Health risks for sanitation service workers along a container-based urine collection system and resource recovery value chain

Tamar Kohn, Simon Schindelholz, Timothy R. Julian

Container-based sanitation (CBS) within a comprehensive service system value chain offers a low-cost sanitation option with potential for revenue generation, but may increase microbial health risks to sanitation service workers. This study assessed occupat ...

Thomson scattering measurements in the divertor region of the TCV Tokamak plasmas

Basil Duval, Ivo Furno, Patrick Blanchard, Joan Decker, Xavier Llobet, Yanis Andrebe, Pierre Lavanchy, Riccardo Agnello, Steve Couturier, Severino Antonioni, Blaise Marlétaz, Pierre-François Isoz

In order to better study conventional and alternative divertor configurations, the TCV Tokamak was recently upgraded. In-vessel graphite baffles were installed in the TCV chamber to delimit a separate divertor chamber from the core that required enhanced d ...

Mechanisms and modeling of pathogen fate in pilot scale nutrient recovery reactors

Loïc Decrey, Simon Schindelholz, Manfred Schoger, Ariane Schertenleib, Timothy R. Julian

Due to its high nutrient content, source-separated urine can be processed into marketable liquid or solid fertilizers. The Valorisation of Urine Nutrients in Africa (VUNA) project developed and tested pilot-scale nitrification/distillation and struvite (Mg ...

Reaction extents: A Divide-and-Conquer Approach for Kinetic Model Identification

Dominique Bonvin, Julien Léo Billeter

Obtaining reliable wastewater treatment process models is critical for the application of model-based design, operation, and automation. For example, Masic et al. (2014) explored the use of an observer designed for nonlinear processes to estimate nitrite i ...

Towards sustainable sanitation: Identifying and mitigating microbial health risks in the production of urine-derived fertilizers

Tamar Kohn, Simon Schindelholz, Timothy R. Julian

Sanitation systems that systematically recover and reuse waste can promote social enterprise, reduce discharge of harmful nutrients, pathogens and other contaminants to the environment, replace synthetic fertilizer sources, and increase access to sanitatio ...

Solar photo-Fenton and UV/H2O2 processes against the antidepressant Venlafaxine in urban wastewaters and human urine. Intermediates formation and biodegradability assessment

Hubert Girault, César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Stefanos Giannakis, Milica Jovic, Idriss Hendaoui

In this work, the use of Advanced Oxidation Processes (AOPs) against the degradation of an emerging contaminant has been subjected under systematic investigation. The optimization of treatment of the anti- depressant drug Venlafaxine (VFA) was performed, u ...

Quantifying microbial risks of field-scale struvite production from source-separated urine using first-person videography exposure assessment

Tamar Kohn, Ana Karina Pitol Garcia, Timothy R. Julian

This paper quantifies occupational exposures to pathogens in urine during urine collection and processing into fertilizer as well as attendant risks of infection from indirect pathogen exposure. We also detail the microlevel activity time series (MLATS) me ...

Hygiene considerations during the collection, storage and processing of source-separated urine into a marketable fertilizer

Tamar Kohn, Simon Schindelholz, Manfred Schoger

Laboratory and field studies along with inactivation data from the literature are used to model bacteria inactivation during urine storage and struvite production. The model is used to evaluate urine storage and struvite drying under the fluctuating temper ...
