EnviroDisc RBC

EnviroDisc Rotating Biological Contactors (RBC) provide highly efficient fixed film BOD and ammonia removal with low energy usage and maintenance requirements. In the RBC process, wastewater flows through shallow tanks containing the partially submerged, rotating shafts where biomass is carried on the media for reduction of pollutants.

RBCThe EnviroDisc utilizes a framework to support the removable media. The shaft is a 30" diameter, 3/4" thick wall. This is the largest shaft available and is structurally superior to any other in the marketplace to provide a rugged design capable of an extended fatigue life. The EnviroDisc also utilizes either a direct or a shaft-mounted drive. Shafts are available in 11' 10" diameter, 26'0" nominal length, in both 100,000 square feet and 150,000 square feet media area, and also several shorter lengths for small plant applications.
