Effect of Fe(II)/Fe(III) species, pH, irradiance and bacterial presence on viral inactivation in wastewater by the photo-Fenton process: Kinetic modeling and mechanistic interpretation

César Pulgarin, Michaël Bensimon, Anna Carratala Ripolles, Sami Rtimi, Stefanos Giannakis, Siting Liu

Advanced Oxidation Processes and in particular photo-Fenton, represent promising strategies of pathogen inactivation in wastewater effluents. Nevertheless, its full potential is not yet unlocked, as the efficacy of photo-Fenton against viruses has not been ...

Cross-resistance of UV- or chlorine dioxide-resistant echovirus 11 to other disinfectants

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

The emergence of waterborne viruses with resistance to disinfection has been demonstrated in the laboratory and in the environment. Yet, the implications of such resistance for virus control remain obscure. In this study we investigate if viruses with resi ...

Genetic, structural and phenotypic properties of MS2 coliphage with resistance to ClO2 disinfection

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Sergey Nazarov, Petr Leiman, Qingxia Zhong, Ricardo Cesar Guerrero Ferreira, Laura Piccinini

Common water disinfectants like chlorine have been reported to select for resistant viruses, yet little attention has been devoted to characterizing disinfection resistance. Here, we investigated the resistance of MS2 coliphage to inactivation by chlorine ...

Solar disinfection (SODIS) of viruses in PET bottles

Tamar Kohn, Anna Carratala Ripolles, Michael Jon Mattle, Alex Dionisio Calado

Solar disinfection of drinking water in PET bottles (SODIS) is a simple point-of-use technique efficient for the inactivation of many bacterial pathogens. In contrast, the efficiency of SODIS toward viruses is not well known. In this work, we studied the i ...

Principal parameters affecting virus inactivation by the solar photo-Fenton process at neutral pH and mu M concentrations of H2O2 and Fe2+/(3+)

César Pulgarin, Anna Carratala Ripolles

The inactivation of the coliphage MS2 (a human virus indicator) by solar photo-Fenton at near neutral pH in carbonate buffer solution matrix was evaluated. The effects of reactant concentration (H2O2, Fe2+, Fe3+) and solar irradiance on the photo-Fenton pr ...

UVC inactivation of dsDNA and ssRNA viruses in water: UV fluences and a qPCR-based approach to evaluate decay on viral infectivity

Tamar Kohn, Anna Carratala Ripolles

Disinfection by low-pressure monochromatic ultraviolet (UVC) radiation (253.7 nm) became an important technique to sanitize drinking water and also wastewater in tertiary treatments. In order to prevent the transmission of waterborne viral diseases, the an ...
