In the present paper the electro-kinetic depollution is compared with the thermal depollution. The need for a high degree of depollution for soils contaminated with liquid petroleum products is complemented by the economic need not to destroy the pollutant. The study contains a set of experimental data of laboratory activity to compare a new method of depollution with already known and industrially applicable methods. Thermal methods of depollution, combustion and desorption, are methods that have a high degree of depollution, but destroy the pollutant. Electro-kinetic depollution is based on physical principles that cause the migration of the pollutant for the purpose of collecting it without destroying it. The paper presents comparatively the degree of depollution rates achieved by the three methods and the costs obtained for them. In addition, for the electro-kinetic method particular attention has been given to both the recovery of pollutants and the properties of the water used in the process so that it does not become a new source of pollution.
