Water is one such element that the human being cannot live without. In the last couple of decades due to global warming and unprecedented weather changes water has become scarce. Transportation of water to villages and desert areas cost a fortune and is not practical. In this study, water has been extracted from various desiccant materials while also employing the help of concentrated solar power. The desiccant materials that have been used are Silica Gel, Activated Clay and Activated Alumina. Activated Clay is a mixture of different elements which can be used as a desiccant material. These desiccants tend to adsorb the water present in the atmospheric air that is around it and when regeneration occurs it is unconfined as water vapour droplets. For the present work, a Scheffler-type concentrator along with a short cylinder type receiver is used as the solar radiation heat source for the regeneration process. Solar radiation or rather beam radiation is directed at the receiver that contains the desiccant material. It is observed from the experimental study that silica crystals produced 142 ml/kg/day of water whereas activated alumina and activated clay produced 100 ml/kg/day and 48 ml/kg/day of water respectively on a clear sunny day.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
