D35-TiO2 nano-crystalline film as a high performance visible-light photocatalyst towards the degradation of bis-phenol A

Dye-sensitized photocatalytic suspension system for wastewater treatment is still limited in practice due to particle aggregation, fast charge carrier recombination, poor stability and recycling issue. In this study, we combine TiO2 nano-crystalline film w ...

Proxies to monitor the inactivation of viruses by ozone in surface water and wastewater effluent

Urs von Gunten, Tamar Kohn, Camille Wolf, Annalisa Pavese

Ozone treatment is an effective barrier against viral pathogens, therefore it is an integral part of many water and wastewater treatment trains. However, the efficacy of ozone treatment remains difficult to monitor, due to the lack of methods to track viru ...

Susceptibility of Enterovirus B strains to disinfectants and heat

Simon Meister

The susceptibility of waterborne viruses to different inactivating treatments is acknowledged to vary between viruses and even between closely related strains, yet the extent of this variation, or the underlying mechanisms, are not known. Here, different e ...

The effect of different organic substrates on the microbial communities of aerobic granular wastewater treatment sludge

Aline Sondra Adler

Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conven- tional activated sludge system, allowing space and energy savings. This process is particularly suited for biological phosphorus removal, avoiding use of coagulant ...

A combined hydrothermal gasification - solid oxide fuel cell system for sustainable production of algal biomass and energy

François Maréchal, Jan Van Herle, Christian Ludwig, Shivom Sharma, Hossein Madi

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system oper ...

Organic substrate diffusibility governs microbial community composition, nutrient removal performance and kinetics of granulation of aerobic granular sludge

Christof Holliger, Eva Reynaert

Basic understanding of formation of aerobic granular sludge (AGS) has mainly been derived from labscale systems with simple influents containing only highly diffusible volatile fatty acids (VFA) as organic substrate. This study compares start-up of AGS sys ...

Influence of Wastewater Composition on the Microbial Communities of Aerobic Granular sludge

Christof Holliger, Julien Maillard, Aline Sondra Adler, Valérie Berclaz, Marie Christelle Horisberger, Eva Reynaert

Aerobic granular sludge (AGS) is an emerging technology offering an alternative wastewater treatment with a reduced footprint compared to conventional activated sludge systems. Basic understanding of AGS processes has mainly been obtained in laboratory-sca ...

Persistence of sewage-borne enteroviruses through chlorination treatment

Jade Brandani

Enteroviruses are a leading cause in a diversity of severe human diseases worldwide and the presence of these viruses in recreational water can present a risk for human health. Viruses' capacity to persist in the outside environment is limited but some vir ...

Inactivation of waterborne viruses by ozone: Kinetics and mechanisms

Camille Wolf

The growing world population, in conjunction with climate change, cases the global water de-mand to increase. It is, therefore, crucial to protect existing water resources from chemical pollution and contamination by pathogens. An increasingly popular stra ...

The utility of flow cytometry for potable reuse

Tamar Kohn, Krista Rule Wigginton, Brian Pecson

Protecting public health from pathogens is critical when treating wastewater to drinking water standards (i.e., planned water reuse). Viruses are a principal concern, yet real-time monitoring strategies do not currently measure virus removal through reuse ...
