WebThermal desorption is a treatment process whereby heat is applied to materials, such as waste soils, sediments, slurries and filter cakes, in order to remove (vaporise) volatile contaminants (e.g. oils and solvents). Along with such volatile contaminants, thermal desorption will also vaporise water contained within the WebThermal treatment can remediate contaminated sites quickly and reliably, but its energy-intensive nature and potential to damage soil properties make it seemingly not sustainable. This review evaluates the potential for thermal treatment to become a sustainable remediation technology based on a comprehensive analysis of the scientific literature.

Thermal Treatment: In Situ

WebBiological treatment/bioremediation uses bacteria to break down substances in the soil. Chemical oxidation converts contaminated soils into non-hazardous soils. Soil stabilisation involves the addition of immobilizing agents to reduce a contaminants’ leachability. Physical methods, like soil washing, use water to separate or remove contaminants. WebDue to these reasons expansive soils need treatment prior to use as an engineering material. These treatments are generally classified into two process, viz. (1) soil modification and (2) soil stabilization.
