Title: Dynamic swirl filter assemblies and methods

Abstract: A dynamic swirl filter assembly having a rotatable filter housing for applying a fluid sheer layer to the surface of the filters therein to enhance filtration. The dynamic swirl filter assembly utilizes a rotatable filter housing to provide a fluid shear boundary layer immediately adjacent the surfaces of a plurality of stationary disc type filtering elements. The fluid shear boundary layer generates lift, thereby preventing particulate and/or colloidal matter of a given size from contacting the surface of the plurality of stationary disc type filter elements.
