ABSTRACT:
A flow-through medium for use in a biological digester has a truncated conical shape, a plurality of internal ribs, and optional external ribs. The conical shape of the media creates a venturi-like action for fluid flowing through the media, which increases the tumbling of the media elements against each other and against the wall of the enclosure in which they are contained. Moreover, the conical shape and venturi-like action prevents slough from accumulating within the media elements, allowing it to be washed through the media.A method of treating sewage effluent includes placing the media elements in an enclosure partially submersed in the effluent and rotating the enclosure to expose the media to the effluent and to a source of oxygen.
