Sulfur amendment of zerovalent iron (ZVI) materials has been shown to improve the reactivity and selectivity ZVI toward a select group organohalide contaminants in groundwater, most notably trichloroethene (TCE). In previous studies, chemical or mechanochemical sulfidation methods were used; however, potential using sulfate-reducing bacteria (SRB) enable sulfur not closely examined. this study, lab-synthesized nanoscale (nZVI) Peerless particles (ZVIPLS) treated monoculture (D....
The Department of Defense has developed explosives with the insensitive munition 2,4-dinitroanisole (DNAN), to prevent accidental detonations during training and operations. Understanding fate transport DNAN is necessary assess risk it may represent groundwater once new ordnance routinely produced used. Experiments ferrous iron or anthrahydroquinone-2,6-disulfonate (AH2QDS) were conducted from pH 6.0 9.0 initial concentrations 100 μM. was degraded by 1.2 mM Fe(II) at 7, 8, 9, rates increased...
Granular activated carbon (GAC) effectively removes hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) from groundwater but generates RDX-laden GAC that must be disposed of or regenerated. Batch reactors containing to which RDX was preadsorbed were used in experiments test the potential for adsorbed reduction and daughter product formation using (i) chemically reduced anthrahydroquinone-2,6-disulfonate (AH2QDS), (ii) resting Geobacter metallireducens strain GS-15, (iii) a combined system AQDS...
Floods have the potential to resuspend polycyclic aromatic hydrocarbons (PAHs) laden sediments and potentially impact drinking water intakes. This work identifies optimal operating conditions for PAH removal from using a combined permanganate (Mn(VII))/bisulfite advanced oxidation process (AOP). PAHs in aqueous solutions containing humic acid (HA) were treated combination of bisulfite at different molar ratios. Results showed that Mn(VII)/bisulfite AOP was an effective method remove priority...
Efforts addressing sludge management, food security, and resource recovery have led to novel approaches in these areas. Electrically assisted conversion of stands out as a promising technology for sewage valorization, producing nitrogen phosphorus-based fertilizers. The adoption this technology, which could lead fertilizer circular economy, holds the potential catalyze transformative change wastewater treatment facilities toward process intensification, innovation, sustainability. This paper...
Abstract According to the National Science Foundation, Center for and Engineering Statistics (NSF, NCSES, 2015), women represent 50.2% of US Resident population, 12.9% workforce, 24.7% mathematics CS work force. The percentage employed females in science engineering is 47.6% includes full-time, part-time, post doc employment between ages 16-75 2015). A 2015 News World Report article notes that despite a national focus supported by federal government funding encourage minorities study...
