bioremediation of hydrocarbon contaminated soil Articles

  • Fast bioremediation of a hydrocarbon contaminated site

    The use of bioremediation has been demonstrated to be a very effective treatment technology for a hydrocarbon contaminated site within a month of starting. In addition to selection and preparation of an appropriate microbial inoculum the other key considerations were effective mixing, addition of suitable nutrients and maintenance of soil moisture levels. Careful management of all these ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • 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 ...

  • 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 ...

  • 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 ...

  • CH#952 - Oil Contaminated Soil

    SITE OWNER: A National Overnight Express Package Company SITE SURVEY: Site and geological surveys revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was the result of two (2) underground storage tanks (UST™). One tank contained waste oil while the other contained new oil. Both tanks had ...

  • In Situ Bioremediation of Soil and Groundwater: A Case Study

    Untitled Document The subject site is located in downtown Denver, Colorado and was formerly operated as a bulk petroleum storage facility. Bulk storage of gasoline, diesel and fuel ...

  • Water repellency in oil contaminated sandy and clayey soils

    Two sites from a humid tropical environment were studied with respect to soil water repellency caused by hydrocarbon contamination. Samples were analyzed for water repellency (molarity ethanol droplet method), total petroleum hydrocarbons, acute toxicity (Microtox) and field capacity. At both sites, water absorption times were ...

  • Enhanced Bioremediation

    Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...

  • Jet A fuel soil contamination - Eaton Corporation

    LOCATION:  Battle Creek, MichiganPROJECT DATE:  January, 1993 to PresentCLIENT:  Eaton Corporation BACKGROUND: Soils and groundwater at this aircraft refueling facility were contaminated with an undetermined amount of Jet A fuel. The geology of the area is glacial outwash sand and gravel and post-glacial alluvium. The water table is located approximately 30 feet below ground level ...

  • Composting of petroleum contaminated soil case study

    Soils contaminated with hydrocarbons are generated during oil and gas production. Remediation by land treatment is a popular, inexpensive option however, in cold climates temperature limits the time available for treatment each year. Companies would prefer an economical, low maintenance treatment alternative which could operate throughout the year in cold climates. Environmental BioTechnologies, ...

  • Bioremediation with compost of a diesel contaminated soil: Monitoring by dehydrogenase activity and basal respiration

    The effect of compost on hydrocarbon degradation was determined during a 120-d incubation period. An evaluation of soil basal respiration and dehydrogenase activity as a monitoring instrument for the bioremediation process of soil contaminated with commercial diesel-oil was carried out. Six soil samples were used: S (control, uncontaminated soil), CS (contaminated soil), CSS (contaminated and ...

  • Combining HVME and Enhanced Bioremediation for Gasoline Contamination in Groundwater

    A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway was ...

  • Contamination at ANA Shipyard

    ANA Shipyard is located on Elizabeth river and during additional construction work, it was discovered that the ground water was contaminated with free product due to soil contaminated with a mixture of oils and greases. Excavation of soil and replacement with clean dirt was not an option since it would contaminate the river. It was recommended by the Virginia DEQ that the cleanup should be done ...

  • Monitoring of petroleum hydrocarbon degradative potential of indigenous microorganisms in ozonated soil

    This study was performed to investigate the petroleum hydrocarbon (PH) degradative potential of indigenous microorganisms in ozonated soil to better develop combined pre-ozonation/bioremediation technology. Diesel-contaminated soils were ozonated for 0–900min. PH and microbial concentrations in the soils decreased with increased ozonation time. The greatest reduction of total PH (TPH, 47.6%) and ...

  • Emission of N2o from Polycyclic Aromatic Hydrocarbons contaminated soil at different water contents added with vermicompost

    Vermicompost is typically applied to improve soil quality, but can be used to remediate hydrocarbon-contaminated soils. Little information is available on how contamination and subsequent bioremediation with vermicompost affects emissions of N2O and CO2, important greenhouse gases. A sandy loam soil with different water contents (40%, 60%, 80% and 100% of water holding capacity (WHC)) was ...

  • Failure of Magnesium Peroxide to Remediate Petroleum Hydrocarbon-Contaminated Sites (PDF)

    Researchers promote magnesium peroxide as a viable method to aerobically bioremediate petroleum hydrocarbons and restore groundwater quality. Suppliers claim that dissolved oxygen released in the saturated zone promotes biological growth for degrading a wide range of hydrocarbons dissolved in water and sorbed onto soil particles. Yet, staff with the CaliforniaRegional Water Quality Control Board, ...
