Soil vapor extraction is an in situ remedial technology used at many gasoline-impacted sites as a means of recovering vapors from unsaturated soils. It operates when a vacuum is applied to the soil matrix through an extraction well(s), usually placed near a known source area. Soil vapor extraction (SVE) is used to remediate unsaturated (vadose) zone soil.

A vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile organic contaminants from the soil. SVE usually is performed in situ; however, in some cases, it can be used as an ex situ technology.

Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, ). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase.

Soil vapor extraction (SVE) uses vacuum pressure to remove volatile and some semi-volatile contaminants (VOCs and SVOCs) from the soil. The gas leaving the soil may be treated or destroyed, depending on local and state air discharge regulations. Description: Figure Typical In Situ Soil Vapor Extraction System Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil.

Soil Vapor Extraction Technology Details. SVE is an accepted cost effective technique for removing VOCs and motor fuels from contaminated soil. The book identifies current SVE technologies, as well as additional research needed in site characterization, pilot systems, full scale system design and operation, attainment of clean-up criteria.

Soil vapor extraction (SVE) systems are being used in increasing numbers due to many advantages these systems hold over other soil treatment technologies.

VE systems appear to be simple in design and operation, yet the fundamentals governing subsurface vapor transport are quite complex. n view of this complexity, an expert workshop was held to discuss the state-of-the-art of the technology.

SVE systems appear to be simple in design and operation, yet the fundamentals governing subsurface vapor transport are quite complex. In view of this complexity, an expert workshop was held to discuss the state of the art of the.

Soil vapor extraction (SVE), a prevalent remediation approach for volatile contaminants in the vadose zone, may exhibit a diminishing rate of contaminant extraction over time due to diminishing contaminant mass and/or slow rates of removal for contamination in low-permeability zones.

Product Information. From the Preface Soil vapor extraction within the last few years has gone from being an innovative, relatively untried technology which was viewed with some distrust, to being one of the most reliable, accepted, and cost-effective of the techniques available for the remediation of.
