Augmenting the productivity of solar still using jute cloth knitted with sand heat energy storage

The best methods in improving the fresh water yield from the solar still is incorporating sensible heat energy storage materials. This paper presents the improvement in fresh water and thermal from the conventional basin solar still using sensible heat energy storage knitted with jute cloth wrapped over the entire surface of the material under different water mass. Experimental investigations were carried out in the single slope solar still with and without jute cloth knitted with the material and for validation of results the solar still without any material is tested for the same experimental condition. Results show that the yield of fresh water is completely depends on the parameters such as mass of sensible energy material and depth of water kept in the basin. The yield of fresh water under least water mass (mw = 20 kg) from the solar still with and without jute cloth knitted with sensible heat storage material were found as 5.9 and 5 kg/m², respectively.
