Water and Waste Treatment
Présentation

Global Approach to the Water Cycle

The work of the Water and Waste Treatment team (TED) is organized around an integrated global vision of wastewater and waste treatment and recovery.

This systemic approach is based on a coupled experimentation-modeling-simulation approach of the processes to treat, reuse and valorize urban or industrial effluents (production of H2, CH4, heat; recovery of nutrients, metals, reuse, etc.). It aims to contribute to the major challenges of the 21st century and more particularly to the ecological and energy transitions.

To this end, the team develops multi-scale approaches to the treatment and recovery of liquid and solid effluents in suspension.

At the material scale, the team has the skills for specific characterizations such as rheology and bio-calorimetry.

At the process scale, the studies focus on the application of innovative mechanisms in biological, thermal or physico-chemical reactors. The characterization of transfer, material and kinetic quantities leads to the development of dedicated models.

These models are used within specific integrative methodologies when two or more processes are coupled. These methods are developed to determine the optimal operation of the coupling and/or the industrial site hosting these processes.

The themes developed in the TED team are articulated around the following three axes:

Pollution control axis 

dedicated to the dimensioning of water and waste treatment processes as well as to the understanding of the transfer mechanisms and reaction processes involved.

Sub-axes: bioreactors, reactive filters, OVH, gasification, rheology, calorimetry

Valorization axis 

in which studies are devoted to the optimization of processes and procedures for the material and/or energy recovery of effluents and waste (phosphorus recovery, production of energy carriers: H2, CH4, etc.)

Sub-axes: crystallization, bioH2 and energy carriers from biomass, recovery of nutrients, etc.

Integration axis 

focused on the study of the coupling of processes developed in the team associated with an approach to optimize flows by ad hoc methods of industrial symbiosis.

Sub-axis: process coupling, energy optimization, etc.

    Metabolic Exchange and Energetic Coupling between Nutritionally Stressed Bacterial Species: Role of Quorum-Sensing Molecules

    Formation of multispecies communities allows nearly every niche on earth to be colonized, and the exchange of molecular information among neighboring bacteria in such communities is key for bacterial success. To clarify the principles controlling interspecies interactions, we previously developed a coculture model with two anaerobic bacteria, Clostridium acetobutylicum (Gram positive) and Desulfovibrio vulgaris Hildenborough (Gram negative, sulfate reducing). Under conditions of nutritional stress for D. vulgaris, the existence of tight cell-cell interactions between the two bacteria induced emergent properties. Here, we show that the direct exchange of carbon metabolites produced by C. acetobutylicum allows D vulgaris to duplicate its DNA and to be energetically viable even without its substrates. We identify the molecular basis of the physical interactions and how autoinducer-2 (AI-2) molecules control the interactions and metabolite exchanges between C. acetobutylicum and D. vulgaris (or Escherichia coli and D. vulgaris). With nutrients, D. vulgaris produces a small molecule that inhibits in vitro the AI-2 activity and could act as an antagonist in vivo. Sensing of AI-2 by D. vulgaris could induce formation of an intercellular structure that allows directly or indirectly metabolic exchange and energetic coupling between the two bacteria.

    A comparative study of conventional activated sludge and fixed bed hybrid biological reactor for oilfield produced water treatment: influence of hydraulic retention time

    This study focuses on the development of a hybrid biological reactor for the treatment of synthetic oilfield produced water. To face increasingly strict regulations concerning produced water discharge, a fixed bed hybrid biological reactor (FBHBR) containing a combination of free activated sludge and a fixed biofilm support was compared to a conventional activated sludge reactor (CAS). After gradual microbial acclimation, a 133-day experiment showed that both bioreactors were able to efficiently remove phenol, toluene, xylenes, and polycyclic aromatic hydrocarbons (PAHs) from a synthetic wastewater with a chemical oxygen demand (COD) removal rate above 95%, at hydraulic retention times (HRT) of 24 h and 18 h, and that only the FBHBR was able to maintain high removal efficiency at an HRT of 12 h. Ecotoxicity tests showed that outlet waters from both bioreactors were non-toxic. Assessment of the bacterial population revealed notable differences between the CAS reactor and FBHBR. In particular, wider diversity was observed in the FBHBR. The marked similarity between the bacterial composition of the free sludge and that of the biofilm in the FBHBR suggests that biofilm detachment played an important part role in bacterial development in the free sludge.

