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.

Strubbe, Laurence (author), van Dijk, E.J.H. (author), Deenekamp, Pascalle J.M. (author), van Loosdrecht, Mark C.M. (author), Volcke, Eveline I.P. (author)In the pursuit of reducing carbon footprint and in view of increasing energy prices, energy efficiency is more important than ever before. Batch-wise operated aerobic granular sludge reactors consume up to 50% less energy compared to conventional activated sludge systems because pumping energy is reduced and mixing equipment is not needed....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

Cerruti, M. (author), Kim, J.H. (author), Pabst, Martin (author), van Loosdrecht, Mark C.M. (author), Weissbrodt, D.G. (author)Purple bacteria (PPB), anoxygenic photoorganoheterotrophic organisms with a hyper-versatile metabolism and high biomass yields over substrate, are promising candidates for the recovery of nutrient resources from wastewater. Infrared light is a pivotal parameter to control and design PPB-based resource recovery. However, the effects of light...journal article 2022

Pei, R. (author), Estevez Alonso, A. (author), Ortiz-Seco, Laura (author), van Loosdrecht, Mark C.M. (author), Kleerebezem, R. (author), Werker, A. (author)Municipal activated sludge can be used for polyhydroxyalkanoate (PHA) production, when supplied with volatile fatty acids. In this work, standardized PHA accumulation assays were performed with different activated sludge to determine (1) the maximum biomass PHA content, (2) the degree of enrichment (or volume-to-volume ratio of PHA...journal article 2022

Zhang, Mengru (author), Han, Fei (author), Liu, Zhe (author), Han, Yufei (author), Li, L. (author), Zhou, Weizhi (author)The contradiction between theoretical metabolism of ammonium assimilation and experiential understanding of conventional biosystems makes the rational optimization of the ammonium-assimilating microbiome through carbon to nitrogen (C/N) ratios perplexing. The effect of different C/N ratios on ammonium-assimilating biosystems was investigated...journal article 2022

(author), Xevgenos, Dimitris (author)Although the energy transition results in decreased use of coal for power production, hard coal extraction will continue due to its importance in steel production and coal mine wastewater will continue generating after mines closure. The coal mining sector produces wastewater which results in environmental burdens and often contains valuable...journal article 2022

Hao, Xiaodi (author), Wu, Daoqi (author), Li, Ji (author), Liu, Ranbin (author), van Loosdrecht, Mark C.M. (author)Entropy is a concept defined by the second law of thermodynamics. Applying this concept to the world we live in, entropy production must be minimized and negentropy (negative entropy production) should be accelerated, in order to produce a healthy and stable ecological system. The present wastewater treatment, however, contributes to entropy...journal article 2022
