Promising technologies for converting wastewater into drinkable water produce a chemical compound that can be toxic, corrosive and malodorous. An analysis of one possible solution reveals ways to optimize it for maximum energy efficiency, pollutant removal and resource recovery.
One person’s wastewater is another person’s treasure. A new Stanford University study paves the way to mining sewage for valuable materials used in fertilizers and batteries that could someday power smartphones and airplanes.
The analysis, published recently in ACS ES&T...
