ABSTRACT:
A barriered pump/aerator, for continuously moving and aerating mixed liquor having translational-flow momentum within an endless channel of a barrier oxidation ditch, conserves at least a portion of the momentum by enabling induced flow of the mixed liquor past the barrier. In one embodiment, the induced flow passes through a discharge slot which contains a plurality of jet aerators. In another embodiment, the induced flow passes through a trough formed in the bottom of the endless channel past an inclined baffle. In a third embodiment, the induced flow passes through a tubular passage having a plurality of jet aerators disposed therein.
