ABSTRACT:
An wastewater treatment system is provided. The system includes a cylindrical tank having a sidewall, a bottom, an upper portion and a lower portion. A cone-shaped hopper, open at both ends, is positioned in the tank. The hopper's upper opening is larger than the lower opening. The system includes a compressed air source connected to at least five radially spaced air outlet pipes, each air outlet pipe being fluidly connected to the compressed air source and extending downward into the lower portion of the tank and having an open end positioned above the bottom between the hopper and the sidewall of the tank so as to discharge air into an aeration zone between the hopper and the tank sidewall; an inlet line connected to the tank and having a discharge end opening into the tank between the hopper and the tank sides; and an outlet line having an inlet end positioned within the hopper in the upper portion of the tank and an outlet end exterior of the tank, whereby the wastewater within the tank is continuously aerated through the air outlet pipes with a sufficient volume of air and sufficiently large bubbles such that the wastewater is continuously agitated within the tank exterior of the hopper so as to eliminate any quiescent zones in the upper portion of the tank.
