Description:
The major objective of this study was to operate a full scale rotating biological contactor (RBC) to determine if it could produce an effluent that would meet the definition of a secondary effluent (BOD <30 mg/l; TSS <30 mg/l). An additional objective was to compare the performance and effluent quality of a RBC system with a full scale trickling filter operating in a parallel mode on the same influent wastewater. A secondary objective was to evaluate the effectiveness of chemical addition (alum and ferric chloride) to remove phosphorus and determine its effect on operating performance. The following results were determined from these studies. (1) The effluent from the RBC process met and exceeded the standards for secondary treatment. (2) The RBC process gave a superior effluent quality in regard to BOD and TSS than the trickling filter. (3) Chemical addition to the RBC process was effective for removing phosphorus. (4) Chemical addition in the RBC process showed a deleterious effect on BOD and TSS removal.
