"In situ" Techniques
We collaborate with IEG-Technologie, a company with an extensive experience in using “in situ” soil and groundwater decontamination technologies. We apply the following technologies developed by IEG-Technologie:
Compact KS 1000 extractor
Compact KS 1000 extractor
Groundwater Circulation Well
Basic scheme
Flow in GCW system with standard circulation.
General flow model in a GCW (“reverse circulation”) modified by Mohrlok and col. In 2003
Several circulation modes.
Stacked groundwater circulation well
Basic scheme.
Vertically stacked Groundwater Circulation Well for biological and physical groundwater remediation (Stacked GCW process)
Soil circular flushing well
Reactive circulation well
In situ well stripping/Vacuum Vaporiser Well
Microbiologically enhanced GCW
Virtually Permeable Reactive Barriers.
Virtually Permeable Reactive Barriers (IEG vPRB) Vertical section.
In situ Chemical Oxidation and Reduction.
Coaxial Groundwater Aeration.
Soil Air Circulation – Vacuum Vapour Extraction.
Thermally enhanced Soil Air Circulation.
Soil Air Circulation-Bioventing.
Multilevel Sampling Wells.
Granular Activated Carbon Adsorbent Systems.
