Theoretical and experimental studies on desalination using membrane distillation

Pure water direct contact membrane distillation experiments were carried out. A model based on a dusty-gas model of gas transport through porous media showed good agreement with the experimental results over the entire range of feed temperatures and recirculation rates studied. The model was also used to predict performance of salt solutions desalination. Fluxes similar to those typically obtained with reverse osmosis were predicted.
