Abstract:
A dynamic swirl filter assembly comprising: a housing; a processing fluid inlet arranged to direct process fluid into the housing;a permeate outlet arranged to direct permeate from the housing; at least one stationary filter element mounted in the housing and including a filter having a first surface communicating with the process fluid inlet and a second surface communicating with the permeate outlet; and a rotatable wall mounted around the stationary filter element and defining an axis of rotation, wherein the first surface of the filter is generally perpendicular to the axis of rotation, wherein the rotatable wall is substantially free of structure which extends substantially across a surface of the filter element, and wherein the rotatable wall is arranged to rotate the process fluid across the first surface of the filter, thereby creating a shear boundary layer at the first surface of the filter.
