Water Desalination using Vacuum Membrane Distillation Essay

irrigate Desalination using Vacuum tissue layer Distillation - Essay ExampleOf course, it can also be used for water desalination 5.Vapor migrates from the membrane surface to the permeate ramp. How this process occurs varies with the different configurations, depending on the feed solution which is treated 3, 11, 16. All the configurations have advantages and disadvantages, depending on their applications. In Direct Contact Membrane Distillation, for instance, the membrane is in direct contact with the water only during liquid phases.According to classical warmth transfer theory, a thermal boundary is formed when liquid is in direct contact with a solid surface when their temperatures differ. This thermal boundary stays next to the solid surface, where the liquid exhibits its temperature fluctuations. The process of love and messiness transfer illustrates the membrane distillation process, wherein a microporous membrane separates two fluids of differing temperatures (membrane thickness of). The feed temperature decreases from at its bulk to at the membranes surface. Accordingly, the permeate temperature increases from at its bulk to at the membranes surface. Two thermal boundary layers appear at the feed side (with the thickness of) and the permeate side (with the thickness of) of the membrane respectively, as shown in Fig. 3.where is the mass transfer flux through the membrane and is the possible heat of the volatile component. Here, is only a small part of the energy transferred through the membrane in the form of latent heat. The temperature difference between the two sides of the membrane also conducts heat through the membrane and the gas that fills the pores with flux, written asThe equation illustrates the temperature difference between the two sides of the hydrophobic membrane. Accounting for the drying up pressure difference is illustrated by, which is the driving force for mass transfer through the membrane. Three mechanisms regulate the mass transfer through the membraneThe mass transfer mechanism
