Abstract
A feedwell design for a clarifier that may better dissipate the entrance energy of feed slurry liquid exiting the feedwell and entering the clarifier. Plates having a surface area twisted around a longitudinal axis may be provided at the bottom of the feedwell. The plates may cause a change in the flow direction of the feed, from being 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. Likewise, this may improve the rate at which solids settle out of the feed slurry solution, and thus improve the clarity of the removed liquid.
