Prediction of transformation products during ozonation of micropollutant-containing waters

Ozonation, which is widely used for drinking water disinfection, has recently been applied to mitigate potentially harmful effects of micropollutants (e.g., pharmaceuticals, personal care products, pesticides, etc.) present in municipal wastewater effluent ...

Super-fine powdered activated carbon (SPAC) for efficient removal of micropollutants from wastewater treatment plant effluent

Tamar Kohn, Florence Bonvin, Livia Jost, Léa Cécile Randin

In an effort to mitigate the discharge of micropollutants to surface waters, adsorption of micropollutants onto powdered activated carbon (PAC) after conventional wastewater treatment has been identified as a promising technology for enhanced removal of ph ...

Advances in predicting organic contaminant abatement during ozonation of municipal wastewater effluent: reaction kinetics, transformation products, and changes of biological effects

Urs von Gunten, Yun Ho Lee

Ozonation of municipal wastewater effluent has been considered in recent years as an enhanced wastewater treatment technology to abate trace organic contaminants (micropollutants). The efficiency of ozonation for micropollutant abatement depends on (1) the ...

Emerging investigators series: prediction of trace organic contaminant abatement with UV/H2O2: development and validation of semi-empirical models for municipal wastewater effluents

Urs von Gunten, Minju Lee, Yun Ho Lee

Recent evaluations of potable reuse treatment trains suggest that the use of UV and UV/H2O2 may become increasingly common, particularly in systems employing ozone and/or biofiltration. This study provides a summary of photolysis rate constants and (OH)-O- ...

Synthesis of non-isothermal water networks including process hot and cold streams

François Maréchal, Maziar Kermani

The synthesis problems of non‒isothermal water networks have received considerable attention throughout academia and industry over the last two decades because of the importance of simultaneously minimising water and energy consumption [1]. Most papers hav ...

Use of light-supported oxidation processes towards microbiological and chemical contaminants elimination in hospital wastewaters

Stefanos Giannakis

Hospital wastewaters have been long identified as carriers of chemical and microbiological pollutants. Their amounts and risk levels have initiated numerous works on changing the existing practices of co-treatment with municipal wastewaters and safe dispos ...

Enhancing the photo-Fenton treatment of contaminated water by use of ultrasound and iron-complexing agents

Stefanos Papoutsakis

The photo-Fenton process is a promising emerging technology for the treatment of contaminated water streams. It is based on the generation of reactive oxygen species that are capable of destroying recalcitrant contaminants otherwise unaffected by conventio ...

Evolution of microbial communities and nutrient removal performances in aerobic granular sludge sequencing batch reactor during change of substrate

Christof Holliger, Julien Maillard, Aline Sondra Adler, Valérie Berclaz, Marie Christelle Horisberger

• Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conventional activated sludge system. As AGS has enhanced settling abilities and provides different redox conditions across the granules at the same time, the processes ...

Temperature-dependent change of light dose effects on E. coli inactivation during simulated solar treatment of secondary effluent

César Pulgarin, Stefanos Giannakis

In 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 process was performed (time, t ...
