Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conven-
tional activated sludge system, allowing space and energy savings. This process is particularly
suited for biological phosphorus removal, avoiding use of coagulant ...

Aerobic granular sludge (AGS) is an emerging technology offering an alternative wastewater treatment with a reduced footprint compared to conventional activated sludge systems. Basic understanding of AGS processes has mainly been obtained in laboratory-sca ...
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 ...
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 ...
