ABSTRACT:
A turbulence control system is provided comprising a first baffle, fixedly connected across the interior of an intra-channel clarifier having side walls between the side walls near the point of entry of wastewater into the clarifier, the first baffle covering a desired portion of the cross-sectional flow area within the clairifier; and a second baffle, fixedly connected across the interior of the clarifier between the side walls downstream of the first baffle and covering a desired portion of the cross-sectional flow area left uncovered by the first baffle. The turbulence control system may also comprise at least one accumulation baffle, connected between the side walls and near the bottom of the clarifier, the accumulation baffle extending upward to a desired height within the clarifier, but not so high as to produce a flow velocity which would impede settlement of sludge within the clarifier. Another possible feature of the turbulence control system comprises at least one guide vane, fixedly attached to the clarifier beneath its bottom and running parallel to the length of the clarifier. The turbulance control system may also comprise a pair of hinged wings mounted to the bow of the clarifier.
