“…The results demonstrated the feasibility of BF-MFC integrated systems for coupling the biodegradation of gaseous contaminants with electricity generation (shown in Figure 6). 115,116 The conventional biotrickling filter was modified as MFC for the removal of volatile organic compounds (VOCs). It employed coke as packing material, which coupled with graphite rod served as anode and polyvinyl alcohol membrane as separator.…”

Microbial electrolysis cell (MEC) is a novel clean and green energy technology for biohydrogen production and simultaneously removes pollutants in terms of chemical oxygen demand, biological oxygen demand, total dissolved solids, colour, metal ions etc. from domestic, industrial and agricultural wastewater. MEC comprises of an anode and a cathode chamber separated by proton exchange membrane in which hydrogen is produced with the addition of a small electrical input (<1.2 V) due to the thermodynamic barrier. MEC is still in its inception stage and faces challenges in large-scale applications due to its design, electrodes, membrane cost, etc. In order to understand the applications of MEC, a review has been conducted to explore the various reactor configurations, including single and dual chamber, up-flow, packed bed, fluidized bed, and trickle bed reactors. In addition, basic principles, components required, MEC integrated with other bioelectrochemical system, challenges, pros and cons of reactor design have been discussed in this article. This review provides the advances and recent developments in research on MEC design, including mechanisms for real-time applications.

Biocathode microbial electrochemical systems (MESs) that remove nitrogen compounds out of wastewater are of special interest for practice. High energy-input for aeration is one of the barriers that hinder their application on a wider scope. A trickling-bed biocathode MES (TB-MES) was developed by integrating biotrickling filters with a biocathode MES. By recirculating the catholyte and sprinkling it through a spray nozzle, the system was able to achieve a reoxygenation process, which could facilitate the creation of an aerobic and anoxic environment. At an optimal recirculation rate of 200 mL min−1, the TB-MES removed 87.2 ± 2.7% of ammonium nitrogen and 79.7 ± 2.5% of total nitrogen (TN), and simultaneously achieved a maximum power density of 3.8 ± 0.3 Wm−3. Comparable performances were achieved when treating domestic wastewater, which were 84.6 ± 2.4%, 70.1 ± 4.2%, and 3.2 ± 0.2 W m−3 for ammonium nitrogen removal, TN removal, and maximum power density. Pyrosequencing analysis revealed Nitrosomonas was more abundant in the upper portion of the carbon fiber brush biocathode (CFBup, 20.4%) and Azoarcus was more abundant in the lower portion (CFBbottom, 12.6%), which was probably caused by the difference in dissolved oxygen concentration in different parts of the biocathode. The TB-MES shows great promise for domestic wastewater treatment by employing biotrickling filters for oxygen supply in biocathode MES.

Summary Resource depletion and simultaneous increase in energy demand have driven the need for alternative energy solutions, such as Bioelectrochemical systems (BESs). In the last two decades, BESs have witnessed significant research and development, however, the technology is still not commercialized. Major challenges lie with large‐scale continuous operation, limited by the understudied fluid dynamic behavior of the system as a whole, and in particular of the anolyte. A continuous flow, auto dripping bioelectrochemical reactor (AutoDriBER) was therefore developed and modeled in the present study. The optimum flow rate, under which AutoDriBER achieved 2.91 ± 0.29 V, 1.02 W/m2, and 88.29 ± 1.83% operating voltage, power density, and COD removal, respectively, was 10 mL/min. COD reduction was highest, 91.24 ± 1.52%, at 5 mL/min flow rate. The present findings form an initial step towards optimizing complex designs and overcoming limitations for the scale‐up of continuous flow bioelectrochemical reactors.
