ABSTRACT:
An apparatus to separate solids from drilling slurry, having an inlet positioned over an outlet of a concentration tank to displace water that would otherwise enter the down-stream centrifuges. Baffles are provided to direct solids to the outlet and minimize the time that solids spend in the concentration tank. Fluids having solids removed therefrom are removed from the apparatus at a location remote from the outlet.
