ABSTRACT:
Improved fabricated subcomponents, components and rotating biological contactor embodiments that are assembled from, and that incorporate, such subcomponents and components are achieved. The components comprise tank sections, bulkheads, contactor drums, paddle wheels, shaft assemblies including associated bearings and supports, each of which may be assembled from preformed subcomponents if desired. Rotating biological contactors are assemblable at an installation site, which may be a confined space if desired, by two men with simple tools. In an assembled rotating biological contactor, the shaft assemblies can rotated by an electric motor, by fluidic pressure exerted upon paddle wheel blades, or by both in combination.
