Presentation
Research conducted under the theme Reagent Transfer, rheology and environmental processes includes three items:
- The dynamics of hydro-systems;
- Environmental process engineering;
- The rheology of complex fluids.
Modeling of the mechanisms of action of contaminants in hydro-systems
Modeling of the action mechanisms of contaminants within hydro-systems is a response to Directive 2000/60 / EC, or "Water Framework Directive" defining a community water management and protection policy. Its Article 16 specifies that actions must be taken "against the water pollution by certain pollutants or groups of pollutants presenting a significant risk to or via the aquatic environment, in particular the risks to which the waters are used as drinking water ".
In this context, one of our objectives is to optimize the processes of depollution of urban effluents (domestic and rainfed). The decontamination structures we are studying range from the so-called conventional systems to alternative techniques consisting essentially on rustic processes.
The technical and scientific locks are, on the one hand, the phenomenological understanding of the biotic and abiotic processes within the hydro-systems and on the other hand, the understanding of the nature of the contaminants. The fate of heavy metals and polycyclic aromatic hydrocarbons resulting from urban discharges in rainy weather is one of the focal points of research carried out at the Ostwaldergraben field experimental site. Similarly, we are interested in the identification and quantification of pharmaceutical residues whose induced stresses on fauna and flora are still poorly known.
