Permeate Flux in Crossflow Ultrafiltration Under Intermediate Pressures
Journal of Colloid and Interface Science, 1999 The intermediate pressure range stands for an important condition for ultrafiltration operations where permeate flux falls below that predicted from a linear flux-pressure relationship but does not reach the limiting flux. Optimal performance of ultrafiltration might be achieved on the upper end of the intermediate pressure range because the maximum ...

Decline of Permeate Flux for Ultrafiltration Along Membrane Tubes
Desalination, 2002 The decline of permeate flux for ultrafiltration along membrane tubes was predicted from mass and momentum balances, based on the resistance-in-series model coupled with the considerations of the declinations of flow rate and transmembrane pressure along the membrane tubes.

, 2021 In any membrane filtration, the prediction of permeate flux is critical to calculate the membrane surface required, which is an essential parameter for scaling-up, equipment sizing, and cost determination. Permeate flux prediction is an essential parameter in membrane performance evaluation and the projections for scaling-up from laboratory to the ...

Fouling Layer Surface Heterogeneity Improves Permeate Flux
Proceedings of the Water Environment Federation, 2013 In this research, we used modeling to assess the impact of irregular fouling-layer surface morphology (i.e., roughness) on permeate fluxes. Two membrane filtration models, each based on Darcy's Law, were used to predict fluxes for fouling layers with varying degrees of surface irregularity.

Prediction of Permeate Flux and Permeate Concentration in Nanofiltration of Dye Solution
Separation and Purification Technology, 2004Abstract Unstirred batch and cross flow nanofiltration have been carried out to separate dye from aqueous solution. The effect of different process parameters on separation of dye is studied. Experiments are conducted with aqueous solution of crystal violet (CV, molecular weight 408) using a 400 molecular weight cut-off membrane.

Pressure-Dependent Permeate Flux in Ultra- and Microfiltration
Journal of Environmental Engineering, 2000 The effect of applied pressure on the permeate flux in cross-flow ultrafiltration (UF) and microfiltration (MF) was investigated both theoretically and experimentally. In UF and MF processes, the permeate fluxes are controlled by concentration polarization and cake formation over the membrane surface.

Effects of Ozonation on the Permeate Flux of Nanocrystalline Ceramic Membranes
Water Research, 2005Titania membranes, with a molecular weight cut-off of 15 kD were used in an ozonation/membrane system that was fed with water from Lake Lansing, which had been pre-filtered through a 0.45 microm glass fiber filter. The application of ozone gas prior to filtration resulted in significant decreases in membrane fouling.

Analysis of the slip effect on the permeate flux in membrane ultrafiltration
Journal of Membrane Science, 1999 A method for predicting the mass transfer coefficient as well as the limiting permeate flux in membrane ultrafiltration has been found, based upon the boundary-layer theory which takes into account the slip velocity on the membrane surface. The theory presupposes the existence of a slip flow on a porous membrane surface, especially for the limiting ...

Permeate Flux and Fouling Resistance in Ultrafiltration of Depectinized Apple Juice Using Ceramic Membranes [PDF]
Journal of Food Engineering, 2003 Raw depectinized apple juice was clarified in a laboratory scale ultrafiltration system using ceramic tubular membranes (Tech-Sep Carbosep) with a molecular weight cut-off of 300,000, 50,000, and 30,000 Da.
