Visible light plays a significant role during bacterial inactivation by the photo-fenton process, even at sub-critical light intensities

César Pulgarin, Stefanos Giannakis, Rosa Mosteo, David Muzard, Angelica Varon Lopez

The aim of this research is to clarify the contribution of sunlight wavelengths, irradiance and Fe2+/H2O2 during bacterial disinfection by the photo-Fenton process in clear surface waters. We considered different solar spectrum distributions (visible, UVA- ...

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

Tamar Kohn, Yang Liu, Krista Rule Wigginton

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 ...

Experimental adaptation of human echovirus 11 to ultraviolet radiation leads to tolerance to disinfection and resistance to ribavirin

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Jeffrey David Jensen, Qingxia Zhong, Hyunjin Shim

Ultraviolet light in the UVC range is a commonly used disinfectant to control viruses in clinical settings and water treatment. Here, we employed an experimental evolution approach to investigate the adaptation of human echovirus 11 to disinfection by UVC, ...

Light wavelength-dependent E. coli survival changes after simulated solar disinfection of secondary effluent

César Pulgarin, Sami Rtimi, Stefanos Giannakis

In this study, the photoreactivation and the modification of dark repair of E. coli in a simulated secondary effluent were investigated after initial irradiation under different conditions. The simulated solar exposure of the secondary wastewater was follo ...

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 ...

Mechanisms of Human Adenovirus Inactivation by Sunlight and UVC Light as Examined by Quantitative PCR and Quantitative Proteomics

Tamar Kohn, Romain Hamelin, Florence Armand, Franziska Sara Bosshard

Human adenoviruses (HAdV) are important pathogens in both industrialized and developing nations. HAdV has been shown to be relatively resistant to monochromatic UVC. Polychromatic UVC, in contrast, is a more effective means of disinfection, presumably due ...

Elimination of Micropollutants during Post-Treatment of Hospital Wastewater with Powdered Activated Carbon, Ozone, and UV

Urs von Gunten, Hansruedi Siegrist

A pilot-scale hospital wastewater treatment plant consisting of a primary clarifier, membrane bioreactor, and five post-treatment technologies including ozone (O-3), O-3/H2O2, powdered activated carbon (PAC), and low pressure UV light with and without TiO2 ...

A ratiometric fluorescence sensor for caffeine

Kay Severin, Albert Ruggi, Nicolas Luisier, Nicolas David Gaeng, Laurane Favre

The dye disodium 3,4:3’,4’-bibenzo[b]thiophene-2,2’-disulfonate can be used as molecular probe for the fluorimetric detection of caffeine in aqueous solution. The fluorescence response is attributed to non-covalent interactions of caffeine with the dye in ...
