Method and apparatus for aerobically treating wastewater

Patent ·
OSTI ID:6264892
Wastewater is directed into an aerobic treatment tank which is divided by a partition into an aeration chamber and a settling chamber. The waste material is aerated in the aeration chamber and then directed into the settling chamber. Any solids in the settling chamber settle out and are pumped back into the aeration chamber through a sludge return conduit wherein the returning sludge is saturated with air. The treated liquid is discharged to a drainage area in a colorless, odorless form. The pipes which direct the liquid through the tank are oriented to impede the passage of solids through the system, thereby keeping the solid wastes in the aeration chamber.
