AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
On-site sanitation technologies such as septic tanks are widely used in low- and middle-income countries. A comprehensive management of the accumulating faecal sludge (FS) is however missing in most contexts and uncontrolled disposal of FS results in serio ...
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 ...
As strategies in sustainability permeate modern engineering approaches, opportunities to re-engineer our water and sanitation systems in ways that simultaneously address human and ecological needs become apparent. Yet uncertainties remain regarding the hum ...
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 ...
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 ...
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 ...
Context Worldwide: FS production much larger than treated volumes In Vietnam: • Urban households required to own septic tanks • Combined onsite and centralized sanitation • FS emptying frequency up to 10 years or more Negligible FS volumes treated before d ...
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 ...
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 ...
This Master thesis comes within the framework of the PURR project (Partnership for Urban Resource Recovery), which is a collaboration between the Department of Water and Sanitation in Developing Countries (Sandec) at the Swiss Federal Institute of Aquatic ...
