Rotating biological contactors (RBC), also called rotating biological filters, are fixed bed reactors consisting of stacks of rotating disks mounted on a horizontal shaft that are partially submerged in a reactor and rotated as wastewater flows through. They are used in conventional wastewater treatment plants as secondary treatment after primary sedimentation of domestic grey- or blackwater or any other biodegradable effluent. The microbial community is alternately exposed to the atmosphere and the wastewater allowing both, aeration and assimilation of dissolved organic pollutants and nutrients for their degradation.
