A microbial desalination cell (MDC) is a new approach to bioelectrochemical systems. It provides more sustainable way electrical power production, saltwater desalination, and wastewater treatment at the same time. This study examined three operation modes of MDC: chemical cathode, air biocathode MDC, give clear sight this system's performance. The experimental work results for these were record...

The technology is based on microbial fuel cells (MFCs), which use microorganisms as catalysts to convert chemical energy to electrical energy. The paper’s authors, including Bruce Logan of Pennsylvania State University and Xiaoxin Cao of Tsinghua University (China), are among the small group of researchers worldwide trying to improve MFCs—or bioelectrochemical systems, as they are beginning to ...

A new microbial desalination cell with capacitive adsorption capability (cMDC) was developed to solve the ion migration problem facing current MDC systems. Traditional MDCs remove salts by transferring ions to the anode and cathode chambers, which may prohibit wastewater beneficial reuse due to increased salinity. The cMDC uses adsorptive activated carbon cloth (ACC) as the electrodes and utili...

Abstract In view of increasing threats arising from the shortage fresh water, there is an urgent need to propose sustainable technologies for exploitation unconventional water sources. As a derivative microbial fuel cells (MFCs), desalination cell (MDC) has potential desalinating saline/brackish while simultaneously generating electricity, as well treating wastewater. Therefore, it worth invest...

► Bacteria generate electricity while oxidizing organic matter in wastewater. ► Electricity produced can be used to desalinate salt water without any

Mineral carbonation can be used for CO2 sequestration, but the reaction rate is slow. In order to accelerate mineral carbonation, acid generated in a microbial electrolysis desalination and chemical-production cell (MEDCC) was examined to dissolve natural minerals rich in magnesium/calcium silicates (serpentine), and the alkali generated by the same process was used to absorb CO2 and precipitat...

A recirculation microbial desalination cell (rMDC) was designed and operated to allow recirculation of solutions between the anode and cathode chambers. This recirculation avoided pH imbalances that could inhibit bacterial metabolism. The maximum power density was 931±29mW/m(2) with a 50mM phosphate buffer solution (PBS) and 776±30mW/m(2) with 25mM PBS. These power densities were higher than th...
