ISTD treatment of contaminated soil in urban area
By M. MAKOUDI, A. JORDENS, J. HAEMERS In-Situ and Ex-Situ Thermal Desorption (ISTD and ESTD) are technologies based on thermal conduction that can effectively treat volatile and semi-volatile contaminants, independently of large soil heterogeneity. One of its applications is for contaminated properties in urban areas and under existing buildings. The main principle of the technology resides in installing a network of steel pipes acting as an air/soil heat exchanger to heat up the soil by conduction to temperature and pressure conditions at...
