  • Membrane distillation

    Membrane distillation is a thermal process in which only vapour molecules can pass through a hydrophobic membrane. The driving force for the separation is the vapour pressure and not the total pressure, as with reverse osmosis.Increasing the temperature of the feed increases the vapour pressure and therefore the vapour pressure gradient, which is the driving force.
