A Novel Air Backwashing Method for Reversing Wetting in Membrane Distillation
This paper describes a new method to reverse wetting of the hydrophobic membrane in membrane distillation. Pressurized air is pushed through the wetted membrane from the distillate side, thus forcing out wetted feed water, instead of merely allowing it to evaporate. To test its effectiveness, the liquid entry pressure (LEP) of the membranes was tes...
