  • 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. ...

  • 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 ...

  • 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 ...

  • Enhanced Bioremediation in Clay Soils (PDF)

    This case study evaluates the full-scale in-situ application of an electron donor to enhance biodegradation of chlorinated solvents in clay soils and groundwater beneath an active light industrial property in a congested urban setting.A pilot test was successful by varying degrees in three test areas as shown by the production of biodegradation daughter products and microbial end products. The ...

  • Case study - Coupling ISCO and anaerobic bioremediation at Kings Bay Naval Submarine Base wins state award of environmental excellence

    Site Description:  The Naval Submarine Base in Kings Bay, Georgia (a former landfill) was impacted with VOCs due to buried drums. Contaminants:  PCE and its degradation products at concentrations of 9,000 ug/L. Based on investigation efforts conducted by the Navy, DNAPL was also suspected. Remedial Challenge:  The groundwater ...

  • 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 ...

  • A Pilot Study Using HRCTM to Enhance Bioremediation of CAHs.

    ABSTRACT: The effect of Hydrogen Release Compound (HRCTM) in enhancing the anaerobic bioremediation of chlorinated aliphatic hydrocarbons (CAHs) was observed in a single well pilot study. HRC is a proprietary, environmentally safe, food quality, polylactate ester formulated for the slow release of lactic acid upon hydration. Microbes metabolize the lactic acid releases by HRC and produce ...

  • Field Application of a Lactic Acid Ester for PCE Bioremediation.

    ABSTRACT: As part of a strategy to enhance reductive dechlorination with a timed release of hydrogen, an application of glycerol polylactate (GPL) was made to a dry cleaner site contaminated with perchloroethylene (PCE). GPL is one of several proprietary lactic acid esters sold commercially as Hydrogen Release Compound (HRCTM). When HRC contacts the saturated contaminated zone, the lactic acid ...

  • The Use of Hydrogen Release Compound (HRC) for CAH Bioremediation.

    Hydrogen Release Compound (HRC™) is a simple, passive, low-cost and long-term option for the anaerobic bioremediation of chlorinated aliphatic hydrocarbons (CAHs) via a reductive dehalogenation pathway. Applications to other classes of chlorinated compounds that are anaerobically degradable by this mechanism are under investigation. HRC should be viewed as a tool for the enhancement of natural ...

  • Bioremediation of Nitrochlorobenzene, Nitroaniline, Chloroaniline, and Other Organics in Groundwater.

    ABSTRACT: The uppermost aquifer beneath a chemical plant contains residual concentrations of o-nitrochlorobenzene from a tank car spill, as well as other plant-related organic compounds of concern (COC), including 2-nitroaniline and o-chloroaniline. The aquifer consists of low permeability clays and silts, and produces only a few gallons of groundwater per day from a shallow ...

  • Enhanced Aerobic Bioremediation of Petroleum UST Releases in Puerto Rico.

    Abstract: Releases of petroleum compounds from underground storage tanks (USTs) containing diesel fuel and gasoline are a serious and increasingly prevalent problem in Puerto Rico. Remediation of groundwater impacted by these releases utilizing common methodologies can be quite costly and require long periods of time to implement. Oxygen is often the limiting factor retarding optimal ...
