  • 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 ...

  • 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 ...

  • 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 ...

  • Bioremediation of synthetic fatliquors under microaerobic condition

    Synthetic fatliquors are useful as a fatliquoring agent, flotation agent and emulsifying agent in a wide range of industrial applications such as leather, pharmacy and farm chemicals. These fatliquors remain recalcitrant to natural biota in existing treatment plants. In the present study, the isolated microaerophilic Serratia sp. HA1 strain CSMB3 is capable of utilizing structurally different ...

  • Comparison of Reducing Agents for Dechlorination in a Simulated Aquifer (PDF)

    A simulated aquifer system (Aquifer Simulation Vessel – ASV) was used to study the efficacy of various reducing agents to assist microbial dechlorination. The soil samples are homogenized and the soil is packed into 6.0-foot long tubes with an internal diameter of 5.75 inches. Flow rates can be calibrated for flow at 0.1 to 2.0 feet/day. The system has a volume of 2025.44 in3.  A solution of ...

  • 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 ...

  • Enhanced Bioremediation of High Contaminant Concentrations in Source Residual Area (PDF)

    Although enhanced bioremediation has proven to be effective at many sites, typically it has been applied to relatively low contaminant concentrations and in relatively permeable media. The project site described herein is an application that potentially extends the practical limits of in situ bioremediation applications. An active eyewear manufacturing facility located in Western NY was found to ...

  • Enhanced bioremediation of crude oil in polluted beach sand by the combination of bioaugmentation and biodiesel

    Biodiesel produced from rapeseed oil was used as a cost-effective and sustainable agent to enhance crude oil biodegradation in sand microcosms. The initial concentration of crude oil and total petroleum hydrocarbon (TPH) was 20,000 and 18,750 mg/kg, respectively. The mass ratio of biodiesel to crude oil was 0 (designated T1), 1:10 (designated T2), 1:4 (designated T3), and 1:2 (designated T4). ...

  • Composting of petroleum contaminated soil case study

    Soils contaminated with hydrocarbons are generated during oil and gas production. Remediation by land treatment is a popular, inexpensive option however, in cold climates temperature limits the time available for treatment each year. Companies would prefer an economical, low maintenance treatment alternative which could operate throughout the year in cold climates. Environmental BioTechnologies, ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • Landfarming

    Introduction Landfarming is a full-scale bioremediation technology, which usually incorporates liners and other methods to control leaching of contaminants, which requires excavation and placement of contaminated soils, sediments, or sludges. Contaminated media is applied into lined beds and periodically turned over or tilled to aerate the waste. Soil conditions are often controlled to ...

  • DOD evaluates bioaugmentation for remediating low-pH aquifers

    The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

  • In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

    A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...
