Membrane distillation (MD) has recently gained popularity among the scientific and engineering community. Membrane distillation can be used for water desalination, treatment of industrial effluent, purification of pharmaceuticals, processing of foods, and the removal of organic compounds from aqueous streams. The membrane distillation process is driven by a temperature gradient created across a microporous membrane that separates vapor-liquid / liquid-liquid phases in equilibrium. The process has many advantages compared to conventional distillation or pressure-driven membrane processes including: the possibility to achieve complete rejection of non-volatile components, lower operating temperatures and pressures, and the use of membranes with relatively poor mechanical properties.
This Virtual Special Issue of the Journal of Membrane Science highlights some of the most important contributions to the field of Membrane Distillation, including a specially written Introduction that summarizes the development of this technology and the current state-of-the-art.
