Concentration of must through vacuum membrane distillation

Desalination, 2002
Vacuum Membrane Distillation is studied for the concentration of fruit juices up to 50°Brix. The fluxes of water and of the relevant aroma compounds are experimentally examined for a typical must, as a function of temperature, sugar content and downstream pressure. The process leads to juice concentrates still retaining interesting amounts of the aroma

Phenomenological Comparison of Vacuum Membrane Distillation for VOC Removal and Desalination

Processes
Vacuum Membrane Distillation (VMD) is a separation process applied to liquid solutions; however, there are phenomenological and operational differences depending on whether the component to be separated is the solute or the solvent. The objective of this

Desalination by vacuum membrane distillation: sensitivity analysis

Separation and Purification Technology, 2003
Abstract 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, 2020
Membrane 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 ...

Vacuum membrane distillation for the treatment of coffee products

Separation and Purification Technology, 2019
Vacuum Membrane Distillation (VMD) was applied in two production lines of the coffee industry: the concentration of the coffee extract and the dehydration and recovery of caffeine. Experiments were carried out by using a commercial flat microporous membrane made of polypropylene (0.2 ?m pore size).

Vacuum Membrane Distillation (VMD)

2014
Vacuum 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).
