Abstract | The rapid emergence of rotating biological contactor (RBC) technology as an alternative secondary wastewater treatment process has increased the need to review their performance history to provide information to the design engineer. This study, to review and compare current design procedures with field performance, was accomplished by a review of the literature; evaluation of process theory and system characteristics; field survey of plants at or near design flows for process and equipment performance, O&M requirements, and power requirements; and a comparison of design expectations with empirical performance. Equipment performance, centering on shaft failures and media deterioration, was found to be a problem. Process performance was hampered due to oxygen limitation primarily in the first stage, due to organic overloading. For the range of conditions found at the plants surveyed, process performance did not meet design predictions for percent BOD removal or mass BOD removal. |
