Treatment of oil polluted soil using electrochemical method

This paper aims to investigate the effect of soil contamination by oil on the geotechnical properties of the soil and evaluation of the feasibility of using electrochemical method for the treatment of the contaminated soils. The properties of contaminated soil samples by different proportions of lubricating oil were determined and compared with the properties of uncontaminated soil samples to study the effect of oil contamination on soil properties. The results showed that oil contamination caused deleterious effects on the basic geotechnical properties of the soil. Contaminated samples have been treated using electrochemical treatment method. The properties of treated soil samples were determined and compared with the properties of contaminated and uncontaminated samples to determine the efficiency of electrochemical treatment method. The results showed that geotechnical properties of treated soil samples are significantly improved. The feasibility of using electrochemical treatment method has been prooved. Beside the ability of treating huge amount of soil, the electrochemical treatment methods are characterized by high efficiency and ecological safety.
