Microbial electrolysis cells for return flow: Simultaneous nitrogen and carbon removal

[EN] The concentration of solids in secondary sludge before anaerobic digestion in a wastewater treatment plant, bring about the production of a return flow, which contains high concentrations of all the common pollutant parameters. This return flow could unfavourably affect the performance of the p...
