Experimental investigation of single slope solar still with <i>Eucheuma</i> (<scp>agar‐agar</scp>) fiber for augmentation of freshwater yield: <scp>Thermo‐economic</scp> analysis

Purified drinking water is the basic need of human beings. Purification of water assisted by freely available solar energy can be the best alternative compared with other water purification techniques available in the market today which consume nonrenewable energy. Distillation, which is the most ancient method, is being used for water purification. The device in which solar thermal energy converts brackish water into pure drinkable form is known as a solar still. Present article reports an extensive study of numerous designs of solar stills. The article also includes a review of effect of each parameter that influences the water productivity that is, pure water.Considerations of thermodynamics, heat transfer, and mass transfer are also explained in brief. The reviews of various kinds of analysis namely, theoretical, experimental, computational, cost, and water quality have been reported.

et al. 2022

In the present manuscript, performance studies of Solar Still (SS) were studied for the climatic conditions of Erode, India. Three different experiments were conducted:Conventional SS (CSS), CSS incorporated with blue metal stones, and CSS incorporated with tar-coated blue metal stones. Furthermore, the energy and exergy efficiency of the CSS is evaluated. The daily-distilled yield by incorporating the tarcoated blue metal stones in CSS is 3.21 Kg and blue metal stones in CSS is 2.89 Kg with augmentation of 34.4% and 27%, respectively than the CSS. The distilled water production during daytime (8 a.m.-6 p.m.) from the CSS, CSS incorporated with blue metal stones, and CSS incorporated with tar-coated blue metal stones is 2.02, 2.59, and 2.83 kg, respectively. Similarly distilled water production during nighttime (7 p.m. to 11 p.m.) is 0.08, 0.29, and 0.39 kg, respectively. The distilled water production during daytime and nighttime from the CSS incorporated with tar-coated blue metal stones and CSS incorporated with blue metal stones are 28.3%, 22%, 78.6%, and 71.7% higher than the day-time and night-time yield from the CSS. Also, the energy and exergy efficiency of the CSS incorporated with tar-coated blue metal stones and CSS incorporated with blue metal stones is 21.6% and 1.63%, and 20% and 1.4%, respectively.
