  • 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 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Bioaugmentation for accelerated in-situ anaerobic bioremediation

    A successful anaerobic bioaugmentation was carried out on a trichloroethene (TCE)-contaminated aquifer at Dover Air Force Base, DE, using a microbial enrichment culture capable of dechlorinating TCE to ethene. A hydraulically controlled pilot system 12   18 m was constructed 15 m below ground surface in an alluvial aquifer to introduce nutrients and substrate into the groundwater. ...

  • Bioremediation of Kerosene and Diesel Fuel in soil case study

    The United States has a large hazardous waste problem that is threatening both human health and the environment. Current analysis of the nearly 1,200 National Priority List (NPL) sites reveals that about 80% of the sites are contaminated with organic compounds. Clean-up of hazardous waste sites, as a national priority has accelerated the development of bioremediation technologies. Environmental ...

  • Surfactant desorption is key to successful PAH bioremediation

    Formulations which are patented non-ionic surfactant mixtures used in the in situ and ex situ treatment of petroleum hydrocarbons, chlorinated solvents, heavy metals, and more recently PAHs, PCBs and MTBE type contaminated waste are involved in Surfactant Enhanced Bioremediation (SEB®) using Iveysol ®. These surfactant formulations have the ability to enhance soil biodegradation. During in ...

  • Innovative Uses of Compost Bioremediation and Pollution Prevention

    Each year agricultural effluents, industrial residues, and industrial accidents contaminate surface waters, soils, air, streams, and reservoirs. A new compost technology, known as compost bioremediation, is currently being used to restore contaminated soils, manage stormwater, control odors, and degrade volatile organic compounds (VOCs). Compost bioremediation refers to the use of a biological ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...

  • Feasibility study of in-situ bioremediation for nitrobenzene-contaminated groundwater

    Although many studies have simulated in-situ bioremediation of contaminated groundwater, most of them have not considered hydrochemical conditions and indigenous microorganisms, thus potentially rendering results inapplicable to actual in-situ groundwater bioremediation projects. This study focused on a nitrobenzene-contaminated groundwater site located in Jilin City, China. The actual ...
