Alcohol Flushing

The remediation of a chlorinated hydrocarbons (CHC) contaminated aquifer always contains a risk, because of the possibility of uncontrolled downwards mobilization of the CHC into deeper parts of the aquifer. This scenario would be even more harmful to the environment. The application of well known remediation techniques for CHC as e. g. ...

Substrate Release Composition (SRC)

Source-area bioremediation for chlorinated solvents is complicated by the complex migration of DNAPLs and the high proportion of sorbed-phase contaminant mass in the aquifer media compared to the relatively minor CVOC mass in ground water. Desorption of aquifer bound CVOCs is typically the rate-limiting factor for source-area remediation, such ...

Sparging

Sparging signifies the injection of air into the groundwater of the aquifer. The air migrates in fine fissures to the vadose zone. The air injection leads to a stripping of contaminants into the vadose zone and boosts aerobic biodegradation in the groundwater. Contaminated vapour is extracted and treated. Benefit is low energy consumption during ...
