Researchers Discover A Way To Simultaneously Desalinate Water, Produce Hydrogen And Treat Wastewater
Combination generates pure hydrogen gas and desalination facilitated by external power supply
Fresh water and reusable energy. Humans are on a constant hunt for a sustainable supply of both. Water purification requires a lot of energy, while utility companies need large amounts of water for energy production. Their goal is to find a low-energy-required treatment technology. Researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an answer.
"Ships and their crews need energy generated on-site as well as fresh drinking water," said Ren. "Thus, the Navy is very interested in both low energy desalination and renewable energy production."
A recent study by Logan group at Penn State University also demonstrated similar findings in that the energy contained in hydrogen gas not only can offset the energy used for the desalination process but has surplus that can be used for downstream processing.
Next steps for Ren and his team will include using real wastewater to test the efficiency as well as optimizing the reactor configuration to improve system performance.
"This discovery is a milestone for our new research group," said Ren. "We are very excited about our findings and will continue working to improve the technology."
The College of Engineering and Applied Science offers programs of study in the engineering disciplines of bioengineering, civil engineering, computer science and engineering, electrical engineering, and mechanical engineering. The University of Colorado Denver offers more than 120 degrees and programs in 13 schools and colleges and serves more than 28,000 students. For more information, visit the UC Denver Newsroom.
