LNAPL-Recovery |
|
|
With a GCW it is possible to remove non-miscible liquids of lower density than water (LNAPL) from an aquifer. In order to remove light non aqueous liquids floating on the groundwater, the GCW is operated in a reverse mode. The LNAPL is removed by means of a sensor-controlled, pneumatically-driven submersible pump. Thus it is made sure that just pure phase and no groundwater is extracted.
