Treatment of dye solutions by vacuum membrane distillation

Water Research, 2008
In this work, the vacuum membrane distillation (VMD) process has been applied to treat water containing different types of dyes. The influence of operating parameters, as feed temperature, feed flow rate, feed concentration, on the permeate flux and on rejection has been investigated.

Membrane distillation. I. Module design and performance evaluation using vacuum membrane distillation

Journal of Membrane Science, 1996
Pure water vacuum membrane distillation (VMD) experiments were performed to evaluate the heat and mass transfer boundary layer resistances in a new laboratory-scale membrane module. The membrane module designed for this work is unique in that it can use flat-sheet membranes without a support.

Separation efficiency in vacuum membrane distillation

Journal of Membrane Science, 1992
Abstract Vacuum membrane distillation has been analyzed as a separation process for aqueous mixtures. The total permeate flux obtained is affected by two simultaneous resistances, those due to the heat and mass transfer processes which take place through the liquid phase and through the membrane respectively.

Effect of microwave irradiation on vacuum membrane distillation

Journal of Membrane Science, 2013
Abstract In this paper, a vacuum membrane distillation (VMD) system equipped with a microwave source was designed. And the polyvinylidene fluoride (PVDF) hollow fiber hydrophobic membranes were selected to carry out microwave vacuum membrane distillation (MWVMD).

Vacuum membrane distillation of seawater reverse osmosis brines

Water Research, 2010
Seawater desalination by Reverse Osmosis (RO) is an interesting solution for drinking water production. However, because of limitation by the osmotic pressure, a high recovery factor is not attainable. Consequently, large volumes of brines are discharged into the sea and the flow rate produced (permeate) is limited.

Heat and mass transfer in vacuum membrane distillation

International Journal of Heat and Mass Transfer, 2004
Abstract In the membrane distillation (MD) literature, the heat transfer coefficients of the boundary layers are usually estimated from well known heat transfer empirical correlations developed for non-porous and rigid heat exchangers. A difference between the mechanism of heat transfer in MD systems, which is coupled with transmembrane mass transfer,

Recovery of 2,3-Butanediol by Vacuum Membrane Distillation∗

Separation Science and Technology, 1994
Abstract A vacuum membrane distillation process using a microporous polytetrafluoroethylene (PTFE) membrane was developed to concentrate 2,3-butanediol from model 2,3-butanediol solutions and fermentation broths. A 0.22-μm PTFE membrane passed water vapor while retaining 2,3-butanediol. Water flux through the membrane was 4 kg/m2·h at 35°C and 12–14 kg/
