Surfactant flushing

Surfactant flushing

Description technique

Injecting a molecule with a polar and apolar side increases the solubility of compounds in water. This leads to a more rapid extraction of the contamination through the water phase.

Applicability
This technique is applicable to poorly water soluble contaminants, such as mineral oil, PAHs, CVOC and pesticides. The technique can be applied for the saturated and unsaturated zone and requires a moderate to well-drained soil. Surfactant flushing is applied to the source of the contamination. The technique is often combined with pump and treat and bioremediation.
Comments
The duration of this technique is several weeks to months. The site disturbance is low. The extracted fluid should however be treated aboveground.
