Abstract:
An improved apparatus for filtration has a fluid mixture feed comprising light and heavy fractions fed into the workspace between counter-rotating disk impellers within a tank, thereby forming vortices in the workspace. A static radial exhaust array is located axially in the workspace, comprising exhaust channels, each of which has a peripheral end facing the workspace and an inner end communicating with an axial exhaust drain. An axial pump produces low pressure in the axial exhaust drain, thereby drawing in and anchoring the vortices to the peripheral ends of the exhaust channels so that the exhaust channels can extract the contents of the vortex cores. Vanes can be incorporated into the workspace surface of each disk impeller so that the opposed vanes pass in close proximity, forming vortices along a plurality of radial lanes of intersection, with the peripheral openings of each of the exhaust channels aligned with at least one of the lanes of intersection in the workspace. The feed can be a peripheral feed which enters the workspace radially inward through the periphery of the workspace, or the feed can enter the workspace radially outward through a static axial feed array.
