Abstract
An apparatus and method for treating sewage The apparatus receives sewage at a receiving compartment and separates solids from liquids at the receiving compartment. The solids can be extracted from the receiving compartment by an auger. The liquid sewage flows through a series of treatment compartment containing rotating biological contactor discs for treatment by these rotating biological contactor discs. The rotating biological contactor discs are secured to a rotating shaft. The rotating shaft and the auger are powered by a quasi-submerged turbine displaced by a flow of air.
