Oily sludge belongs to the hazardous waste specified in national list. It will directly or indirectly threaten ecological environment and human health. This paper introduces advantages of chemical hot washing oily sludge. discusses main factors affecting treatment effect, Demulsification Mechanism research progress by thermal washing, puts forward some suggestions on future development directio...

Monoaromatic hydrocarbons such as benzene have been found in sludge created by oil production facilities and industries. Benzene is considered as a carcinogenic substrate and biodegradation, primarily under aerobic conditions, is an important environmental process for water and soil associated benzene remediation. Aerococcus sp. strain BPD-6 isolated from petroleum hydrocarbon contaminated oily...

A bacterial strain, PS4040, capable of degrading polycyclic aromatic hydrocarbons for use as the sole carbon source was isolated from oily-sludge-contaminated soil. The 16S rRNA gene showed 98.8% homology to that of Leclercia adecarboxylata. Comparative molecular typing with the clinical strain of L. adecarboxylata revealed that there were few comigrating and few distinct amplimers among them.

Bacillus sp. strain UFRGS-B20 was isolated in 2012 from Brazilian land-farming soil contaminated with petrochemical oily sludge. This strain was subjected to hydrocarbon biodegradation tests, showing degradation rates of up to 60%. Here, we present the 6.82-Mb draft genome sequence of the strain, which contains 2,178 proteins with functional assignments.

The oily sludge treatments catch widespread attention. But, management of is difficult and costly undertaking. oil recovery pyrolysis temperature, heating rate carbon wt.% discussed. recovered aliphatic, aromatic, elemental components gases were obtained with respect to the nitrogen flow rate. present work showed that as increases, both %pyrolysis increases up 600 OC, while char decreases. Beyo...

Cork, a material with great economic, social and environmental importance in Portugal, is also a good oil sorbent that can be used in the remediation of oil spills. The oil-impregnated cork can be easily removed, but requires further treatment. In the case of vegetable oil spills, anaerobic digestion may be a potential solution. This study aims to evaluate the effect of adding cork contaminated...
