| Summary: | This Final Year Project is a study of Solidification/Stabilization of activated waste sludge from
Petronas Penapisan Melaka Sdn. Bhd, PPMSB. Three cementitious materials were used to
investigate solidifYing and stabilizing the hazardous wastes containing heavy metals. The
cementitious materials were Pulverized Fuel Ash (PFA), Ground Granulated Blast Slag (GGBS)
and Lime. These materials will be the cement replacement of Ordinary Portland Cement (OPC).
The project focused on the strength development and leaching rate of zinc and lead ion of the
product. The strength was tested using Unconfined Compressive Stress (UCS) and leaching by
Toxicity Characteristic Leaching Procedure (TCLP) and Atomic Adsorption Spectrometer
(AAS). Usage ofPFA and Lime gives significant value for strength development and leaching
rate than GGBS. The concrete strength is up to 30 Mpa and percentage of immobilizing the zinc
ion up to 94% and lead ion to 100%. Performance between PFA and Lime is about the same in
terms of strength and leaching rate. Improvement shall be made in finding the most effective
ratio of each binder. Combination of binders also shall be done to produce effective combination
of SIS process for PPMSB sludge. |
