A sludge digester comprises a mixing tank providing an integral ceiling, interior wall surface and a floor surface. A vertical beam supports a mixing device engaged for movement along the vertical beam. A plurality of sparger jets protrudes from the wall surface for delivering an oxygen gas flow directly into the interior of the sludge. A second plurality of sparger jets terminates at the mixing tank floor surface for delivering oxygen gas into the mixing tank and a plurality of bubbling diffusers protrudes upwardly from the floor surface for delivering further oxygen gas flow into the mixing tank.
