Influence of water mass on the performance of spherical basin solar still integrated with parabolic reflector

Abstract

Continuous availability of fresh drinking water to meet the growing social, economic and environmental need of society is one of the major concern for present situation. Solar desalination is sustainable device to get the potable water from brackish water. However, the lower productivity of solar desalination is the major obstacle for worldwide applicability. In the present paper, an ingenious amendment in form of spherical basin solar still has been integrated with parabolic reflector. The spherical basin solar still has been developed and performance has been investigated for various water mass such as 1 L, 2 L, 3 L, 4 L and 5 L in basin. The daily yield of 3.5409 L/m2, 4.7860 L/m2, 6.7174 L/m2, 7.4744 L/m2 and 8.2596 L/m2 was obtained for 1 L, 2 L, 3 L, 4 L and 5 L water mass in basin respectively. The daily average efficiency of spherical basin solar still was obtained 19.56%, 23.92%, 30.83%, 34.49%, 39.06% for the 1 L, 2 L, 3 L, 4 L, 5 L water mass in basin respectively. From experimental results, it has found that the distilled output increases with increase in mass of water in basin.
