The combination of hydrophobic membranes and microbial electrolysis cells (MEC) was assessed in two different configurations order to recover ammonia from anaerobically digested pig slurry. Polytetrafluorethylene (PTFE) were inserted both an H-type three-chamber cell (MEC-H) a two-chamber sandwich configuration MEC (MEC-S), fitted with cationic exchange membrane (CEM) dividing the anode cathode...

Electrohydrogenesis is a bio-electrochemical process where organic material is microbially oxidized to protons and electrons, which in turn are reduced to form hydrogen gas (H2). The reactor in which these reactions occur is termed a microbial electrolysis cell (MEC). The microorganisms that colonize the anode are known as electricigens and behave as biological catalysts, significantly reducing...

Microbial fuel cell and microbial electrolysis cell are two major types of microbial electrochemical cells. In the present study, we governed modeling of these systems by concentrating on the simulation of bioelectrochemical reactions in both biofilm and anolyte and considering the effect of pH on the microbial growth. The simulation of microbial fuel and electrolysis cells can be described by ...

Applying microbial electrochemical technologies for the treatment of highly saline or thermophilic solutions is challenging due to the lack of proper inocula to enrich for efficient exoelectrogens. Brine pools from three different locations (Valdivia, Atlantis II and Kebrit) in the Red Sea were investigated as potential inocula sources for enriching exoelectrogens in microbial electrolysis cell...

In this work, the design of hardware architecture to implement an algorithm for optimizing Hydrogen Productivity Rate (HPR) in a Microbial Electrolysis Cell (MEC) is presented. The HPR MEC maximized by golden section search conjunction with super-twisting controller. development digital implementation step optimization was developed Very High Description Language (VHDL) and synthesized Field Pr...

Bioelectrochemical systems (BESs) are regarded as effective green technologies for wastewater treatment, with low associated energy costs. This work studies the influence of cathode pH and operational mode, microbial fuel cell (MFC) or electrolysis (MEC), on electrocatalytic hydrodechlorination (ECH) 2,4-dichlorophenol (2,4-DCP) in an abiotic cathode. When operating MFC, results showed that mor...

BACKGROUND Bioelectrochemical systems have been considered a promising novel technology that shows an enhanced energy recovery, as well as generation of value-added products. A number of recent studies suggested that an enhancement of carbon conversion and biogas production can be achieved in an integrated system of microbial electrolysis cell (MEC) and anaerobic digestion (AD) for waste activa...
