Source water protection in areas of shale gas development encompasses identifying that are the most vulnerable to groundwater quality deterioration due spills natural production wastewater. This study uses density-dependent flow and transport code TOUGH2 quantify time distance travel saline wastewater plumes for different hydrogeological settings Northeast British Columbia. The models were desi...

introduction water scarcity has led to the search for alternative water resources. one solution is the recycling of wastewater for irrigation. wastewater treatment is often based on biological systems such as activated sludge or other engineered units in urban areas. in rural areas, low-cost, environmentally-friendly alternative treatments such as constructed wetlands (cw), are more common. cws...

Halophiles are key microorganisms to potentially overcome the salinity-induced limitation in anaerobic bioremediation of organic pollutants and energy recovery when using conventional inoculums. This study aimed enrich halophiles from hypersaline sediment optimize their use as alternative inoculum for fermentative hydrogen production. Batch assays 15 combinations (i.e., pH 6–10, salinity 10–70 ...

The spread of antibiotic-resistant bacteria is a growing problem and a public health issue. In recent decades, various genetic mechanisms involved in the spread of resistance genes among bacteria have been identified. Integrons - genetic elements that acquire, exchange, and express genes embedded within gene cassettes (GC) - are one of these mechanisms. Integrons are widely distributed, especia...

The fish processing sector contributes serious organic pollution loads and high salinity to receiving waters. This research aimed to study the effect of salt (NaCl) concentration on the treatment efficiency of fish processing wastewater in a continuous flow system by natural biodegradation. This research also focused on the use of a laboratory-scale bioreactor, which is operated in an aerobic c...

Multilayer heterojunction SbSn/CoTi/Ir anodes, which consist of Ir0.7Ta0.3O2 bottom layers coated onto a titanium base, Co-TiO2 interlayers, and overcoated discrete Sb-SnO2 islands, were prepared by spray pyrolysis. The Ir0.7Ta0.3O2 bottom layer serves as an Ohmic contact to facilitate electron transfer from semiconductor layers to the Ti base. The Co-TiO2 interlayer and overcoated Sb-SnO2 isla...

► Microbial salinity-reduction electrolysis cells (MSCs) can treat salinewastewater. ► In MSCs, organic matter and salt ions were removed simultaneously. ► Ion-exchange membranes were not damaged for three months in MSCs. ► Exoelectrogens can generate high currents with salinities up to 36 g/L TDS. ⁎ Corresponding author.
