Permeate flux improvement along a tubular ultrafiltration membrane

Desalination, 1988
Abstract Important research efforts are directed towards the study of the concentration polarisation in pressure-driven membrane processes at the upstream solution-membrane interface. Seldom, solute adsorption or retention are mentioned at the downstream permeate-membrane interface, except for dialysis processes.

Improving permeation flux by pulsed reverse osmosis

Chemical Engineering Science, 1974
Abstract Pulsed and nonpulsed reverse osmosis experiments were conducted with a sucrose solution in cylindrical cellulose acetate membranes. For pulsing frequencies up to 1 Hz, permeation increases of more than 70 per cent were observed. A simple quasisteady-state theory for concentration polarization based on a film model of mass transfer describes ...

Unsteady-State Permeate Flux of Crossflow Microfiltration

Separation Science and Technology, 1994
Abstract In this study a membrane filtration cell was installed to investigate the variation of permeate flux with filtration time under various operating conditions including crossflow velocity, pressure drop, particle concentration, membrane pore size, particle size, pH, and electrolyte concentration.

Permeate flux prediction

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 ...

Inorganic particles increase biofilm heterogeneity and enhance permeate flux

Water Research, 2014
This study investigated the influence of inorganic particles on the hydraulic resistance of biofilm grown on membrane surface during low-pressure dead-end ultrafiltration. Gravity-driven ultrafiltration membrane systems were operated during several weeks without any flushing or cleaning.

Permeation flux of hydrogen through plasma facing materials

Physical Review B, 1997
A general formula for simultaneous gas- and plasma-driven permeation of hydrogen (tritium) has been developed by an electrical circuit analog, in which the permeation potential and resistance are defined for both diffusion in the bulk and recombination on the surface and the gradient of permeation potential against permeation resistance is considered ...
