Feasibility Studies of Bioremediation of Hydrocarbon-Contaminated Soils

Abstract

In-situ and ex-situ bioremediation of contaminated soil should be a priori tested during feasibility studies. Three cases of feasibility studies are presented in this paper. Each one concerns a different type of soil contaminated by various hydrocarbons. Different techniques of bioremediation have been chosen in every case. The natural clayey soil and clayey fill soil were provided for the ex-situ treatment but in-situ treatment was applied to sandy soil. The clayey soil was pretreated before subjection to bioremediation. The final results of feasibility studies for all cases show a limited possibility of bio-treatment. The bioremediation needs supplementary optimisation of technological parameters before its application on site.
