Stanford University scientists have learned how to purify water and get functional materials from sewers. To do this, they identified the main chemical barriers to sulfur recovery, Stanford News reported.
The scientists focused on improving the efficiency of electrochemical sulfur oxidation, which requires less energy and is easy to control.
If the process can be established and made available, it can be adapted to treat wastewater from individual buildings or areas.
In the future, the technology could be combined with other wastewater treatment methods to produce fertilizers from ammonium sulfate.
At the same time, renewable energy sources will be used as food. The authors hope that their development will make it possible to introduce technologies that restore water and valuable resources as quickly as possible.
