The aim of this paper is to examine the possibilities of solidification of sludge from physico-chemical treatment and recovery with the use of commercial sorbents and cement. For proposal of solidification formulas cement, fly ash and two commercial available types of sorbents on different bases were selected. These formulas were then subjected to laboratory testing with the aim to find the most suitable composition for this type of waste sludge solidification. The paper describes achieved results.

Accepted Practice

Municipal waste combustion typically involves both energy recovery as well as volume reduction of municipal solid waste prior to landfilling. However, due to environmental concerns, municipal waste combustion (MWC) has not been a widely accepted practice. A primary concern is the leaching behavior of MWC ash when it is stored in a landfill. The ash consists of a finely divided fly ash fraction (10% by volume) and a coarser bottom ash (90% by volume). Typically, MWC fly ash fails tests used to evaluate leaching behavior due to high amounts of soluble lead and cadmium species. The focus of this study was to identify specific lead bearing phases in MWC fly ash. Detailed information regarding lead speciation is necessary to completely understand the leaching behavior of MWC ash.
