Microbial Degradation of Petroleum Hydrocarbon Contaminants: An Overview
Introduction Petroleum-based products are the major source of energy for industry and daily life. Leaks and accidental spills occur regularly during the exploration, production, refining, transport, and storage of petroleum and petroleum products. The amount of natural crude oil seepage was estimated to be 600,000 metric tons per year with a range of uncertainty of 200,000 metric tons per year ...

Surfactant–enhanced remediation of soils contaminated with petroleum hydrocarbons
An experimental programme was undertaken to reclaim the soils contaminated with petroleum hydrocarbons. Two types of locally available soils, clay with low compressibility and poorly graded sand, were chosen for the study. Both the soils were contaminated with varying percentages of used engine oil and gasoline. Anionic surfactant Sodium Dodecyl Sulphate (SDS) was used to reclaim the contaminated ...

Hydrocarbon-Contaminated Soil Remediation
Hydrocarbons are organic compounds composed of hydrogen and carbon atoms and are the building blocks of many fossil fuels. Petroleum products, such as gasoline, diesel, and oil, are major sources of hydrocarbons. Spills or leaks of these products can result in soil contamination, and if left unaddressed, can have significant environmental and health impacts. In this article, we will discuss the ...

Decontamination of soil contaminated with petroleum grease
Contamination modifies the engineering properties of soil, thereby restricting its further use either as a construction material or as a supporting medium. Due to the scarcity of land, it becomes imperative to reuse the land for infrastructure developmental activities. Out of numerous soil contaminants, automobile grease is one of the most prominent. Considering the cumulative impact of ...

Successful In Situ Remediation of Hydrocarbon Contaminated Soils in South Africa
Location: PepsiCo Frito-Lay Simba Isando, Gauteng, South Africa Use of the vehicle workshop area at the Frito-Lay Simba Isando plant was discontinued due to outsourcing of the distribution chain. An area in front of the wash bay bordered by the workshop and boundary walls had been heavily contaminated by hydrocarbon. This contamination was a mix of petroleum (PRO) and diesel (DRO) range organics ...

Evaluation of The Efficiency of Various Commercial Products for The Bioremediation of Hydrocarbon Contaminated Soil
Bioremediation has become an important method for the treatment of terrestrial oil spills and is often favoured over strictly physical-chemical methods. In this study, enzymatic analyses and signature lipid biomarkers were employed to evaluate the efficacy of selected bioremediation products on control and oil contaminated soil plots. It is envisioned that these biological indicators may be used ...

Biosorption of Congo Red from aqueous solution by Bacillus weihenstephanensis RI12; effect of SPB1 biosurfactant addition on biodecolorization potency
Bacillus weihenstephanensis RI12, isolated from hydrocarbon contaminated soil, was assessed for Congo Red bio-treatment potency. Results suggested the potential of this bacterium for use in effective treatment of Congo Red contaminated wastewaters under shaking conditions at acidic and neutral pH value. The strain could tolerate higher doses of dyes as it could decolorize up to 1,000 ...

Biotechnology of hydrocarbon bioremediation in soil washing slurry
Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

SEB Surfactant Enhanced Bioremediation Process Improves F3 & F4 Bioremediation to CCME Guidelines - Case Study
SEB Surfactant Enhanced Bioremediation process successfully cleans >4,000 Tons of F3 and F4 hydrocarbon contaminated soils at a remote site in Alberta. The SEB process was employed when the subject soils would not respond well to a conventional ex-situ bioremediation treatment. So after a 20 month period of unsuccessful bioremediation; the client and environmental contractor contacted Ivey ...

Polycyclic aromatic hydrocarbons in Niger Delta soil: contamination sources and profiles
Abstract The distribution and sources of PAHs in soil as well as PAHs profiles have been investigated in areas with anthropogenic pollution in the Niger Delta (Nigeria) such as Warri and Ughelli. PAHs were identified in 21 soil samples (0- 10cm upper layer) collected in May, 2003. The typical total PAHs level in Niger Delta soil ranged from 182 ± 112 – to - 433 ±256 ìg/kg dw. PAH ...

Bioremediation applied to high pH contaminated soil washing slurry
BioFuture Ltd. in conjunction with General Smontaggi SpA have used applied environmental engineering and bioaugmentation to remediate hydrocarbon contaminated soil washing slurry. The soil washing slurry had been treated using lime to dry and stabilise it for transport to special landfill for disposal. The starting pH was 12.55 and it was successfully bioremediated so that it could be used as a ...

Distribution of polycyclic aromatic hydrocarbons in soils and corns, and its risk assessment in summer around Zhongyuan, oil field, China
The purpose of this study was to determine the degree of contamination with polycyclic aromatic hydrocarbons (PAHs) in samples of soils, and corn around three different oily sludges in Zhongyuan oil field in summer. The contents of PAHs in the soil samples from high to low were the Third Wenming oil sludge (3W) > the Third Mazhai oil sludge (3M) > the Fourth Wen'er oil sludge (4W). The contents ...

Thermal Desorption
Untitled Document Introduction: Thermal desorption is a physical separation process and is not designed to destroy organics. Wastes are heated to volatilize water and organic contaminants. A carrier gas or vacuum system transports volatilized water and organics to the gas treatment system. The bed temperatures and residence times designed into these systems will volatilize ...
