Elucidating bacterial regrowth: effect of disinfection conditions in dark storage of solar treated secondary effluent
(2014-09-15)
Article
Open AccessIn 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 ... -
Environmental considerations on solar disinfection of wastewater and the subsequent bacterial (re)growth
(Royal Society of Chemistry, 2015-03-01)
Article
Open AccessIn 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 ... -
Impact of different light intermittence regimes on bacteria during simulated solar treatment of secondary effluent: implications of the inserted dark periods
(2013-12)
Article
Open AccessIn 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 ... -
Light wavelength-dependent E. coli survival changes after simulated solar disinfection of secondary effluent
(2015-12-01)
Article
Open AccessIn this study, the photoreactivation and the modification of dark repair of E. coli in a simulated secondary effluent were investigated after initial irradiation in different conditions. The simulated solar exposure of the ... -
Monitoring the post-irradiation E-coli survival patterns in environmental water matrices: implications in handling solar disinfected wastewater
(2014-10-01)
Article
Open AccessIn this study, simulated solar disinfection of secondary effluent was followed by dark storage at different temperatures or different receiving water matrices. Escherichia coil illumination was followed by 3-day monitoring ... -
Solar disinfection modeling and post-irradiation response of Escherichia coli in wastewater
(2015-12-01)
Article
Open AccessIn this work, an intensive assessment of solar disinfection of secondary wastewater was elaborated in controlled laboratory conditions. Batch tests of Escherichia coli-spiked synthetic secondary effluent, at nine different ... -
Solar disinfection of secondary effluent and the subsequent bacterial regrowth : considerations, limitations and environmental perspectives
(Universitat Politècnica de Catalunya, 2014-10-29)
Doctoral thesis
Open AccessThe present Thesis deals with the solar disinfection of synthetic secondary effluent under laboratory controlled conditions, focusing on the post-irradiation bacterial regrowth. The influence of various internal and external ... -
Temperature-dependent change of light dose effects on E. coli inactivation during simulated solar treatment of secondary effluent
(2015-04-14)
Article
Open AccessIn this study, simulation of solar disinfection of secondary effluents was performed, to assess the dose effects, as instructed by the reciprocity law. A full factorial experimental design on the operational parameters of ... -
The antagonistic and synergistic effects of temperature during solar disinfection of synthetic secondary effluent
(2014-04-15)
Article
Open AccessA 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 ... -
Ultrasound enhancement of near-neutral photo-Fenton for effective E. coli inactivation in wastewater
(2015-01-01)
Article
Open AccessIn this study, we attempt for the first time to couple sonication and photo-Fenton for bacterial inactivation of secondary treated effluent. Synthetic wastewater was subjected to sequential high-frequency/low power sonication, ...
