Addition of conductive particles to improve the performance of activated carbon air-cathodes in microbial fuel cells
Inexpensive carbon black combined with heat-treatment produced the most effective activated carbon catalyst for improving microbial fuel cell cathode performance.
Influence of the sublayer structure of thin-film composite reverse osmosis membranes on the overall water flux
The support layer of RO membranes can significantly affect the permeability depending on its sublayer structure.
Elimination of transforming activity and gene degradation during UV and UV/H2O2 treatment of plasmid-encoded antibiotic resistance genes
This study determined deactivation of transforming activity of an ARG and the ARG degradation during UV and UV/H2O2 treatment of plasmid pUC19 containing an ampicillin resistance gene.

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.
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.
On the optimal design of forward osmosis desalination systems with NH3–CO2–H2O solutions
The optimal working pressure and composition of the draw solution is identified. The forward osmosis process is compared with reverse osmosis and thermal desalination in terms of specific work, membrane area, and second law efficiency.
Tailored water treatment using enhanced primary clarification for nutrient recovery and production of water for turfgrass irrigation
Enhanced primary clarification coupled with hypoaerobic biological treatment can produce fertigation water having targeted nitrogen and phosphorus concentrations without substantial changes to biological treatment and without increasing energy requirements.
Activity of methanogenic biomass after heat and freeze drying in air
This study successfully demonstrated that methanogenic communities can retain activity after freeze and heat drying in air.
Formation of bioactive transformation products during glucocorticoid chlorination
Glucocorticoid (GC) release into the environment has led to widespread detection of glucocorticoid receptor (GR) activity in water resources that has been shown to persist throughout conventional and some advanced wastewater treatment processes.
Demonstration of membrane distillation on textile waste water: assessment of long term performance, membrane cleaning and waste heat integration
A three month membrane distillation trial demonstrated innovative pretreatments, cleaning and waste heat integration as an inland textile industry wastewater solution.
Benzotriazole (BT) and BT plant metabolites in crops irrigated with recycled water
Novel benzotriazole plant metabolites were quantified for the first time in crops irrigated with recycled water, demonstrating an exposure route.
