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.

“…Even though some Nanosheet assembled [23] and paper based composite membranes [24] are being investigated but the use of these latest techniques require exceptional arrangements. Different wick materials like jute 30% [25], sponge cubes 18% [26], cotton cloth [27,29] coral fleece fabric and weir mesh [28] black velvet fabric [29] are also used for improving the evaporation rate but the thermal efficiency remained limited (20-40%).…”

Water is a prerequisite for the existence of life on earth. Rapid growth in the global population and industrialization have created a dearth of freshwater resources. Escalating water scarcity suggests that the use of passive solar stills is the most suitable and viable option in the arid and semi-arid areas around the world. In this study, the yield of wick type floating solar still is experimentally investigated for different wick materials. Capillary rise and absorbency of two different absorbers are considered as performance parameters for analysis of the research. Based on results, crepe paper with absorbency (1.8s) and capillary rise (112mm/h) proved a better absorber for higher productivity of the still. The efficiency of still with crepe paper was observed to be 16.68% higher than that of glass fiber sheet when applied in still during the investigation. The maximum internal temperature and the productivity of still were 9.1°C and 0.8 L/day respectively higher when crepe paper was used instead of a glass fiber sheet as a wicking material.
