In Hong Kong, with the implementation of the Strategic Sewage Disposal Strategy (SSDS), there will be a substantial increase in the generation of sewage sludge. An alternative method using pulverized fuel ash (PFA) generated from a local coal fire power station and lime to stabilize the sludge for potential beneficial uses is studied. The effects of the stabilizing agents on the leaching of heavy metals and pasturing of coliform are studied. The results show that PFA together with a small percentage of lime addition has the potential to reduce heavy metal leaching and reduce the total coliform content of the stabilized sewage sludge.
