  • A Comparison of Three Wastewater Collection System VOC Emissions Models

    Three models were compared to determine their ability to accurately predict emissions from two wastewater collection system components; gravity flow reaches and drop structures. Models investigated included the INTERCEPTOR Model, TOXCHEM+ and WATER9.Data used to perform the analysis were obtained from published literature. A total of 128 individual runs per model were completed in performing the ...

  • Optimising laboratory environment for successful IVF

    The London Women’s Clinic in Cardiff (LWC Wales) is one of ten clinics within its group which collectively provide expert fertility treatment to families across England and Wales. When it comes to IVF and fertility treatment there is no ‘off-the-shelf’ or ‘one size fits all’ solution and, as such, the medical teams produce a bespoke fertility programme for each and ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • BP (Global VOC losses)

    Reducing costs BP have demonstrated their ongoing commitment to reducing the cost and impact of hydrocarbon losses from their refineries. This implementation of Monitor-Web Server has been customised to manage the collection of worldwide refinery losses data and share up to date performance information throughout the ...


  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Common Treatment Train for Halogenated VOCs

    In general, no single technology can remediate an entire site. Several treatment technologies are usually combined at a single site to form what is known as a treatment train. A system diagram of a common treatment train for halogenated VOCs is illustrated below. A ground water pumping system is used to pull contaminated water from the subsurface. The VOC contaminated water is pumped to a liquid ...

  • Removal of VOCs from Spent Aerosol Cans.

    There are over three billion aerosol cans manufactured in the U.S. annually, 60% of which are consumed by households. Many of the products contained in these cans, such as paint products, light lubricants, starting fluids, polishes and waxes, and cleaners, contain substantial amounts of volatile organic compounds (VOCs) as solvents and include flammable propellants. As a result, partially empty ...


  • Demonstration of Resin Adsorption Techology for Treatment of VOCs in Groundwater

    Untitled Document ABSTRACT Aberdeen Proving Ground (APG) has been a center for the development, testing, and manufacture of military-related chemicals since World War I, ...

  • Cryogenic Treatment Unit (TU-51) for Recovery of VOCs for Soil Remediation

    A Cryogenic Treatment Unit or TU-51 was developed to apply a cryogenic air treatment process to recover persistent vapor phase volatile organic compounds (VPVOC) having extremely low boiling points. These would include explosive compounds present in the vapor stream. The portable TU-51VPVOC (OEM) operates the following process: vapors are recovered from geologic units via SVE, often from a ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Common Treatment Technologies for Nonhalogenated VOCs in Ground Water, Surface Water and Leachate

    It may be necessary to know other subsurface information to provide remediation of VOCs in the ground water. Treatability studies to characterize the biodegradability may be needed for any biodegradation technology. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Evaluation of the snap sampler for sampling ground water monitoring wells for VOCs and explosives

    A series of laboratory and field studies were conducted to determine the ability of the Snap Sampler to recover representative concentrations of VOC and explosives in ground water. For the laboratory studies, statistical analyses of the data (for each analyte) were conducted to determine if the concentrations of analytes in samples taken with the Snap Sampler were significantly different from ...

  • Evaluation of Spatial and Temporal Variability in VOC Concentrations at Vapor Intrusion Investigation Sites

    ABSTRACT As vapor intrusion has become an increasing concern at corrective action sites, the USEPA and a number of state regulatory agencies have recently issued guidance documents covering the collection of subsurface gas, and above-ground air samples during vapor intrusion investigations. Most of these guidance documents do not provide specific recommendations concerning the number of each ...

  • A Comparison Between EPA Compendium TO-15 and EPA MEthod 8260B for VOC Determination of Soil Gas

    ABSTRACT Evaluations of vapor intrusion pathways of chemical contaminants often include soil gas measurements to assess the potential for indoor inhalation. No longer just a screening tool, soil gas measurements are requiring a level of quality and defensibility which should be incorporated in soil gas analytical protocols. While both EPA Compendium Method TO-15 and EPA SW-S46 Method 8260B ...
