A combined sewer overflow regulator which by induced hydraulic conditions separates settleable and floatable solids from the overflow was studied. A mathematical model was also prepared to determine a basis for design. The study also used a hydraulic model to determine swirl concentrator configurations, flow patterns and settleable solid removal efficiency. Excellent correlation was found between the two studies. It was found that at flows which simulate American experience a vortex flow pattern was not effective. However, when flows were restricted, a swirl action occurred and settleable solids were concentrated in the outflow to the interceptor in a flow of two to three percent as compared to the quantity of overflow through a central weir and down shaft. The swirl concentrator appears to offer a combined sewer overflow regulator that effectively regulates the flow and improves the quality of the overflow, with few moving parts.
