United Arab Emirates University Granted Patent for an Innovative Low-Energy DesalinationSystem
Researchers at the United Arab Emirates University have made an unprecedented scientificadvance that has the potential to revolutionize the water desalination industry.
Scientists in the university¡¯s National Water and Energy Center have invented a newdesalination system that dramatically reduces energy consumption during the desalinationprocess.
Traditional desalination systems involve processes of heating, re-condensation, andevaporation as well as the use of fine membranes that allow the water to pass withoutsalt. These processes, including Thermal and Reverse Osmosis desalination systemsconsume vast amounts of energy.
In contrast, UAEU scientists made a direct applicationof the theoretical principles of thermodynamics and the conservation of mass and energyto discover that water can be desalination by using a combination of high and lowpressures.
Saline water is first pushed at high pressure through a pipeline with the venturidevice in which the speed of the water is increased and its pressure is reduced toallow for evaporation with no or minimum heating. The water is then turned into steamby containing it at very low pressure. After re-condensation, the water is fully desalinated.
The low-energy desalination system has been granted a patent by the US Patents andTrademarks Office. This adds to the total of more than 178 patents obtained by scientistsat the United Arab Emirates University in areas of national priority. It is furtherevidence of the support provided by the university for the sustainable developmentplans of the United Arab Emirates.
