“…29 It was known that particle quantity transported from bulk uid to the dynamic layer surface would equal the quantity from the surface back to bulk uid when the steady permeate ux was achieved. [22][23][24] In an addition to the lateral migration, the shearinduced and Brownian diffusions were the two major mechanisms to govern this back transport, which were all in the opposite depositional direction. [29][30][31] Brownian diffusion favored the transport of smaller particles while the shear-induced diffusion increased as particle sizes increased.…”

“…Schulz and Ripperger, Hunt et al and Perkins et al developed their own similar models. [22][23][24] Before the permeate ux had been stabilized, the particle concentration, uid velocity and pressure varied along the radial direction; when the ux was stabilized, the particle quantity transported from the bulk stream to the membrane surface was equal to the quantity from the membrane surface back to the bulk stream. Based on classical mechanics, Blake et al proposed a force balance model by analyzing the forces exerting on a single particle deposited on the dynamic layer.…”
Theoretical and experimental investigations were conducted to predict particle deposition and layer growth during formation of a dynamic membrane using cross-flow microfiltration, good agreements were achieved between predictions and measured data.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
