Abstract
A high strength wastewater treatment system having a first tank with an inlet and an outlet, an aerator positioned within the first tank for passing oxygen into wastewater within the first tank, a second tank having a clarifier compartment positioned therein, an aeration device positioned in the second tank for passing oxygen into a liquid within the second tank, and a pipe connected to the first tank and the second tank for passing liquid from the second tank to the first tank. The second is interconnected to the outlet of the first tank. The second tank has an outlet extending from the clarifier compartment. In particular, the pipe has an end opening within the second tank and a diffuser connected to the pipe within the first tank. The diffuser is a venturi diffuser having a narrow section and a wide section. An air pump is connected to the venturi diffuser for injecting air into the narrow section. This delivery of air serves to draw liquid from the second tank through the pipe and into the first tank. The end of the pipe opens below the clarifier compartment in the second tank.
