“…Figures 2A and 2B show a kind of glass-covered greenhouse (also called solar still). [60][61][62][63][64][65] At night, the window or the glass cover is opened and the desiccants capture the moisture in the feed air by natural or forced convection. During daytime, the sorber absorbs the incident solar radiation and thus the desiccant temperature increases.…”

Even if people live in an arid desert, they know that plenty of water exists in the air they breathe. However, the reality tells us the atmospheric water cannot help to slake the world's thirst. Thus an important question occurs: what are the fundamental limits of atmospheric water harvesting that can be achieved in typical arid and semi-arid areas? Here, through a thorough review on the present advances of atmospheric water-harvesting technologies, we identify the achievements that have been acquired and evaluate the challenges and barriers that retard their applications. Lastly, we clarify our perspectives on how to search for a simple, scalable, yet cost-effective way to produce atmospheric water for the community and forecast the application of atmospheric water harvesting in evaporative cooling, such as electronic cooling, power plant cooling, and passive building cooling.

“…The results revealed that appropriate glass thickness (3mm), the air gap elevation (0.22m), tilt angle (30°), and single glazing are the design criteria for maximum production. During the experiment, the highest amount of freshwater generated was (200 mL/Kg of desiccant/day) (M. Kumar & Yadav, 2015). William et al, designed and built a trapezoidal prism absorber with 4 fiberglass surfaces (Fig.…”

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.

“…Currently, typical desiccants including: hygroscopic salts [8,9] , polymers [10][11][12] , zeolites [13] and silica gel [14] . However, they are suffering from drawbacks of slow kinetics (for salts), or hard regeneration (for polymers), or weak adsorption capacities (for zeolite and silica gel).…”

Atmospheric water harvesting based on vapor adsorption is a newly emerged and potential technology to supply portable water for arid areas. To efficiently harvest vapor from the air, sorbents are required to have considerable adsorption capacity, easy regeneration and high stability.With the advantages of porous structure, tunable pore size and tailorable hydrophilicity, metal-organic frameworks (MOFs) have demonstrated excellent performance in vapor adsorption and water generation. In this review, we first discuss the degradation mechanisms of MOFs exposed to water and summarize the structure-stability relationship; by centering on the adsorption isotherms, the connection between the structure of MOFs and the water adsorption property is illuminated; finally, some prospects are suggested in order to push forward the progress of this technology.
