Abstract
A clarification device for solids-liquid separation by gravitational settling has a peripheral inlet trough connected to a plurality of uniformly spaced inlet conduits which direct influent liquid and solids toward the center of the clarifier. The size of the hole in the inlet trough communicating with each inlet conduit can be selectively controlled and individually changed. This enables the volume of liquid and solids withdrawn through each hole to be controlled so as to cause the velocity energy decrease at each hole to generally equal the friction energy loss between any hole and the preceding hole while maintaining about the same volume of discharge flow into the clarifier through each inlet conduit.
