ABSTRACT:
A plurality of similar open-ended fluid conduits are interconnected between a like number of fluid volume zones within a fluid-filled vessel, such as a clarifier, having a steady upflowing fluid supply, and a small continuously draining collector box adjustably suspended from the top of the vessel and immersed a few inches below the fluid level. The conduits discharge into the collector box through orifices on which a common head is maintained, so as to draw down each fluid zone at the same rate. Thus, the collector box acts as a weir. The conduits are spaced so as to minimize the existence of channeling or lateral currents, which interfere with the most efficient settlement of solid matter. Orifice plates interconnected with the discharge ends of the conduits within the collection box are easily accessible through a hatch in the top of the covered vessel for cleaning, and adjustments.
