摘要： An aerobiotic sewage disposal system including a primary comminution or break up chamber wherein gross incoming solids are broken up and partially oxidized as they pass within a fiberglass cone with the bottom of this conical hopper having a circular aerator positioned so as to provide only a thin annular passage so that only minute solid particles may escape the cone compartment after being reduced in size through aerobic action. The secondary treatment is strained through a filter placed around the conical hopper so that , by aerobic action, the biological filtering can be completed. This filter bag is formed of a ''''sandwich'''' of polyester deep pile inner lining with a center of activated charcoal and a outer polyester cloth. The second aerator is placed around the bottom surface of the unit, with the bottom wall of the unit being convex so that minute suspended solids which may pass through the filter bag, would tend to settle around the bottom edge of the unit, and would be agitated by the aerator which is in the lowermost corners of the unit and prevents any accumulation of sludge. A third filter is provided for completing filtration with a weir type pick up being provided for collecting the effluent.
