extract water from air

Abstract

Water vapor is extracted from air in a process in which water vapor from large volumes of air is concentrated by absorption into a small volume of hygroscopic liquid (14), from which it is recovered by passage through a selective layer (12).

Description

technical field [0001] The present invention generally relates to a structure suitable for extracting water from air. Background technique [0002] The world's supply of high-quality drinking water is significantly insufficient. According to official estimates, about 1'5 million people in the world do not have adequate quality drinking water. Every 8 seconds a child dies from drinking polluted water. [0003] There is an urgent need to provide drinking water for humans, especially in arid regions. To compensate for the lack of rainwater, various techniques have been introduced. In coastal areas, water is obtained at high cost from seawater by multi-stage distillation or by reverse osmosis. [0004] Producing water on an industrial scale requires high investment in infrastructure and operation as well as energy. These systems cannot be used inland, where seawater and brackish water are not available. Water from large-scale production must be distributed through a piping...
