Rotating Biological Contactors

Rotating Biological Contactors (RBCs) are a type of secondary treatment technology used in wastewater treatment. They consist of large discs or media that rotate slowly in the wastewater, providing a surface for microorganisms to grow and break down organic matter. As the discs rotate, they alternate between submerged and exposed to air, facilitating oxygen transfer and microbial activity. RBCs are efficient, compact, and can handle varying loads, making them suitable for municipal and industrial wastewater treatment applications.
