de Graaff, D.R. (author)Increase in sea level will lead to an increase in salinity in domestic wastewater systems. In order to anticipate its effects on biological wastewater treatment, the impact has to be assessed with lab-scale experiments. Aerobic granular sludge (AGS) is a successful technology for simultaneous removal of organic carbon (COD), nitrogen, and...doctoral thesis 2020

Huang, Hongjie (author)Water is one of the long-standing problems in Sint Maarten. Water supply is scarce while water demand is high. Water pollution and incomplete infrastructure also needs to be tackled. How can a cluster scale decentralized water management system solve water challenges in the hurricane-prone environment of Sint Maarten is the research question....master thesis 2020

van der Poel, Suzanne (author)Due to increasing water consumption and stress on natural water resources, enhanced treatment of wastewater and reuse of water are becoming more important. Treated municipal wastewater has potential to be used for irrigation purposes, but pathogens are a major concern to protect environmental and human health. Therefore, an advanced treatment...student report 2020

Kooijman, G. (author), de Kreuk, M.K. (author), Houtman, C. (author), van Lier, J.B. (author)Literature frequently reports that colloids in aqueous matrices sorb a large fraction of pharmaceuticals. Since coagulation/flocculation removes colloids, it is expected that coagulation/flocculation in principle should be useful in concentrating pharmaceuticals in wastewater treatment, which would facilitate the treatment of these refractory...journal article 2020

Calderon Franco, D. (author), van Loosdrecht, Mark C.M. (author), Abeel, T.E.P.M.F. (author), Weissbrodt, D.G. (author)The free-floating extracellular DNA (exDNA) fraction of microbial ecosystems harbors antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs). Natural transformation of these xenogenetic elements can generate microbial cells resistant to one or more antibiotics. Isolating and obtaining high yield exDNA is challenging due to its low...journal article 2020

Guo, H. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Full-scale aerobic granular sludge technology under the trade name Nereda® has been implemented for municipal, as well as industrial wastewater treatment. Owing to the operational reactor procedures, two types of waste aerobic granular sludge can be clearly distinguished: 1) aerobic granular sludge selection discharge (AGS-SD) and 2) aerobic...journal article 2020

van den Berg, L. (author), van Loosdrecht, Mark C.M. (author), de Kreuk, M.K. (author)Biofilm and granular sludge processes depend on diffusion of substrates. Despite their importance for the kinetic description of biofilm reactors, biofilm diffusion coefficients reported in literature vary greatly. The aim of this simulation study was to determine to what extent the methods that are used to measure diffusion coefficients...journal article 2020

Cerruti, M. (author), Stevens, B. (author), Ebrahimi, S. (author), Alloul, A. (author), Vlaeminck, Siegfried E. (author), Weissbrodt, D.G. (author)Mixed-culture biotechnologies are widely used to capture nutrients from wastewater. Purple non-sulfur bacteria (PNSB), a guild of anoxygenic photomixotrophic organisms, rise interest for their ability to directly assimilate nutrients in the biomass. One challenge targets the aggregation and accumulation of PNSB biomass to separate it from the...journal article 2020

Lanko, Iryna (author), Flores, Laura (author), Garfí, Marianna (author), Todt, Vladimir (author), Posada Duque, J.A. (author), Jenicek, Pavel (author), Ferrer, Ivet (author)In this study the environmental impact of the anaerobic digestion (AD) of sewage sludge within an activated sludge wastewater treatment plant (WWTP) was investigated. Three alternative AD systems (mesophilic, thermophilic, and temperature-phased anaerobic digestion (TPAD)) were compared to determine which system may have the best...journal article 2020

Guo, H. (author), Felz, S. (author), Lin, Y. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Aerobic granular sludge (AGS) technology is an alternative to conventional activated sludge to reduce the process footprint and energy consumption. Strategies for the efficient management of its produced biomass, that is grown in a granular morphology as well, need further development. Anaerobic digestion (AD) is commonly applied in waste...journal article 2020

Wahaab, Rifaat Abdel (author), Mahmoud, Mohamed (author), van Lier, J.B. (author)Over the past 4 decades, the increasing amounts of excess sludge from municipal wastewater treatment plants (WWTPs) represent a challenge toward achieving the sustainability of the drinking water and sanitation sector in Egypt, resulting in a serious environmental pollution due to the uncontrolled use of non-stabilized sludge. Here, we report a...journal article 2020

van Dijk, E.J.H. (author), Pronk, M. (author), van Loosdrecht, Mark C.M. (author)The settling behavior of aerobic granular sludge (AGS) in full-scale reactors is different from the settling of normal activated sludge. Current activated sludge models lack the features to describe the segregation of granules based on size during the settling process. This segregation plays an important role in the granulation process and...journal article 2020
