INFLUENCE OF THE DEGREE OF CONTAMINATION ON THE EFFICIENCY OF TREATING OIL POLLUTED LOAMY SOILS WITH THERMAL DESORPTION

The purpose of the hereby paper is to present and interpret the results of the lab experiments performed using soil samples of loamy texture, containing three pollutant concentrations (16710.66; 26300.68 and 39256.68 mg/kg dried substance). In the decontamination process, we opted for three time intervals for keeping the samples in the oven, at 350 °C. The results of the experiments indicate that the efficiency of thermal desorption is influenced by the degree of contamination, which shows the importance of choosing the optimal parameters of the thermal desorption treatment process.
