Abstract
This study was performed to use the packed column flotation process as a
pretreatment of the contaminated dredged sediment in lake, river, or estuaries
for the purpose of reduction of the volume to be treated.
Packed column flotation model was presented to predict the performance of
flotation separation, especially, focusing on removal efficiency of contaminants.
Using packed column flotation model, the effects of principal operating
conditions were investigated on the removal efficiency of contaminants. Air
flowrate, wash water flow rate, and contaminant contents and solids
concentration with a series of attachment rate constants of uncontaminated soil
and contaminants in sediment were selected as the operating p
