Multi-resistance of human enterovirus to UV-C disinfection and mutagenic nucleoside analogs

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Qingxia Zhong

Disinfection is an important strategy to control the environmental transmission of human viruses. Specifically, UV254 is increasingly used to disinfect from clinical items or surfaces to drinking water. RNA virus populations have high mutation rates and la ...

Micropollutant degradation, bacterial inactivation and regrowth risk in wastewater effluents: Influence of the secondary (pre)treatment on the efficiency of Advanced Oxidation Processes

César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Stefanos Giannakis, Anoys Magnet

In this work, disinfection by 5 Advanced Oxidation Processes was preceded by 3 different secondary treatment systems present in the wastewater treatment plant of Vidy, Lausanne (Switzerland). 5 AOPs after two biological treatment methods (conventional acti ...

Accelerated bacterial reduction on Ag–TaN compared with Ag–ZrN and Ag–TiN surfaces

César Pulgarin, Juan Kiwi, Sami Rtimi, Oualid Baghriche

Ag–TaN sputtered on polyester (PES) accelerated >6 times the bacterial inactivation kinetics compared to TaN–PES under actinic light irradiation. Direct current pulsed magnetron sputtering (DCP) was used to sputter Ag–TaN–PES and TaN–PES. Complete bacteria ...

Environmental considerations on solar disinfection of wastewater and the subsequent bacterial (re)growth

César Pulgarin, Stefanos Giannakis

In this work, solar disinfection of wastewater was studied, focusing on the effect of selected environmental variables, namely light intensity, continuous/intermittent light delivery, and post-irradiation storage as well as dilution in lake water. These va ...

Evolution and characterization of MS2 bacteriophage and echovirus 11 Resistance to disinfection by CLO2

Tamar Kohn, Anna Carratala Ripolles, Qingxia Zhong

In this study, we investigate if frequent exposure to disinfectants promotes the emergence of virus resistance to disinfectants. We found that repeated passages causes viruses gain increasing resistance toward ClO2. However, the role of ClO2 is not clear i ...

Iron oxides semiconductors are efficients for solar water disinfection: A comparison with photo-Fenton processes at neutral pH

César Pulgarin, Andrzej Sienkiewicz, Michaël Bensimon, Cristina del Socorro Lonfat

The photocatalytic activities of four different commercially available iron (hydr)oxides semiconductors, i.e. hematite (alpha-Fe2O3), goethite (alpha-FeOOH), wustite (FeO) and magnetite (Fe3O4), were evaluated for bacteria inactivation at neutral pH in the ...

A conceptual model and experimental framework to determine the contributions of direct and indirect photoreactions to the solar disinfection of MS2, phiX174 and adenovirus

Tamar Kohn, Michael Jon Mattle

Sunlight inactivates waterborne viruses via direct (absorption of sunlight by the virus) and indirect processes (adsorption of sunlight by external chromophores, which subsequently generate reactive species) processes. While the mechanisms underlying these ...

Solar disinfection modeling and post-irradiation response of Escherichia coil in wastewater

César Pulgarin, Stefanos Giannakis

In this work, an intensive assessment of solar disinfection of secondary wastewater was elaborated in controlled laboratory conditions. Batch tests of Escherichia coil-spiked synthetic secondary effluent, at nine different constant intensity levels, were f ...
