Physicochemical reactions and bacterial adaptation/remanence in treatment processes

The common objective of this theme is to define new processes for water or soil decontamination, by integrating bioproducts (bioflocculants) or reagents naturally present in water (iron) and/or by implementing environmental microorganisms for soil or water decontamination. The processes envisaged are defined to respond to a constrained environment with the absence of heavy investment and reduced maintenance (rustic processes, but which can bring complex physico-chemical mechanisms into play). Reagents are identified and configured from readily available resources and deployed in processes involving physicochemical reactions (sorption, coagulation-flocculation). These processes will be developed in a context of sustainability (low carbon footprint, low energy consumption) and low cost production and/or environmental impact. Microbiological methods are used to develop new strategies to enhance or inhibit microbiological activity for surface, water or soil treatment.
