There is an urgent need to develop comprehensive and sustainable sanitation systems in developing countries, including faecal sludge (FS) treatment technologies that help reduce environmental and human health risks. Anaerobic digestion (AD) is widely used ...
Following the empirical evidence of a clear correlation between rainfall events and cholera resurgence that was observed in particular during the recent outbreak in Haiti, a spatially explicit model of epidemic cholera is re-examined. Specifically, we test ...
The present Thesis deals with understanding, measuring and modelling epidemic cholera. The relevance of the endeavour stems from the fact that mathematical epidemiology, properly guided by model-guided field validation, is a reliable and powerful tool to m ...
Urine source separation (NoMix technology) is a promising innovation in wastewater management. To improve and further develop NoMix technology, it has been implemented in four Swiss households and at our research institute (Eawag). We conducted measurement ...
Faecal sludge (FS) accumulates in onsite sanitation technologies, which play a prevailing role in low- and middle-income countries. However, FS management is generally lacking. FS is usually directly discharged in the environment despite its high organic l ...
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 ...
Human urine has the potential to be a sustainable, locally and continuously available source of nutrients for agriculture. Phosphate can be efficiently recovered from human urine in the form of the mineral struvite (MgNH4PO4•6H2O). However, struvite format ...
