Abstract: Certain examples relate to a new feedwell design for use in a clarifier that may better dissipate the entrance energy of the slurry-liquid combination exiting the feedwell and entering the clarifier. Plates of various shapes may be provided proximate to the bottom of the feedwell. The plates may cause a change in the flow direction of the feed, from mostly horizontal to mostly vertical, to slow the slurry. The provision of plates at the bottom of a feedwell in a clarifier may advantageously reduce the velocity of the materials entering the clarifier, or may increase the uniformity of the flow rate of the materials; while reducing or maintaining the amount of shear force, turbulence, or other forces that may have a detrimental effect on clarification. This may, in turn, permit solids to better “settle out” of the slurry-liquid combination, and thus improve the clarity of the removed liquid.
