Abstract—Bio-electrochemical anaerobic digestion (AD) is
one of the most recent advancement in anaerobic treatment
processes. Microbial electrolysis cells (MECs) are used for
bio-electrochemical treatment, where the supplied external
power is used to enhance the performance of AD. Multiple
studies have investigated the viability of MECs under various
operating parameters and for different organic wastes. The
present paper aims at reviewing the latest literature regarding
bio-electrochemical enhanced AD through MECs. It was
concluded that MEC reactors significantly enhance AD
performance under different supplied voltages, temperatures,
electrodes configuration, as well as other operating parameters.
Based on the compiled literature, further comprehensive life
cycle assessment of MECs is recommended prior to any
full-scale implementation.
Index Terms—Anaerobic digestion, bio-electrochemical
