Abstract

This study has focused on the adaptation of washing techniques to decontamination of soils from the old sites of coking plants, which are essentially contaminated by polycyclic aromatic hydrocarbons (PAH). Tests were carried out in the laboratory and the pilot scale on different samples from former coking plants and gasworks. The pilot scale tests allowed a 90% reduction of the PAH content of the soil fraction over 1mm and treatment was based on separation techniques and density differences. For the soil fraction under 1mm tests were carried out in the laboratory using washing techniques based on surface properties and the parameters that ensure a PAH's decontamination of polluted soil were determined. These techniques could be applied to other forms of pollution, such as heavy metal contamination.
