This work investigates the ex-situ treatment of groundwater (pump-and-treat) polluted by oil and its derivatives, by in-situ bioremediation of oil and oil derivatives contaminated soil. The investigation used a mixture of contaminated soil from the Novi Sad (Serbia) oil refinery, from a controlled landfill depot (tankvana N8). The bioremediation technique involves the degradation of oil in the aqueous phase, producing microorganisms and saturating the water with oxygen. Water contaminated by oil can be successfully cleansed using a bioreactor treatment, for as long as biodegradable organic material is present. Furthermore, if hydrocarbon degradation is desired, the water must stay longer in the bioreactor. By aeration of the water in the bioreactor, and with enough nitrogen and phosphorus present, the lower concentration of toxic substances, and the presence of degradable and emulgated oil, results in the development of hydrocarbon-oxidising and lipolitic microflora.
