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.

Solar desalination is a process to convert saline water into potable water by the application of solar energy. The enhancement of the distillate output of the solar desalination is low, so it is not considered as a method to produce potable water. A heat exchanger is an important device used for heat transfer applications. The present review article illustrates the application of a heat exchanger with a solar desalination system to enhance the distillate output. In the current review, it is found that the heat exchanger is an important device to improve the distillate productivity of the solar desalination system. Finally, the future work and future challenges of using a heat exchanger with a solar desalination system are presented.

“…As a consequence, different designs and modi cations can be found in the literature of solar stills, and all these modi cations aimed to enhance the solar still performance. The modi cations are like stepped (Essa et al 2020b), disc (Essa et distiller with nano uids (Shanmugan et al 2020), distiller with heat exchanger (Yadav 1991), inverted still (Suneja &Tiwari 1999), and pyramid distillers (Modi &Nayi 2020, Nayi &Modi 2018). Moreover, the distillers were examined when utilizing nanomaterials (Kabeel et Attia et al (Attia et al 2021c) studied experimentally the effect of using metal trays (copper, zinc and iron) xed on the bottom of a hemispherical solar distillation device to improve its productivity.…”

Numerous studies are being conducted on solar desalination systems with creating new designs to improve the efficiency and yield of these systems. Hemispherical solar still has a relatively large throughput because of its large exposure and evaporation surface areas compared to the other distiller designs. To get the optimal conditions of the parameters that provide the highest productivity of the hemispherical still, three hemispherical basin stills were fabricated and tested. The experiments were performed in three stages: In the first one, the traditional hemispherical solar still THSS (a reference distiller) was compared by THSS with internal reflective mirrors (THSS-IRM). In the second stage, the effect of using different basin metals (THSS with basin metal of zinc (THSS-IRMZ) and basin metal of copper (THSS-IRMC)) with internal reflective mirrors was studied. In the third stage, the two distillers were investigated under using energy storage medium (30 g/L sand grains for each). The THSS with internal reflective mirrors, basin metal of zinc, and energy storage medium is abbreviated by THSS-IRMZSG. Also, THSS with internal reflective mirrors, basin metal of copper, and energy storage medium is abbreviated by THSS-IRMCSG. Moreover, THSS with internal reflective mirrors and energy storage medium is abbreviated by THSS-IRMSG. The results showed that the combination of using internal reflective mirrors, basin material (copper) and energy storage medium provided the best improvement of hemispherical distillation device. The maximum cumulative yield of THSS-IRMCSG was 11.9 L/m².day, while the reference distillation device gave a total yield of 4.65 L/m².day. So, the productivity was improved by around 156%.
