Technique for the remediation of polluted steelworks sites
The main goal of the project has been to develop a methodology for selecting the most appropriate remediation technologies for polluted steelworks sites. The ability to remediate polluted land successfully and cost effectively depends mainly on the construction of an accurate conceptual model, capable of quantifying the impact of contaminants on soil quality both before and after remediation. As such, an essential part of this research was to tailor the use of site characterisation techniques to polluted steelworks sites for setting up and calibrating a mathematical model. Through the characterisation of soil samples taken from three different industrial plants (Sidenor, Corus and Vitkovice), the effect of steelworks activities on selected sites has been quantified. The reduction of this impact has been demonstrated by using appropriate treatments (soil washing, thermal treatment and bioremediation). Soil samples were treated at laboratory and pilot scale to determine main process parameters and remediation effectiveness. The technologies applied were evaluated in terms of pollutant-removal efficiency, toxicity reduction and sustained costs. A system has been developed which forecasts the fate of environmental pollutants on steelworks sites. The parameter of pollutant concentration in steelworks sites was incorporated within a conceptual model developed from non-invasive and invasive site investigation studies. Moreover, leaching tests have been performed to study the ability of pollutants to migrate and impact on neighbouring environmental receptors (both before and after remediation treatment). The conceptual model has been translated into a mathematical model and the fate of the pollutants predicted. The results of experimental trials have been used to validate the mathematical model.
