Abstract
The soil aquifer treatment (SAT) is one of the effective method in the removal of heavy metals from leachate.
In this study gravelly soil was used alone and in conjunction with saw dust and groundnut Shell as an
adsorbent. The removal efficiencies of three heavy metals namely Arsenic, Cadmium and Nickel were
observed. The discharge or flow rate of leachate through soil column has direct influence on the removal of
heavy metals. Lower flow rate showed higher removal efficiencies of heavy metals. Higher removal
efficiencies were observed in the gravelly soil in conjunction with groundnut shell than gravelly alone and in
conjunction with saw dust.
Keywords:
leachate, heavy metal, flow rate, removal efficiency, saw dust, groundnut shell
