ABSTRACT:
A process for separating solids from a fluid using at least one polymer and acoustic energy at or above cavitation is disclosed. The fluid containing the polymer is flowed into a vessel and acoustic energy is applied to the fluid at intensity sufficient to induce cavitation within the fluid. At least a portion of the solids are allowed to agglomerate in at least one position within the vessel. The agglomerated solids are then separated from the fluid.
