On-farm biogas scrubber for the simultaneous production of bio-methane and bio-carbon dioxide

The main objective of the EPUROGAZ project is to finalise the development of a biogas purification system for the simultaneous production of bio-CH4 and bio-CO2, economically accessible to the agricultural sector, frugal in its design and operation, and whose industrial mass production will be carried out in France

Hydrodynamics induced by a bubble plume in a column, for different types of bubbles and viscosities of the liquid phase

The objective is to identify the characteristics of the hydrodynamics induced by a plume of bubbles oscillating in a liquid column. The experimental techniques used are optical probing, bubble image taking and processing, and the acquisition of instantaneous velocity fields in the liquid by PIV. The turbulence components induced by the plume are identified by POD. The databases are compared with the NeptuneCFD code.



BiotechnoloGY and pRocEsses for ENergy transition

Le projet BeGreen contribue à la création de nouvelles filières de production de molécules énergétiques par conversion de biomasses (gaz, solides, liquides), ou d’optimiser des voies existantes selon des critères de performances économiques et environnementales. Ce projet vise l’acquisition d’équipements qui ciblent spécifiquement les verrous limitant le développement de ces nouvelles filières depuis le prétraitement des biomasses jusqu’à l’obtention des produits. Les fronts de science concernent



Hydrodynamics of a long isolated bubble in a viscous fluid at rest and in a slightly inclined pipe

The objective is to identify the link between velocity and the shape of long bubbles (called gas pockets), for low pipe inclinations and different liquid viscosities. The experimental techniques used are umbroscopy, 2D2C PIV and TOMOPTV (in collaboration with IMFT within FERMaT). The database is interpreted and simulated with Niceflow.



Biophysics of microalgae flotation

The objective of this project is to develop an innovative flotation process where the bubbles are functionalized with surfactant molecules that are able to form specific bonds with the microalgae cells to be separated. To achieve this objective, atomic force microscopy is used to understand at the molecular level the interactions between the cells and the surfactant molecules, but also between the cells and the bubbles. This new flotation process allows the efficient separation of microalgae without a flocculation step.

Antifouling coatings for the protection of autonomous environmental sensors immersed in continental surface waters

Biofouling is an accumulation of organisms on natural or artificial surfaces, which in most cases leads to major disadvantages. It is also called biofilm in the primary stage. This biofilm, mainly composed of communities of microorganisms, starts with an adsorption of macromolecules (e.g. protein, lipid) as a primary conditioning film.

The objective of the project is to propose anti-adhesive surfaces to combat this problem and to better understand the mechanism of microbial adhesion and test them under hydrodynamic flow conditions.



Role of the pili of Lactococcus lactis in the formation and structuring of a biofilm using a multi-scale biophysical approach

The general objective of the project is to understand the mechanisms involved in the formation, structuring and cohesion of a biofilm of the model lactic bacterium Lactococcus lactis under sheared flow conditions, based on an approach integrating the different relevant scales; from the surface protein to the bacterial population. To understand the role played by pili in biofilm structuring, this project aims more specifically to quantify the interaction mechanisms and mechanical properties of pili at the so-called "Single Molecule" scale by relying in particular on advanced biophysical techniques (optical tweezers and atomic force microscopy).



Better control the morphological properties of aggregates under hydrodynamic constraints

The MORPHING project aims to develop generic tools to advance further in the understanding of aggregation processes within suspensions under controlled hydrodynamic constraints in order to propose innovations for the reactors design and the optimization of the process conditions based on the mastering of the morphological properties of the solid product.



Study of Gas/Liquid Material Transfer in Microstructured Media for the Optimization of Surfactant Management.

The objective of this project is to develop innovative visualisation techniques to quantify the migration, structure and thickness of surfactant layers (TAs) and its impact on gas-liquid oxygen transfer.




Citizen Arenas for improved Ressources management & Environmental quality

The objective of Citizen Arenas for Improved Environmental Quality & Resource use in SMART-ER Cities is to raise citizens’ awareness about environmental challenges and alternative resource management options related to water, biodiversity, waste, air, climate and energy.  Citizen Arenas are an open collaborative forum bringing together citizen and researchers; Enabling co-creation of scientific questions related to air & water quality or energy and waste resources
