Water desalination, water purification, sub-atmospheric, humidification-dehumidification
Existing humidification-dehumidification desalination processes are not particularly energy efficient or productive.
In this innovative technology, the pressure inside the humidifier and dehumidifier is lower than the atmospheric pressure during humidification dehumidification processes. As pressure of air decreases, the water vapor content in the humidified air increases, hence providing increased production of the fresh water.
