The "Aerobic Granular Sludge" (AGS) technology for wastewater treatment is basedon dense microbial biofilm in the form of granular aggregates that have an excellentsettling property allowing high biomass concentrations in bioreactors. This promisingbiologi ...
EPFL2023Periodate activation with copper oxide nanomaterials for the degradation of ciprofloxacin- A new insight into the efficiency and mechanisms
In this study, CuO was synthesized using a facile precipitation method and was characterized using various techniques for the efficient activation of periodate (PI). Compared to systems consisting of PI alone (0.5 mM) and CuO alone (0.5 g/L), the CuO (0.5 ...
ELSEVIER SCI LTD2023Effect of wastewater treatment and environmental exposure on an enterovirus population
Odile Marie Clotilde Hervás de Nalda-Larivé
The presence of viruses in recreational water can present a risk for human health and wastewater effluent is a source of virus in the environment. Their persistence in the environment influences their probability to find a new host. Studies have shown that ...
EPFL2022Wastewater microorganisms impact microbial diversity and important ecological functions of stream periphyton
Effluents of wastewater treatment plants can impact microbial communities in the receiving streams. However, little is known about the role of microorganisms in wastewater as opposed to other wastewater constituents, such as nutrients and micropollutants. ...
Pergamon-Elsevier Science Ltd2022Effect of cetyltrimethylammonium chloride on various Escherichia coli strains and their inactivation kinetics by ozone and monochloramine
Urs von Gunten, Florian Frédéric Vincent Breider, Margaux Océane Voumard
Cethyltrimethylammonium chloride (CTMA) is one of the most used quaternary ammonium compounds (QACs) in consumer products. CTMA and other QACs are only partially eliminated in municipal wastewater treatment and they can interact with bacteria in biological ...
2022The capture technology matters: Composition of municipal wastewater solids drives complexity of microbial community structure and volatile fatty acid profile during anaerobic fermentation
Pierre Rossi, Arnaud Michel Gelb
The production of volatile fatty acids (VFAs) represents a relevant option to valorize municipal wastewater (MWW). In this context, different capture technologies can be used to recover organic carbon from wastewater in form of solids, while pre-treatment ...
2022Impact of wastewater on the microbial diversity of periphyton and its tolerance to micropollutants in an engineered flow-through channel system
Wastewater treatment plants (WWTPs) play an important role in retaining organic matter and nutrients but to a lesser extent micropollutants. Therefore, treated wastewater is recognized as a major source of multiple stressors, including complex mixtures of ...
