  • In Situ Biological Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of in situ treatment is that it allows ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ treatment, however, generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • OSEI CEO Mr. Steven Pedigo speaks to the RRT v and VII

    A meeting of Regional Response Team 7 (RRT) member agencies and regional stakeholders convened at 13:00 on April 21, 2015, at 201 North 2nd Street, St. Charles, Missouri (MO). Co-chairs Scott Hayes of the U.S. Environmental Protection Agency (EPA) and Michael Sams of the U.S. Coast Guard (USCG) welcomed participants to the meeting. After attendee self-introductions, Hayes asked if corrections ...

  • Reducing coal plants effluent discharge and waste pit volumes

    The OSEI Corporation manufactures Oil Spill Eater II a first response bioremediation product that utilizes natures own process to convert hydrocarbon contaminants to CO2 by speeding up natures process to remediate hydrocarbons in a matter of days or weeks compared to waiting decades, reducing the time toxic hydrocarbons can adversely effect the environment. OSE II can quickly ...

  • Ex Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...

  • In Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • In Situ Remediation of Perchlorate in Soil and Groundwater, M.S. Thesis, California State University San Bernardino

    This research project documents a technology assessment for in-situ bioremediation of perchlorate (ClO4-). The main goals are to compare methodologies, perform site characterization of soil and groundwater, and perform microcosm and bench scale tests. In this approach, perchlorate is reduced to chloride, requiring an electron donor. The suitability of electron donor amendments will be assessed ...

  • Oxygen and temperature kinetics of aerobic solid-state Biodegradation

    Rates of decomposition are of critical interest to operators of most biodegradation processes, since they determine the length of time the process must continue to achieve a particular extent of decomposition. While the goals of the decomposition process vary widely, ranging from reduction of odors or contaminants to production of high valueadded products, most of these goals are impacted by the ...

  • Aerobics to the Rescue - Using Compatible Technologies to Improve Groundwater Remediation

    Background Increased opportunities for contaminated property redevelopment have propelled property owners to evaluate options for accelerating site remediation. In some cases a containment technology may have been implemented to mitigate the off-property migration of contamination as the most ...

  • Properties and Behavior of Nonhalogenated SVOCs

    Subsurface contamination by nonhalogenated SVOCs potentially exists in four phases: Gaseous phase: contaminants present as vapors in saturated zone. Solid phase: contaminants adsorbed or partitioned onto the soil or aquifer material in both saturated and unsaturated zones. Aqueous phase: contaminants dissolved into pore water according to their solubility in both saturated and ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...
