Development of a new simple fluorometric method for total N-nitrosamines analysis in water
N-nitrosamines are known as carcinogenic compounds and arouse today more and more attention as micropollutants and disinfection by-products. Indeed, they were newly found in several drinking waters, wastewaters and greywaters. It was proven that they can f ...
2017Study of a photocatalytic process for removal of antibiotics from wastewater in a falling film photoreactor: Scavenger study and process intensification feasibility
This study focused on the removal of antibiotic by coupling of heterogeneous photocatalysis with ozonation and hydrogen peroxide. The main objective was to intensify the efficiency of photocatalytic activity for better and faster antibiotic elimination/min ...
Elsevier2017MEMBRO3X, a Novel Combination of a Membrane Contactor with Advanced Oxidation (O-3/H2O2) for Simultaneous Micropollutant Abatement and Bromate Minimization
Ozonation is a water treatment process for disinfection and/or micropollutant abatement. However, ozonation of bromide-containing water leads to bromate (BrO3-) formation, a potential human carcinogen. A solution for mitigating BrO3- formation during abate ...
Amer Chemical Soc2017Remarkable enhancement of bacterial inactivation in wastewater through promotion of solar photo-Fenton at near-neutral pH by natural organic acids
César Pulgarin, Stefanos Giannakis, Paola Villegas Guzman
In this work, the near-neutral photo-Fenton process, as a means of wastewater disinfection, was enhanced by the addition of Organic Acids (OAs), namely citric, ascorbic, tartaric and caffeic acid. The addition of OAs exhibited significant bacterial inactiv ...
Elsevier2017Synchronic coupling of Cu2O(p)/CuO(n) semiconductors leading to Norfloxacin degradation under visible light: Kinetics, mechanism and film surface properties
César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Gcina Mamba
The study presents the first evidence for Norfoxacin photodegradation by uniform, adhesive and robust CuOx-polystyrene (CuOx-PES) films under visible light. Repetitive Norfloxacin degradation was attained on CuOx-PES films activated by visible light. The s ...
Elsevier2017Grafted semiconductors on PE-films leading to bacterial inactivation: Synthesis, characterization and mechanism
César Pulgarin, Juan Kiwi, Sami Rtimi
This study reports the colloidal preparation FeOx, TiO2 and FeOx-TiO2 grafted on polyethylene (PE) films leading to bacterial inactivation. A fast bacterial inactivation was attained by the FeOx-TiO2 compared to the FeOx-PE film due to the interfacial char ...
Elsevier2017A green solar photo-Fenton process for the elimination of bacteria and micropollutants in municipal wastewater treatment using mineral iron and natural organic acids
César Pulgarin, Michaël Bensimon, Dominique Grandjean, Luiz Felippe De Alencastro, Sami Rtimi, Stefanos Giannakis, Paola Villegas Guzman
In this investigation, a new, green photo-Fenton process for wastewater treatment is proposed, involving the use of a natural iron source and natural additives, deriving from wastes, acting as iron chelators. The use of mineral iron as precursor in the pho ...
Elsevier Science Bv2017Modeling and treatment optimization of pharmaceutically active compounds by the photo-Fenton process: The case of the antidepressant Venlafaxine
César Pulgarin, Sami Rtimi, Stefanos Giannakis, Idriss Hendaoui
In this study, the anti-depressant Venlafaxine, a new emerging contaminant of interest for the Swiss legislation, was subjected to systematic degradation. In order to develop an efficient framework for the treatment of emerging contaminants at industrial s ...
Elsevier Sci Ltd2017Transformation of Contaminant Candidate List (CCL3) compounds during ozonation and advanced oxidation processes in drinking water: Assessment of biological effects
Urs von Gunten, Kristin Schirmer, Silvio Canonica
The removal of emerging contaminants during water treatment is a current issue and various technologies are being explored. These include UV- and ozone-based advanced oxidation processes (AOPs). In this study, AOPs were explored for their degradation capab ...
Pergamon-Elsevier Science Ltd2016Enhancement of the Fenton and photo-Fenton processes by components found in wastewater from the industrial processing of natural products: The possibilities of cork boiling wastewater reuse
César Pulgarin, Stefanos Papoutsakis
Some wastewaters from the industrial processing of natural products, such as cork boiling wastewater (CBW), have been known to contain high quantities of polyphenolic compounds that are capable of forming complexes with ferric and ferrous iron and even con ...
