<p>A biological wastewater treatment apparatus is disclosed in which a rotating biological contactor mounted on a horizontal shaft supported on a treatment tank has a plurality of pockets arrayed along the length of the contactor and at the outer periphery thereof. A gas conduit having a plurality of openings is disposed within the treatment tank and beneath submerged open pockets on the contactor. Air is admitted under pressure into the conduit and expelled through the openings. As the air rises to the surface it will be trapped in the pockets and cause the contactor assembly to rotate.</p> |
