Utilization of a forced condensing technique in a moving film inclined solar desalination still

Abstract To overcome drawbacks of coventional inclined solar desalination stills, a new condensing technique was developed at the University of Bahrain. The water vapor is extracted as soon as it is formed before it reaches the glass cover and is allowed to condense in a separate unit kept at a much lower temperature. In a study to find optimum performance of the system, the thermal and overall efficiency were found to be about 70% and 60%, respectively. The system was compared for efficiency with similar conventional types which use a natural condensation method on an inner glass surface. A cost benefit analysis has been made on the economic viability of the system.
