ABSTRACT:
The energy of liquid and solids flowing in a basin toward a clarifier section is substantially reduced before the liquid and solids enter the clarifier section. The basin is provided with an inlet wall having an inlet opening adjacent the top thereof. A sheet having an arcuate, reverse "C" shape is mounted across the inlet opening with the open side of the "C" facing the inlet wall to receive the liquid and the solids therefrom. The sheet causes the liquid and the solids to flow in two helical paths toward opposite side walls of the basin, which flow dissipates some of the original kinetic energy of the inlet liquid and solids. The helically flowing paths of liquid and solids are discharged into the basin spaced from the side walls of the basin, which further dissipates some of the kinetic energy of the liquid and the solids. The discharged liquid and solids flow into a top of manifolds along side walls with low velocity, but with sufficient remaining kinetic energy to flow along such top, and gradually toward the bottom of the basin for entry at very low velocity into the clarifier section without forming a hydraulic jump at the ends of the manifold and with minimum disturbance of the solids-settling action of the clarifier.
