摘要： The injection of oxygen to a flotation basin in the process of removing pollutants from water streams of the type comprising the steps of: applying a flocculating or coagulating agent that are quickly mixed with each other (1) to a portion of the water stream to be treated; creating a flocculation basin along said water stream so that suspended particles may aggregate upstream same, thus generating larger flakes. The injection of oxygen consists of submitting said aggregate particles with higher dimension and density located upstream said portion of the water stream to at least one step of dissolving and injecting oxygen from a concentration plant (5), then directing same to dissolving plants through pressurized mixers (3), thus forming a water/oxygen mixture to be injected to portions (6) of the water stream, causing said aggregate particles to float; creating a flotation basin along said portion of the water stream so that the floated material may agglomerate upstream same, said floated and agglomerated material that is present upstream on the surface and by the banks of the water stream being removed by scraping the surface of the water stream.
