Virus removal and inactivation is still a major challenge for water treatment facilities in both industrialised nations and developing countries. This may seem surprising as chlorine disinfection started to spread broadly over a century ago. However, many ...
A 4-factor, multilevel, full factorial design of 240 experiments was performed in order to investigate the effect of temperature on the inactivation efficiency of spiked Escherichia coli in simulated solar disinfection of a synthetic secondary effluent. Th ...
Despite their potential carcinogenicity and probable formation during water disinfection processes, little is known about the occurrence of other nitro(so) compounds than a few specific N-nitroso compounds such as N-nitrosodimethylamine (NDMA). An analytic ...
Disinfection of surface water containing dissolved iron (0.3 mg L-1) at natural neutral pH (similar to 7.5) was carried out via solar disinfection (SODIS) treatment in PET bottles with H2O2 (10 mg L-1). Wild coliforms and Salmonella sp. were monitored for ...
My PhD thesis aims to obtain the structure of several bacteriophages, including so-called “jumbo” phages, using the electron cryo-microscopy (cryo-EM) and to study the structural transformation of these viruses as they attach and infect the host cell. We a ...
In this study, the effect of light intermittence on solar disinfection of secondary treated wastewater was investigated. Synthetic secondary effluent was spiked with Escherichia coli and submitted to 3 different light intermittence regimes by circulating t ...
The inactivation of total coliforms/E. coli (10(4) CFU/mL) and Salmonella spp. (10(5) CFU/mL) in well water naturally containing dissolved (Fe2+/3+) and solid iron forms (e.g. iron oxides) was carried out by photo Fenton treatment (Fe-2+,Fe-3+/H2O2/hv). In ...
In this study, we systematically investigate solar disinfection of synthetic secondary wastewater, with the effort to decrypt the effects disinfection conditions have on post-irradiation bacterial regrowth in the dark. A full factorial design of 240 experi ...
Background, aim and scope After the discovery of chloroform in drinking water, an extensive amount of work has been dedicated to the factors influencing the formation of halogenated disinfections by-products (DBPs). The disinfection practice can vary signi ...
Bacteriophages with contractile tails epitomize the concepts of "virus" and "phage" for many because the tails of these phages undergo a large conformational change - resembling the action of a syringe - upon the attachment to the host cell. The contractil ...
