Status of Thermal Soil Remediation

Thermal Soil Remediation can when implemented correctly achieve very strict clean-up criteria. Every site has its own challenges and a serious and thorough approach is necessary to deliver robust and predictable results. This presentation goes through the key mechanisms of thermal soil remediation and highlights important parameters to identify. Conceptual site model, design considerations, heat transfer modelling, sensitivity analysis is all important aspects of thermal soil remediation. Case studies will be presented to show the variety of sites (from sand to granite) and contaminants (chlorinated solvents to dioxin) treated.
