Soil Vapor Extraction Geoengineer

For SVE systems through layered soils, the total flow rate is simply equal to the sum of the individual flow rates (according to equation 3) for each layer. It is also critical to understand how the concentration of the contaminant will change with time during the vapor extraction process.

Soil Vapor Extraction - FRTR Remediation Technologies ...

Soil Vapor Extraction. Introduction. Soil vapor extraction (SVE) involves the application of a vacuum in the vadose zone to induce the controlled flow of air and removal of volatile and some semivolatile contaminants from the subsurface. SVE is applicable to the treatment of contamination located above the water table in unsaturated (vadose) zone soil.

In this scenario, VOC mass extraction during SVE rapidly becomes limited by the rate of contaminant migration out of the fine-grained soils and into the path of soil gas flowing to the extraction point. Even as the rate of mass removal is largely diminished, subsurface transport of the remaining mass may pose an unacceptable source of
