Study on utilization of leachate as inoculum of microorganism in bioremediation of oil sludge on Total Petroleum
Hydrocarbon (TPH), C/N ratio, Polycyclic Aromatic Hydrocarbon (PAH) and heavy metals content was conducted
during 45 days. The aim of the present work was to assess the ability of leachate inoculum in degrading oil sludge.
The main parameters in this study, TPH and C/N ratio were analyzed within 15 days of interval while PAH and
heavy metals were measured at the beginning of experiment (day 0) and at the end of experiment (day 45).
Supporting parameters such as pH, temperature and humidity of medium were also analyzed. Our finding showed
that the leachate inoculum reduced TPH and Cr content as much as 24.20% and 5.88%, respectively. On the other
hand, C/N ratio in the oil sludge medium 30% increased as much as 1.14%. The PAH compounds that can be
