1. SVE(soil vapor extraction-in situ)
1) principle
Soil vapor extraction, also known as soil
venting or vacuum extraction, is a cleanup
technology commonly used to remove
VOCs in vapor from contaminated property.
4) Application
Contaminant : VOCs
Place : gas station base, industrial base,
military base
Layer : contaminated layer on the ground
water surface
Concentration reductions and constituent concentrations are difficult to achieve.
May not be effective for high constituent concentrations
Presence of significant heavy metal concentrations may inhibit microbial growth.
Volatile constituents tend to evaporate
Requires a large land area
