International cooperations

Cooperation with African countries

The MERE project-team is very actively involved in cooperation with Africa in different but related ways.

Cooperation with Latin America

The MERE project-team interacts with researchers of CMM (Centro de Modelamiento Matematico, UMR CNRS Santiago de Chile) thanks to the INRIA-Conycit project 'ECOLOMICRO' (2006-2008), on estimation of unknown inputs (with G. Acuna, University of Santiago) and optimal impulsive control for fed-batch reactors [Oops!] (with P. Gajardo, Chilean project leader, University of Valparaiso, and H. Ramirez, University of Chile). The copper industry in Chile produces contaminated water, that can be depolluted by well-selected bacteria.

Cooperation with North America

The MERE project-team interacts with researchers of the Department of Mathematics of the Louisiana State University in Baton Rouge in the framework of the NSF/DMS Grants 0424011 and 0708084. In particular, in collaboration with M. Malisoff and M.S. de Queiroz, papers have been written in the past few years (four journal papers this year). F. Mazenc delivered a lecture in the "Workshop on Control Theory and Mathematical Biology" organized by Michael Malisoff (July 2007) LSU, Baton Rouge.

The TREASURE network

Within the INRIA program “EuroMéditerranée”, the team received since 2006 the financial support for the constitution of a “trans- Méditerranée” research network . “Membranes reactors” has been chosen as the main theme of the research program. After two initial meetings in Milano (Italy) and Tlemcen (Algeria), the network has been officially launched at Nice in October 2007 the 26th, under the acronym


Treatment and Sustainable Reuse of Effluents

in Semi-arid Climates

The following teams belong to the network

The Scientific objectives are the following. Nowadays, the drastic economical constraints of waste-water treatments lead the main actors to consider more and more often the biological depollution. The principle consists in the transformation in solid of liquid organic matter produced by the main bio-geochemical cycles (of carbon or nitrogen), with the help of micro-organisms (that constitutes the so-called “biomass”). As far as waster-water treatment is concerned, the principle can be synthesized in two steps. First, in adequate environmental conditions of pH, temperature, presence of oxygen,..., polluted liquids and biodegradable solids are transformed into biomass and gas by the micro-organisms. In a second stage, liquid and solid phases are separated in order to reject the purified liquid phase only. It should be noticed that such a process acts as a concentrator of pollution into biomass, and that the smallest biomass production is a main research objective. The network will focus on the following main directions.

Contribution to fundamental and applied research on the subject is the first objective. The second one is to contribute to the share of knowledge between members of the network and help its diffusion all over Mediterranean countries.
