A Rotating Biological Contactor (RBC) was constructed on a bypass of a portion of the combined sewerage in Milwaukee, WI., to demonstrate the feasibility of treating combined sewer overflows. Prior to actual field testing of this full scale RBC unit, simulated overflow tests were conducted with a bench scale RBC system to establish scale-up criteria for costing out the full scale plant, operating parameters and test conditions for the demonstration facility. Construction of the demonstration plant was completed early in 1969, and a full year of testing was completed in March of 1970. Average dry weather flow through the plant was 35 gallons per minute.
