BACTERIAL BIOFILM SUPPORTED ON GRANULAR ACTIVATED CARBON-AN APPLICATION TO WASTEWATER TREATMENT

摘要

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 is one of the promissing tecnologies for the redution of this problem, because it is cheap and it removes a broad range of substances, heavy metals and organic compounds. In this study we have two different kinds of granular activated carbon: one treated with HNO_3 and other treated with H_2O_2. Preliminary studies realized by this group showed that Artherobacter viscosus present good characteristics to be applied to a biosorption system.
