 DensaDeg is a high rate solids contact process designed by Infilco-Degremont (IDI), which can operate at clarification rates up to 16 gpm/ft2, as piloted during Foundation Project # 3114. Clarification rates for this system are based on flow per square foot area occupied by the tube settlers at the top of the clarification basin. A loading rate defined in this manner does not account for the increased footprint due to remainder of the system's components. This process typically includes a rapid mix module, solids contact in the "reactor" zone following rapid mix, and separation of liquid phase and thickening of solids phase in the "clarification/thickening" zone. Thickened solids from the clarifier zone are recirculated back into the reactor zone, and the mixer in the reactor promotes solids contact opportunities for the incoming solids in the untreated water along with recirculated solids from the clarification zone. The rapid mix module is normally used in other studies, but was not used in this study. Characteristics of the DensaDeg system demonstrated during this study include: Process Schematic (Provided by Infilco Degremont, September 2007) View Typical System Drawings (Provided by Infilco Degremont, September 2007) |
