ABSTRACT Long‐term stable operation of bioelectrochemical systems (BES) presupposes the avoidance mass transfer limitations electroactive biofilm. Excessive pH‐gradients from bulk to electrode interface or substrate biofilm are known diminish electrical performance BES. In this study impact morphology a mixed‐species cultivated on microbial electrolysis cell (MEC) was investigated identify optimal for real‐life applications in wastewater treatment. Noninvasive monitoring by means optical coherence tomography and an industrial sensor allowed real‐time evaluation The maximum current density approximately 3.5 A/m² found mean thickness range 100–150 µm, beyond which thicker biofilms caused limitations. Along with local detachment continuous decline efficiency demonstrates need active control adjust thickness.
