  • Vapor intrusion pathway investigation

    The BEACON samplers defined the vapor intrusion of tetrachloroethene and 1,1-dichloroethene, while the Summa canisters (EPA Method TO-15) reported all non-detects. The BEACON survey enabled detection of some chemicals at levels below the Summa canisters practical quantitation limits providing a more complete and realistic vapor intrusion exposure pathway evaluation. Based on the defined vapor ...

  • When vapors intrude...

    Vapor intrusion (VI) is the migration of gas-phase chemicals from the subsurface into buildings or other structures. It is one of the exposure pathways that should be considered when performing a site human health risk assessment and can be an important issue at sites with subsurface contamination due to petroleum fuels or chlorinated solvents. This article provides a “big picture” overview for ...

  • Soil Vapor Extraction (Ex Situ)

    Introduction: Ex situ soil vapor extraction (SVE) is a full-scale technology in which soil is excavated and placed over a network of aboveground piping to which a vacuum is applied to encourage volatilization of organics. Soil piles are generally covered with a geomembrane to prevent volatile emissions and to prevent the soil from becoming saturated by precipitation. The process includes a ...

  • Vapor Steamers for Tile and Grout Maintenance

    Tile and grout cleaning is undoubtedly a tiresome and time-consuming job. Tiled floors are normally used in areas that experience heavy traffic. As a result, the floors can get quite dull and dirty at the end of the day. Then, there is the issue of grout, a highly porous surface that quickly absorbs dirt and develops stains. Rigorous scrubbing can wear away the grout and spoil its appeal. For ...

  • Thermally Enhanced Soil Vapor Extraction

    Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

  • Modification of tubular ceramic membranes with carbon nanotubes using catalytic chemical vapor deposition

    In this study, carbon nanotubes (CNTs) were successfully grown on tubular ceramic membranes using the catalytic chemical vapor deposition (CCVD) method. CNTs were synthesized at 650°C for 3–6 h under a 120 mL min−1 flow of C2H6 on ceramic membranes impregnated with iron salt. The synthesis procedure was beforehand optimized in terms of catalyst amount, impregnation duration ...
