The hydrocarbons in petroleum sludge are environmental pollutants. It is crucial to eliminate
this type of pollution. In this study, a comprehensive and operational study has been …

The present study concerns the biotreatment of oily sludge of petroleum refineries.
Experiments were performed to assess the degradation potential of the microbial species …

BACKGROUND One of the major parts of global environmental pollution is petroleum
derived products. The purpose of this study was the biodegradation of total petroleum …

The scale-up of petroleum hydrocarbons-rich sludge (PHRS) bioremediation from liquid
medium to a composting method bioaugmentated with two indigenous bacteria, capable of …

Abstract The outcome of different processes in oil refineries is production of hazardous
wastes containing toxic and hardly degradable compounds. Use of chemical processes …

Discharging of non-treated oily sludge from oil refineries has undesirable impacts on the
environment. In this research, the biotreatment of total petroleum hydrocarbons (TPHs) from …

The main objective of this study was to evaluate the effect of oily sludge concentration on its
biodegradability in soil. Oily sludge was collected and applied to microcosms at full-, half-, or …

Microbial degradation of hydrocarbons in soils polluted by oil-based drilling mud and
cuttings has been investigated by static methods such as composting or biopiling …

BACKGROUND Considerable volumes of petrochemical oily sludge can be generated from
oil production and processing activities. Total petroleum hydrocarbons (TPH) contained in …

Field-scale bioremediation of oily sludge in prepared beds was studied at Shengli oilfield in
northern China. The influence of manure, coarse sand, sawdust, a specialized microbial …
