| Batch Reverse Osmosis - a new breakthrough |
| 2021-05-14 |
| [Purdue University] Warsinger's lab has used this double-acting batch development to fuel several new advances in desalination. Abhimanyu Das, a Purdue Ph.D. student in mechanical engineering, has published research describing a variant of the process called "batch counterflow reverse osmosis." By recirculating certain concentrations of water on both sides of the membrane, Das' process is shown to be the most energy-efficient desalination process for high-salinity water, while requiring fewer components. And Purdue master's student Michael Roggenburg has published research showing that a combination of batch reverse osmosis and renewable energy could conceivably deliver fresh water to the entire 1,954-mile border between the U.S. and Mexico. "Water security is a huge issue around the world, which I've spent my whole career working on," Warsinger said. "These results with batch reverse osmosis are really exciting. If we bring the cost down just a little bit, then desalination becomes a viable option for more places. It could be transformative." |
