“…The modified basin-type double-slope multi–wick solar still was proposed by Pal et al. [18]. A number of experiments was performed on the modified double-slope solar still; the daily productivity values obtained were 4.50 and 3.52 L/m 2 for black cotton wicks and jute wicks, respectively, at a 2-cm basin water depth.…”

A solar still is used to convert saline water into potable water by means of the distillation process. In order to improve the productivity of conventional solar still, various modifications are implemented by researchers. In the present study, multiple V-shaped floating wicks are used to enhance heat absorption and thereby increase productivity. The experiments are performed during the summer and winter seasons in Rewa, India (Latitude: 24.5373° N; Longitude: 81.3042° E). These multiple floating wicks are made from black jute cloth wrapped in V-shaped pieces of thermocol. Because of their V-shaped profile, the evaporative surface area of modified solar still is 26% larger than that of conventional solar still. The maximum daily productivity in one of the clear days is found to be approximately 6.20 kg/m 2 in summer and 3.23 kg/m 2 in winter with daily efficiencies of 56.62% and 47.75%, respectively. A theoretical thermal model is formulated by using the energy balance equations of the modified solar still. Reasonable agreement was seen between the theoretical and experimental results of modified solar still. An economic analysis is also performed for the modified solar still and conventional solar still; in a 10-year life cycle, the annual cost of distilled water is estimated at Rs. 1.81/kg for the former and Rs. 2.24/kg for the latter.

Potable water is one of the vital necessities for the society. The assurance of availability of clean water to society is a big confront due to restricted accessibility of clean water on planet Earth. Solar desalting systems can be used for justifying the appropriate supply of fresh water in distant localities by the use of ample sunlight. In spite of conventional solar desalting systems, various other designs of solar desalting systems are used to boost the overall performance of the system. In this work, various new conceptual designs of passive solar desalting systems have been reviewed to understand better, efficient and productive performing system along with various novel solar desalting systems that can inculcate the real feeling of performing information among the researchers. An overview has also been established for better utility indications and comparative performances among all solar desalting systems. The interpretations have been accomplished with the better results and some favor has also been recommended for the future betterment and building novel designs to meet the feasible hurdles.

“…In this view, solar stills have attracted the interest of many in the field of solar thermal desalination. Improvement in designs of conventional single/double sloped solar stills have been suggested using stepped solar stills , single and double effect , wick materials , new conceptual designs of passive solar stills have been proposed as well as methods to improvise the performance of solar stills through better design of components and combination with other devices (known as active solar stills) a reflector , solar collector , and concentrator PV/T desalination and so on have been proposed in recent years. These approaches lead either led to optimization of design or an increase in input energy to the system thereby increasing the performance of the solar still.…”

A novel experimental approach is presented where studies have been conducted on a solar still at four specific heights in the range of 0.266–0.341 m (in steps of 0.025 m) keeping other dimensions constant. Performance of solar still is established under indoor environment to suppress meteorological factors. Uniform heat was supplied to the solar still through flat plate‐type electrical heaters. For each specific height, the performance of the solar still was evaluated at five heat fluxes (600–1000 W/m2 in steps of 100 W). Performance of solar still at different specific heights was compared in terms of operating temperatures, productivity, and efficiency. It was found that reduction in specific height enhances distillate productivity as well as thermal efficiency of the solar still due to reduction in cavity volume and an increase in average operating temperature. An increase of in daily distillate yield of 89.44% (at 600 W/m2), 56.07% (at 700 W/m2), 28.50% (at 800 W/m2), 38.60% (at 900 W/m2), and 37.38% (at 1000 W/m2) between Case 1 to Case 4 was observed. Further, between Case 1 and Case 4, the thermal efficiency increased from 27.29 to 46.18%, 32.73 to 51.06%, 36.82 to 52.17%, 41.25 to 56.79%, and 42.55 to 57.50% at 600, 700, 800, 900, and 1000 W, respectively. Results demonstrate that for a particular specific height the total daily productivity increases linearly with heat flux. Correlation for estimating thermal efficiency of solar still is proposed in terms of the aspect ratio and input power. © 2019 American Institute of Chemical Engineers Environ Prog, 38: e13227, 2019
