1 Removal of Heavy Metals from Rainwater in Batch Reactors with Sulphate Reducing Bacteria (SRB)

Authors: Abdulsalam I. Rafida

Abstract:

The main objective of this research was to investigate the biosorption capacity for biofilms of sulphate reducing bacteria (SRB) to remove heavy metals, such as Zn, Pb and Cd from rainwater using laboratory-scale reactors containing mixed support media. Evidence showed that biosorption had contributed to removal of heavy metals including Zn, Pb and Cd in presence of SRB and SRB were also found in the aqueous samples from reactors. However, the SRB and specific families (Desulfobacteriaceae and Desulfovibrionaceae) were found mainly in the biomass samples taken from all reactors at the end of the experiment. EDX-analysis of reactor solids at end of experiment showed that heavy metals Zn, Pb and Cd had also accumulated in these precipitates.
