Solar pond and membrane distillation merger in Nevada University

Membrane distillation (MD) is a thermally driven membrane separation process that involves evaporation of volatile constituents (water in desalination applications) through a hydrophobic, microporous membrane. The vacuum-enhanced MD process recently patented by researchers at the University of Nevada, Reno in the United States has now been coupled with some equally interesting research at the university on solar ponds. The configuration is now being studied using a small-scale indoor pond and new capillary MD membranes. While MD has been studied in the past in conjunction with solar ponds, new membranes, new techniques and new auxiliary technologies are improving MD, solar ponds and their synergistic combination. This article was first published in the February/March 2010 issue of Desalination & Water Reuse magazine.
