Vacuum Membrane Distillation

Efficient and cost-effective approach to membrane distillation

Technology Overview

Membrane distillation, utilized in a number of commercial applications, is the thermal driven transport of vapor through non-wetted porous hydrophobic membranes. The developed vacuum membrane distillation system uses an aspirator to generate a vacuum pressure for drawing permeate from a membrane module. The aspirator generates the vacuum pressure by receiving and passing a circulating liquid and combines the permeate with the circulating liquid such that the permeate condensates in the circulating liquid.
