  • 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 ...

  • 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 ...


  • 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 ...

  • 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. ...

  • Bioremediation in Denmark - a case study

    Back in the 1990s the closure of several fuel stations in Denmark led to extensive land contamination as underground storage tanks gradually began leaking. After six years of attempted clean-up by the companies concerned the regulatory bodies concluded the situation had not been sufficiently addressed. As a result they refused to complete payment schedules which were based on the success of the ...

  • In Situ Bioremediation - Technology Overview

    ABSTRACT Bioremediation is a managed or spontaneous process in which microbiological processes are used to degrade or transform contaminants to less toxic or nontoxic forms, thereby mitigating or eliminating environmental contamination. In the presence of sufficient oxygen (aerobic conditions) and nutrients, microorganisms will ultimately convert many organic contaminants to carbon dioxide, ...


  • 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 ...

  • An Introduction to Bioremediation and its Applications

    A variety of toxic chemicals, metals, and effluents are created and used in industrial processes. These elements need to be degraded to ensure that they do not harm the environment when disposed. A specialized process and equipment are required to perform this task. This is where bioremediation comes in. What is Bioremediation, and what are its Types? In simple ...

  • Surfactant enhanced bioremediation (SEB)

    Surfactant Enhanced Bioremediation (SEB®) using Ivey-sol® involve the use of Ivey-sol formulations which are patented non-ionic surfactant mixtures used in the in-situ and ex-situ treatment of petroleum hydrocarbons, heavy metals, and more recently radioactive type contaminated waste. These surfactant formulations have the ability to enhance soil biodegradation. During In-situ and Ex-situ ...

  • Petrox® bioremediation of trimethylbenzene isomers

    Remediation of trimethylbenzene isomers (TMB) is particularly challenging, but effective options including bioremediation are available. TMB is has characteristics similar to the BTEX compounds and some similar to middle range fractions such as naphthalene. These characteristics are summarized in the following table. The solubility of TMB is much lower than BTEX compounds, but much higher than ...

  • A Citizen`s Guide to Bioremediation

    What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...

  • Bioremediation Accelerates Brownfield Cleanup

    Untitled Document Bioremediation, using CL-out microbes, clears the obstacles to Brownfield redevelopment by reducing wells contaminant concentrations in groundwater and removing the ...

  • 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 ...

  • Peroxygen Mediated Bioremediation of MTBE.

    ABSTRACT: Evidence is mounting, from laboratory and field studies, that oxygen plays a role in the bioremediation of methyl tertiary butyl ether (MTBE). Our experience with a number of commercial applications of peroxygen, in the form of Oxygen Release Compound (ORCâ), correlates the provision of enhanced aerobic conditions with enhanced MTBE biodegradation. Subsequent laboratory and field ...

  • 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 ground water by treatment of soil at source with Vaporremed

    A heating oil company during servicing of a home in PA released almost 150 gallons of heating oil that seeped into the basement and below. Ground water was shallow and PA DEP wanted to ensure that the contamination did not pollute the water. The environment company overlooking the cleanup decided to use VaporRemed to reduce the fumes. In three weeks time the level of contamination of the soil and ...

  • 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 ...
