Cross-flow ultrafiltration

Membrane fouling is universally accepted as one of the critical problems limiting the wider application of membranes in liquid–solid separation. The in-situ ultrasonic application is one of the promising methods for reducing the extent of concentration polarization and increasing permeate flux durin

This paper aims to examine the separation of ultrafine titanium dioxide (TiO2) ptotocatalyst from its aqueous suspensions and its reuse by cross-flow ultrafiltration (CFU) process. Initially, the effects of various parameters, such as feed concentration, transmembrane pressure, cross-flow velocity,

This work deals with cross-flow ultrafiltration of highly viscous liquids. Several years ago a few attempts were made to decrease viscosity by either using high temperatures or adding chemicals. But these alternatives present significant drawbacks: high additional costs in terms of equipment or ener
