| Abstract |
The primary objective of this project was to evaluate the impact of flow equalization on the 0.092 cu m/sec (2.1 mgd) activated sludge plant at Walled Lake/Novi, Michigan. Process streams were characterized for a twelve-month period under equalized flow conditions with respect to BOD, total suspended solids and total phosphorus. The effects of the equalization basin on final settling and filtration were evaluated by conducting two intensive week-long studies, one with and one without equalization of flow. Flow equalization was effective in leveling influent flow variations but had very little effect upon concentration leveling. Performance of the multimedia filters was superior under the equalized flow, both in terms of average removal efficiency and consistency. |
