Anaerobic treatment of groundwater co-contaminated by toluene and copper in a single chamber bioelectrochemical system
Bioelectrochemistry. 2024 Apr 13;158:108711. doi: 10.1016/j.bioelechem.2024.108711. Online ahead of print.ABSTRACTAddressing the simultaneous removal of multiple coexisting groundwater contaminants poses a significant challenge, primarily because of their different physicochemical properties. Indeed, different chemical compounds may necessitate establishing distinct, and sometimes conflicting, (bio)degradation and/or removal pathways. In this work, we investigated the concomitant anaerobic treatment of toluene and copper in a single-chamber bioelectrochemical cell with a potential difference of 1 V applied between the anod...

Optimised start-up strategy for bioelectrochemical systems operating on hydrolysed human urine
This study investigated a new strategy for bioanode inoculation by mixing real hydrolysed urine with thickened waste activated sludge (TWAS) from a municipal wastewater treatment plant at different volumetric ratios. The addition of TWAS diluted the high TAN concentration of hydrolysed urine (5.2 ± 0.3 g L-1) to 2.6-5.1 g L-1, while the pH of the inoculation mixtures remained > 9 and soluble chemical oxygen demand (sCOD) at 5.6-6.7 g L-1. Despite the high pH, current generation started within 24 h for all reactors, and robust bioanodes tolerant of continuous feeding with undiluted hydrolysed urine were enriched within ...

Effect of Halomonas titanicae on fluctuating water-line corrosion of EH40 steel
Bioelectrochemistry. 2024 Apr 4;158:108703. doi: 10.1016/j.bioelechem.2024.108703. Online ahead of print.ABSTRACTThe fluctuating water-line corrosion of EH40 steel in sterile and biotic media was investigated with a wire beam electrode. When the coupons were partially immersed in the sterile medium, the position of the low water-line acted as the cathodic zone and the area below the low water-line constantly served as the main anodic zone. The thin electrolyte layers with uneven thickness promoted the galvanic current of the region below the low water-line. Different from the sterile environment, the metabolism of Halomona...
