Huang, Wenqing (author)The excessive nitrogen in waterbodies, often caused by the discharge of ammonia-rich wastewaters, leads to eutrophication, disrupting aquatic ecosystems. Wastewater treatment plants play an important role in the removal and recovery of nitrogen from wastewater streams, thereby preventing pollution. Air stripping in combination with acid...master thesis 2024

Strubbe, Laurence (author), van Dijk, E.J.H. (author), Carrera, Paula (author), van Loosdrecht, Mark C.M. (author), Volcke, Eveline I.P. (author)The aerobic granular sludge (AGS) process treats wastewater with a significantly lower footprint and energy consumption compared to conventional activated sludge systems. Nevertheless, there is still potential for optimizing its performance, and mathematical models are most valuable tools to this end. Aeration energy consumption deserves...journal article 2024

(author), van Loosdrecht, Mark C.M. (author)Circular economy has become a popular subject, attracting attention from academics, practitioners, and policy-makers alike. However, despite the excitement surrounding it, the concept of circular economy has been criticized for being vague and having multiple interpretations from different fields. As a result, there is a lack of evidence and...journal article 2024

Niquice, Celma (author), Marques Arsenio, A. (author), Medema, G.J. (author), van Lier, J.B. (author)Faecal contamination across the lettuce value chain was assessed in Maputo, Mozambique. Escherichia coli was used as an indicator of faecal contamination, with concentrations ranging from 3.4 to 5.7 log units/100 ml in groundwater, river water and partially treated wastewater. Municipal tap water used to wash lettuce heads in the markets had...journal article 2024

Bhambhani, A. (author), Jovanovic, O. (author), van Nieuwenhuijzen, Arjen (author), van der Hoek, J.P. (author), Kapelan, Z. (author)Resources recovery can improve the economic efficiency and reduce the negative environmental impacts of municipal wastewater treatment plants (MWWTP). The recovered resources can also actively benefit the natural environment enabling a reciprocal relationship between human society and nature. Focusing on these benefits can reveal new resources...journal article 2024

Moradvandi, A. (author), Abraham, E. (author), Goudjil, Abdelhak (author), De Schutter, B.H.K. (author), Lindeboom, R.E.F. (author)This paper focuses on the development of linear Switched Box–Jenkins (SBJ) models for approximating complex dynamical models of biological wastewater treatment processes. We discuss the adaptation of these processes to the SBJ framework, showing the model's generality and flexibility as a class of switched systems that can offer accurate...journal article 2024

(author)Infrastructure in low-lying coastal areas faces challenges from climate change, sea level rise, and the impact of compound hazards. Dynamic adaptive pathways planning (DAPP) is increasingly being applied as a way of planning under deep uncertainty. Stress testing for robustness is an integral part of DAPP which provides decision-makers with...journal article 2024

JI, YUNING (author)With the development of industry, there is an increasing focus on environmental issues, while organic micro-pollutants (OMPs) have garnered significant attention as emerging contaminants in water. Due to the low concentration and small size, OMPs pose a challenge to retain in traditional low-pressure membrane filtration systems. Prior researches...master thesis 2023

Thiruvenkatachari, Priyadarshini (author)Elevated levels of ammonia in discharged water leads to eutrophication and potential toxicity in water bodies. To combat nitrogen pollution, strict ammonium discharge limits of 1 mgNH<sub>4</sub>-N/L standard is set by the water framework directory. In many cases, current wastewater treatment facilities struggle to consistently meet this...master thesis 2023

Feberwee, Kai (author)Throughout sub-Saharan Africa, agricultural activities in urban and peri-urban areas are threatened by urban sprawl. These activities are important not just for the livelihoods of those who take part in it, but also for the food security of the city. Historically, in Kumasi 40% of the crops in the city are sourced from urban and peri-urban...master thesis 2023
