Waste water treatment rotating aeration drum has series of sickle-shaped baffles for resident micro-organisms, combines efficiency with easy installation

A waste water treatment assembly aerates water within a narrow vertical drum containing a colony of resident micro-biological organisms on the inner surfaces. The drum rotates on an axle at its mid-point. The circular chamber within the drum has a regular series of radial baffle plates linking the facing side-walls. In cross section, each baffle plate is sickle-shaped and has at its center a smaller semi-circular baffle plate, from which it is separated by a gap. The drum has inlets and outlets for air and water. A bank of such drums may be set up upon a common power-driven axle. Zur aeroben Behandlung von Abwasser und flüssigen organischen Abfällen sind zwischen den Scheiben eines aus Scheiben bestehenden, auf einer angetriebenen Welle in einem Behälter umlaufenden Rotationskörpers halbkreisförmig gebogene Schaufeln zentral zur Achsmitte der Scheiben angeordnet.
