Effects of operating parameters on fouling mechanism and membrane flux in cross-flow microfiltration of whey
TL;DR: In this paper, the effect of operating conditions on the degradation of permeate flux in cross-flow microfiltration of whey at constant operating pressure was investigated using linear forms of classic models as well as two-phase combined fouling models.
Journal ArticleDOI
A combined network model for membrane fouling
TL;DR: A network model for membrane fouling is derived that accounts for the inter-relation between fouling mechanisms and elucidates the concave-downward Q^V^ signature for multiple interactive fouling Mechanisms, able to identify the dominant fouling modality at each stage, and is able to provide insight into selecting appropriate operating regimes.
Journal ArticleDOI
Membrane fouling in microfiltration of oil-in-water emulsions; a comparison between constant pressure blocking laws and genetic programming (GP) model
TL;DR: In this paper, the performance of both blocking laws and genetic programming model was evaluated to determine if they would provide acceptable fits of the experimental data, and the best predictions were obtained by the intermediate model and the cake model.
Journal ArticleDOI
Fouling behavior and performance of microfiltration membranes for whey treatment in steady and unsteady-state conditions
TL;DR: In this paper, the effects of the operating pressure and crossflow velocity on the membrane performance and individual resistances in microfiltration of whey for both unsteady and steady-state conditions were investigated for two 0.45 µm mean pore size polymeric membranes, Polyethersulfone (PES) and Polyvinylidene fluoride (PVDF).

Fouling mechanisms of Pseudomonas putida on PES microfiltration membranes
TL;DR: In this article, the authors studied the mechanisms by which Pseudomonas putida causes fouling on a microfiltration membrane and showed that the selection of a high TMP had no effect on the final permeate flux but provoked an increase in external fouling.

Properties of microfiltration membranes: Flux loss during constant pressure permeation of bovine serum albumin
W. Richard Bowen,Quan Gan +1 more
TL;DR: An experimental study of permeation of dilute BSA solutions (filtration) at microfiltration membranes has been carried out, finding this phenomenon is quite different to adsorption of protein at such surfaces, this latter giving only sub‐monolayer or monolayer protein coverage under the conditions studied.

Cake resistance and solute rejection in bacterial microfiltration: The role of the extracellular matrix
TL;DR: The mechanism by which cake resistance and solute rejection occurs was shown to depend on the extracellular matrix of the organisms and the implications for future studies on crossflow microfiltration of biomass and biofluids are significant.
