Effect of conditioning for Pb (II) and Hg (II) biosorption on waste activated sludge
This study focuses on adsorption of Pb (II) and Hg (II) on nonviable activated sludge
biomass at both batch and continuous-flow operational conditions. The raw biomass was
supplied from a nearby municipal wastewater treatment plant activated sludge aeration unit.
First, optimum pHs for Pb (II) and Hg (II) adsorption was investigated on raw biomass.
Optimum pH for Pb (II) and Hg (II) were found to be 3.5 and 5.8, respectively. Successively
raw biomass was conditioned by 12 different methods and the method yielding highest …
