Microbial Electrochemical Systems and Membrane Bioreactor Technology for Wastewater Treatment

Abstract

Membrane bioreactors (MBRs) and microbial electrochemical systems (MESs) are promising technologies for wastewater treatment and generation of electricity from organic matter. The application of MBRs is limited due to membrane fouling and high energy consumption. The novel design of the coupling system of microbial fuel cell and membrane bioreactor (MFC-MBR), which efficiently combines microbial degradation in MFCs and uses the microelectric field to reduce and mitigate membrane fouling in MBR. The fundamentals of extracellular electron transport, the performance of MFCs, different types of MBR systems, and the novelty of the MFC-MBR coupling system for wastewater treatment are reviewed.

Methanotroph biotransformation for nutrient recovery: a review of current strategies and future opportunities

“…While hollow fiber membranes offer significant advantages in gas transportation, the persistent issues of increased filtration resistance and energy consumption due to membrane fouling (Daud et al, 2023) remain challenging in membrane reactor applications. Moreover, the gas mass transfer efficiency (kLa) is not optimal due to the reactor being at the laboratory research stage.…”
