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

Prest, Emmanuelle I. (author), Martijn, Bram J. (author), Rietveld, Matthijs (author), Lin, Y. (author), Schaap, Peter G. (author)Sediment formation in drinking water distribution systems can lead to brown water at customer taps. Previous studies have shown that sediment formation is closely linked with (micro)biological processes in the distribution system, however the mechanism is not fully understood. Most available studies on discoloration or sediment formation...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

(author), Laureni, M. (author), Weissbrodt, D.G. (author)Drinking water treatment plants (DWTPs) are designed to remove physical, chemical, and biological contaminants. However, until recently, the role of DWTPs in minimizing the cycling of antibiotic resistance determinants has got limited attention. In particular, the risk of selecting antibiotic-resistant bacteria (ARB) is largely overlooked in...journal article 2023

Amorocho Daza, H.D. (author), van der Zaag, P. (author), Sušnik, J. (author)Water enables health, education, and economic well-being opportunities for humanity. Access to basic water and sanitation services, freshwater variability, and water storage are some of the dimensions that may impact on human development worldwide. Yet few studies quantitatively explore the relationship between water and human development....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

Hartmann, J. (author)“Access to safe drinking water is a fundamental human need and, therefore, a basic human right. Contaminated water jeopardizes both the physical and social health of all people”: such is the importance of safe drinking water, as stated by Kofi Annan, former Secretary-General of the United Nations, on World Water Day 2001. While some countries...doctoral thesis 2022

Li, Jun (author), Ren, Anran (author), van der Mark, Ed (author), Liu, G. (author)Drinking water quality deteriorates from treatment plant to customer taps, especially in the plumbing system. There is no direct evidence about what the differences are contributed by plumbing system. This study compared the water quality in the water main and at customer tap by preparing a sampling tap on the water main. The biomass was...journal article 2022

Zhai, Yujia (author), Liu, G. (author), van der Meer, Walter G.J. (author)The presence of newly emerging pollutants in the aquatic environment poses great challenges for drinking water treatment plants. Due to their low concentrations and unknown characteristics, emerging pollutants cannot be efficiently removed by conventional water treatment processes, making technically, economically, and environmentally...journal article 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

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

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

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

Moerman, Andreas (author), van Bel, Nikki (author), Oesterholt, Frank (author), de Laat, Vincent (author), Blokker, E.J.M. (author)Climate change demands for sustainable options for heating and cooling of buildings. Low-temperature thermal energy can be abstracted from the drinking water distribution system (DWDS); this is called thermal energy from drinking water (TED). The possible use of TED as a secondary function of the DWDS raises the question whether this...book chapter 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

Wang, Siyuan (author)Drinking water temperature is an essential parameter for water quality related to the physical, chemical and biological processes in water. However, in many countries, the drinking water temperature has not been taken seriously and was excluded from water quality standards. For example, in the Netherlands, the temperature of drinking water...master thesis 2021

Kramer, O.J.I. (author)In drinking water treatment plants, multiphase flows are a frequent phenomenon. Examples of such flows are pellet-softening and filter backwashing where liquid-solid fluidisation is applied. A better grasp of these fluidisation processes is needed to be able to determine optimal hydraulic states. In this research, models were developed, and...doctoral thesis 2021

Koudijs, Nienke (author)Groundwater is an excellent source for the production of drinking water due to its low concentration of microorganisms and contaminants. The main contaminants present in groundwater are iron, ammonium and manganese, which are sequentially removed in rapid sand filters by a combination of biological and chemical processes. Currently, limited...master thesis 2021
