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.

    Villermaux–Dushman Test of Micromixing Characterization Revisited: Kinetic Effects of Acid Choice and Ionic Strength

    The well-known Villermaux-Dushman system is nowadays widely used for examining the micromixing efficiency either in batch or continuous intensified reactors. However, a bibliographic review shows that kinetic data are too scattered for a reliable determination of the micromixing times. The Dushman reaction kinetics is then reexamined with the use of sulfuric and perchloric acids. The results confirm the fifth-order rate law. More precisely, the I-, H+, and IO3- dependence orders on the rate law are, respectively, 2, 2, and 1, under any condition. To be more consistent with the reactant concentrations used in the Villermaux-Dushman test, we extend their studied range, namely, 1.6 x 10(-3) M <= [I-](0) <= 1.6 x 10(-2) M, 1.2 x 10(-4) M <= [H+](0) <= 1.57 x 10(-2) M, and 4 x 10(-5) M <= [IO3-] <= 2.1 X 10(-4) M. The ionic strength varies up to 2 M. The experimental results show that the rate constant is still ionic-strength-dependent. The results obtained with sulfuric and perchloric acids are found to be consistent and in relatively good agreement at small ionic strengths (mu < 0.1 M) only. At a higher ionic strength, the use of sulfuric acid requires sustained attention to the constant of the second dissociation equilibrium. The nonideal solution behavior raising at a high ionic strength makes its estimation deeply sensitive.

    Application of Moving Bed Biofilm Reactor and Fixed Bed Hybrid Biological Reactor for Oilfield Produced Water Treatment: Influence of Total Dissolved Solids Concentration

    This experimental paper deals with the development of a hybrid biological reactor for the treatment of a synthetic oilfield produced water under an increase in total dissolved solids (TDS) concentration. To comply with strengthening regulations concerning produced water discharge and peculiar produced water compositions, a moving bed biofilm reactor (MBBR) consisting in a combination of free activated sludge and moving biofilm supports was compared to a fixed bed hybrid biological reactor (FBHBR) consisting in a combination of free activated sludge and a fixed biofilm support. After a 216 days experimental period, the MBBR and the FBHBR were efficient to treat a synthetic produced water with chemical oxygen demand (COD) removal rate above 90% under an increase in TDS concentrations from 1.5 to 8 g·L−1. Ecotoxicity measurements on freshwater and marine microorganisms revealed an absence of toxicity on treated waters. A decrease in bacterial diversity indices with respect to the inoculum was observed in both bioreactors. This suggests that the increase in TDS concentrations caused the predominance of a low number of bacterial species.

    Industrial symbiosis profiles in energy-intensive industries: Sectoral insights from open databases

    Process industries are the foundation of the European economy, transforming raw materials into building blocks for strategic products and applications in today's society. Such industries range from steel, cement, or minerals to chemicals such as lubricants for wind turbines and polymers that prevent waste in logistic supply chains. The downside of this foundation industry is its high environmental impact regarding emissions, and intensive use of energy and resources. One of the key strategies to address such challenges is industrial symbiosis: various industries establish collective efforts to find value while transitioning to a more circular economy. This paper presents an exploratory analysis of databases on IS case studies. We used the European standard classification for economic activities (NACE) to draw industrial sector profiles for the most relevant energy-intensive industries: chemicals, steel, and cement, coupled with urban synergies. The majority of the synergies includes the chemicals sector with most commonly shared streams being energy, water, and carbon dioxide. IS cases are ranked in terms of frequency, then classified in topical groups and finally, the sustainability impact of the different categories is discussed. The outcome is a methodology to frame and assess industrial symbiosis case collections useful for future exploring and exploiting circularity projects in public and private organisations.

    Dynamic modeling of water temperature and flow in large water system

    Thermal energy counts for a large part of the total energy consumption. To reduce fossil fuel consumption for heat and cold generation, different low temperature heat sources have been considered. Water networks have been considered as a large amount of water flow through it. To measure the thermal potential of the system, this paper provides a method in unsteady state to determine water temperature and flow in large water systems made of buried pipes. The model has been applied to a raw water supply system made up of 5000 km of piping and carrying 200 million m3 annually situated in the south of France. Water temperature is calculated considering heat exchange and the spatial specificities of the network (diameter of the pipes, depth, type of soil ...). Soil and water temperature measurements have been made to validate the model values. The model can predict water flow and temperature according to time with good accuracy: maximal error of 10% on the flow is obtained, the root mean square error on the calculated temperature is 0.84 circle C, and the correlation coefficient between the calculated and the measured temperature values is 0.98. The impact of adding several heat (or cold) injections in the system has been evaluated with the model. After a 2 MW heat exchange, the water temperature is increased by at least 1circC for 10 km downstream the exchange.

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.
