The objective of the present study is to evaluate the sustainability of solar still by enhancing the condensation rate using natural fibers on the glass cover. It is accomplished by employing naturally available Banana Fibers (BF) and Jute Fibers (JF) over the glass of the solar still (SS). The experimental investigation on Conventional Solar Still (CSS), Solar Still with Banana Fibers (SSBF) and Solar Still with Jute Fibers (SSJF) is conducted under similar meteorological conditions. The results reported that the glass cover temperatures of SSBF and SSJF are significantly reduced by 23% and 28% respectively relative to CSS. Also, the condensation rate in SSJF is comparatively better than SSBF and CSS. The significant factor for improving the condensation rate is the absorption, retention, and porosity of natural fibers. Nevertheless, the potable water yield of CSS, SSBF, and SSJF is noticed as 2.23, 2.87, and 3.18 L/m2, respectively. Besides, the viability of solar stills is assessed by economic analysis and the cost per liter (CPL) of water obtained from SSJF is about $ 0.029 with a payback period (PBP) of 4.7 months whereas SSBF and CSS are having a CPL of $ 0.034 and $ 0.041 with a PBP of 5.6 months and 6.8 months respectively.

“…Population growth and pollution of natural resources are among the reasons for scarcity of drinking water worldwide. The desert regions in Algeria, especially the city of El Oued, contain large quantities of saline groundwater, and a large solar field, and long insolation period throughout the year (Sharshir et al, 2020;Kabeel and Abdelgaied, 2017;Natarajan et al, 2022;Azari et al, 2021). Saltwater affects the human body and machinery and factories as well because it contains salt.…”

The present study aims to achieve the highest cumulative yield of the hemispherical distillers, by designing and constructing new reflector mirrors, which are truncated circular cone-shaped reflector mirrors (TCC-RM). To obtain the optimum inclination of TCC-RM that achieves a highest hemispherical distiller's performance, eight inclination angles ( 10o , 15 o , 20 o , 25 o , 30 o , 35 o , 40 o and 45 o with vertical) was experimentally studied. To achieve this, a series of experimental tests were carried out on the three hemispherical solar distillers, the first represents the reference distiller (traditional hemispherical solar distiller-THSD) and the other two devices are the hemispherical solar distiller with truncated circular cone-shaped reflector mirrors (HSD-TCCRM) with different inclination angles. The experimental results indicate that utilizing TCC-RM with a 25 o inclination angle achieves the maximum cumulative yield of 8.35 L/m 2 with an improvement of 42.74% compared to THSD. While the utilization of TCC-RM with the inclination angles by 30 o , 35 o , 20 o , 40 o , and 15 o achieves the cumulative yield of 7.
