Membranous Processes Team
Présentation


The EPM team devotes its activities to applied research and its transfer to the industrial world where scientific, economic and confidentiality requirements of the treated subjects interact.
The activities of the team are in strong progression and cover a broad spectrum: from the design of new membranes and modules to the development and installation of new industrial membrane processes. The main objective of the Membrane Processes team is to improve the efficiency of these processes limited by clogging and the cost of implementation, while providing innovative solutions for the treatment of specific effluents and the purification of high value-added compounds.

Any evolution of the processes can only be based on an in-depth knowledge of the problems that generate them and the choices that can be made. The scientific issues raised are complex and multiple. In this context, most of the research activities are carried out in partnership with an industrial company within the framework of a research collaboration contract. Starting from an idea developed in the laboratory or an industrial problem, it is a question here of working in an industrial-EPM partnership in a realistic framework of operating variables. 
The optimization of membrane processes requires a better understanding of the mechanisms involved. The activities of the EPM are divided into 6 interrelated research axes:

    - Membrane bioreactor (Benoit Marrot)
    - Membrane characterization and drinking water (Yvan Wyart)
    - Process Industrialization and CFD (Philippe Moulin)
    - Transport Properties and Metrology (Jean Philippe Bonnet)
    - Effluent treatment (Emilie Carretier)
    - Process Intensification (Mathias Monnot)

    Treatment of Boiler Condensate by Ultrafiltration for Reuse

    The generation of water vapor is crucial for the petrochemical industry. In order to protect the boiler from damage, the re-injected water must not contain any suspended matter, especially hydrocarbons. Moreover, it is condensed steam with a temperature close to 100 °C and the unintentional creation or chronic generation of pollution, respectively, that can more or less produce the concentrated pollution. In this context, membrane processes appear promising in order to achieve this reuse and more especially crossflow ceramic membranes. The novelty of this paper is to study the retention of hydrocarbons and suspended solids contained in the condensate hot water of a high-capacity boiler using ceramic ultrafiltration membranes. In total, two ultrafiltration molecular weight cut-offs were used: 50–150 kDa. Several operating parameters were studied such as effluent type (accidental or chronic pollution), temperature, transmembrane pressure, initial volume, and pilot plant size. In all cases, retention of suspended matter was above 90% and residual hydrocarbon concentrations were under 0.1 ppm even for high-volume concentrations. Control of the transmembrane pressure and the molecular weight cut-off of the membrane are key to optimizing the process. Despite the high-volume concentration obtained, the membranes were perfectly regenerated with conventional cleaning procedures.

    Membrane Separation Used as Treatment of Alkaline Wastewater from a Maritime Scrubber Unit

    Since 1 January 2020, the sulfur content allowed in exhaust gas plume generated by marine vessels decreased to 0.5% m/m. To be compliant, a hybrid scrubber was installed on-board, working in closed loop and generating a high volume of alkaline wastewater. The alkaline water suspension was treated by a silicon carbide multitubular membrane to remove pollutants, and to allow the water discharge into the natural environment. In this paper, membrane filtration behavior was analyzed for the maritime scrubber wastewater. A range of operating parameters were obtained for several feedwater quality-respecting industrial constraints. The objective was an improvement of (I) the water recovery rate, (II) the filtration duration, and (III) the permeate quality. Thus, in high-fouling water, a low permeate flow (60 L h−1 m−2) with frequent backflushing (every 20 min) was used to maintain membrane performance over time. In terms of water quality, the suspended solids and heavy metals were retained at more than 99% and 90%, respectively. Other seawater discharge criteria in terms of suspended solids concentration, pH, and polyaromatic hydrocarbons were validated. The recommended operating conditions from laboratory study at semi-industrial scale were then implemented on a vessel in real navigation conditions with results in agreement with expectations.

    Membrane characterisation from the support to the skin layer: Application to silicon carbide (SiC) membranes

    SiC membranes are used in many industrial fields with high performances and good retention efficiency in the filtration of loaded liquids such as wastewater, oil or wine. Technologies allow to characterise membrane’s surface but few allow the characterisation of its depth. This paper proposes the combination of results obtained by the usual techniques of porous materials and by 3D X-ray tomography characterisation. A morphological analysis of solid and porous phase is carried out on the total thickness of the membrane. Combination of results on all layers is relevant for the study of SiC membranes, showing not only the SiC surface properties but also the 3D description of the porous material (i.e. support, layer and skin). The definition of essential parameters to define the efficiency of a filtration such as hydrophobicity, porosity and tortuosity allows to justify the use and superior performance of SiC membranes for the filtration of loaded liquids.

