An Experimental Analysis of Solar Still Using Different Thermal Energy Storage Materials

Abstract

Water desalination can be done using solar water, which is the most significant strategy for acquiring pure water. The problem of pure water is an important challenge facing our society. The availability of pure water is minimal, which does not fulfil the needs of a growing population. The productivity of conventional solar stills needs to be higher, which needs to produce more distilled water. The primary objective of this research is to increase the productivity of SSs with thermal ESM inside the basin. The experiment is conducted at the Sushila Devi Bansal College campus in Indore at a tilt angle 23º. In this experiment, a comparative analysis was done between conventional and solar solar still using thermal energy storage material. The silica sand particle and the black-painted aggregate stones have been used inside the water basin as a thermal ESM to enhance the productivity of the solar still. It was found that the distilled output of the solar still with black-painted aggregate stones gave a superior result compared to the silica sand-based and conventional solar still. The solar still with black painted aggregate stones and the silica sand-based solar still have extra productivity of 131.25% and 87.05%, respectively, compared to the standard solar. It was noticed that the distilled output of solar still using black painted aggregate stones, silica sand particles, and conventional mode is 2590 ML, 2095 ML, and 1120 ML with a basin area of 0.5 m² in 12 hours.
