The Kingdom of Bahrain falls geographically in one of the driest regions in the world. Conventional fresh surface water bodies, such as rivers and lakes, are nonexistent and for water consumption, Bahrain prominently relies on the desalination of sea water. This paper presents an ongoing project that is being pursued by a group of student and their advising professors to investigate the viability of extracting water from air humidity. Dehumidifiers have been utilized as water extraction devices. Those devices have been distributed on six areas that were selected based on a rigorous geospatial modeling of historical meteorological data. The areas fall in residential and industrial neighborhoods that are located in the main island and the island of Muharraq. Water samples have been collected three times every week since May of 2016 and the collection process will continue until May of 2017. The collected water samples have been analyzed against numerous variables individually and in combinations including: amount of water collected per hour versus geographical location, amount of water collected per hour versus meteorological factors, suitability of collected water for potable human consumption, detection of air pollution in the areas of collection and the economy of this method of water collection in comparison to other nonconventional methods. An overview of the completed analysis results is presented in this paper.

Abstract. Water is of vital importance for all species including mankind. In recent years water shortage has aroused wide concern because it is also the root of many other serious social problems, such as poverty, health problems, and national security. Water harvesting from air has long been seen as a potential solution to address this crisis. Traditional method based on air refrigeration can yield considerable water production while at the cost of tremendous electricity consumption, thus not eco-friendly. Recent studies focus on the adsorption-desorption cycle of substances with high water uptake capability, such as metal-organic frameworks (MoFs), which can exploit low grade heat resources, mainly sunlight, thus requiring no extra power input. While the working cycle of this method has been proved time consuming, typically for hours. Here a compromising low energy-consuming solution is proposed to shorten the time span of a single cycle by using ceramic heater and semiconductor chilling plate powered by solar cells. Results show that the new solution can efficiently shorten the duration of this process, thus promoting the total yield of water harvesting equipment.

“…by modifying the isotherms of the material, by selective water sorbent (SWS) and using thick corrugated layers. Abualhamayel and Gandhidasan (1997) studied analytically the method of production of fresh water using a liquid desiccant. It was proposed that at a given set of operating condition, it was possible to obtain 1.90 kg of water per m 2 .…”

In this paper, experiments have been performed in order to determine the quantity of water produced from the atmospheric air using different desiccant materials named Silica gel, Activated alumina and Molecular sieve 13 X. On the bases of experimental results, a correlation is derived among the different temperatures and water production using Central Composite Design (CCD) of Response Surface Methodology. A newly designed solar glass desiccant box type system (SGDBS), three in number, has been used. Design parameters for the production of water has been taken as depth of material from the glass is 0.22 m, inclination in angle as 30°, effective thickness of glass as 3 mm and number of glazing as single. It has been found experimentally that the maximum quantity of water produced by Silica gel, Activated alumina and Molecular sieve 13 X is 160, 20 and 35 ml/kg/day, respectively. Whereas theoretically, value of water produced by the Silica gel, Activated alumina and Molecular sieve 13 X is 600, 28 and 60 ml/kg/day, respectively.
