Vacuum Vapour Extraction

Thermally enhanced soil air circulation (TESAC)

Wednesday, 02 April 2008
Soil air circular flow is employed to remediate soils polluted with volatile contaminants (e.g. CHC, BTEX, jet fuels), some semi-volatile contaminants and/or biodegradable substances. Due to the application of low negative pressure, TESAC systems can be implemented in soil, where the horizontally induced flow bypasses contaminants trapped in low-permeability layers.

Vacuum Vapour Extraction

Friday, 15 September 2006

The conventional technique of Soil Vapour Extraction has proven to be a practical and inexpensive method for the removal of volatile and semi-volatile hydrocarbons from the unsaturated zone. Soil Vapour Extraction is conventionally carried out using small-sized boreholes which extend to just under the groundwater table and are outfitted with screens of diameters up to 50 mm. Depending on the size of the equipment and the properties of the soil, blowers are usually operated at pressure differences of 100 to 300 millibars. This high negative pressure draws perched or capillary water into the venting system.

Soil Air Circulation - Bioventing

Tuesday, 12 September 2006

Directed Soil Air Circulation systems (SAC) are employed for the remediation by Bioventing of soil contaminated with volatile hydrocarbons by enhancing the IEG Vacuum Vapor Extraction (IEG VVE) technique. In addition, they can be used to inject gas into the soil for the stimulation of biological or chemical degradation.
