The subsurface contamination with Petroleum Hydrocarbon (PH) can cause serious environmental problems such as the effect to human health or the decline of soil-bearing capacity. Numerous remediation technologies for PH has been developed, and one demonstrated technology is well known as bioremediation. In this study, our goal is to recycle the soil which contaminated with PH using the bio-pile and flotation methods. The bio-pile as one of the bioremediation methods is heaping contaminated soil in which the pipe for supplying air, water and nutrients were installed to activate the indigenous microorganisms in the soil to degrade contaminants. Heap also contains sawdust to keep ventilation for air and initial nutrients in proportion to the amount of contaminants. During this study, oxygen concentration, volatile compounds, number of bacteria, temperature and moisture were monitored. From the fact thatoxygen in the gas decreased from 20 to about 2% and the temperature inside the pile increased from 20 to 40°C, it was confirmed the indigenous microorganisms were activated by this method. And Total Petroleum Hydrocarbon (TPH) was finally degraded to about 50% of the initial amount.The soil remediated by the bio-pile still contained 3, 000-5, 000mg/kg of Asphaltene (it shared about 15% of the rest TPH) and 4, 000-8, 000mg/kg of Resin (about 20%) which were not degraded by the microorganisms. For this soil, flotation treatment was conducted sequentially to the rest of PH, and it was confirmed that the TPH concentration of soil could be degraded to less than 1, 000 mg/kg.It was concluded that the combination of this bio-pilewith other methods such as the flotation method could effectively remediate the soil contaminated with PH and remediated soil could be recycled as a clean soil.
