  • Bioaugmentation Following ISCO Treatment

    CL-Out bioaugmentation was implemented following ISCO treatment of TCE-contaminated ground water.  Through bioaugmentation the ground water remediation was complated and ground water conditions were restored in 30 days. Background The chlorinated solvent trichloroethylene (TCE) was discovered in ground water at a manufacturing facility in eastern Massachusetts. ISCO was selected for ...

  • Bioaugmentation for accelerated in-situ anaerobic bioremediation

    A successful anaerobic bioaugmentation was carried out on a trichloroethene (TCE)-contaminated aquifer at Dover Air Force Base, DE, using a microbial enrichment culture capable of dechlorinating TCE to ethene. A hydraulically controlled pilot system 12   18 m was constructed 15 m below ground surface in an alluvial aquifer to introduce nutrients and substrate into the groundwater. ...

  • Modeling bioaugmentation with nitrifiers in membrane bioreactors

    Bioaugmentation with nitrifiers was studied using two pilot-scale membrane bioreactors, with the purpose of assessing the suitability of state-of-the-art activated sludge models (ASMs) in predicting the efficiency of bioaugmentation as a function of operating conditions. It was demonstrated that the temperature difference between seeding and seeded reactors (ΔT) affects ...

  • 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 ...

  • Bioaugmentation by horizontal injection to remediate petroleum in tight soils

    In situ remediation is a contact sport, requiring contact between the microbes and contamination. Clay-rich soils are particularly challenging as the low permeability limits effective distribution of inoculants. While numerous closely-spaced injection points can improve the distribution of inoculants, this approach is usually not possible at active properties. Horizontal drilling was used on the ...

  • Bioaugmentation to Treat Chlorinated Solvents in Fractured Bedrock

    ABSTRACT: An in situ bioremediation pilot study was performed at a former industrial site in New Jersey where groundwater has been impacted by historical releases of chlorinated solvents. The target area for treatment is a fractured, intermediate bedrock zone. The remedial objective at the Site is to treat the groundwater while minimizing the impact of the remedial system on the re-development of ...

  • Bioaugmentation and Biostimulation Create Conditions for Successful Site Remediation

    CASE SUMMARY Dry Cleaning Operations, Coral Springs, FL A subsurface chlorinated solvent plume formed as the result of dry cleaning operations and migrated beneath an onsitestructure. Over a 6-month period, the concentration of chlorinated solvents increased from 6,000 to 15,000 partsper billion (ppb). A low-cost, in-situ remedial strategy was sought to treat the ...

  • KB-1® Bioaugmentation Leading to Site Closure

    Problem DefinitionIn 2004, the site was an active manufacturing facility with plume trichloroethene (TCE) concentrations ranging from 1 to 20 milligrams per liter (mg/L), and hexavalent chromium (Cr[VI]) ranging from 0.5 to 7 mg/L. Intermediate degradation products of TCE were present in only trace concentrations in this primarily aerobic aquifer. The site source area was excavated in March ...

  • Bioaugmentation is a cost-effective and sustainable remediation alternative

    Selecting a remediation alternative that is compatible with the natural soil and ground water conditions is not only a more sustainable approach, but leads to significant savings. Comparison between bioaugmentation and other remediation methods in the five recognized sustainability criteria demonstrates the advantages of bioaugmentation. While this paper is nota complete quantitative analysis, it ...

  • The Effects of Bioaugmentation in Collection System on WWTP Operations

    In 2004 the wastewater treatment plant in the Town of Orange Park had a very unique problem. The Town was in violation of the current Water Quality Based Effluent Limits (WQBEL) permit while they were simultaneously planning for the even more stringent, Basin Management Action Plan (BMAP) permit to take effect in 2008. The Town needed to address both long and short term wastewater treatment ...

  • Bioaugmentation In Sewer Network Reduces Sludge Production

    This article describes the effectiveness of bioaugmentation in the sewer network as a strategy to reduce sludge production. Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing ...

  • The use of biostimulation and bioaugmentation to remove phenanthrene from soil

    Biostimulation and bioaugmentation are commonly employed as technologies to remediate numerous environmental problems. In the last few decades, both technologies have been used to treat polyaromatic hydrocarbons (PAHs). This paper presents a brief survey of some bioremediation aspects, with particular reference to phenanthrene removal from soil, since this compound is the main model substrate for ...

  • Bioaugmentation/Waste Water Treatment in Livestock - Case Study

    What is it? The bioaugmentation is an innovative technology which consists in an increase of selected bacteria to help naturally the biological process of organic compounds degradation. It is proper to dose in any effluent type and wastewater treatment system, which no longer has enough capacity or has an inefficient performance. These products facilitate the reduction ...

  • Full-scale KB-1® Bioaugmented Biobarrier for TCE Plume Containment

    Problem DefinitionThe site is a former manufacturing facility, where a historic trichloroethene (TCE) release created a plume 1,100 feet wide and 7,000 feet long averaging 3,600 micrograms per liter (μg/ L) TCE, with a groundwater velocity of about 2 feet per day. Prior to biostimulation with electron donor, the groundwater conditions ranged from aerobic to mildly reducing and Gene-Trac DNA ...

  • Using bioaugmentation to reduce risks and costs associated with vapor intrusion

    The risk driver for remedial action on many sites is potential vapor intrusion hazard. While mitigation of the vapors entering the structure can reduce the risk to an acceptable level, there are associated long-term monitoring, operation and maintenance costs. Bioremediation of the source of vapors can reduce the risk and eliminate long-term costs. The vapor intrusion risk is managed by ...
