Three membrane distillation processes, direct contact membrane distillation, sweeping gas membrane distillation and vacuum membrane distillation, have been experimentally studied in a shell-and-tube capillary membrane module. Distilled water and sodium chloride aqueous solutions were used as feed. Different flow rates and temperatures were employed. Theoretical models that consider the heat and mass transfer through microporous hydrophobic membranes have been developed. A comparative study was made between the three configurations.
