[ES] En este trabajo se elaboró un material vitrocerámico conteniendo la fase de hidroxiapatita, partiendo de residuos industriales y urbanos. Sobre la superficie del material se desarrollaron biopelículas de los microorganismos que aparecen habitualmente en las aguas residuales. Se hicieron ensayos de retención usando distintos metales pesados para evaluar la capacidad del material de eliminar tales elementos de un medio acuoso en presencia y ausencia de la biopelícula. Los resultados ponen de manifiesto la participación microbiana en los procesos de eliminación de los metales pesados del medio acuoso y ofrecen la posibilidad de utilizar el material vitrocerámico en un proceso de biorremediación de aguas contaminadas por metales pesados.
[EN] In this study, a glassceramic material with hydroxyapatite phase was manufactured from industrial and urban wastes. On this material, biofilms from the microorganisms usually appearing in wastewater were developed. Batch assays were made using different heavy metals to analyze glassceramic material capacity to retain these elements from an aqueous medium in biofilm presence and absence. The results suggest that microorganisms are implicated in the removing of heavy metals from the aqueous medium and open the possibility to use the glassceramic material in a bioremediation process.
