Full textOxygen 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

Full textElimination 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

Full textThe fate of estrogens and estrogenic activity through a sewage treatment plant were studied combining chemical and biological assessments. The behaviour of estrogens and endocrine-disrupting activities was also investigated during sludge anaerobic digestion or composting after validation of a specific analytical method. Finally, the bacteria involved in the degradation of estrogens were characterised using both classical and molecular microbiological methods. The estrogens and estrogenic activity are efficiently removed by biodegradation during urban sewage treatment. Despite slightly sorption of estrogens on sludge, persistence of these compounds and endocrine-disrupting activities was observed through anaerobic digestion and composting process. The estrogens-degrading consortia consist of until now uncultured species or bacteria already known to degrade estrogens or others organic pollutants. Brevundimonas diminuta was involved in the degradation of estradiol

Full textIn 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

Full textIn the purpose to reduce waste amount, the electro-dewatering process is a promising technique to efficiently withdraw a large part of the water included in wastewater sludge. This PhD thesis contributes in various ways to the study of this technique. Lab-scale experiments showed correlations between dewatering kinetics and energy consumption of the process. Moreover, a new model, relatively simple, is proposed to study and simulate the process. This model highlights the main phenomena involved in the electro-dewatering. Finally, a study of the migration of chemical species during the dewatering process is carried out thanks to an analytical protocol measuring ions in filtrates and sludge slices.1

Full textThis study describes and analyses the interactions which exist between the biological medium specificities coming from a submerged Membrane Bioreactor (MBR) and fouling. The MBR was compared with an activated sludge process, both fed with the same urban wastewater. The purification efficiencies of both processes were compared for the same operating conditions and at different sludge ages. The influence of membrane and sludge age on supernatant (soluble polymer, COD) and floc characteristics (diameter, fractal dimension, bound exopolymer, sludge volume index, turbidity) was analysed. Sludge production for both systems were calculated and confronted with models. Moreover, we mentioned the main mechanisms implied in long and short term fouling. Finally, the specific role of soluble/colloidal proteins and polysaccharides on deposit structuring was underlined

Full textBiofim reactors are used in wastewater treatment for simultaneous COD and nitrogen removal. This biological process is based on a complex bacterial consortium, composed of both autotrophic and heterotrophic bacteria, associated in “biofilm”. The coexistence of these populations results of a microbial competition for both the substrates and the space. This microbial competition potentially leads to process failures as decreases of the removal rates, and thus its mechanisms must be understood. In this way, the objectives of this work were: (i) to develop a model of biofilm growth, (ii) to characterize the detachment mode and its impact on the competition, (iii) and to analyze the impact of the environmental growth conditions on the competition. The main results of this work are the following : a 1-D biofilm model, since the structure allows predicting population dynamics and the biofilm reactor performances, was developed. This is a multi-species and multi-substrates model, which assumes a continuous surface detachment. An experimental study of the detachment mode was performed. Different biofilms were grown under different various and contrasted growth conditions in Couette-Taylor Reactors. Erosion process was defined as a continuous surface detachment of small particles coupled with dynamic volume events detaching large particles. Using the model, different detachment modes in terms of fraction of biofilm thickness detached and in terms of frequency were tested. The dynamic volume events determine the heterotrophic growth at the biofilm surface, and thus the availability of oxygen inside the biofilm. If oxygen is limiting in the inner zone of the biofilm, the autotrophic growth is limited or impossible. By impacting the oxygen availability, the dynamic volume events consequently govern the result of the autotrophic-heterotrophic competition. Under oxygen-limiting conditions, the comparison between numerical and experimental results shows that a simple 1-D model overpredicts the advantage of the heterotrophic growth. The impact of more complex processes on autotrophic-heterotrophic coexistence was thus evaluated. Specific heterotrophic detachment and particulate convection were shown to favour the autotrophic growth and thus the autotrophic-heterotrophic coexistence. Finally, 1-D models considering simple biological and physical processes leads to a strict stratification of the functionalities. The following question is highlighted by this work: Is the strict stratification of the microbial functionalities predicted by simple 1-D model can potentially change the result of the autotrophic-heterotrophic competition ?

Full textThe 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
