Abstract(s)The release of heavy metals in aquatic ecosystems is a matter of great concern due to their toxicity and accumulation in biota. Bottom sediments can act as sink of these pollutants. Several remediation technologies have been applied in order to treat wastewater and contaminated sediments. In this study, a permeable bio-barrier composed by low cost biomaterials was tested for water treatment and sediment protection against metal adsorption. The novelty of this work entails the combination of bacterial biosorption properties with the adsorption capacity of a natural clay. The results of preliminary continuous column experiments reveal the ability of vermiculite to entrap Cu ions, and highlight that metal adsorption can be enhanced by the presence of a Pseudomonas putida biofilm attached to the vermiculite surface.
