  • 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, ...


  • 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 ...

  • 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. ...

  • 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 ...


  • SITE Technology Capsule - DARAMEND Bioremediation Technology

    GRACE Bioremediation Technologies’ DARAMENDTM Bioremediation Technology is an amendment-enhancedbioremediation technology for soils and sediments contaminated with a wide variety of organic contaminants includingchlorinated phenols, polynuclear aromatic hydrocarbons (PAHs) and petroleum hydrocarbons. The technology may be applied ex situ to sediment and soil and in situ to near-surface soils. The ...


  • In-situ bioremediation technology tested in Northern Italy

    In-situ groundwater treatment is experiencing rapid growth at contaminated sites, so consultants, environmental engineers, hydrogeologists, and regulators must not only stay abreast of emerging remedies, they must strive to objectively select the most natural and cost-effective solutions available. The Italian natural philosopher and mathematician, Galileo Galilei (1564-1642) wrote that ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • SITE Innovative Technology Evaluation Report - DARAMEND Bioremediation Technology

    This report summarizes the results and activities of the demonstration of GRACE Bioremediation Technologies’ DARAMENDTM Bioremediation Technology for the treatment of soils contaminated with polynuclear aromatic hydrocarbons (PAHs) and Chlorinated Phenols (CPs), including pentachlorophenol (PCP). The primary market for theDARAMENDTM technology consists of industrial wood preserving facilities ...


  • Bioremediation of Effluent the Pulp and Paper Industry

    The treatment of industrial effluent from the paper manufacturing facilities in British Columbia is a major concern because the effluent is discharged into prime salmon habitat in the marine environment (Cross, 1994). High levels of biological oxygen demand (BOD) in the effluent reduce the dissolved oxygen (DO) available to species in the marine environment. In 1988, the Federal Department of ...


  • 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 ...
