Pervaporation membranes are designed to separate liquid mixtures that are difficult to process by conventional methods. During the process, the feed remains in the liquid phase, while the target component selectively passes through the membrane and is removed as vapor.
 

This technology is especially suitable for:

·Solvent dehydration
·Azeotropic mixture separation
·Separation of close-boiling liquids
·VOC and trace organic recovery from water
·Heat-sensitive liquid separation

Unlike conventional filtration membranes that rely on pore size, pervaporation membranes work through a solution-diffusion mechanism, allowing specific components to pass through the membrane more easily than others.
 

Key Advantages

·High separation selectivity
·Energy-saving compared with traditional distillation in many applications
·Suitable for complex liquid mixtures
·Gentle treatment of heat-sensitive materials
·Easy to combine with other separation processes
