AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The effect of different chemical parameters on photocatalytic inactivation of E. coli K12 is discussed. Illumination was produced by a solar lamp and suspended TiO2 P-25 Degussa was used as catalyst. Modifications of initial pH between 4.0 and 9.0 do not a ...
Evaluation of solar treatment in the absence and presence of TiO2 has been made to assess its effectiveness in reducing bacterial load with respect to drinking water standards. Field experiments under direct solar radiation were carried out using a compoun ...
Oxidative processes are often harnessed as tools for pathogen disinfection. Although the pathways responsible for bacterial inactivation with various biocides are fairly well understood, virus inactivation mechanisms are often contradictory or equivocal. I ...
The aim of this study was to determine the difference in disinfection between aggregated and dispersed virus. Bacteriophage MS2 was chosen as a surrogate for enteric virus. The first part of this project consisted of characterizing the aggregation of MS2 a ...
Adsorption onto iron oxides can enhance the removal of waterborne viruses in constructed wetlands and soils. If reversible adsorption is not coupled with inactivation, however, infective viruses may be released when changes in solution conditions cause des ...
The effect of Fe2+, Fe3+, H2O2 and the photo-Fenton system (Fe2+or3+/H2O2/hv) on solar water disinfection (SODIS) at low temperature and at near neutral pH are discussed in detail. We focus on Escherichia coil K12 suspended in either MilliQ water, water co ...
