The utility of flow cytometry for potable reuse

Tamar Kohn, Brian Pecson, Krista Rule Wigginton

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 ...

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

Ulf Anders Hagfeldt, Lin Yang, Xue Bai

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

Tamar Kohn, Camille Wolf, Urs von Gunten, 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 ...

Enhancing solar disinfection of water in PET bottles by optimized in-situ formation of iron oxide films. From heterogeneous to homogeneous action modes with H2O2 vs. O-2 - Part 2: Direct use of (natural) iron oxides

César Pulgarin, Sami Rtimi, Stefanos Giannakis, Sakine Shekoohiyan

Solar disinfection (SODIS) is a well-accepted intervention method, leading to an improvement in contaminated water sources. In this work, we attempted to further enhance the bacterial inactivation process during light exposure. By means of iron oxide addit ...

Pepper mild mottle virus as a water quality indicator

Jason Robert Torrey

Pepper mild mottle virus (PMMoV) was recently found to be the most abundant RNA virus in human feces, and is a plant virus belonging to the genus Tobamovirus in the family Virgoviridae. When in human feces, it is of dietary origin from peppers and their pr ...

Sunlight-mediated inactivation of health-relevant microorganisms in water: A review of mechanisms and modeling approaches

Tamar Kohn, Krista Rule Wigginton, Yang Liu

Health-relevant microorganisms present in natural surface waters and engineered treatment systems that are exposed to sunlight can be inactivated by a complex set of interacting mechanisms. The net impact of sunlight depends on the solar spectral irradianc ...

Nitrate formation during ozonation as a surrogate parameter for abatement of micropollutants and the N-nitrosodimethylamine (NDMA) formation potential

Florian Frédéric Vincent Breider, Urs von Gunten, Jun Ma, Yang Song

In this study, nitrate formation from ammonium and/or dissolved organic nitrogen (DON) was investigated as a novel surrogate parameter to evaluate the abatement of micropollutants during ozonation of synthetic waters containing natural organic matter (NOM) ...
