The increasing use of nanoparticles and the market to commercialize this innovative technology requires a deeper understanding of the behavior of nanoparticles (NPs) and the resulting consequences in an environmentally The increasing use of nanoparticles and the market to commercialize this innovative technology requires a deeper understanding of the behavior of nanoparticles (NPs) and the resulting consequences in an environmentally relevant matrix. However, since the fate and behavior of nanoparticles is largely unknown to the environment, this study was done to investigate the key properties of nanoparticles, parameters to describe them and to discuss how these parameters can influence their fate and behavior in the natural environment. The core goal of this discussion is to relate sludge treatment to relevant properties of the nanoparticle, which may interact with a range of substances naturally present in wastewater treatment plants (WWTPs) and activated sludge. Understanding these properties is necessary for interpreting the fate of nanoparticles and predicting their effects in the actual environment. Environmentally matrix are challenging to investigate, for instance as in sludge and anaerobic sludge stabilization. According to the literature, it will be assumed that about 95% of the NPs entering the WWTP end up in the sludge. This work reports on the investigation and observation of NPs behavior in the different stages, using different experiments and metering devices. The different experiments include (i) characterization of NPs before their application (NanoSight), (ii) behavior analysis in terms of kinetic transformations (Turbiscan), (iii) long- and short-term analysis of NPs effects on anaerobic sludge stabilization (laboratory fermentation plants). The characterization represents the current size distribution of the NPs in a controlled environment (H2O). Size is one of the defining properties of NPs, which causes changes in physical and chemical properties of NPs compared to their original materials. The results show that the distribution of NPs depends on the type of particle, surface coating and dispersion concentration. These parameters are subject to permanent changes in sludge. That is why an exact allocation to the effects seems almost impossible. Characterization is indispensable for the subsequent comprehension of the effects, and for the understanding of findings, which may result from the behavioral analysis, as well as from the effect analysis. The behavioral analysis was carried out by Turbiscan technology to consider relevant sludge parameters and substances (Chemical Oxygen Demand COD, Polymers, Humic acids, digestion process) to the behavior of NPs in sludge. The initial aim was to progressively add of representative substances to approximate the experiment to natural conditions. The phase separation detection identified a clear sedimentation behavior in all samples. To explain this and the kinetic modification as well as the resultant kinetic instability, the NPs’ diameter (particle… Advisors/Committee Members: Luxembourg Institute of Science & Technology - LIST [research center], Hansen, Joachim [superviser], Gutleb, Arno [superviser], Greger, Manfred [superviser], Leyer, Stephan [member of the jury], Emmerling, Christoph [member of the jury], Rahimi, Anahita Bahareh [member of the jury].
