“…It was found that there was an enhancement of productivity by about 40% compared to conventional systems. Also, Natarajan et al (2022aNatarajan et al ( , 2022b and Suraparaju and Natarajan (2022a) experimentally analysed the effect of low-cost and naturally available materials on the evaporation and condensation rates of solar still. It was observed that the tilization of porous materials in the absorber enhanced the evaporation rate and the hydrophilic fibres over the glass cover enhanced the condensation rates significantly.…”

“…Also, the ever-increasing demand for drinking water is driving research on desalination plants around the world. Since water is essential for all living beings, the production of drinking water should be cheaper and environmentally friendly (Suraparaju and Natarajan, 2022a). However, the usage of renewable energy sources for driving desalination units is one of the better ways to address environmental issues as well as attain sustainable development goals given by the United Nations.…”

Purpose The utilisation of renewable energy sources for generating electricity and potable water is one of the most sustainable approaches in the current scenario. Therefore, the current research aims to design and develop a novel co-generation system to address the electricity and potable water needs of rural areas. Design/methodology/approach The cogeneration system mainly consists of a solar parabolic dish concentrator (SPDC) system with a concentrated photo-voltaic module at the receiver for electricity generation. It is further integrated with a low-temperature thermal desalination (LTTD) system for generating potable water. Also, a novel corn cob filtration system is introduced for the pre-treatment to reduce the salt content in seawater before circulating it into the receiver of the SPDC system. The designed novel co-generation system has been numerically and experimentally tested to analyse the performance at Karaikal, U.T. of Puducherry, India. Findings Because of the pre-treatment with a corn cob, the scale formation in the pipes of the SPDC system is significantly reduced, which enhances the efficiency of the system. It is observed that the conductivity, pH and TDS of seawater are reduced significantly after the pre-treatment by the corncob filtration system. Also, the integrated system is capable of generating 6–8 litres of potable water per day. Originality/value The integration of the corncob filtration system reduced the scaling formation compared to the general circulation of water in the hoses. Also, the integrated SPDC and LTTD systems are comparatively economical to generate higher yields of clean water than solar stills.

Suraparaju and Natarajan 29 improved the condensation rate of solar still using the natural fibers on the glass cover. They found that using the Jute Fibers improved the yield from 2.23 to 3.18 L/m 2 .…”

The present study aims to improve the palatable water production from the hemispherical cover solar distiller (HSD). To augment the palatable water produced from the hemispherical cover, a black sponge was utilized as a porous medium using different thicknesses, which augments the interfacial evaporation through the capillary effect of the water through the sponge. The rate of condensation of the hemispherical cover depends on the higher interaction of air from the ambient through wind velocity as the exposure area of the hemispherical cover is relatively higher as compared to the other traditional distillers. The rate of evaporation from the distillers depends on the interfacial materials used in the distillation unit, and this is achieved by using a highly porous black sponge to attain a higher evaporation rate. The thickness of the black porous sponge was optimized (1 to 4 cm), which was the operating parameter for better interfacial evaporation through the sponge, and the same has been compared to the conventional HSD without a porous sponge medium. Results showed a significant improvement in the evaporation rate using a porous medium as the palatable water produced from the HSD was improved by 72.29% using 3 cm as sponge thickness inside compared to the conventional HSD without the porous medium. The cumulative palatable water produced from the HSD using 3 cm as sponge thickness was found as 7150 mL/m2, whereas the conventional HSD without sponge, it was found as 4150 mL/m2. Moreover, using a porous sponge layer as an interfacial evaporation medium, the exergy and energy efficiencies were improved by about 512.87 and 70.53%, respectively. Similarly, with the influence of a porous sponge as an interfacial evaporation medium, the distilled water cost decreased by 41.67% more than the conventional HSD.

Access to safe drinking water remains a global challenge, primarily due to the prevalence of water contamination in various regions. Numerous methods have been explored to address this issue and convert polluted water into potable sources. However, the cost associated with these methods often hinders their widespread adoption. Solar distillation, harnessed by abundant solar energy, emerges as a promising and sustainable solution. Although solar distillation technology has made significant advancements in recent years, the endeavor to boost its efficiency remains a substantial challenge. Typically, solar stills yield between 4 and 6 liters of fresh water per square meter of solar still per day under ideal circumstances. Notably, both single‐basin and double‐basin solar stills have been extensively researched to discover methods for enhancing their productivity. A notable innovation in this field, the tubular solar still (TSS), has gained recognition for its capacity to improve productivity. The present review article systematically examines the development of efficient and cost‐effective solar distillation systems on a global scale. It provides a comprehensive analysis of the literature pertaining to techniques employed to enhance TSS performance. The study categorizes these techniques, conducts in‐depth evaluations of both experimental and simulation studies, and offers a meticulous comparison of various strategies to optimize TSS functionality. Furthermore, the article identifies existing research gaps and puts forth prospective directions for advancing TSS efficiency.
