Technico-economic assessment of groundwater treatment by palladium-on-zeolite-catalyst in comparison to GAC fixed bed adsorbers.
A technico-economic comparison between palladium-on-zeolite (Pd/Y), and granular activated carbon (GAC) based methods of groundwater clean-up is presented. The treatment concepts are assessed by means of process-based cost functions that can be applied to a broad range of case-specific conditions. The analysis accounts for variability in cost and performance parameters and reduces the interplay of multiple factors to expressive indifference curves that can be used for identifying a favorable technology. The findings for the treatment of halogenated hydrocarbons reveal that the Pd/Y offers advantages compared to GAC use in case of high contaminant concentrations and for the treatment of lower halogenated compounds such as cis-Dichloroethene.
