Abstract
Cleaning assemblies and particulate tolerant fluid bearings that are particularly well suited for use in centrifugal separation enhanced filtration devices are described. In one aspect of the invention, at least one bearing is arranged to carry a circulating cleaning assembly such that the cleaning assembly can rotate around a filter membrane during filtering operation of the filtration device. The bearing is preferably arranged to maintain the circulating cleaning assembly in a substantially coaxial alignment with the filter membrane and in a substantially stable longitudinal position relative to the filter membrane as the circulating cleaning assembly is rotated around the filter membrane. In another aspect of the invention a variety of particulate tolerant bearings are described.
