Approche intégrée du traitement et de la valorisation des eaux et des déchets
Les recherches de l’équipe Traitement des Eaux et Déchets (TED) sont
organisées autour d’une vision globale intégrée du traitement et de la
valorisation des eaux usées, des biomasses et des déchets.
Cette approche systémique s’appuie sur une démarche conjointe
expérimentation-modélisation-simulation des procédés, pour traiter,
réutiliser et valoriser des effluents urbains ou industriels et des
biomasses (production d’H2, de CH4, de chaleur ; production de
biocarburants et de molécules plateformes pour la chimie ; récupération
des nutriments, des métaux, etc.). Elle vise à contribuer aux grands
enjeux du 21ème siècle et plus particulièrement aux transitions
écologique et énergétique.
A cet effet, l’équipe développe des approches multi-échelles de
traitement et de valorisation des effluents et des biomasses. Aux
échelles moléculaire et cellulaire, l’équipe possède et développe des
compétences pour les caractérisations spécifiques comme la rhéologie et
la (bio)-calorimétrie. Cette dernière est appliquée à la fois à la
détermination de la chaleur liée au métabolisme cellulaire et aussi à la
calorimétrie haute pression (max 300°C, 60 MPa), l’originalité de
l’équipe porte sur le design de cellules calorimétriques spécifiques. A
l’échelle du réacteur, les études se focalisent sur le développement, le
dimensionnement et l’optimisation de procédés biologiques,
thermochimiques et physico-chimiques. La caractérisation des grandeurs
cinétiques et de transferts mène au développement de modèles dédiés. Ces
modèles sont utilisés au sein de méthodologies intégratives spécifiques
dès que deux ou plusieurs procédés sont couplés. Ces méthodes sont
développées pour déterminer le fonctionnement optimal du couplage et/ou
du site industriel accueillant ces procédés.
Les thématiques développées dans l’équipe TED s’articulent autour des trois axes suivants :

déchets ainsi qu’à la compréhension des mécanismes de transfert et
processus réactionnels mis en jeu.

The hydrogen-based economy will require not only sustainable hydrogen production but also sensitive and cheap hydrogen sensors. Commercially available H2 sensors are limited by either use of noble metals or elevated temperatures. In nature, hydrogenase enzymes present high affinity and selectivity for hydrogen, while being able to operate in mild conditions. This study aims at evaluating the performance of an electrochemical sensor based on carbon nanomaterials with immobilised hydrogenase from the hyperthermophilic bacterium Aquifex aeolicus for H2 detection. The effect of various parameters, including the surface chemistry, dispersion degree and amount of deposited carbon nanotubes, enzyme concentration, temperature and pH on the H2 oxidation are investigated. Although the highest catalytic response is obtained at a temperature around 60 °C, a noticeable current can be obtained at room temperature with a low amount of protein less than 1 µM. An original pulse-strategy to ensure H2 diffusion to the bioelectrode allows to reach H2 sensitivity of 4 µA cm-2 per % H2 and a linear range between 1-20 %. Sustainable hydrogen was then produced through dark fermentation performed by a synthetic bacterial consortium in an up-flow anaerobic packed-bed bioreactor. Thanks to the outstanding properties of the A. aeolicus hydrogenase, the biosensor was demonstrated to be quite insensitive to CO2 and H2S produced as the main co-products of the bioreactor. Finally, the bioelectrode was used for the in situ measurement of H2 produced in the bioreactor in steady-state.

This study aims at evaluating the effect of different wastewater composition on kinetics, capacities, and mechanisms of P sorption by carbonated bauxite residues (CBR). A series of batch experiments was performed to investigate P sorption behaviors from solutions prepared with different aqueous matrices (deionized water, tap water, and real wastewater) and different initial P concentrations (from 10 to 200 mg P/L). Also, a series of sequential P extractions was performed to investigate P fractionation of CBR before and after its use in P sorption experiments, and hence to elucidate the main P removal mechanisms. The results indicate that initial P concentration is the most influential parameter controlling kinetics, capacities, and mechanisms of P removal in batch experiments. Kinetic constant of P sorption increases exponentially with decreasing initial P concentration below 100 mg P/L, thus indicating a faster achievement of P sorption equilibrium. Equilibrium P sorption capacities increase linearly from about 0.2 to about 3.9 mg P/g CBR with increasing initial P concentration from 10 to 200 mg P/L, thus indicating that P saturation of CBR was not reached. Ca phosphate precipitation is the main P removal mechanism at higher initial P concentrations (> 10 mg P/L), whereas phosphate adsorption on CBR surface becomes more relevant over the total amount of P removed at lower initial P concentrations. Overall, the findings of this study allow to evaluate kinetic constants, sorption capacities, and removal mechanisms under different operating scenarios, thus providing crucial information for the design and operation of P treatment units.

