ABSTRACT:
A rotary biological contactor for treating waste water comprising a center core or shaft and a plastic media on the shaft and arranged in a multiplicity of modules spaced from each other, each module including a multiplicity of turns of plastic sheet material with edges at the ends of the module, the turns of plastic sheet material having elongate undulations extending obliquely of the rotation axis and of the ends of the module, adjacent turns of the plastic sheet material having the undulations extending transversely of each other so that each elongate undulation traverses a multiplicity of undulations of the next adjacent turn, each undulation being welded to the undulations of the next adjacent turn at each place where the undulations touch each other, and the plastic sheet material also having circumferentially extending zones or bands traversing the undulations and extending transversely of the undulations, the bands being free of such undulating relationship, the several undulations and circumferential bands defining a multiplicity of flow channels extending in multi-oblique directions and circumferential directions for alternately filling and purging the air and water during each revolution of the module and shaft.
