The coupling of a sewer treatment station to a treatment plant for the flocculation and flotation of water streams and the insertion of said treatment plant for the flocculation and flotation of water streams into a water treatment station. The sewer treatment station is installed upstream from the flocculation and flotation treatment station, in such a way that the outlet of said station is directly connected to the inlet of the flocculation and flotation treatment plant disposed next to the stream bed or next to and interconnected thereto by means of a varying flow canal. The insertion has dynamic introduction of the process of treatment for the flocculation and flotation of fluid beds, all in a closed canal, wherein the flow of secondary streams (E) is dynamically and continuously submitted to flocculation and flotation techniques in an induced flow canal (FE) in the water treatment station.
