“…The different configurations of SS basin, including plain, corrugated "V" type, and compartmental type, were fabricated and tested (Gnanaraj and Velmurugan 2020). Furthermore, pebbles, white marbles, color marbles, blue marbles, kadappa gravel, black granite gravel, color cotton cloth, black cotton, jute cloth, black jute, and black sponge were used as energy materials to improve the heat storage in the basin.…”

The sun is the primary source of life on the earth. The heating effect of the sun provides a more fruitful environment for mankind. In addition, solar energy in the form of thermal radiation has been utilized for solar thermal applications and space heating. With abundant solar radiation, the emergence of the solar desalination has been emerged as a viable solution for water purification by utilizing solar stills. However, solar-powered distillation is relatively a slow process due to the requirement of bulk heating. To suppress thermal conduction to bulk water, various photothermal materials were employed. However, there are many governing parameters which influence the productivity, including solar intensity, cloud, wind, ambient air temperature, humidity, solar absorption of blackened surface, depth of bulk water, feed water type, angle of condensation surface, water film thickness, underneath the condensing surface, and experiment period. Further, systematic and continuous experiments for extended periods are essential for determining the stability and durability of a solar desalination system. The main objective of this article is to review all the experimental studies conducted for two months at minimum up to 1-year duration. In addition, all the SDSs handled in this study further were examined by solar geometrical factors, including day length (DL) and position of the sun or zenith angle (θ z ). As a result, the sunshine hours, day length, and the solar zenith angle play an important role in the water evaporation rate. Lower solar zenith angle and longer day length (more sunshine hours) are desirable for higher water productivity.

“…Security of water is one of the difficult challenges that many countries face to maintain their life and development plans, especially those that suffer from water scarcity. Accordingly, the strict policy of managing water resources and the communities' awareness of the importance of this problem is the basis of the plan to control the water resources of any country [1,2]. Most of the countries in the Middle East, especially the Gulf Cooperation Council (GCC), need exceptional measures to allocate their water resources rationally to ensure running their life and development plans properly.…”

Providing water for different uses to maintain life activities is a target for many nations. So, managing the existing water resources and finding new water sources are essential for any nation's water security. In the present article, 4 years daily meteorological data, such as relative humidity, air-temperatures, and global solar irradiation were analyzed to support the explanation of high-level humidity in the coastal plains of Oman, and the effect of that on water production from atmospheric moisture. What applies to the coast of Oman is also valid on the coasts of the Gulf Cooperation Council. It is found that the annual mean value of the RH% along the Omani coast is about 68% for 4 years (2016–2019). Also, the study of the air-temperatures data revealed very clear decreasing in the direction toward the south of Oman due to the geographical diversity. It is found that the lowest annual air- temperatures were in the far south city, Dhalkut (about Max., Mean, Min., 25, 22, 20 °C, respectively). Three years (2017–2019) of global solar irradiation data of Muscat International Airport showed a maximum value of around 7300 W/m2 in June. In addition, a part of the research work was to investigate the byproduct drain-water that comes out from big air-cooling units with a rate power of about 21.73 kW each. The result indicated that a Net Annual Rate of freshwater of about 1892 m3/year can be accumulated from one supermarket air-cooling units nearby the line coast of Oman. Also, the chemical, physical, and bacterial tests were carried out to find some parameters, such as TDS, EC, pH, and bacterial contamination. The results were encouraging towards the purity of the byproduct water, and the existing bacteria could be killed by solar energy.
