Abstract
In the context of global adaptation to climate change, the demand for water, especially drinking water, becomes a serious issue that needs to be studied to find feasible and economical solutions. Many available technologies have been applied to produce drinking water such as filtration of groundwater or seawater. However, the implementation of these technologies is feasible or not depending on specific nature as well as socio-economic conditions. For the drought regions where there is no seawater and lack of groundwater, moisture separation technology becomes a feasible solution. A system to extract the water from moisture has been designed, fabricated and installed to provide 10 liters of drinking water per day. As the system operates; it can produce around 2.1 liters of drinking water per hour; and consume 1.8 kW of electricity. The system has been designed to be able to use two types of power sources: one from solar energy (main source) and the other from the national grid (auxiliary source).
