Middelbeek, Lisanne (author)This research addresses the issue of rising soil temperatures, driven by climate change. As the Drinking Water Distribution System (DWDS) is located in the sub-surface, the drinking water temperature in the distribution mains attains this rising soil temperature. Because the temperature of drinking water is an important determinant of water...master thesis 2024

Roy, M. (author), Kraaijeveld, E. (author), Gude, J.C.J. (author), van Genuchten, Case M. (author), Rietveld, L.C. (author), van Halem, D. (author)Long-term consumption of groundwater containing elevated levels of arsenic (As) can have severe health consequences, including cancer. To effectively remove As, conventional treatment technologies require expensive chemical oxidants to oxidise neutral arsenite (As(III)) in groundwater to negatively charged arsenate (As(V)), which is more...journal article 2024

Wang, Di (author), Ren, Anran (author), Yao, Mingchen (author), Hu, Bin (author), van der Meer, Walter (author), Liu, G. (author)Drinking water biosafety has become an increasing concern for public health. Chlorination is widely used as the main disinfection strategy worldwide but has clear and well-known byproduct issues. The Netherlands has successfully demonstrated unchlorinated approach for almost 20 years but has not been widely adopted by other countries. To...journal article 2024

Abkar, Leili (author), Aghili Mehrizi, Amirreza (author), Jafari, Morez (author), Beck, Sara E. (author), Ghassemi, Abbas (author), van Loosdrecht, Mark C.M. (author)Reverse osmosis (RO) systems offer a viable solution for treating brackish water (BW), a common but underutilized water resource. However, the energy-intensive nature of brackish water reverse osmosis (BWRO) systems poses affordability challenges to water supply, necessitating a focus on minimizing their energy consumption to support SDG6's...journal article 2024

(author)Escherichia coli (E. coli) plays a central role as an indicator for fecal contamination to predict the possible presence of microbial pathogens in drinking water. Current detection methods for E. coli are based on time-consuming culture-based techniques. There is a strong need for methods to detect fecal contamination rapidly in distributed...journal article 2024

Frey, Veronika (author), Kraaijvanger, Joost (author), Lorenzen da Silva, Valentin (author), Oudenes, Derby (author)In this project, student teams from Universidad San Francisco de Quito and Delft University of Technology worked together to provide safe drinking water in Ecuador. We used M-100 chlorinators from the company WaterStep, donated by Water Ambassadors Canada, to chlorinate water in schools and communities. The journey involved testing water quality...student report 2023

van Ruiten, Joséphine (author)Globally, drinking water sources are polluted with poly- and perfluoroalkyl substances (PFAS). The toxicity and persistent properties of these industrial chemicals raised concerns about environmental and public health. As a result, drinking water companies are removing PFAS from drinking water using separation technologies. Anion exchange and...master thesis 2023

Straathof, Judith (author)UV disinfection is an efficient way to inactivate chlorine resistant protozoan pathogens such as Cryptosporidium parvum and Giardia muris. In the United States, regulatory UV disinfection credit is typically granted when turbidity is <1 NTU. However, studies show turbidity does not correlate well with UV dose responses and partial...master thesis 2023

Besseling, Roos (author), van Marrewijk, Josine (author), Slokker, Marloes (author), van der Zwet, Ilse (author)In many places in Uganda, people do not have a connection to the drinking water supply system and there is a lack of treated water supply, meaning that people only have access to water a certain part of the day. As a result many people rely on springs, handpumps, rivers or lakes, of which the quality cannot be monitored or controlled. <br/><br/...student report 2023
