| Contents Notes |
"This study investigates the performance and operating histories of rotating biological contactors (RBC's) used for secondary wastewater treatment. Site visits and contacts with plant operators were undertaken to provide data for design engineers concerned with improving these systems. Plants surveyed complied better with effluent requirements than with BOD removal standards. Unacceptable performance was traced to organic overloading or underloading. Equipment performance is the most severe limitation currently facing RBC systems, with component failures prevalent in equipment from all suppliers. Cumulative RBC performance in terms of BOD removal fell below the manufacturers' design recommendations. Dissolved oxygen limiting conditions were the most significant RBC performance problem. Costs of operating RBC units were less than those for activated sludge systems and more than those for trickling filters." |
