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

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

Pryce, David (author), Kapelan, Z. (author), Memon, Fayyaz A. (author)In the plight for sustainable development and to support net zero ambitions for climate change mitigation, a broad range of aeration strategies have been developed with the hope of improving efficiency to minimize environmental and economic costs associated with the wastewater treatment processes. However, a balance is levied between reducing...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

Prot, T.J.F. (author), Korving, L. (author), van Loosdrecht, Mark C.M. (author)In a wastewater treatment plant (WWTP), several sludge streams exist and the composition of their liquid phase varies with time and place. For evaluating the potential for formation of precipitates and equilibria for weak acids/bases, the ionic strength and chemical composition need to be known. This information is often not available in...journal article 2022

Pawar, Nikhil Dilip (author), Harris, Steve (author), Mitko, Krzysztof (author), Korevaar, G. (author)Coal-mine effluent treatment has the potential to both reduce the environmental impact of the effluent and provide economic opportunities by recovering valuable minerals and clean water. In this study, we modeled a novel treatment process, which includes nanofiltration (NF), two-step crystallization, reverse osmosis (RO), electrodialysis (ED),...journal article 2022
