Abstract: A solids removal system for use in removing sand and silt from well production fluids. The system has a manifold assembly provided with jetting nozzles, which is installed in a liquid and solids-containing vessel, where solids have settled in the walls. The jetting nozzles deliver, in a pre-determined sequence, a solids-dislodging fluid, causing the solids to become suspended in the fluid. The dislodged solids and fluid are then extracted by pump from the vessel and directed to a solid-fluid separator. Solids-free fluid is returned for re-re-circulation through the vessel, while the solids are moved to a containment location.
