Compressed air injection and subsurface air extraction units

In-situ technique

Logisticon supplies compressed air injection and subsurface air extraction systems to stimulate biological activity in the soil. These types of units are usually built into containers and are customised to comply with the specific requirements of the treatment plan.
 

Compressed air injection

In almost all situations, compressed air injection is combined with subsurface air extraction as an ‘in-situ’ technique. This aeration method stimulates biological activity in the soil and also has a limited strip effect.

Subsurface air extraction

Subsurface air extraction is a common supplementary in-situ technique that is used to decontaminate soil. Volatile compounds in the soil are mobilised by means of subsurface air extraction. The pollutant concentrations in the extracted air can be extremely high at the start. That is why the deployment of air filters is usually necessary when using a subsurface air extraction unit.
