Sustainability of Atmospheric Water Harvesting in the Remote Areas

Abstract

Atmospheric water harvesting appears to be a potential way to address water scarcity, particularly in locations where liquid water is scarce. Rainwater harvesting (RWH) is a low-cost, easy approach that requires little special expertise or understanding and has numerous advantages in remote areas. The purpose of this chapter is to examine various types of sustainable atmospheric water harvesting techniques. AWH appears to be a potential methodology for decentralized water production, overcoming the difficulties of long-term conveyance and supply of fresh drinking water in remote areas. Structural designs of innovative materials enable moisture harvesters to have desirable characteristics including high water uptake, durable recyclability, and easy collection of water, accelerating the next generation development of AWH. In this chapter, we first show the sorption mechanism for moisture-harvesting materials, including absorption and adsorption, and then review essential needs and moisture harvester design concepts. The development of an atmospheric water harvester that can generate water irrespective of geographical location, humidity level, low cost, and can be manufactured using local materials is the primary goal of all methods.
