Der volle Inhalt der QuelleIn the European water framework directive context, we have studied metals in urban wastewaters for their potential threat to natural water bodies. The ecotoxicological effects of metals strongly depend on their speciation, which is still difficult to determine in complex media such as wastewaters. This work aims to assess metal speciation in urban wastewaters and its evolution until wastewater discharge into receiving waters, particularly during the wastewater treatment process. In this way, the diffusive gradient in thin film technique (DGT) has been evaluated as a metal speciation tool for wastewaters. Then, this tool has been used to measured labile metal in various wastewater samples collected in various wastewater treatment plants. In addition, different laboratory experiments have been performed to assess organic matter biodegradtion effect on metal speciation during activated sludge treatment. We have validated the DGT technique for the study of metal speciation in urban wastewaters and a first characterisation of labile metals measured by DGT has been made. The laboratory work showed that organic matter biodegradation removes only stronger ligands, weak ligands being removed during activated sludge process probably through adsorption or flocculation processes. Measurements performed on field samples showed that wastewater treatment plant effect on labile metal was variable and does not seem to depend on the treatment process or residence time within the system

Der volle Inhalt der QuelleThe work presented in this thesis concerns the development of an optimization methodology for control laws of wastewater treatment plants. This work is based on the use of WWTP process models in order to simulate their operation. These simulations are used by a multi-objective genetic algorithm, NSGA-II. This optimization algorithm allows the search of optimal solutions when multiple objectives are considered (e. G. The effluent quality, energy consumption, etc. ). It also enables the visualisation of compromises arising between various control laws as well as their respective best domains of application. In a first part of this work, the optimization methodology in developed around four main axes: the conception of a robust simulation procedure, the choice of input datasets for the simulations, the choice of objectives and constraints to consider and the evaluation of long term performances and robustness of control laws. This methodology is then applied on the literature case study of BSM1. In a second part of the work, the methodology is applied on the real case study of Cambrai wastewater treatment plant. This application includes the development of new aspects like the generation of dynamic input datasets out of daily monitoring measurements of the wastewater treatment plant, as well as the simulation of control laws based on oxydo-reduction potential measurements. This application allowed to analyze the compromises between the control law currently tested on the wastewater treatment plant and a new control law foreseen. The benefits of this modification could hence be clearly observed

Der volle Inhalt der QuelleThis thesis is part of phase 5 of the "OPUR: Urban Pollutants Observatory" program and aims to enhance the understanding and elimination of pharmaceuticals (pharmaceutical residues) in the context of urban wastewater treatment processes. The presence of pharmaceuticals in urban wastewater is primarily attributed to widespread drug use in urban areas, particularly through human excretion. The insufficient removal of these pharmaceuticals by wastewater treatment plants is the main cause of their presence in aquatic environments.To mitigate the risks associated with these micropollutants for aquatic flora and fauna, the addition of an advanced (tertiary) treatment to conventional wastewater treatment plants is one of the possible solutions. This approach would result in the reduction of the concentration of these emerging micropollutants in wastewater plant effluents.The significance of this study lies in the use of performic acid, a disinfectant employed to improve the quality of effluent discharged in the Seine River by the wastewater treatment plants in preparation for the 2024 Olympic and Paralympic Games to be held in Paris. Thus, this study aims to optimize the conditions for using this disinfectant, either individually or in conjunction with other oxidants in tertiary (advanced) oxidation processes, for the removal of pharmaceuticals.Various experiments, initially conducted using deionized water, revealed the pronounced yet selective reactivity of performic acid towards organic compounds containing reduced sulfur or deprotonated tertiary amines, with the primary oxidation mechanism involving the transfer of an oxygen atom.In urban wastewater, performic acid exhibits relatively high reactivity with the pharmaceuticals under investigation, and their removal is significantly influenced by the diverse constituents present in the effluent. Some of these constituents could activate performic acid, thereby generating reactive species that can effectively reduce a greater number of pharmaceuticals. Furthermore, the results demonstrate the efficacy of performic acid in eliminating polar organic micropollutants, a task often challenging for conventional treatment processes. The combination of performic acid with UV-C photolysis or ozone significantly improved the removal of pharmaceuticals resistant to performic acid alone

