Final answer:
The Rotating Biological Contactor is a device used for wastewater treatment, involving discs that help decompose organic pollutants in the water. It's part of the secondary stage of a multi-step wastewater treatment process.
Step-by-step explanation:
A Rotating Biological Contactor (RBC) is a device used for wastewater treatment. It is an advanced secondary treatment process, which involves several large discs mounted on a rotating shaft that are partially submerged in wastewater. The biological growth (biofilm) on these discs absorbs, consumes, and breaks down organic pollutants as the discs rotate. RBCs are not involved in processes such as producing bacterial biomass with methanol as a substrate, producing yeast with oil as a substrate, making beer, wine, or antibiotics, nor are they related to medical imaging devices.
Instead, these devices are part of a complex process that may include various treatment stages such as primary (solid removal), secondary (bacterial decomposition), and tertiary (extra filtration). Large objects like plastic, which can damage wastewater treatment equipment, are removed from the wastewater by mechanical means such as a bar screen before reaching the RBC.The Rotating Biological Contactor (RBC) is a device used for wastewater treatment. It is a type of rotating machinery that utilizes biological processes to remove organic matter and pollutants from wastewater.
