Two-side cathode microbial electrolysis cell for nutrients recovery and biogas upgrading
Here a three-chamber microbial electrolysis cell (MEC) has been developed to couple the CO 2 removal from a gas mixture to the ammonium nitrogen recovery. The here proposed MEC adopted an innovative two-side cathode configuration, where two identic cathodic chambers are connected in parallel by a titanium wire and separated from an intermediate anodic compartment by an anion and a cation exchange membrane (AEM and CEM).
