The solvothermal synthesis of a 3D rod-like Fe–Al bimetallic metal–organic-framework for efficient fluoride adsorption and photodegradation of water-soluble carcinogenic dyes
Thermally stable, 3D rod-like, nanosized, pH-stable Fe–Al metal–organic-framework with terephthalic acid as a linker with a surface area 120.255 m2 g−1 was synthesized solvothermally for fluoride adsorption and the photodegradation of rhodamine B/methylene blue (pH 2–11).
A flexible copper sulfide composite membrane with tunable plasmonic resonance absorption for near-infrared light-driven seawater desalination
A flexible CuS/Matrimid composite membrane with tunable near-infrared absorption is constructed. The composite membrane exhibits good near-infrared light-driven photothermal vapor evaporation and seawater desalination effects.
A case study on tap water quality in large buildings recommissioned after extended closure due to the COVID-19 pandemic
Extensive building closures due to the unprecedented COVID-19 pandemic resulted in long-term water stagnation within the plumbing of large buildings.
Bi2O3/nylon multilayered nanocomposite membrane for the photocatalytic inactivation of waterborne pathogens and degradation of mixed organic pollutants
Bi2O3/nylon multilayered nanocomposite membrane was fabricated by electrospinning and effectively used to degrade organic dye pollutants and pathogens through ROS produced by photocatalysis.
Biodegradation mechanisms and functional microbiology in conventional septic tanks: a systematic review and meta-analysis
Knowledge gaps exist pertaining to the interaction between anaerobic conditions, microbiology and activity that characterize biodegradation mechanisms in septic tanks.
Hierarchically aligned nano silver/chitosan–PVA hydrogel for point-of-use water disinfection: contact-active mechanism revealed
Mechanically robust Ag/CS–PVA hydrogel displayed 100% disinfection efficacy against biomedical/natural contaminants through contact-active mechanism with ∼74 ppb Ag release.
Sewer biofilm microbiome and antibiotic resistance genes as function of pipe material, source of microbes, and disinfection: field and laboratory studies
Wastewater systems are recognized pathways for the spread of antibiotic resistant bacteria, but relatively little is known about the microbial ecology of the sewer environment.
Nano-sized iron oxides supported on polyester textile to remove fluoroquinolones in hospital wastewater
Nano-sized iron oxides supported on textile is successfully used for PMS activation and thus flumequine and ciprofloxacin removal in hospital wastewater under visible light.
Safe resource recovery from faecal sludge: evidence from an innovative treatment system in rural Tanzania
A novel treatment system for pit latrine faecal sludge; solar-dried sludge with captured leachate heat-treated in agriculture using waste-fired rocket stove.
Field testing of an onsite sanitation system on apartment building blackwater using biological treatment and electrochemical disinfection
Demonstration of an electrochemical toilet wastewater treatment and disinfection technology at the scale of an apartment building and translation of the system into a commercial product.
Electrochemical simultaneous denitrification and removal of phosphorus from the effluent of a municipal wastewater treatment plant using cheap metal electrodes
Nitrate and phosphate in the effluent of a municipal wastewater treatment plant (MWTP) were electrochemically removed with cheap metal (aluminum and iron) electrodes.
Vertically-aligned growth of CuAl-layered double oxides on reduced graphene oxide for hybrid capacitive deionization with superior performance
Designing vertically-aligned CuAl-layered double oxide grown on reduced graphene oxide for capacitive desalination with high capacity and long cycling life.
Field testing of low-cost titania-based photocatalysts for enhanced solar disinfection (SODIS) in rural India
We report the efficacy of titania-based photocatalysts for use as a simple and effective method of disinfecting drinking water in villages in West Bengal, demonstrating the viability of this technique to enhance solar disinfection in rural areas.
