Abstract
Apparatus for cleaning sediment from basins comprises a suction system that withdraws particulate-laden liquid from the bottom of the basin. A pump providing the suction transports the particulate-laden liquid to a first vessel or catch tank where primary settling of the particulate can occur. A second pump withdraws particulate laden liquid from the catch tank and directs a high velocity flow of particulate laden coolant through separator apparatus for primary separation of particulate matter. The discharge of effluvia of the primary separator is conducted to a second vessel or tank. A third pump withdraws liquid from the lowermost portion of the second vessel and forces a high velocity flow through a secondary system for further separation of particulate matter from the liquid. The discharge of the second separator system is conducted to a third vessel or tank. A fourth pump withdraws liquid from the bottom of the third vessel and forces a high velocity flow through a tertiary separator system for yet further separation of particulate matter from the liquid. The discharge from the tertiary separator is conducted to a fourth vessel. A fifth pump withdraws cleaned liquid from the lowermost portion of the fourth vessel and conducts the cleaned liquid back to the basin.
