Description:
Investigations were carried out to compare and evaluate solidification/stabilization (S/S) processes to treat residues from combustion (MWC). ull factorial experimental design was used to processes to treat bottom ash, air pollution control (APC) residue, The 5 S/S processes included a Portland-cement-only control process the effectiveness of municipal waste evaluate 5 S/S and combined ash. and 4 selected vendor processes. he evaluations included analysis of chemical composition, physical properties, durability, and leaching characteristics. ests used included: moisture content, loss on ignition, bulk density, modified Proctor density, particle size distribution, permeability, specific surface area, porosity, cone penetrometer, unconfined compressive strength, pozzolanic activity, unconfined compressive strength after immersion, wet/dry, freeze/thaw, toxicity characteristic leach procedure (TCLP), availability leach test, distilled water leach test, acid neutralization capacity, and the monolithic leach test. Based on comparison of untreated residues with treated residues, the S/S processes evaluated generally did not decrease the potential for the release of target contaminants. hosphate process did, however, reduce the potential for lead to be released. hether treated or not, the typical release potential for metals was a small fraction of the total metal concentration present in the residues.