    Retention of the Tulane virus, a norovirus surrogate, by ultrafiltration in seawater and production systems

    Shellfish as a foodstuff must meet sanitary quality objectives for the protection of consumers and this quality is closely linked to the water. The oyster industry considered this challenge related to contaminations and currently, the major risk of disease is due to the presence of norovirus (NoV) since all oyster-consuming countries report outbreaks of gastroenteritis linked to the presence of this microorganism. Ultrafiltration has already demonstrated to be efficient for viral protection of oyster farms in previous studies. In this work, retention by ultrafiltration of Tulane virus, a NoV surrogate, was evaluated. The effect of virus concentration in the feed on the ultrafiltration efficiency has been assessed. Low retentions of about 1 log were observed at the lowest viral concentrations. At higher concentrations, an increase of retention up to 5 log was obtained. These results highlight the potential overestimation of UF efficiency during laboratory experiments realized at high concentrations, compared to low concentrations found in environmental resources. In agreement with other studies, higher retentions at high concentrations could be explained by formation of viral aggregates, which could facilitate the steric exclusion but also modify the electrostatic and hydrophobic interactions between isolated viruses/aggregates and membrane. Virus retentions with a fresh mineral water (Evian water) and seawater were compared. Seawater achieved higher retention rates for Tulane virus due to the membrane fouling.

13 décembre - Développement d’une unité hybride couplant la désulfuration des gaz d’échappement et le traitement des effluents aqueux pour la marine marchande / Soutenance de thèse Maryse DROUIN
Doctorante : Maryse DROUIN

Date : Mardi 13 décembre à 9h45 dans l’amphithéâtre du CEREGE (Technopole Environnement Arbois - Méditerranée)

Résumé : Suite à la réduction des émissions de composés soufrés en pleine mer de 85 %, des unités de traitement de gaz d’échappement hybrides ont été installées sur les navires de commerce. Ces unités combinent le traitement du gaz par absorption et l’épuration des effluents liquides par filtration membranaire. La mise en place de ces procédés embarqués est récente (2020) et les contraintes d’opérabilités sont nombreuses notamment en ce qui concerne le fonctionnement des unités membranaires. Dans ce contexte, la thèse a pour principaux objectifs : (i) d’étudier le transfert de matière au travers des membranes (ii) d’optimiser les conditions opératoires et la gestion des procédés afin de (iii) fiabiliser le couplage des procédés en vue d’une utilisation continue. Pour cela, une caractérisation des différentes qualités d’eau à traiter obtenue après le lavage des gaz d’échappement a été réalisée. Puis le comportement et les performances des membranes multitubulaires, en carbure de silicium (SiC) et en oxyde de zircone (ZrO2), ont été étudiés à l’échelle semi-industrielle pour la filtration d’effluents réels. Les résultats obtenus ont permis pour chaque membrane de préconiser des paramètres de fonctionnement stable et de simplifier la gestion des unités embarquées. Les paramètres recommandés pour les membranes SiC, ont été validés en conditions réelles sur l’un des navires au cours de la navigation. Lors de cette étude, les résultats ont également mis en avant mettant une robustesse et une flexibilité de l’unité membranaire vis-à-vis du procédé global de désulfuration. Le traitement des eaux permet une navigation plus respectueuse de l’environnement avec la production d’un perméat exempt de matières en suspension et moins concentré en ions métalliques et en hydrocarbures. De plus, les paramètres préconisés ont permis une réduction de 70 % du volume de concentrat, dont le stockage est aujourd’hui la principale limitation à l’utilisation continue des unités en Closed Loop.

Abstract : Water reuse is a sustainable development strategy that benefits society and future generations. In this study, a semi-industrial ultrafiltration (UF) pilot plant established at the outlet of a wastewater treatment plant was studied to assess its feasibility and sustainability for non-potable water reuse. The optimization of operating conditions made it possible to support reliable and sustainable filtration performance, the operating conditions were optimized through comparative analysis in terms of water quality, permeability variation, irreversible fouling management, and water recovery rate. The best conditions were J80t40BW1/3 (flux of 80 L·h−1·m−2, filtration cycle time of 40 min, 1 air backwash followed by 3 classical backwashes), J60t60BW1/4 and J60t60BW1/3. The long-term study on condition J60t60BW1/3 provides sustainable and adaptable filtration performance regardless of the temperature and feed water quality variation. In addition, the air backwashes enabled excellent reversibility of membrane fouling, which was approximately 1.25 to 2 times higher than of classic backwashes in average. The quality of the UF permeate was good enough to be reused in non-potable purposes as it met reuse guidelines of the World Health Organization, reuse standards of France, and the most recent EU regulation for agricultural irrigation. A specific study of membrane cleaning has shown that the addition of NaClO in backwash water can greatly increase cleaning efficiency of air backwashes. Finally, the calculation of the capital expenditure (CAPEX) and operational expenditure (OPEX) of the UF system under optimized conditions gives a profitable net unit price for water production. Through this thesis, UF is confirmed to be a reliable tertiary treatment for water reuse and the results give operational indications for the industrial scale and provides proposals for the management of membrane fouling by air backwash with chemical assistance.
