Powering biological nitrogen removal from the environment by geobatteries

Geobatteries are redox-active substances that can take up, store, and release electrons reversibly. Provided that their redox activity can be maintained by fluctuations of oxidizing and reducing redox conditions, geobatteries could also improve the performance of engineered systems, such as in biolo...

Zusammenfassung:Geobatteries are redox-active substances that can take up, store, and release electrons reversibly. Provided that their redox activity can be maintained by fluctuations of oxidizing and reducing redox conditions, geobatteries could also improve the performance of engineered systems, such as in biological nitrogen removal from wastewater or constructed wetlands.
