Fueling a SOFC with agricultural waste derived biogas - Analysing the Swiss case -

The use of fuel cells for valorising agricultural and food-waste-derived biogas in Switzerland is studied. The Swiss agricultural case is characterised by farms with small numbers of animals (20 cows) and high feed-in tariffs for biogas derived electricity ...

Ammonia as an in-situ sanitizer: influence of virus genome type on inactivation

Tamar Kohn, Loïc Decrey, Shinobu Kazama

Treatment of human excreta and animal manure (HEAM) is key in controlling the spread of persistent enteric pathogens such as viruses. The extent of virus inactivation during HEAM storage and treatment appeared to vary with virus genome type, though the rea ...

Organic Contaminant Abatement in Reclaimed Water by UV/H2O2 and a Combined Process Consisting of O-3/H2O2 Followed by UV/H2O2: Prediction of Abatement Efficiency, Energy Consumption, and Byproduct Formation

Urs von Gunten, Minju Lee, Yun Ho Lee, Silvio Canonica

UV/H2O2 processes can be applied to improve the quality of effluents from municipal wastewater treatment plants by attenuating trace organic contaminants (micropollutants). This study presents a kinetic model based on UV photolysis parameters, including UV ...

Micropollutant degradation, bacterial inactivation and regrowth risk in wastewater effluents: Influence of the secondary (pre)treatment on the efficiency of Advanced Oxidation Processes

César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Stefanos Giannakis, Anoys Magnet

In this work, disinfection by 5 Advanced Oxidation Processes was preceded by 3 different secondary treatment systems present in the wastewater treatment plant of Vidy, Lausanne (Switzerland). 5 AOPs after two biological treatment methods (conventional acti ...

Virus inactivation mechanisms in human urine and fecal sludge

Loïc Decrey

Water, sanitation and hygiene interventions are among the most significant health interventions addressing the worldwide burden of diarrheal disease and environmental enteropathy. Sanitizing human excreta and animal manure (HEAM) is a critical step in redu ...

Sanitation of virus in human excreta and animal manure: a focus on mechanisms underlying inactivation heterogeneity

Tamar Kohn, Loïc Decrey, Shinobu Kazama, Kai Udert

Water, sanitation and hygiene interventions are among the most significant health interventions addressing the worldwide burden of diarrheal disease and environmental enteropathy. It was recently established that despite an increase in global toilet covera ...

Ammonia as an in-situ sanitizer: inactivation kinetics and mechanisms of the ssRNA virus MS2 by NH3

Tamar Kohn, Loïc Decrey, Shinobu Kazama, Kai Udert

Sanitizing human and animal waste (e.g., urine, fecal sludge or grey water) is a critical step in reducing the spread of disease and ensuring microbially safe reuse of waste materials. Viruses are particularly persistent pathogens and can be transmitted th ...

Technologies for the treatment of source-separated urine in the eThekwini Municipality

Tamar Kohn, Linda Strande, Kai Udert, Bastian Etter

In recent years, a large number of urine-diverting dehydration toilets (UDDTs) have been installed in eThekwini to ensure access to adequate sanitation. The initial purpose of these toilets was to facilitate faeces drying, while the urine was diverted into ...

Pathogens and pharmaceuticals in source-separated urine in eThekwini, South Africa

Tamar Kohn, Linda Strande, Kai Udert, Christa McArdell

In eThekwini, South Africa, the production of agricultural fertilizers from human urine collected from urine-diverting dry toilets is being evaluated at a municipality scale as a way to help finance a decentralized, dry sanitation system. The present study ...
