Desalination tech uses CO2 to tap into municipal wastewater as alternative freshwater source
Turning cities' wastewater into usable freshwater is an environmental win.
Engineering the system to be more energy efficient makes a good idea even better.
Using a greenhouse gas—carbon dioxide—to power the process?
It's an approach that’s potentially transformational, according to Rossin College professor Arup SenGupta (pictured), a world-renowned researcher, educator, author, and and inventor who has dedicated his career to addressing problems relating to the lack of safe drinking water.
"Municipal wastewater treatment plants in large cities are insulated from the negative effects of climate change, and treated wastewater can serve as a potential water source, provided appropriate sustainable and cost-effective technologies are available," he says.