    Generation of an O/W emulsion in a flow-focusing microchip: importance of wetting conditions and of dynamic interfacial tension

    6 To date, there is no information on the microfluidic emulsification of dibutyl adipate and 7 n-butyl acetate in water. Since these solvents are very suitable for microencapsulation by 8 interfacial polymerization, it is highly necessary to study the emulsification behavior of these 9 solvents in microchannel. This work shows that the microfluidic emulsification of these sol-10 vents in water may fail to obtain stabilized flow regimes. This is due to droplet coalescence 11 and wall wetting, even if a hydrophilic microchip is used. Hydrodynamic results show that 12 squeezing and dripping regimes are especially affected because of the wall wetting by the 13 dispersed phase. This difficulty can be circumvented by adding a surfactant (here Tween 14 80) into the aqueous phase. However, high surfactant concentrations (ten times the crit-15 ical micelle concentration) should be used for the water-dibutyl adipate system. Indeed, 16 comparison of flow maps for several surfactant concentrations seems to indicate that the 17 dynamic interfacial tension is higher than the one expected (equilibrium), for surfactant 18 concentrations lower than one hundred times the critical micelle concentration. The esti-19 mated diffusion time of Tween 80 is compared to the droplet formation time at different 20 conditions. The choice of more appropriate dimensionless numbers to represent flow maps 21 is also discussed. 22

    Dead-end and crossflow ultrafiltration process modelling: Application on chemical mechanical polishing wastewaters

    Dynamic simulation of ultrafiltration process is applied to the treatment of chemical mechanical polishing wastewater from microelectronic industry. The ultrafiltration of nanoparticles (NPs) contained in chemical mechanical polishing wastewater is modelled by using different mathematical equations, which are derived from the literature and optimized to the effluent and filtration modes (dead-end or crossflow). A series of ultrafiltration experiments at laboratory scale are carried out by using chemical mechanical polishing wastewater to optimize and validate the models. Complete dead-end and crossflow ultrafiltration models are developed to simulate the treatment performances of chemical mechanical polishing wastewater under dynamic full-scale and different operating conditions, thus including filtration and washing steps. Simulations show that the dead-end mode is not suitable for chemical mechanical polishing wastewater concentration higher than 100 mgNPs L-1 due to the too fast fouling time and to the high frequency of washing step. The high concentration of chemical mechanical polishing P wastewater (2600 mgNPs L-1) forces industries to use crossflow ultrafiltration to have a profitable process by controlling parameters such as the filtration/backwashing number of cycles, the needed filtering surface and the filtration flux.

15 Décembre 2021 - Study of the energy potential for a water supply network / Soutenance de thèse Gautier HYPOLITE

Abstract : In order to reduce fossil fuels consumption for heating and cooling, different heat sources can be considered. Given theamount of water they carry, water supply systems can play this role and appear to have a high thermal potential. To date, this source has not been used: the main problem is to optimize the sizing of the equipment according to the temporal variability of water flow, water temperature, and the heat (or cold) demand. A first task is to evaluate the available thermal energy. For this purpose, a model based on a minimum number of measurements has been developed. It allows to determine the annual evolution of the temperature and the flow at each point of the network. Temporal variations of water demand and soil surface temperature are taken into account. The ground surface temperature is obtained by satellite measurements. Water flow, soil temperature and water temperature measurements in the network are performed to validate the models and the soil thermal properties. A simulation of the water system hydraulic and thermal behavior is performed for the year 2018 and compared to these measurements. The impact on the water temperature of adding several heat exchanges to the network is then evaluated with this model. In this study, the potential of a raw water system (composed of 5000 km of pipes, and transporting 200 million cubic meters of water per year in the south of France) is studied. As the temperature, the flow rate and heat demand are highly time dependent, a method has been developed to optimize the sizing and location of the exchange systems. This method is based on minimizing the entropy generation in the heat exchanger between the water pipes and the users. The dynamic behavior of a simple heat exchanger (concentric tube) between the network and the user is modeled (pressure profile and fluids and wall temperature calculation). The value of entropy generation due to temperature difference and pressure drop in the exchanger is obtained in transient operation, this value is used as an objective function for the optimization. The results based on the cooling of a data center show that the entropy gain is significant when the optimal size of the heat exchanger is chosen. The use of the raw water network connected to a reversible heat pump for heating and cooling a building has also been studied and results in a high gain compared to an air source heat pump.

Résumé : 

L’optimisation des processus à grande échelle, la réduction des irréversibilités lors des différentes transformations, ainsi que les changements stratégiques majeurs dans le choix des ressources et des applications sont des étapes clés de la transformation du modèle énergétique mondial. En contribuant d’une part à développer des outils d’évaluation théorique de la conversion de la biomasse ce travail fournit des critères permettant d’identifier les limites supérieures théoriques de la conversion de la biomasse. La conversion de deux biomasses (lignocellulosique et microalgue) en alcanes, alcools, monoxyde de carbone ou hydrogène est réalisée. Elle souligne l’importance de la stœchiométrie dans la faisabilité et l’efficacité des conversions. D’autre part ce travail contribue au domaine de l’optimisation des procédés par la réduction des irréversibilités. Le fonctionnement d’un réacteur tubulaire a été étudié en mesurant l’impact de la géométrie. Le procédé de reformage du méthane à la vapeur sert de cas modèle. Une proposition d’équipartition de la production d’entropie à été proposé à partir d’une décomposition en sous réacteurs.
