Abstract
Bio-oxidative treatment of aqueous waste by means of a partially submerged rotating biological contactor (or RBC) is improved by suffusing the rising submerged quadrant of an RBC with air furnished within the RBC perimeter. Air is distributed along and outward from the rotational axis and is released between discs of the RBC. Some of the air so released is trapped by protrusions on the discs. Rotation of such RBC is accomplished or at least aided by differential buoyancy imparted by such air suffusion and trapping.
