ABSTRACT:
A wastewater treatment system which comprises a tank having defined therein an aerobic treatment zone and a suspended micromedia zone. One embodiment further includes an anaerobic treatment zone. The suspended micromedia zone includes a separating media. Substantially continuous aeration is provided to energize the separating media and cause it to be stirred up into a water column within the tank. The air flow provides partial suspension of the separating media and imparts continual upward motion to the wastewater in such zone. A chimney is provided above a portion of the suspended micromedia zone and extends above the aerobic treatment zone. The mixed liquid and air rising due to the aerator air flow travels within the chimney into the aerobic treatment zone. Some separating media also travels within the chimney into the aerobic treatment zone. Aerobic bacteria is provided in the aerobic treatment zone external of the chimney. After percolating through the aerobic bacteria, the wastewater is returned back to the suspended micromedia zone. An underdrain zone receives water which has percolated downward through the suspended micromedia zone and has been thereby clarified. Underdrain zone is in fluid communication with a tank outlet.
