Abstract

A cylindrical tank is divided by circular walls into three concentric spaces. The outer ring has an upper pre-treatment space and a lower sludge collection tank. The inner ring is the main activating/freshening space and the central section is the final sedimentation space. The chambers are interconnected to allow free circulation and a common drive shaft carries rotary aerations for the outer and inner rings and paddle type extraction pumps for sludge from the base and floating matter from the top of the central chamber both of which are fed back into the outer ring.
