Novel ceramic membrane filters were manufactured from kaolino-illitic clays and calcareous algae (up to 20 wt.%) as porogenic agent. The produced membranes were investigated using X-ray diffraction, thermogravimetric analysis, scanning electron microscope, impedance spectroscopy, and Fourier-transform infrared spectroscopy. All of the filtration su...
La gestion des eaux pluviales à l’aide des ouvrages d’infiltration à la source se généralise. Ces systèmes nécessitent un suivi hydrodynamique pour mieux connaître l’évolution de leurs capacités, adapter leur maintenance et prévenir le colmatage. Un nouveau dispositif d’infiltration est présenté et permet d’obtenir des paramètres représentatifs de ...

Dehydration is a critical step in many food processes. In this paper, we propose an original strategy, basedon experiments and modelling, to evaluate the performance of the compression dewatering of cassava and tohelp design dewatering equipment. The dewatering of various grated cassava roots was experimentally studiedthrough 42 experiments in a fi...
Hydrogels, which are networks of polymer chains in water, are characterized by porous and hydrophilic structures that make them in principle advantageous materials used in the field of filtration. Controlling the transport of solute and particle in such polymer networks can be achieved by controlling their microscopic morphology and porosity. In th...
Aluminum and steel have been the most produced metal and alloy, respectively, for many years. Their extensive use in various industries, their fundamental role in our everyday life, and their excellent recycling characteristics are the major driving forces for development of their production towards more sustainable processes. A successful integrat...
Polystyrene (PS) is a versatile polymer typically used in applications such as yogurt cups, packaging trays, disk cases and toys. To increase recycling rates of PS, dissolution recycling is being investigated, which involves the liquefication of the polymer in a suitable solvent, allowing deep cleaning of the polymer from impurities. Quite specific...
This Master Thesis project is focused on Life Cycle Analysis (LCA) of retrofit solutions for brake emission and the comparison of each solution. Background research was performed to check possible solutions to the Particulate Matter (PM) problem that non-exhaust emissions contribute to. Then four main scenarios were created, based on surface treatm...
We report on a reaction-diffusion model posed on multiple spatial scales that accounts for diffusion, aggregation, fragmentation, and deposition of populations of colloidal particles. The model is able to account for the heterogeneity of the internal porous structure of the layer. For simplicity, we represent the microstructures as discs with presc...
