Abstract
The objectives of this study were to investigate the flocculation/flotation characteristics of combined sewer overflow through laboratory and field testing. The concept involves the introduction of chemicals and buoyant flotation aids into the overflow and the subsequent coflocculation of the suspended sewage solids about the aids which rise to the surface from where they may be removed by skimming. Recovery, cleaning and reuse of the flotation aids was judged essential to economic feasibility for the flocculation/flotation process. This deficiency, coupled with the overall mechanical complexity of the process, resulted in the investigation concluding that the flocculation/flotation process is not as promising for broad field application to the storm overflow problem as the similar dissolved air flotation process.
