MIT’s Solar-Powered Desalination Machine Could Help Drought-Stricken Communities
Called a “photovoltaic-powered electrodialysis reversal system,” the technology recently won the top $140,000 Desal Prize from the U.S. Department of Interior (USID) that recognizes innovators who create cost-effective, energy efficient and environmentally sustainable desalination technologies that can provide potable water for humans and water for crops in developing countries, the USID announced.
The USID said that the MIT-Jain system is designed for low-energy consumption and helps reduce costs for underdeveloped areas that do not have easy access to electricity. “By 2050, global water demand is expected to increase by 55 percent, and 70 percent of global water use occurs in food production,” said Christian Holmes, USAID’s Global Water Coordinator, in a statement. “The Desal Prize was developed to supply catalytic funding to capture and support the innovative ideas and new technologies that could have a significant impact.”
Jain Irrigation Systems noted that with this technology, water recovery is above 90 percent and the 5-10 percent reject concentrate is dried in a solar pond without creating any environmental hazard. It also removes hardness as well as salts and chemicals, pesticides, fertilizers as well as micro-organisms.
“This technology has the potential to bring agriculture to vast barren lands using brackish water,” said Richard Restuccia, Jain’s vice president of Landscape Solutions…
