Abstract
A method of removing sediment from the bottom of a settling collects the sediment from the compressed Zone IV layer of sediment adjacent the floor of the settling tank. The process utilizes a fabricated metal sludge collection system having a central truck and a pair of triangularly shaped header wings extending laterally to each side of the central truck. The header wings have an open throat that allows the passage of the Zone IV sediment layer into the header wing, while the diagonally oriented, rearwardly extending side edges of the header wing have elastomeric sweeps attached to prevent the sediment from passing out of the header wing. The sweeps accumulate the sediment at the rearwardly trailing apex of the header wing where a pump extracts the accumulated sediment remotely from the settling tank. A T-connector is formed with a baffle to improve the discharge of sediment from the header wings.
