  • F4 Spill In Situ Bioremediation Applications

    F4 Completed an in situ water bioremediation program of Bio-ReClaim in northern Alberta; a pipeline leaked crude oil over a 14 hectare area in muskeg. Alberta Environment (AEP) allowed the in situ water application of Bio-Reclaim by F4 Environmental. Keeping in mind the application was performed without any ground disturbance and extremely cost effective compared to the ...

  • Improving bioremediation

    Sustainability is becoming a benchmark for the quality of companies who offer remediation solutions, the technologies that they develop and offer commercially, as well as the entire projects where they are used. It is, in essence, not something that can be simply ignored in the months and years ahead if standards are to continue to improve, says Tom Hayes of Ecologia. The sustainability ...

  • 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 ...

  • 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 ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Cost Savings with Bioremediation

    Introduction Prior operations at a former plating and hard anodizing facility in Santa Clara, California resulted in tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (DCE) impacts to soil and groundwater. In 1987, a groundwater monitoring program was implemented to monitor the plume. In 1998, CDM performed a natural attenuation evaluation for ...

  • 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 ...
