ABSTRACT:
An immersion percolating filter arrangement for biologically purifying sewage effluent which is provided with growth accumulation surfaces adapted to be slowly rotated about an axis of rotation whereby the surfaces are alternately immersed in the sewage effluent and removed therefrom so as to enrich the biological growth accumulated thereon with oxygen. The growth accumulation surfaces are formed from a flexible material which are suspended under tension in planes parallel to one another within a roller cage support structure having end faces which are substantially circular. The end faces of the roller cage support structure are each provided with a bearing arrangement for permitting the rotation of the support structure about the axis of rotation with one of the bearing arrangements being connected to a suitable driving source. The end faces of the roller cage support structure are provided with radial support arms with the free ends of the arms being connected by a rigid connection member extending parallel to the axis of rotation for supporting the flexible material.
