Permeate Flux in Ultrafiltration Membrane: A Review

open access: yesJournal of Applied Membrane Science & Technology, 2017
Membrane processes exist for most of the fluid separations encountered in industry. The most widely used is membrane ultrafiltration, pressure driven process which is capable of separating particles in the approximate size range of 0.001 to 0.1 μm. The design of membrane separation processes, like all other processes, requires quantitative expressions ...

Numerical simulation of colloidal dispersion filtration: description of critical flux and comparison with experimental results [PDF]

open access: yes, 2005
During filtration via membrane processes, colloids accumulate at the porous surface leading to fouling phenomena. In this study, a rigorous simulation of momentum and mass transfer using CFD modelling has been developed to describe such an accumulation ...

Integrally skinned polysulfone hollow fiber membranes for pervaporation [PDF]

open access: yes, 1994
From polysulfone as polymer, integrally skinned hollow fiber membranes with a defect-free top layer have been spun. The spinning process described here differs from the traditional dry-wet spinning process where the fiber enters the coagulation bath ...

Reversibility of fouling on ultrafiltration membrane by backwashing and chemical cleaning: differences in organic fractions behaviour [PDF]

open access: yes, 2016
Membrane fouling is an inherent phenomenon in ultrafiltration (UF) membrane processes, making it necessary to periodically perform backwashes (BW) and chemical cleanings in place (CIP) to restore the initial permeability of the membrane. The objective of
