Water and sanitation hub in Mali. Reasons for an architecture seminar

Riccardo Vannucci

What is the goal of a five-day seminar for the (architectural) design of a ‘water and sanitation hub’ in Mali? What does one want to achieve, or rather, what is the seminar meant to ‘disseminate’? To begin with, what is a ‘water and sanitation hub’? It is ...

Modelling quantities and qualities (Q&Q) of faecal sludge in Hanoi, Vietnam and Kampala, Uganda for improved management solutions

Magalie Diane Bassan, Linda Strande, Amédé Ferré

The importance of faecal sludge management is gaining recognition. However, methods are still lacking to reasonably estimate the quantities and qualities (Q&Q) that need to be managed, which makes the planning for and implementing of management solutions q ...

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 ...

Safely Managed Hygiene: A Risk-Based Assessment of Handwashing Water Quality

Matthew Eric Verbyla, Timothy R. Julian

Sustainable Development Goal (SDG) Indicator 6.2.1 requires household handwashing facilities to have soap and water, but there are no guidelines for handwashing water quality. In contrast, drinking water quality guidelines are defined: water must be "free ...

Statistical comparison of the performance of data-based models for sewer condition modeling

José Pedro Gamito de Saldanha Calado Matos

The present article proposes a methodology to consider the uncertainty intrinsic to data-based models when comparing their performance. The goal is to provide a quantification of the variability of this type of models due to the random nature of the calibr ...

A combined hydrothermal gasification - solid oxide fuel cell system for sustainable production of algal biomass and energy

François Maréchal, Jan Van Herle, Christian Ludwig, Shivom Sharma, Eya Nicodeme, Hossein Madi

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system oper ...

Rainfall as a driver of epidemic cholera: Comparative model assessments of the effect of intra-seasonal precipitation events

Andrea Rinaldo, Damiano Pasetto, Francisco Javier Perez Saez, Joseph Chadi Benoit Lemaitre, Carla Sciarra

The correlation between cholera epidemics and climatic drivers, in particular seasonal tropical rainfall, has been studied in a variety of contexts owing to its documented relevance. Several mechanistic models of cholera transmission have included rainfall ...

Balancing wind-power fluctuation via onsite storage under uncertainty: Power-to-hydrogen-to-power versus lithium battery

François Maréchal, Jan Van Herle, Ligang Wang, Yumeng Zhang

Imbalance costs caused by forecasting errors are considerable for grid-connected wind farms. In order to reduce such costs, two onsite storage technologies, i.e., power-to-hydrogen-to-power and lithium battery, are investigated considering 14 uncertain tec ...

High time-resolution simulation of E. coli on hands reveals large variation in microbial exposures amongst Vietnamese farmers using human excreta for agriculture

Ana Karina Pitol Garcia, Timothy R. Julian

Infectious disease transmission is frequently mediated by the environment, where people's movements through and interactions with the environment dictate risks of infection and/or illness. Capturing these interactions, and quantifying their importance, off ...

Chemical composition, nutrient-balancing and biological treatment of hand washing greywater

Odile Marie Clotilde Hervás de Nalda-Larivé, Eva Reynaert

On-site biological hand washing water treatment can improve global access to safe hand washing water, but requires a thorough understanding of the chemical composition of the water to be treated, and an effective treatment strategy. This study first presen ...

Virus inactivation in stored human urine, sludge and animal manure under typical conditions of storage or mesophilic anaerobic digestion

Tamar Kohn, Loïc Decrey

Viruses represent major disease transmitting agents carried by human excreta and animal manure. Understanding virus inactivation is therefore essential in preventing microbial spread due to inadequate treatment of these materials. Here, we investigated the ...
