ABSTRACT:
An apparatus for the aerobic, sludge-free decompositon of sewage and the like, includes a plurality of separate, liquid filled compartments, one of the compartments having a rotatable, air-operated, horizontally disposed perforated drum therein in which raw sewage is placed. Air inlets are at the bottom of the compartment, and air bubbles flowing upwardly therefrom cause the drum to rotate, to thus break up and fragment the raw sewage therein until the particles thereof are of a size such as to pass through the perforated wall of the drum into the compartment. The fragmented sewage is further agitated in the compartment and thoroughly aerated, whereby aerobic decomposition thereof rapidly takes place. The material is then passed sequentially through all of the compartments and recycled as necessary, until substantially complete liquification and decomposition thereof is accomplished.
