Abstract:
A random media member for a rotating biological contactor. The media member has a concave hemispherical shaped body with an inner tube with radial plate like ribs and an outer tube with radial plate like ribs, all molded together as an integral part. In one embodiment, a hollow cylinder is molded to the outside of the body. In another embodiment, parallel spaced legs are substituted for the outer cylinder. The tubes and ribs provide surfaces for bacteria to attach.
