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.

    Alternative Energy Potential and Conversion Efficiency of Biomass into Target Biofuels: A Case Study in Ethiopian Sugar Industry- Wonji-Shoa

    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).

    Effect of different wastewater composition on kinetics, capacities, and mechanisms of phosphorus sorption by carbonated bauxite residue

    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.

    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.

28 novembre - 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.

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

Date de soutenance :  mercredi 15 Décembre 2021 à 14:00 (Amphithéâtre du CEREGE / Technopôle de l'Arbois-Méditerranée, BP80, 13545 Aix-en-Provence)

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.
