Rotating Biological Contactors (RBC) Systems

An efficient fixed-film wastewater technology well suited for secondary and/or advanced biological treatment

The RBC attached growth process consists of a large disc with radial and concentric passages rotating in a concrete or steel tank. 40% of the media surface area provided for biological growth is submerged in the wastewater. The 12 foot diameter unit rotates every 40 seconds. The frequent rotation into the wastewater and subsequent exposure to atmospheric oxygen delivers the food, oxygen and mixing needed for attached growth organisms to multiply and thrive. This large, active population causes the biological degradation of organic pollutants. Excess biomass shears off at a steady rate and is carried through the system for removal in a clarifier.
