Membrane Distillation

Membrane Distillation
Introduction

Membrane distillation(MD) is an thermally driven membrane process in which a hydrophobic microporous membrane separates a heated feed solution and a cooled receiving phase.The temperature difference across the membrane generates a water vapor pressure gradient and causes water vapor transferring through the pores from high vapor pressure side to the low one.
