  • Bioremediation of an Oil Spill

    Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...


  • Bioremediation of DNAPL

    Dense non-aqueous phase liquid (DNAPL) are mixtures of organic compounds that when combined have a specific density greater than water, which has a specific density of 1.00. They sink through water and form a separate liquid phase below the water. DNAPL mixtures can include compounds such as chlorinated solvents, PCB oils, coal tars, and creosotes (complex mixtures consisting of polycyclic ...

  • Petrox Bioremediation of Oil Pipeline Leak

    Petrox bioremediation was used to treat unrefined oil that leaked from a pipeline in Texas.  The oil migrated from the impacted soil into ground water and seeped into the surface water in a nearby river.  After one application of Petrox, the oil concentrations in ground water at the source decreased from 600ppm to less than 100 ppm.  Two more treatments reduced the ...

  • 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 ...

  • The Bioremediation Process

    Bioremediation allows natural processes to clean up harmful chemicals in the environment. Microscopic 'bugs' or microbes that live in soil and groundwater like to eat certain harmful chemicals, such as those found in gasoline and oil spills. When microbes completely digest these chemicals, they change them into water and harmless gases such as carbon dioxide. In order for microbes to clean up ...


  • Case Study - BP oil spill bioremediation tests

    CL Solutions, LLC has completed some internal preliminary testing of Munox SR® at the request of our customers and regulators in the Gulf Region. Although, our products have been used to remediate soil and ground water at numerous locations in the region, these tests were undertaken to verify specific applicability to the BP spill. Tar Ball Treatment While manual removal of ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...

  • In Situ Bioremediation of Chlorinated Solvents

    ABSTRACT: In situ bioremediation is ongoing at a former manufacturing facility in Portland, Oregon.  Shallow groundwater at the site was impacted by chlorinated solvents, primarily trichloroethene and degradation products cis-1,2-dichloroethene and vinyl chloride.  In situ chemical oxidation treatment was completed in 2003 via the injection of sodium permanganate in source ...

  • System for bioremediation of effluents

    Executive Summary The remediation process of commercial, municipal, industrial and agricultural wastewaters has employed combinations of sulfuric acid, caustic, petroleum based solvents and synthetic emulsifiers, which are either toxic or generally non-biodegradable. An alternate method using naturally occurring microorganisms has been utilized for many years to facilitate the remediation ...

  • Biodispersion Technology: A Fast-Acting Bioremediation option For Basement Heating Oil Spills

    An environment company was contracted by heating oil company and the insurance company for cleanup of heating oil released in the basement of a home owner in Pennsylvania. The concrete surface was cut open after mopping the free product to reveal underlying soil heavily stained with home heating oil producing strong odors of heating oil. The environment company requested for VaporRemed on a next ...

  • Enhanced anaerobic bioremediation of chlorinated solvents utilizing vegetable oil emulsions

    The use of vegetable oil as an electron donor to enhance the reductive dechlorination of chlorinated solvents as an in situ remediation technology is gaining significant traction. Vegetable oil is a cost-effective slow-release electron donor with greater hydrogen-release efficiency than other electron-donor products. However, neat vegetable oil can inhibit distribution in aquifers due to the oil ...

  • Concurrent bioremediation of perchlorate and 1,1,1-trichloroethane in an emulsified oil barrier

    Abstract A detailed field pilot test was conducted to evaluate the use of edible oil emulsions for enhanced in situ biodegradation of perchlorate and chlorinated solvents in groundwater. Edible oil substrate (EOS®) was injected into a line of ten direct push injection wells over a 2-day period to form a 15-m-long biologically active permeable reactive barrier (bio-barrier). Field ...

  • Enhanced bioremediation of crude oil in polluted beach sand by the combination of bioaugmentation and biodiesel

    Biodiesel produced from rapeseed oil was used as a cost-effective and sustainable agent to enhance crude oil biodegradation in sand microcosms. The initial concentration of crude oil and total petroleum hydrocarbon (TPH) was 20,000 and 18,750 mg/kg, respectively. The mass ratio of biodiesel to crude oil was 0 (designated T1), 1:10 (designated T2), 1:4 (designated T3), and 1:2 (designated T4). ...

  • Bioremediation of diesel oil - derwent island, national trust, united kingdom

    Introduction A spillage of red diesel oil (heating oil) from a holding tank located on Derwent Island in Lake Derwentwater, Cumbria, has been successfully treated using Microbac"s oil degrading bacterial cultures. The spill occurred in the Lake District National Park and a major concern was contamination of the lake water. The main problem associated with the work was access to the island ...

  • Petrol and heating oil bioremediation using EU70 (case study)

    As a result of an accident a tanker lost its load of petrol and heating fuel. A large quantity of fuel approximately 2000 litres soaked into the soil. Analyses revealed that the average level of hydrocarbons present was in the order of 0.55 %. The pollution affected an area of 100 m2 and to a depth of 0.6 m. Our goal was to reduce hydrocarbon levels to the lowest possible value in order to ...