Global energy security relies on fossil-based resources that are affiliated with the source of global warming, apart from punches of political and economic instabilities. Biomass is a promising alternative carbonaceous feedstock used for the production of clean energy that could have the potential to substitute for fossil fuels. This study aims to present a conceptual design that considers the criteria to identify the upper theoretical limits of biomass conversion, thus providing the potential approach to the conversion of three biomass (by-products: dry molasses, dry bagasse, and dry filter cake) through gasification, in order to contribute the biomass carbon-capturing by the model assessment of stoichiometric mass conversion and energy efficiency indicators into simple thermodynamic energy vectors, such as alcohols, alkanes, and syngas (a mixture of carbon monoxide and hydrogen). Modeling plays up the importance of stoichiometric efficiency of biomass conversion with the supply of oxygen and hydrogen. This realizes that the multi-product diversification of feedstock into syngas, hydrocarbons, and alcohol through integrated process schemes could have the potential to fill the energy gap and help to manage environmental load. In regard to biomass conversion results, the mass conversion and energy conversion efficiencies of dry bagasse have better conversion potential than molasses and F. cake (% mass conversion = 129 in syngas, 54.4 in alkane, and 43.4 in alcohol; % energy conversion = 94.3 in syngas and 93.3 in alkane and alcohol).

We analyze the integration of intermittent renewables-based technologies into an electricity mix comprising of conventional energy. Intermittency is modeled by a contingent electricity market and we introduce demand-side flexibility through the retailing structure. Retailers propose diversified electricity contracts at different prices, but in an insufficient number to cover intermittent production. These delivery contracts are modeled similarly to numeraire assets. We study the competitive equilibrium of the state-contingent wholesale electricity markets and the delivery contract markets. We also provide an analysis linking the delivery contracts to social welfare. Finally, we discuss the conditions under which changing the delivery contracts improve penetration of renewables and increases welfare. These provide useful insights for managing intermittency and achieving renewable capacity objectives.

- Sustainable biorefinery schemes for the recovery of energy, material and nutrient of residual biomass / Soutenance de thèse Monica AMADO
Doctorant : Monica AMADO
Date : lundi 28 novembre à 9h30 dans La salle 205 du CEREGE / Arbois
Abstract : Agricultural activities are a constant source of residual biomass that does not usually have an added value during harvesting activities or throughout the raw material transformation industry, impacting the environmental surroundings where these activities take place. The residual biomass coming from the livestock sector (manure) and the agricultural sector (transient and permanent crops) has a high pollutant load related to biodegradable organic matter.
The problem of the project focuses on Colombian economic changes that have encouraged the use of biofuels as an alternative to reduce dependence on the fossil fuel industry. By presenting the biological processes of anaerobic co-digestion (AD) or dark fermentation (DF) as an alternative for the waste valorization of three relevant agricultural waste from the Colombian (coffee mucilage, cocoa mucilage and swine manure) due to its production increase and their high content of carbohydrates, proteins, and cellulose.
Bioprocesses are limited by efficient and optimal design. Therefore, the results present three biorefinery schemes modeled in Aspen Plus, for the recovery of products and by-product. Furthermore, through energy, by using Aspen Energy Analyzer and life cycle assessments (LCA - SimaPro), the project presents the sustainability and efficiency for the proposed schemes.
The project aims an advance in the subject given that the first works in the country have been conceptual approaches to develop the biorefinery concept.

- Study of the energy potential for a water supply network / Soutenance de thèse Gautier HYPOLITE
Doctorant : 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.
