“…Water harvesting from air is done with several types of desiccants, either solid (e.g., SiO2) or liquid (CaCl2), and experiments have been carried out to see if increasing the desiccant amount leads to an increase in the quantity of produced fresh water or not. It has been discovered that increasing SiO2 amounts improves not just the moisture absorption from the atmosphere during the night, but also the absorption of solar energy and the evaporation operation throughout the day (Essa et al, 2020). At the same regeneration situation, the substance temperature rises as the percentage of Calcium chloride increases.…”

“…Researchers used a variety of modifications to improve water production from the atmosphere, such as using a parabolic concentrator to concentrate solar radiation in a fixed point (Elashmawy & Alshammari, 2020), (Srivastava & Yadav, 2018), increasing the number of shelves (Kabeel, 2007), (William et al, 2015) or installing fins (Essa et al, 2020) inside the apparatus to increase the surface area of the apparatus as well as the amount of desiccant used within the device, and Gravels are used to raise the desiccant's operating temperature because they have a high solar absorptivity and specific heat, making them an excellent absorber of solar energy and thermal energy storage (William et al, 2015).…”

“…The results showed that using the longitudinal fins and longitudinal fins with gravels boosts the productivity by nearly 72% and 166% respectively, and the system efficiency by nearly 15% and 35 % respectively. The highest water productivity found to be 400 mL /m 2 (Essa et al, 2020). is used for the desorption process.…”

Drinking water and utility water are indispensable elements in meeting many vital needs, especially drinking, cooking and cleaning. Unconscious agricultural irrigation, pollution, and population growth cause water scarcity that humanity must cope with. As a result of global warming and climate change, especially the amount of potable water is decreasing, making it difficult to access clean water resources. The occupancy of drinking water sources decreases in high temperature seasons and some of them even disappear. This situation has made it necessary to search for alternative methods to obtain drinking water. One of these methods is to obtain potable water from atmospheric air containing high amounts of water. With the widespread use of this method, the scarcity of drinking water can be alleviated to a certain extent. In this study, the processes of condensing the water in the atmospheric air by using solar energy, which is a renewable energy source, and thus obtaining potable water are discussed. Efforts to increase the efficiency of obtaining potable water by using various absorbents and by various systemic solar still designs have yielded positive results. As a result of this literature review, the limits of the studies and their regional effectiveness were evaluated together. The effect of temperature, velocity, humidity of the atmospheric air and the amount of solar radiation on the process were evaluated. It has been concluded that certain desiccant materials with good water absorbers such as calcium chloride and silica gel can be used effectively in the processes of obtaining potable water from atmospheric air by developing correct designs. It has been demonstrated that high atmospheric air temperature, which is an important cause of water scarcity, can be converted from disadvantage to advantage by utilizing solar energy.

Now, enticing systematic civic since everywhere the world is used in green synthesis and bene t of the simple is eco-friendly with an emergent method of producing nanoparticles (NPs). The aim of a single slope single basin solar still (SBSS) have been synthesized using Silicon dioxide (SiO 2 ) nanoparticles (NPs)/leaf extract of Jatropha curcas L. (JCL) and the productivity enhancement to an evaluation for the photocatalytic treatment of the system. The synthesized of SiO 2 NPs/JCL have been characterized by XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy) prepared through EDS (X-ray Energy Dispersive Spectroscopy), studied FT-IR (Fourier Transform Infrared) spectroscopy, UV-Vis (UV-Visible spectrophotometer) was veri ed. The SiO 2 NPs/JGL was established to explain in anatase then phase phytochemicals the synthesis of leaf extracts, the NPs involved in stabilization, and was applied for the rst time to testify its potential in the SBSS process. An effect of SBSS is 82.26% during the treatment with synthesizing SiO 2 NPs/JCL successfully active for the solar still process. The SBSS has been produced the total summer distillate yield of 8.79 L/day (SiO 2 NPs /JCL), winter is 6.49, L/day (SiO 2 NPs) to over all of the system at 24 h cycle in the local climatic condition at Vijayawada, Andhra Pradesh, India. The yield of the SBSS is enhanced due to the increased absorption of solar radiation by the SiO 2 NPs/JCL, and the thermal energy is absorbed by utilization during nighttime for distillation. This is due to the convection of absorbed thermal energy to the saline water and established in a clean-green treatment solution.

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.
