Transient permeate flux analysis: model validation
An extended model integrating several particle back-transport theories has been proposed by Sethi and Wiesner to predict transient permeate flux as a function of operational parameters for constant permeate flux (CF) and constant transmembrane pressure (CP) cross-flow regimes.

Ultrafiltration to Increase the Consistency of Fruit Pulps: The Role of Permeate Flux [PDF]
Ultrafiltration is a well-known operation, widely used in food processing, especially to concentrate selectively liquid compounds. However, so far, it has been mainly used to change concentration and/or clarify liquids with low viscosity. Ultrafiltration

Steady-state permeate flux of crossflow ceramic microfiltration
This paper deals with both theoretical and experimental studies of the ceramic microfiltration of dilute model suspensions. Steady-state permeate fluxes were analyzed and a simple model based on the critical flow velocity theory has been developed and tested in this study.

Oxygen permeation in bismuth-based materials. Part I: Sintering and oxygen permeation fluxes [PDF]
Oxygen permeation measurements were performed on two layered bismuth based oxide ceramics: a rhombohedral phase belonging to the Bi2O3-CaO system, (Bi2O3)0.73- (CaO)0.27 (BICAO) and a BICOVOX phase. Oxygen permeability for these systems was compared to permeability of the cubic fluorite type structure with composition (Bi2O3)0.75(Er2O3)0.25 (BE25). Low
