ABSTRACT:
An improved collector hood for a sedimentation tank. The collector hood is disposed within the tank and separates the tank into an upper reaction compartment and a lower settling compartment. The collector hood has the shape of an inverted funnel including a tubular upper portion connected to an outlet in the sidewall of the upper reaction compartment and a downwardly diverging conical wall lower portion, the periphery of which engages the sidewall of the tank for separating the tank into the upper reaction compartment and the lower settling compartment. A plurality of downcomer pipes are arranged around the axis of the collector hood and depend from the downwardly diverging conical wall into the lower settling compartment. The downcomer pipes provide multiple paths for the incoming liquid mixture to pass through the downwardly diverging conical wall of the collector hood to the lower settling compartment of the tank whereby the particulate matter in the liquid mixture settles to the bottom of the tank and clear treated liquid rises to the interior of the collector hood to enter the tubular portion of the funnel and leaves the tank through the outlet in the sidewall thereof.
