  • Water generation from atmospheric air by using desiccant materials- nature-based solution – a review

    Purpose This paper aims to provide a critical review of water generation from atmospheric air by using desiccant materials. Over the past few years, there has been very high stress on water scarcity, especially in Asian and African countries. Because of this insecurity, many countries are focusing on their research in the field of water technologies. Water generation from atmospheric air by using desiccant materials is one of the techniques among the air-to-water generators (AWGs). Design/methodology/approach A structured and systematic literature review has been presented to observe and understand the past trend/patterns in the field of water generation from atmospheric air by using desiccant materials. To understand the water generation technologies based on desiccant materials, the research papers from the years 1987 to 2022 have been studied and included. Findings The properties of the different and most probable desiccant materials in the field of AWGs have been discussed. A detailed review of testing reports of collected water samples has also been presented in tabular form. Finally, the economic analysis has been done and future prospects have been discussed. It is also found that the capacity of solid desiccant materials to adsorb the water is less as compared to liquid desiccant materials. But, the adsorption capacity can be improved by using composite desiccant materials. Originality/value The uniqueness of this manuscript lies in the compiling and examination of the existed published research papers, including variables such as author, year and geographical location, experimental/simulative, types of desiccant material, type of setup, desiccant material type and quantity and type of concentrator. This manuscript provides critique to the empirical and conceptual research in AWG technologies and also stimulates researchers to explore the topic very carefully.


  • Extraction of water particles from atmospheric air through a Scheffler reflector using different solid desiccants

    ABSTRACT In this article, an attempt has been made to extract water particles from atmospheric air by using silica gel, molecular sieve13× and activated alumina. The cycle consists of two phases, first is a nocturnal phase (night) and other is a diurnal phase (day time). In the nocturnal phase, adsorption process takes place, regeneration and condensation processes take place in the diurnal phase. The water production rate depends upon the regeneration rate of the material. A newly designed fixed focus Scheffler reflector of surface area 1.54 m2 is used to regenerate the desiccant materials. The water produced from this method is clean and can be used for potable purposes. The production rate of water is 43, 38 and 155 ml/day from 1 kg each of the molecular sieve, activated alumina and silica gel, respectively; furthermore, the adsorption rate, regeneration rate and cost analysis are also carried out.
