Evolutionary trends and development of constructed wetland coupled microbial fuel cell: A decade of development.

Constructed wetland coupled microbial fuel cells (CW-MFC) have gained considerable attention as an innovative sustainable technology for simultaneous wastewater treatment and bio-electricity generation since its inception in 2012. This study, which employed bibliometrics of research articles and patent analysis, is a comprehensive investigation into the evolutionary trend and development status of CW-MFC. We analyzed 85 patents and 247 research articles using structured and unstructured data.

Application of ZIF-8 nanocomposite membrane in microbial desalination cells for simultaneous heavy metal removal and biofouling prevention.

Microbial desalination cells (MDC) syndicate the advantage of physical separation by using membranes to create conditions required for Bioelectrochemical processes for the treatment of various domestic and industrial wastewater, while simultaneously desalinating saline water and generating bioenergy. However, since the introduction of this technology, heavy metal removal has been a challenge, and membrane fouling has become a major bottleneck limiting the optimum performance and efficiency of this technology. This study incorporated the use of ZIF-8 nanocomposite membrane via phase inversion mechanism in MDC for simultaneous heavy metal removal and membrane biofouling prevention.

Comparative Studies of Recirculatory Microbial Desalination Cell-Microbial Electrolysis Cell Coupled Systems.

The recirculatory microbial desalination cell-microbial electrolysis cell (MDC-MEC) coupled system is a novel technology that generates power, treats wastewater, and supports desalination through eco-friendly processes. This study focuses on the simultaneous efficient removal of Fe and Pb in the MEC and ammonium ions in the MDC. It also evaluates the performances of dual-chambered MEC (DCMEC) and single-chambered MEC (SCMEC), coupled with MDC with Ferricyanide as catholyte (MDCF) in heavy metals (Pb and Fe) removal, in addition to the production of voltage, current, and power within a 48-h cycle.

Assessing the factors influencing the performance of constructed wetland-microbial fuel cell integration.

Constructed wetland coupled microbial fuel cell (CW-MFC) systems integrate an aerobic zone and an anaerobic zone to treat wastewater and to generate bioenergy. The concept evolves based on the principles of constructed wetlands and plant MFC (one form of photosynthetic MFC) technologies, of which all contain plants. CW-MFC have been used in a wide range of application since their introduction in 2012 for wastewater treatment and electricity generation.

Performance of Exoelectrogenic Bacteria Used in Microbial Desalination Cell Technology.

The tri-functional purpose of Microbial Desalination Cell (MDC) has shown a great promise in our current scarcity of water, an increase in water pollution and the high cost of electricity production. As a biological system, the baseline force that drives its performance is the presence of exoelectrogens in the anode chamber. Their presence in the anodic chamber of MDC systems enables the treatment of water, desalination of seawater, and the production of electrical energy.
