ABSTRACT:
Operation of an intra-channel clarifier within a circulating sewage stream can be enhanced by flow adjusting vanes positioned within the sewage stream between the clarifier and channel wall, proximate to the clarifier sludge ports. In a preferred embodiment, the vanes are aligned perpendicular to the flow of the stream, on a vertical axis. The vanes are divided into an independently adjustable upper and lower portion which can be used to direct the sewage flow and alter the cross sectional area of the sewage stream in the vicinity of the clarifier. The rate at which sludge is removed from the clarifier is affected by the velocity of the sewage stream beneath the sludge ports as well as any turbulence or eddy currents which are produced.
