Removal of copper ions from contaminated groundwater using waste foundry sand as permeable reactive barrier
Faisal, A. A. H. & Ahmed, M. D.
Abstract
Computer solutions Multiphysics 3.5a software
was used for simulating the two-dimensional copper
migration including sorption process through the saturated
zone of the soil in the presence of permeable reactive
barrier for equilibrium condition. The 1:3 mixture of waste
foundry sand and Kerbala’s sand was used as filling
material for this barrier. The waste foundry sand was represented
the reactivity material, while Kerbala’s sand used
to increase the permeability of reactive barrier only.
However, Fourier transform infrared analysis proved that
the carboxylic and alkyl halide groups are responsible for
the sorption of copper onto waste foundry sand. Batch tests
have been performed to characterize the equilibrium
sorption properties of the waste foundry sand and Kerbala’s
sand mix in copper-containing aqueous solutions. Numerical
and experimental results proved that the permeable
reactive barrier plays a potential role in the restriction of
the contaminant plume migration. Also, predicted results
showed that the thicker barrier is better than the thinner
ones in copper treatment, and this barrier saturates with
contaminant as a function of the travel time. However, a
good agreement between the predicted and experimental
results was recognized with mean error not exceeded 10 %.
