Abstract
Microbiological degradation of toxic materials found in wastewater of oil & gas industry is an remarkable breaktrhough considering the recovery of energy and resources. Effective biodegradation systems of toxic materials such as phenol and ammonia involves the ideal combination of microbial cultures against toxicity of the chemical compounds and technological solutions improve the solid and efficient performance. In this work, the combination of bacterial consortiums that can reduce the concentration of toxic and organic materials in wastewater is analyzed to define operative control strategies to raise the stability of the process. Laboratory experiments were conducted to investigate the performance of PT Pertamina (Persero)^s formulated bacterial consortiums in degradation of organic compounds contained in waste water from Indonesian oil field under aerobic conditions using colorimetric, spectrophotometric and gravimetric methods. The degradation process of wastewater by formulated bacterial consortiums was increased compared with that of the single ones. The results showed that biodegradation is cost-effective, environmentally friendly treatment for wastewater of oil & gas industry.
