Journal ArticleDOI
Performance of a pilot-scale continuous flow microbial electrolysis cell fed winery wastewater
Roland D. Cusick,Bill Bryan,Denny S. Parker,Matthew D. Merrill,Maha Mehanna,Patrick D. Kiely,Guangli Liu,Bruce E. Logan +7 more
TL;DR: Results show that inoculation and enrichment procedures are critical to the initial success of larger-scale systems and better methods will be needed to isolate hydrogen gas produced at the cathode.
Journal ArticleDOI
Using microbial desalination cells to reduce water salinity prior to reverse osmosis
Maha Mehanna,Tomonori Saito,Jingling Yan,Michael A. Hickner,Cao Xiaoxin,Xia Huang,Bruce E. Logan +6 more
TL;DR: In this paper, the authors investigated the use of an air-cathode microbial desalination cell (MDC) as an RO pre-treatment method using a new type of air cathode MDC containing three equally sized chambers.
Journal ArticleDOI
Microbial Electrodialysis Cell for Simultaneous Water Desalination and Hydrogen Gas Production
TL;DR: The advantage of this MEDC system compared to a microbial fuel cell approach is that the potentials between the electrodes can be better controlled, and the hydrogen gas that is produced can be used to recover energy to make the desalination process self-sustaining with respect to electrical power requirements.
Journal ArticleDOI
Effect of nitrogen addition on the performance of microbial fuel cell anodes.
Tomonori Saito,Maha Mehanna,Xin Wang,Roland D. Cusick,Yujie Feng,Michael A. Hickner,Bruce E. Logan +6 more
TL;DR: It is demonstrated that a small amount of nitrogen functionalization on the carbon cloth material is sufficient to enhance MFC performance, likely as a result of promoting bacterial adhesion to the surface without adversely affecting microbial viability or electron transfer to thesurface.
Journal ArticleDOI
Role of direct microbial electron transfer in corrosion of steels
TL;DR: In this article, the bacterium Geobacter sulfurreducens is shown to increase the free potential of 304 L stainless steel up to 443 mV in only a few hours, which represents a drastic increase in the corrosion risk.
