ABSTRACT:
In a sewage treatment system having a series of generally concentric, ring-like treatment tanks, a siphoning head used to withdraw sludge from the bottom of the clarifying tank is propelled slowly and smoothly through its tank by the moving current of sewage in an adjacent tank. Overhead bridge structure supporting the siphoning head in the clarifying tank also overhangs the next adjacent tank and supports a depending baffle which is impinged by the flowing sewage in the adjacent tank. The baffle is positioned closely adjacent the wall between the two tanks such that eddy currents set up in the vicinity of the baffle as the latter is acted upon by the flowing sewage have the effect of entering transfer passages between the two tanks to clean out clogging debris and grease.
