Bacterial biofilm supported on granular activated carbon and on natural zeolites- an application to wastewater treatment
Lameiras, Sandra Raquel de Vasconcelos
Tavares, M. T.
The removal of many heavy metals from industrial wastewater is one of the most
important environmental problems to be solved today. The retention of this contaminants by a biofilm supported on granular activated carbon or on natural zeolites is one of the promising
technologies for the reduction of this problem, because it is cheap and it removes a broad range of substances, heavy metals and organic compounds.
This study aims the development of a system of two mini-columns in series for the
removal of chromium (VI) using a biofilm of Arthrobacter viscosus supported on two
different materials: granular activated carbon and natural zeolite. The effect of the
regeneration of granular activated carbon was also studied.
