ABSTRACT:
A wastewater treatment plant comprising a pretreatment chamber, aeration chamber and a settling chamber designed to minimize or eliminate sludge buildup at the bottom of the aeration chamber. Two support walls are provided. The combined function of one support wall and an angular portion at the bottom of the common wall between the aeration and settling chamber is to regulate the flow pattern in the aeration chamber and return settled biodegradable matter from the bottom of the settling chamber to the aeration chamber for further treatment. The fluid flow created by the wall structure enhances the action of the settling chamber and elinates dead zones in the aeration chamber thus minimizing sludge buildup.
