A comparison of rotating and stationary membrane disk filters using computational fluid dynamics


Journal Article

For given values of the flow rate and RPM, stationary membrane disk filters require less power input. Rotating membrane disk filters produce a higher shear stress on the membrane surface which may reduce fouling but may also result in a reversed flow of permeate due to the 'back pressure' induced by centrifugal force on fluid within the membrane disk. Operating conditions and design parameters should be selected to minimize this 'back pressure' phenomenon and maximize the effective membrane available for filtration.
