Bioretention vegetation contributes to both the hydrologic and pollutant removal functions of bioretention.
Electrokinetic desalination of brackish water and associated challenges in the water and energy nexus
This article presents the challenges and opportunities of electrokinetic desalination for brackish water and its recent development and prospective.
A review of sanitation technologies to achieve multiple sustainable development goals that promote resource recovery
This study critically reviews literature and provides material flows of nitrogen, phosphorus, and carbon to determine the ability of existing sanitation technologies and strategies that can be deployed to safely recover resources and thus achieve multiple sustainable development goals.
Aerobic granulation for future wastewater treatment technology: challenges ahead
Aerobic granules were discovered around 20 years back.
Cyto- and geno-toxicity of 1,4-dioxane and its transformation products during ultraviolet-driven advanced oxidation processes
Ultraviolet-driven advanced oxidation processes (UV/AOPs) are integral steps in water reuse treatment trains.
Capacitive deionization for nutrient recovery from wastewater with disinfection capability
This study demonstrates that capacitive deionization can be effectively used for the removal and recovery of dominant nitrogen (ammonium) and phosphorus (phosphate salts) species present in wastewater.
Role of microbial cell properties on bacterial pathogen and coliphage removal in biochar-modified stormwater biofilters
Bacterial pathogens and pathogen indicators suspended in stormwater are removed to a greater extent in biochar-augmented sand biofilters than sand biofilters; the processes governing the removal are distinct.
Effect of pyrolysis on the removal of antibiotic resistance genes and class I integrons from municipal wastewater biosolids
Biosolids carry a substantial portion of antibiotic resistance genes (ARGs) leaving wastewater treatment plants. Pyrolysis substantially reduces ARGs in biosolids.
Urine-powered synergy of nutrient recovery and urine purification in a microbial electrochemical system
Energy in urine was extracted to synergize the in situ urine purification and nutrient recovery with net electricity production via a microbial electrochemical system named U-Power.
Recyclable amine-functionalized magnetic nanoparticles for efficient demulsification of crude oil-in-water emulsions
Produced water from the oil and gas industry often contains stable crude oil-in-water emulsions that are typically difficult to treat with conventional separation methods.
Metaldehyde removal from drinking water by adsorption onto filtration media: mechanisms and optimisation
Trace micropollutants should be removed during drinking water production without increasing the disinfection-by-product formation potential or energy demand of the treatment process.
The fate of dichloroacetonitrile in UV/Cl2 and UV/H2O2 processes: implications on potable water reuse
The findings have important implications for the control of preformed DBPs by subsequent UV-AOPs for potable water reuse.
Potential formation of mutagenicity by low pressure-UV/H2O2 during the treatment of nitrate-rich source waters
LP-UV/H2O2 treatment of NOM-containing synthetic waters led to nitrite, nitrophenol and measurable but not mutagenic Ames responses in the presence of nitrate, where the NOM type affected the response levels.
Impact of upstream chlorination on filter performance and microbial community structure of GAC and anthracite biofilters
Dechlorination in GAC biofilters leads to greater bioactivity and growth of a diverse microbial community.
Propidium monoazide pretreatment on a 3D-printed microfluidic device for efficient PCR determination of ‘live versus dead’ microbial cells
A microfluidic chip for differentiating live versus dead cells was designed and tested experimentally with lab and environmental samples.
Effect of organic matter on the performance and N2O emission of a granular sludge anammox reactor
A continuously fed bubble column granular sludge anammox reactor was operated for 405 days to investigate the effect of organic matter on the reactor performance and N2O emission.
1,3,5-Trimethoxybenzene (TMB) as a new quencher for preserving redox-labile disinfection byproducts and for quantifying free chlorine and free bromine
1,3,5-Trimethoxybenzene can be used to quench residual chlorine and bromine without altering disinfection byproducts that are reactive toward traditional quenchers.
Effects of ortho- and polyphosphates on lead speciation in drinking water
Polyphosphates may increase lead solubility via complexation, but the risk is not well characterized. Size-exclusion chromatography with multi-element detection could help determine the prevalence of lead-polyphosphate complexes in drinking water.
Partial renewal of granular activated carbon biofilters for improved drinking water treatment
There is a trend of increasing natural organic matter (NOM) in raw drinking waters of Nordic countries due to climate change.
Copper current collectors reduce long-term fouling of air cathodes in microbial fuel cells
Long-term operation of wastewater-fed, microbial fuel cells (MFCs) with cathodes made of activated carbon and stainless steel (SS) current collectors can result in decreased performance due to cathode fouling.
Emerging investigators series: comparing the inherent reactivity of often-overlooked aqueous chlorinating and brominating agents toward salicylic acid
Rates and selectivity of salicylic acid halogenation can be influenced by highly electrophilic species such as Cl2, BrCl, and BrOCl.
Effect of elevated nitrate and sulfate concentrations on selenate removal by mesophilic anaerobic granular sludge bed reactors
The molar ratio of NO3− and SO42− to SeO42− is a key factor in SeO42− removal. A UASB reactor showed no inhibition of SeO42− at high NO3− and SO42− concentrations achieving 100% NO3−, 30% SO42− and 80% total Se removal efficiencies.
Wastewater from hydraulic fracturing in the UK: assessing the viability and cost of management
Mounds of salt recovered during treatment of wastewaters from hydraulic fracturing in the USA.
Methane-driven microbial fuel cells recover energy and mitigate dissolved methane emissions from anaerobic effluents
The effluents of mainstream anaerobic treatment processes such as anaerobic membrane bioreactors (AnMBRs) contain dissolved methane that represents a large fraction of the available energy (approximately 50% at 15 °C) and a significant greenhouse gas (GHG) emission if released to the atmosphere.
