  • 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 ...

  • 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 ...

  • SEB Surfactant Enhanced Bioremediation Process Improves F3 & F4 Bioremediation to CCME Guidelines - Case Study

    SEB Surfactant Enhanced Bioremediation process successfully cleans >4,000 Tons of F3 and F4 hydrocarbon contaminated soils at a remote site in Alberta. The SEB process was employed when the subject soils would not respond well to a conventional ex-situ bioremediation treatment. So after a 20 month period of unsuccessful bioremediation; the client and environmental contractor contacted Ivey ...

  • 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 ...

  • Bioremediation of pollutant-contaminated water

    Raw water resources in Kafr El-Sheikh Governorate are affected by many contaminants particularly during the winter season and low demand period of the Nile River, in which water level decreases and organic matter increases resulting in decreased dissolved oxygen, and increased ammonia, nitrite and bacterial load in the water. In this study, physicochemical and microbiological characteristics ...

  • 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 ...

  • 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 ...

  • Biofilm Processes

    The biofilm process is a process which uses a biofilm for the purposes of filtration, bioremediation or barrier formation. A biofilm is a complex and heterogeneous matrix of microorganisms attatched to and growing on a surface. Biofilms are most often found on solid substrates that are exposed ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • 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 ...

  • Assessment of Biodegradation Processes at a Complex Site: Decision Strategy and Implications for Enhanced Bioremediation (PDF)

    A Superfund site in Ohio overlies groundwater contaminated with chlorinated aliphatic hydrocarbons (CAHs)—including perchloroethene (PCE), trichloroethene (TCE), cis-1,2- dichloroethene (DCE), and vinyl chloride (VC) — from prior solvent use and disposal in onsite ponds. The ponds and surface soils containing CAHs were removed in 1984. Historical solvent use and disposal practices produced a ...

  • Award-winning bioremediation case study

    Tamdown won ‘Best Use of a Single Remediation Technique’ at the 2008 Brownfield Briefing awards for their treatment of this former gasworks in Surrey. After applying Alga Power 101 during the screening process, Tamdown constructed vented biopiles housed in large poly-tunnels. Air was continually circulated through the piles using a low vacuum extraction system, preventing the need for ...

  • Nanobite bioremediates a Contaminated harbour - Case study

    When a hydrocarbon is spilled on water, it is very visible – floating on the surface, a blue green sheen clearly visible. When applied to an oil spill on water, Nanobite Liquid will not mix with the water and become diluted. Within a minute it attaches to the hydrocarbon, bonding with it and creating a matrix – an agglomerated gel- that remains on the surface and cannot sink, no ...
