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

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

Boxall, Joby (author), Blokker, E.J.M. (author), Schaap, Peter (author), Speight, Vanessa (author), Husband, Stewart (author)Discoloured drinking water, caused by elevated concentrations of organic and inorganic particles, is unacceptable. It occurs due to accumulation and subsequent mobilisation of material from within drinking water distribution infrastructure. Discolouration is currently partially explained by either the theories of cohesive layers or...journal article 2023

Yan, Bin (author), Blankert, Bastiaan (author), Vogt, Sarah J. (author), Vrouwenvelder, J.S. (author), Johns, Michael L. (author), Fridjonsson, Einar O. (author)In this study non-invasive low field magnetic resonance imaging (MRI) technology was used to monitor fouling induced changes in fiber-by-fiber hydrodynamics inside a multi-fiber hollow fiber membrane module containing 401 fibers. Using structural and velocity images the fouling evolution of these membrane modules were shown to exhibit...journal article 2023

Ahmad, J.I. (author)Drinking water distribution systems (DWDSs) are intended to supply hygienically safe and biostable water for human consumption. To supply aesthetically pleasant drinking water at the customers tap, water treatment and supply requires energy for production and distribution purposes (e.g. overall between 0.47 kWh/m<sup>3</sup> in the Netherlands)....doctoral thesis 2022

Ebrahimzadeh, S. (author), Wols, Bas (author), Azzellino, Arianna (author), Kramer, Franca (author), van der Hoek, J.P. (author)Powdered activated carbon (PAC) is a promising technology to reduce organic micropollutants (OMPs) in drinking water treatment plants and combined with biological treatment processes such as rapid sand filters (RSFs), has the potential to remove a broad range of OMPs during water treatment. However, the removal of OMPs by a combination of two...journal article 2022

Roy, M. (author), van Genuchten, Case M. (author), Rietveld, L.C. (author), van Halem, D. (author)Groundwater contaminated with arsenic (As) must be treated prior to drinking, as human exposure to As at toxic levels can cause various diseases including cancer. Conventional aeration-filtration applied to anaerobic arsenite (As(III)) contaminated groundwater can remove As(III) by co-oxidizing native iron (Fe(II)) and As(III) with oxygen (O...journal article 2022

Hasan, A. Rasem (author), Sidiq, Fajar (author), Huntjens, Patrick (author), Jafar, Hanan A. (author), Kroesen, J.O. (author)The research conducted within the Palestinian Dutch Academic Cooperation on Water (PADUCO) program confirms that capacitive electrodialysis (CED) has the potential of becoming the next innovation in water purification. It uses less energy (<0.5 kWh/m3 ) than reverse osmosis (3–10 kWh/m3 ) and is, in particular, promising for local small-scale...journal article 2022

Goedhart, R.C. (author), Müller, S. (author), van Loosdrecht, Mark C.M. (author), van Halem, D. (author)Iron in anaerobic groundwater is commonly removed by oxidation followed by sand filtration. This produces large volumes of iron(III)(hydr)oxide sludge with little value. Our research investigates the novel concept of anaerobic iron(II) recovery from groundwater as the valuable mineral vivianite (Fe<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub> • 8...journal article 2022

de Vries, Laura (author)Over the last years the Netherlands has often had to deal with droughts and water shortages during summer. This problem is caused by long periods without rain but with high evaporation rates and is enhanced by groundwater extraction for drinking water. Due to climate change, these droughts are expected to occur more often and become more severe....master thesis 2021

de Wit, Fleur (author)The aim of the research is to aid selection of Household Water Treatment and Storage (HWTS) technologies. By creating an overview of important criteria for choosing between HWTS in a certain context, information on trade-offs is gathered. To do so, an explorative assessment is made of HWTS preferences in various contexts.master thesis 2021

Kusumawardhana, Agung (author), Zlatanovic, L. (author), Bosch, Arne (author), van der Hoek, J.P. (author)The aim of this study was to assess the health risks that may arise from the implementation of greywater reuse and rainwater harvesting for household use, especially for toilet flushing. In addition, the risk of cross connections between these systems and the drinking water system was considered. Quantitative microbial risk assessment (QMRA) is...journal article 2021

Saadabadi, S.A. (author), van Linden, N. (author), Heinsbroek, Abel (author), Aravind, P.V. (author)This study investigates the feasibility of electricity production in a solid oxide fuel cell using methane recovered from groundwater as the fuel. Methane must be removed from groundwater for the production of drinking water to, amongst others, avoid bacterial regrowth. Instead of releasing methane to the atmosphere or converting it to carbon...journal article 2021

Roy, M. (author), van Genuchten, Case M. (author), Rietveld, L.C. (author), van Halem, D. (author)Arsenic (As) is a toxic element present in many (ground)water sources in the world. Most conventional As removal techniques require pre-oxidation of the neutral arsenite (As(III)) species to the negatively charged arsenate (As(V)) oxyanion to optimize As removal and minimize chemical use. In this work, a novel, continuous-flow As removal...journal article 2021