Der volle Inhalt der QuelleWhile membrane bioreactors (MBR) have been broadly applied to wastewater treatment, a comprehensive study of the aging of membrane materials under operating conditions of MBR at full-scale is necessary in order to understand and to anticipate it. Thus, the present research aim (i) to analyse the chemical action of sodium hypochlorite to commercial polyvinylidene difluoride (PVDF)/Polyvinylpyrrolidone (PVP) hollow fibers used in MBR, (ii) to describe membrane ageing of such materials in urban wastewater full-scale MBR based on a coupled characterization of harvested membranes and full-scale process indicators. To that end, ZeeWeed® 500D membranes were aged at bench-scale by single soaking in hypochlorite solution at a concentration (1000 ppm) and pH (9.0) similar to MBR cleaning protocols. In addition, membranes were sampled between 2016 and 2021 from modules from two urban wastewater treatment plants (capacities of 50,000 m3/d and 300,000 m3/d, respectively). Simultaneously, process data were collected and analyzed. Both bench-scale and full-scale aged hollow-fibers were characterized using similar analytical methods and compared considering the chlorine exposure dose (C x t). Significant differences were found between ageing mechanisms at both scales. At bench-scale, membranes presented stable mechanical properties. Three distinctive phases were observed for the changes on intrinsic permeability with an initial increasing phase up to a C x t of 78,000 ppm.h (+ 90% with respect to the initial permeability), because of hydrophilic agent degradation and the formation of small pores (diameter < 20 nm). Then, a decreasing phase is observed (from 78,000 ppm.h to 150,000 ppm.h), caused by a decline in porosity, likely due to a restructuration of PVDF chains. After 150,000 ppm.h, intrinsic permeability seemed to fluctuate around its initial values. At full-scale, a decline in mechanical properties is highlighted, probably linked to the dynamic conditions in the MBR (i.e. filtration, aeration and backwashing). Moreover, an increase in permeability is observed during the studied period (< 98,000 ppm.h) because of a more pronounced oxidation/dislodgement of PVP molecules (25% vs 40% from the initial PVP content, for full- and bench-scale respectively) leading to a higher porosity and the appearance of bigger pores (diameter > 40 nm). These changes favored irreversible fouling in contrary to bench-scale ageing. At full-scale, permeability index (the ratio of permeate flux and transmembrane pressure during the process) after each cleaning-in-place protocol decreases to around 20% over the studied period for both facilities. This decline is well correlated to the PVP content and intrinsic permeability, allowing the determination of key indicators to monitor membrane ageing. This study showed that understanding the mechanisms behind the action of NaOCl on supported PVDF membranes may not represent what actually occurs at full-scale operation. A non-negligible contribution of filtration conditions, mechanical stress due to aeration and backwashes, and residual fouling, specific to onsite operating conditions, may significantly change ageing mechanisms. Continuous autopsies of harvested fibers over the years and monitoring consistent full-scale operating indicators are still needed

Der volle Inhalt der QuelleOxygen renewal, as a prominent phenomenon for aerobic bacterial activity, deeply impacts Vertical Flow Constructed Wetland (VFCW) treatment efficiency. We introduce a multiphase model able to simulate multi-component transfer in VFCWs. It is based on a two-phase flow module, and a transport module. The flow module can quantify both water and air velocities throughout the filter during operation. The reactive transport module follows dissolved and gaseous oxygen concentrations, and the transport of solutes such as ammonium and readily biodegradable COD (Chemical Oxygen Demand). The consumption of components is governed by Monod-type kinetics. Heterotrophic and autotrophic bacteria, which are responsible for COD and ammonium degradation respectively, are part of the model components. The kinetics are based on the Constructed Wetlands Model 1. The results from the simulation tool were compared with existing experimental data, and two kinds of operation with VFCWs were investigated. The authors show strong interplay between oxygen renewal and bacterial consumption in case of sequential batch feeding with transient flooding of surface. Oxygen renewal is essentially convection mediated in such operation, while convection is not significant in non-flooding operation. Simulated bacterial patterns are impacted by the operation, both quantitatively and spatially. From a modelling point of view, the authors highlight some limitations of the biological model : the description of bacterial lysis processes needs to be enhanced, as well as ammonium adsorption to organic matter

Der volle Inhalt der QuelleElimination of excess sludge produced by biological wastewater treatment is an important issue of the next decade. Due to the constraints inherent to the current practices for sludge disposal, research efforts are focused on processes that reduce sludge production simultaneously to treating wastewater. The association of a chemical oxidation step (with ozone) with an activated sludge process can lead to a significant reduction of sludge production. Experimental and simulation approaches, were employed to analyse the main mechanisms of sludge production. Results showed the major influence of the accumulation of particular inert organic compounds coming from the influent and from the decay of biomass. Il ozonation treatment improves the biodegradability of those compounds, simulations confirms that total reduction of excess sludge production could be reached. Batch experiments of sludge ozonation show the solubilising effect if ozone and also demonstrate the biodegradability improvements of the solubilised matter and significant inactivation of biomass. The obtained results allow generation of a simulation model on the effect of ozone on sludge. Using this model combined with the existing biological model confirms the potential of the combined process. Continuous experiments at pilot scale confirm that the association of ozonation treatment with an activated sludge process allows total reduction of excess organic sludge production and also leads to the reduction of mineral sludge production. The optimization of the way of applying ozone (dosage, treatment frequency) appears to be a key point to guarantee the efficiency of the ozonation treatment. The obtained data show that ozone treatment lead to the production of non settleable refractory COD in the effluent. Significant improvements in sludge settling characteristics and conservation of nitrifying activity are also observed. The results of this work confirm the applicability of the combined process
