Soil Vapor Extraction (SVE) Technology

Soil Vapor Extraction (SVE) is an efficient remediation technology for treating volatile and semi-volatile contaminants in soil. For semi-volatile pollutants, bio-enhanced SVE methods can be applied.

Implementation Method

1. Well Installation:

• Install vertical wells or horizontal wells in contaminated areas.

2. Air Injection:

• Inject air into the subsurface to volatilize volatile/semi-volatile components in the contaminated media.

3. Contaminant Extraction:

• Extract volatilized/semi-volatile components through dedicated extraction wells.

• Collect and direct contaminants to downstream air treatment systems.

• Targeted Pollutant Types:

  Volatile Organic Compounds (VOCs)

  Semi-Volatile Organic Compounds (SVOCs)

• Process Efficiency:

     Enhanced by bioaugmentation for recalcitrant semi-volatile pollutants.

• System Scalability:

      Adaptable to both vertical and horizontal well configurations.
