Abstract

This research was focused on treating oil sludge from petroleum industry’s waste which can cause serious environmental problems. Bioremediation is one of the effective and promising ways to manage oil sludge with biological activity. The ability of the bacterial consortium was used to reduce the value of Total Petroleum Hydrocarbon (TPH) with a biopile system. The pilot scale biopile research design used a mixture of soil, bacterial consortium nutrients, with sawdust variations of 0%, 15%, 30% and 45%. This biopile system was conditioned by the addition of oxygen to maintain aerobic conditions, incubated in atmospheric temperatures and two weekly sampling within 56 days. The combination of treatment at the best for total bacterial count was 7.21 x 107 CFU/g and the percentage of TPH degradation reached 81% at the end of the study period. Based on the results it can be concluded that biopile is able to be an effective, economical and environmentally friendly choice for the management of oil sludge.
