Solar stills integrated with a mini solar pond - analytical simulation and experimental validation

Comparison between theoretical and experimental analysis of a mini solar pond assisted solar still is presented in this paper. In a mini solar pond, experiments were conducted for different salinity. It was found that the optimum value of salinity in the mini solar pond is 80 g/kg of water. Effect of sponge cubes in the still, effect of integrating mini solar pond with the still and combination of both are discussed. The average daily production of solar still is found to be increased considerably, when it is integrated with a mini solar pond. Theoretical analyses were made using conservation of energy and the results obtained give very good agreement with the experiments.
