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

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

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

Pryce, David (author), Kapelan, Z. (author), Memon, Fayyaz A. (author)Limiting the introduction of excess nitrogen to natural water sources is a growing priority for water security and environmental health. This poses particular difficulties in urban environments where available land for potential solutions is limited. A promising option is the integrated fixed-film activated sludge (IFAS) process that requires...journal article 2023

Kokubo Roche, Akemi (author)Water scarcity problems will continue to exacerbate in many parts of the world, urging society to mitigate or adapt. Consequently, unconventional water resources, such as municipal wastewater, are becoming more relevant. This thesis aims to measure and evaluate the social impacts of wastewater treatment (WWT) systems potentially stemming from...master thesis 2022

Della Pietra, Diana (author)In our effort to control it, water in our cities has progressively been confined between lines, canalised or culverted underground, resulting in its gradual isolation and erasure from our sight and collective imagination. As freshwater availability and water-related hazards are brought to the forefront of sustainable development goals, the long...master thesis 2022

Toja Ortega, S. (author), van den Berg, L. (author), Pronk, M. (author), de Kreuk, M.K. (author)In aerobic granular sludge (AGS) reactors, granules of different sizes coexist in a single reactor. Their differences in settling behaviour cause stratification in the settled granule bed. In combination with substrate concentration gradients over the reactor height during the anaerobic plug-flow feeding regime, this can result in functional...journal article 2022
