NOVELTY - An aerobic wastewater treatment system comprises a first tank adapted to partially treat wastewater; a second tank including a pump and control system; and a third tank containing an aerator and engineered filter media that facilitate and maintain microbial colonies that oxidize organic matter, retain solids, reduce nutrients, and inactivate pathogens to treat wastewater and discharge effluent which is clean of pollutants and pathogens.    USE - The aerobic wastewater treatment system is used for removing organic material and solids from wastewater. It is useful for residential or commercial environments.    ADVANTAGE - The system has high quality, is reliable, has low maintenance, and has improved operational performance. The system copes better with variations in wastewater flows than many prior art systems. It can remove over 99.999% of the pathogens. It promotes public health and environmental protection, and provides for the most efficient removal of organic material and solids from wastewater.    DETAILED DESCRIPTION - An aerobic wastewater treatment system (10) comprises a first tank (12) adapted to receive, mix and partially treat wastewater; second tank (14) adapted to hold wastewater, where the first tank discharges partially-treated wastewater to the second tank; and third tank (16) containing an aerator (58) and engineered filter media (44) that facilitate and maintain microbial colonies that oxidize organic matter, retain solids, reduce nutrients, and inactivate pathogens to treat wastewater and discharge effluent which is relatively clean of pollutants and pathogens. The second tank includes a pump and control system (38) operatively connected to the pump to control the frequency, interval, volume and rate of transfer of wastewater from the second tank to the third tank.
