| Suitable for | |
The rapid
and effective removal of LNAPL, DNAPL, dissolved and absorbed phase
contaminants in more cohesive soils. |
|
| Technique | |
High-tension
electric power is split into six phases and introduced into the subsurface
via electrodes in hexagonal arrays. Electrical resistance heats the subsoils and groundwaters, vaporising contaminants, which are then removed using conventional vapour extraction techniques for subsequent treatment at surface. |
|
| Benefits | |
This technique is particularly
effective in difficult, more cohesive soils. Very rapid and thorough technique for time limited projects in difficult sites. The electrode arrays can be installed in clusters in the vadose zone or saturated zone simultaneously. |
