Abstract(s)The removal of heavy metals linked to organic compounds like phenol, chlorophenol, and o- cresol, is one of the most important environmental problems yet to be solved. The retention of these contaminants by a biofilm supported on granular activated carbon is a promising technology for the treatment of diluted solutions, as the biofilm is able to retain the metallic ions and the support will help to fix them for further catalytic applications. The addition of three different organic compounds, i.e., phenol, o-cresol, and chlorophenol, to the metallic solution was studied to better describe the real industrial effluent. A modeling approach for an expanded bed biosorption system was presented using the ADR (Advection-Dispersion Reaction) equation as the basis of the mathematical description. Several biosorption studies were made using a bacterial biofilm of Arthrobacter viscous supported on pre-treated granular activated carbon in a mini-column arrangement and the obtained data were compared with the predicted by the model. The initial chromium (VI) and organic compound concentration ranged from 10 to 100 mg/L. This is an abstract of a paper presented at the 7th World Congress of Chemical Engineering (Glasgow, Scotland 7/10-14/2005).
