The tank can have a tubular ring positioned inside the tank adjacent the periphery of the bottom, a pipe communicating with the ring and the exterior of the tank for supplying fluid to the ring, and a plurality of holes in the ring from which fluid under pressure can be ejected along the slope of the bottom to wash solids to the conduit in the bottom for removal.
