The slurry flows out through the open bottom of the vertical pipe to the upper portion of the tank outside the vertical pipe. At least some of the liquid portion of the slurry rises through the sedimented mud of the slurry and collects in the upper portion of the tank outside the vertical pipe above the level of the tank outside the vertical pipe above the level of the mud. Some of the slurry flows downwardly through the passageway between the tray and the tank into the lower portion of the tank.
