Streszczenie

Sewage sludge incineration may have adverse impact on the environment due to heavy metals toxicity. Heavy metals concentrations in sewage sludge ash increased in comparison to concentrations in sewage sludge. The aim of the study is to evaluate the impact of temperature and time incineration on the transfer coefficient of heavy metals from the sewage sludge into the sewage sludge ash. The transfer coefficient range from a minimum of 0.0 for lead and cadmium to a maximum of 3.5 for zinc. The study shows that the transfer coefficient of heavy metals mainly depend on the incineration temperature.
