear rainwater is disclosed. The device includes a collector chamber having a first orifice which receives the mixed water and second and third orifices which respectively discharge water containing a high concentration of waste water, and clear water. An adjustable device including first and second conical elements connected in series is mounted between the first and the second orifices. The first conical element has a lateral opening which extends into the second conical element. The effective area of the opening in the second conical element is controlled by a vertically movable shield. A first boss and a second boss settle the turbulence in the mixed water which enters the device. A deflector partially blocks the inside of the first conical element and diverts the lighter clear water through the opening.
