Assessment of recirculation batch mode of operation in bioelectrochemical system; a way forward for cleaner production of energy and waste treatment

Upscaling bioelectrochemical systems needs a proper operational mode to integrate them to the units operating in pilot and industrial scales. This study conducted a comprehensive investigation on combining the advantages of conventional batch and continuous operational modes in form of a simple and...
