N2 - Wastewater treatment using bioelectrochemical systems (BES) can be
considered as a technology finding application in versatile areas such
as for renewable energy production and simultaneous reducing
environmental problems, biosensors, and bioelectrosynthesis. This review
paper reports and critically discusses the challenges, and advances in
bio-electrochemical studies in the 21st century. To sum and critically
analyze the strides of the last 20+ years on the topic, this study first
provides a comprehensive analysis on the structure, performance, and
application of bioelectrochemical systems, which include Microbial Fuel
Cells (MFC), Microbial Electrolysis Cells (MEC) and Microbial
Desalination Cells (MDC). We focus on the effect of various parameters,
such as electroactive microbial community structure, electrode material,
configuration of bioreactors, anode unit volume, membrane type, initial
COD, co-substrates and the nature of the input wastewater in treatment
process and the amount of energy and fuel production, with the purpose
of showcasing the modes of operation as a guide for future studies. The
results of this review show that the bio-electrochemical systems have
great potential in reducing environmental pollution, purifying
saltwater, and producing energy and fuel. At a larger scale, it aspires
to facilitate the path of achieving sustainable development and
practical application of BES in real-world scenarios.
