  • Bioremediation of petroleum contaminated Soils in Brazil Using AgroRemed

    At Atuba at the corporate site of COPEL, a state owned utility company, soil was heavily contaminated with transformer oil due to a long history of contamination since 1964 probably due to unsafe practices of storage and cleanup. The level of contamination measures as TPH in soil was as high as 766,695 ppm and much of the contamination was at a depth of 1 meter. The site is located on a hill and ...

  • Bioremediation of Volatile Petroleum Hydrocarbons (VPH) and Extractable Petroleum Hydrocarbons (EPH) - Milford

    Objectives of the Case Study Place bioremediation in the overall context of combined remedial actions to achieve site objectives ...

  • 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. ...

  • 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 ...

  • Bioremediation With The Activated Peat Moss Product In A Savanna Soil Affected By Spilled Petroleum

    The preservation of environment is fundamental in order to get a self sustainable development, by keeping a harmonic relationship between oil exploration and environmental equilibrium. This is a necessary condition in order to share the oil production with other economic activities like agriculture and cattle production. In reality, the oil production is the most important factor in the national ...

  • Bioremediation of petroleum hydrocarbons through landfarming: Are simplicity and cost-effectiveness the only advantages?

    The biological removal of petroleum products using landfarming has been applied commercially in large scale with relative success. The technology has been widely used due to its simplicity and cost-effectiveness. However, together with these advantages, there are physical, chemical and biological aspects of the technology that can hamper the remediation process. The dominant pollutant removal ...

  • 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 ...

  • Integrated 3D physical-numerical modelling for simulating bioremediation of petroleum contamination in heterogeneous subsurface environment

    This study presents physical-numerical modelling of petroleum contaminant transport and enhanced in situ bioremediation in heterogeneous subsurface environment. The approach is based on development of a three-dimensional multi-layered physical model coupled with a three-dimensional multiphase multi-component numerical model. An experimental scheme was designed to conduct 40-day benzene transport, ...

  • 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 ...

  • Biodegradation of total petroleum hydrocarbon (TPH) in Jordanian petroleum sludge

    Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environment-friendly treatment for oil-contaminated sites. In this study, the results are presented concerning a laboratory screening of several natural bacterial consortia and laboratory tests to establish the performance in degradation of hydrocarbons contained in oily ...

  • 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 ...

  • Petrox Bioremediation of Oil Pipeline Leak

    Petrox bioremediation was used to treat unrefined oil that leaked from a pipeline in Texas.  The oil migrated from the impacted soil into ground water and seeped into the surface water in a nearby river.  After one application of Petrox, the oil concentrations in ground water at the source decreased from 600ppm to less than 100 ppm.  Two more treatments reduced the ...

  • Accelerated Petrox® Bioremediation of Naphthalene and Methylnaphthalene Isomers

    Petrox bioaugmentation was implemented at a former gas station UST removal site in Miami, Florida to destroy residual petroleum compounds in ground water.  The UST and contaminated soil were removed.  The residual ground water contamiantion, however, persisted and Petrox bioremediation was implemented to remove the residual low concentrations of MTBE, BTEX, naphthalene and ...
