Physico-chemical characterization of water obtained by condensation of moisture from an atmospheric water generator in Tunisia

Résumé

Abstract The availability of water resources is an uphill struggle for many countries in the world since it guarantees environmental, agronomic, food, economic competitiveness, and public health. Water scarcity is becoming a headache worldwide, and this solution has become a must. The technique of condensation of moisture through the water vapor contained in the atmosphere is developed to generate water. Therefore, the purpose of our work is an additional source of water through the process of condensation of moisture to supply drinkable water intended for consumption. In this context, a condensation prototype Kumulus has been adapted. In those studies, tests conducted in different regions of Tunisia to determine the physicochemical quality of the produced water. To improve the quality of the water obtained, a treatment process has been implemented. Dew quality is assessed according to the standards of potable water quality. Ion concentration meets the requirements of the World Health Organization, European Directives, and Tunisian Drinking Water Guidelines. Costs and economic aspects are also considered. The results of water chemistry can therefore be viewed as a "footprint" of regional and local air composition. This project aims to produce water in areas where access to water is difficult. This technique provides an alternative to other sources of drinking water.
