A McGill College-led analysis group has demonstrated the feasibility of a sustainable and cost-effective solution to desalinate seawater. The tactic—thermally pushed reverse osmosis (TDRO)—makes use of a piston-based system powered by low-grade warmth from photo voltaic thermal, geothermal warmth and different sources of renewable power to provide contemporary water.
Although earlier analysis confirmed promise, this research is the primary to investigate TDRO’s thermodynamic limits. The outcomes have introduced researchers nearer to realizing the expertise which may enhance entry to water and improve the sustainability of infrastructure.
“Most desalination is done by reverse osmosis, which uses electricity to drive water through a membrane,” stated Jonathan Maisonneuve, research co-author and Affiliate Professor of Bioresource Engineering.
“The challenge with using heat is that it takes a lot of it to do what you could with a little bit of electricity. So, if we can find a way to harness existing heat from renewable sources, that could be very advantageous, because it’s so abundant,” Maisonneuve stated.
“Thermally driven reverse osmosis: thermodynamics of a novel process that uses heat for desalination and water purification,” by Saber Khanmohammadi, Sanjana Yagnambhatt, Dan DelVescovo and Jonathan Maisonneuve, was printed in Desalination…
