Systems and methods are disclosed for extraction of freshwater from ambient air in regions of extremely hot and humid climates, for supply of drinking water and freshwater for small to large groups of people in remote and isolated areas or wherever freshwater resources are not conveniently accessible. Compact mobile units are disclosed to provide freshwater and drinking water for resort areas, to passengers on land and sea vehicles, in situations of emergency, and to areas of water shortage. The art of adaptation of commercial dehumidification units is taught in design and construction of apparatus for production of freshwater and drinking water. Preparation of drinking water included ultraviolet disinfection, ozone treatment, and/or chlorine addition; activated carbon and ion exchange filters; and adding of fluorine, air/oxygen to refresh the water storage units, and minerals for taste and health provisions. For energy economy and use of independent electric power supply, the produced water may flow under gravitational forces entirely or with the assistance of small boasting pumps. Lukewarm, hot, cold, and/or cold carbonated drinking water are provided as well as freshwater for other usage. |
