“…The comparison between the glass solar still, developed in the present study, and some other solar stills previously developed by other authors [17], [18], [32], [33] and [34] is shownin ( Table 3). The results presented in the table below suggest that our findings are in good agreement with those of other investigations.…”

The present work aims at improving the performance of a glass solar still using different new absorbers (enameled sheet metal, blackened sponge, blackened gravel, clay, charcoal and quicklime) as sensible heat storage systems under the desert climatic conditions of Adrar. Most of the solar stills studied up to now are made of sheet metal with a black coating. The main disadvantage of these systems lies in their high corrosion and water contamination by the rust of the metal used and some toxic elements. Two solar stills were designed, constructed and tested in this study in order to compare the efficiencies of the different solar desalination systems. The first one is a glass solar still with sensible heat storage materials and the second one is a conventional solar still. The solar still studied was fabricated from cheap locally available glass and healthy materials. The hourly water and glass temperatures, productivity, and efficiency of the still were measured and evaluated experimentally. Moreover, a comparison between the different materials used as absorbers was carried out as well. From the results, it was observed that the system could produce 5.6 l/m²/day of fresh water; it was also found that metal was the best absorber as it exhibited the highest productivity as compared with the other absorbers. However, the maximum volume produced by the conventional solar still was only 4.88 l/m² per day. The lowest productivity, of about 1.6 l / m² /day, was observed with quicklime. In addition, physical analysis of distillate output shows that the quality of water produced is better.

“…Cationic resin with peat, zeolite, activated carbon, and anionic resin was more effective than a single form of adsorbent [363]. Ouar et al [378] reported an experimental yield analysis of groundwater solar desalination using absorbent materials. Black absorbents, such as bitumen, charcoal and Chinese ink were separately added within the absorber plate of conventional solar still.…”

Functional materials in desalination: A review

2019

View full text Add to dashboard Cite

This paper reviews various functional materials used in desalination. Desalination of the abundant seawater resource has emerged as a promising technology to meet the current fresh water demands. For improved performance, often functional materials such as photocatalysts, electrocatalysts, photothermal materials, sorbents, antibacterial materials and magnetic materials are utilized in thermal, membranebased and other desalination technologies. With an aim to provide an insight on the existing research on functional materials and the purpose behind using such in desalination, this review collates different research studies of various functional properties and the subsequent materials utilized for those properties. New generation materials such as carbon nanotubes (CNTs) and graphene form a major part, where they exhibit multiple functionalities with improved water transport properties, and thus have been deemed as very attractive enhancers to the desalination technology. Nevertheless, most of the functional materials, such as nano-TiO2, nano-zeolites, graphene, CNTs and magnetic nanoparticles suffer from several limitations such as specialized synthesis techniques, agglomeration, leaching and environmental and health concerns. This review focuses on such challenges and suggests improvements for enhanced incorporation of these in the desalination technology. Lastly, emerging new technologies, advanced fabrication methods and novel functional hybrid materials are reviewed to equip the readers with the latest research trends. Thus, a comprehensive review is essential which will provide current and future researchers an insight on the importance and significance of utilizing functional materials in various desalination technologies.

Energetic and exergetic investigation of single slope solar still with sponge and circular hollow fins at different water depths

In this investigation, the experimental analysis of single slope solar still (SSSS) using hollow pin fins and sponge is done. The analysis of a SSSS using various sizes of water depth located in the basin was investigated based on energy and exergy analysis. The performance was estimated for the different water depths such as 15, 30, and 45 mm in basin. Four types are considered, type 1: traditional solar still (TSS), type 2: TSS with sponge, type 3: TSS with circular hollow fins and type 4: TSS with sponge and circular hollow fins. The effects of the sponge, water depth and the use of hollow pin fins were also examined.The performance was estimated for the variation of water depth such as 15, 30, and 45 mm in basin. The energy efficiency of Type 4 (TSS with sponge and circular hollow fins) is 20% higher than that of Type 3 (TSS with circular hollow fins), 38.47% higher than that of Type 2 (TSS with sponge) and 79.98% higher than that of Type 1 (TSS).
