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.
Claims6
A process for separating fine solids from an aqueous fluid containing at least one polymer;
- said process comprising the steps of:
- flowing said fluid into a vessel;
- applying acoustic energy in said fluid within said vessel at an intensity sufficient to induce cavitation within said fluid;
- and
- allowing at least a portion of said fine solids to agglomerate in at least one position within said vessel;
- separating said agglomerated solids from said fluid.
