Rotating Biological Contactor Diagram. Simplified schematic of rotating biological contactor. New developments in plastic media material as well as smaller energy requirements compared to activated sludge processes led to the construction of numerous rbc plants during the 1970s.

Rotating biological contactors and physical chemical processes metcalf and eddy 1991. Schematic diagram of a typical rotating biological contactor rbc.
Rotating biological contactors rbc are a conventional aerobic biological wastewater treatment unit.
Rotating bilogical contactors rbc 1. 2 trickling filters. The rotating biological contactor rbc is a fixed film biological secondary treatment device in operation a media consisting of a series of circular disks mounted side by side on a common shaft is rotated through the waste water flow. During the treatment process microbes that remove the organic material in the wastewater by using the organic material as a food source attach themselves to the disc surfaces.
