Superhydrophobic modification of ceramic membranes for vacuum membrane distillation
Chinese Journal of Chemical Engineering, 2017Abstract The hydrophobically modified ceramic membranes have great potential for energy-efficient membrane distillation. In this work, flat-sheet ceramic membranes with a superhydrophobic surface were fabricated by grafting 1 H ,1 H ,2 H ,2 H -perfluorooctyltrichlorosilane or 1 H ,1 H ,2 H ,2 H -perfluorodecyltriethoxysilane and followed by ...

Vacuum membrane distillation of seawater reverse osmosis brines
Water Research, 2010Seawater 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.

Modeling of pore wetting in vacuum membrane distillation
Journal of Membrane Science, 2019Abstract In this work simulation results for the pore wetting of vacuum membrane distillation (VMD) are reported, considering heat and mass balance at liquid/vapor interface when steady state is achieved. Two cases were studied. In case 1, the system is in isothermal condition.

Desalination by vacuum membrane distillation: sensitivity analysis
Separation and Purification Technology, 2003Abstract In order to enhance the performance of the vacuum membrane distillation process in desalination, i.e. to get more flux, it is necessary to study the effect of operating parameters on the yield of distillate water. Simple techniques including the normalized dimensionless sensitivity factor and temperature polarization coefficient as well as ...

Supply of solar energy in vacuum membrane distillation
International Journal of Ambient Energy, 2020Membrane distillation (MD) is a novel process introduced to overcome the disadvantages of the conventional distillation process. MD has gained much interest, principally, for its lower energy demand and higher rejection factors. This thermal process has the advantage of being able to be associated with solar energy to produce drinking water at low ...

Numerical modeling of the vacuum membrane distillation process
Desalination, 2013Abstract In this study, one-dimensional vacuum membrane distillation (VMD) model is suggested for predicting the performance of seawater desalination to evaluate the performance of hollow fiber type VMD module. The energy and momentum balance equations, as well as the heat and mass transfer equations, are simultaneously solved to determine the ...

Vacuum Membrane Distillation (VMD)
2014Vacuum membrane distillation (VMD) is one of the possible configurations of membrane distillation, where vacuum is applied at the distillate side in order to create the driving force for the water vapor and volatile transfer from the feed to the permeate side (Fig. 1).

A ballistic transport model for vacuum membrane distillation
Journal of Membrane Science, 2014Vacuum Membrane Distillation (VMD) as other membrane distillation (MD) techniques is receiving much attention for its ability to produce drinkable water at low cost. Aiming to analyze the VMD process and particularly mass transfer through porous membranes, a ballistic flow model is developed to predict fluxes out from high aspect ratio cylindrical ...
