ABSTRACT:
This invention relates to the ultrasound enhancement of sedimentation of particulates in a particulate-bearing fluid medium while the fluid medium is undergoing centrifugation. The ultrasound energy forms standing waves in the fluid and cause particulates in the fluid, whether solids, liquids, or gases, to agglomerate in bands. The bands approximate either the nodes or antinodes of the standing wave, depending on the density of the particulate relative to the fluid. The banded or agglomerated particulate enhances the rate of sedimentation as well as the reverse flow of suspernatent by removing particulate which would otherwise impede this flow.
