ABSTRACT:
An apparatus for final clearing of waste water in a settling tank includes an inverted conical collecting basin having openings in the walls thereof. An annular air chamber encircles and is attached to the upper edge of the basin and floats in the waste water. Waste water enters the collecting basin through the openings therein and sludge in the water settles to the bottom of the basin. The cleared water at the top of the basin flows into an overflow receptacle and is removed therefrom by a pipeline. The sludge at the bottom of the basin is conveyed upwardly by a conveying device through a conveying pipe to a collecting receptacle and is removed therefrom by a pipeline.
