Lead adsorption in a serpentine millichannel-based packed-bed device:
Effect of hydrodynamics and mixing characteristics
Abstract
The present study depicts the hydrodynamics along with the mixing
characteristics inside a millichannel-based serpentine fixed-bed device
to attain the particular demands of the fabrication of the miniature
adsorption devices. Residence Time Distribution (RTD) analyses were
accomplished to analyze the velocity distribution inside the packed bed
geometry. The operating variables effect the hydrodynamics, mixing, and
the lead adsorption characteristics, which were pronounced clearly in
the present context. Depending on the results obtained in the
experiment, the new correlations were proposed. The parametric effects
on the lead ions adsorption were studied in the same millichannel
geometry packed with the graphene oxide (GO) coated glass beads. Thomas
model was utilized to investigate the kinetics of the adsorptive removal
process. The regeneration study of the said millichannel-based fixed-bed
device was also executed.
