Appropriate technologies are needed for disinfection of wastewater to allow safe reuse. Slow sand filtration is a simple technology used for pathogen and particle removal in drinking water purification. We investigated removal of fecal indicator bacteria relevant for wastewater reuse, particle removal, and runtime in slow sand filtration of secondary(More)
Due to increasing water scarcity, appropriate technologies are needed for disinfection of wastewater to enable safe reuse. Research on hygienisation of secondary effluent using slow sand filters is very limited but promising with removal of fecal indicator bacteria of >2log-units. A quantitative description of the processes leading to bacteria removal is(More)
Slow sand filtration (SSF) is an effective low-tech water treatment method for pathogen and particle removal. Yet despite its application for centuries, it has been uncertain to which extent pathogenic microbes are removed by mechanical filtration or due to ecological interactions such as grazing and competition for nutrients. In this study, we quantified(More)
