Soodan, Akhilesh (author)Groundwater is an essential source of drinking water, and it often contains contaminants in the form of dissolved metal ions that pose health risks and affect its suitability for consumption. Removal of these contaminants by conventional treatment methods, such as oxidation and filtration, results in additional treatment steps for managing...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

Wu, HAO (author)Microorganisms may cause problems in drinking water distribution system (DWDS). It is hard to control and always forms the biofilm, which can result in the deterioration of drinking water quality. At household’s tap, due to the favorable conditions, which incurs an easier formation of biofilm. Therefore, the idea of secondary disinfection at...student report 2020

Goense, Anna (author)Fog harvesting is a sustainable drinking water solution for arid climates. Previous studies have developed an analytical model to predict the fog water collection efficiency as a product of aerodynamic and deposition efficiency as independent factors. In this study, we tested the assumption that deposition efficiency stays unchanged when the...master thesis 2018

Kattenberg, Lotte (author)Due to climate change, our society must become more climate resilient, and this is also the case for drinking water distribution systems. Climate change implicates that temperatures of the atmosphere are getting higher. This may lead to that the drinking water may become warmer. One of the consequences of climate change is that alternative ways...student report 2018

Bandinu, Giacomo (author), Barendsen, Lot (author), Delfos, Jeroen (author), Janse, Arnout (author), Overtoom, Irene (author)The goal of this project is to develop a design for Dala’s water system that deals with challenges of the township in a sustainable way. Dala is a township of Yangon, Myanmar’s economic centre. It is located directly South of the central business district (CBD), across the Yangon river. The area is now largely underdeveloped, but in 2021 it will...student report 2017

Chen, Z. (author)The drinking water distribution network is a sealed and pressurized system which attached numerous biofilm and microorganism due to the long-time operation. In a foreseeable future, Oasen will adopt reverse osmosis to treat drinking water and thus the nutrient (biodegradable compounds) in drinking water will be slight. In that case, biofilms...master thesis 2016

Admiraal, M. (author), Couasnon, A. (author), Huijzenveld, T. (author), Hutten, R. (author), Schölvinck, O. (author), Van Veen, N. (author)In Nicaragua, active research for arsenic started in 1996, after the first case of arsenic poisoning was reported in a rural community. Arsenic concentrations present in drinking water cause chronic poisoning, which depending on the exposure, lead to several life-threatening long term effects. It is however unknown to what extent this...student report 2015

Schoonenberg Kegel, F. (author)Aeration and rapid sand filtration are common practice for the treatment of iron, manganese and ammonium containing ground water for more than a century. Nevertheless, this process has not become obsolete. On the contrary, this thesis assumes that enhanced rapid sand filters remain standard treatment technology in the 21st-century. Iron can be...master thesis 2015

Wessels, P.H. (author)Oasen has set itself the goal to “produce water of an impeccable quality and to delivery it flawlessly to its customers”. In formulating this goal, Oasen expresses its concern for unknown pollutants and the increasing concentrations of organic micro-pollutants in its source waters (primarily anaerobic groundwater). To achieve this goal, the...master thesis 2014

Moerman, A. (author)Domestic drinking water systems are the final stage of the transport process to deliver potable water to the customers tap. Although these systems play an important role in drinking water quality only several researches on the edge of residence time and temperature were performed during the past. These two parameters play an important role in...master thesis 2013

Van der Wees, M. (author)The drinking water treatment industry is becoming increasingly centralized and automated. This requires a different operator training approach then the traditional on the job training. To address this requirement a drinking water treatment plant simulator was developed. A major advantage of such a simulator might be that the normally very slow...master thesis 2009
