The extraction of the phases is achieved through manually or automatically adjustable suction lances, which are built into the wells. A vacuum generator provides the necessary negative pressure and extracts or slurps the liquid through suction lances. When the surface of the liquid in the well reaches the lower edge of the suction lance, the unsaturated zone is purified simultaneously by soil vapour extraction >> „bioslurping”.
Multiple phase extraction is suitable for wells and groundwater measuring points with a nominal width of > 1 inch.

• no need for submersible pumps
• suitable for little well diameters
• no defilement of the capillary fringe
• easy drainage of small aquifers

Our technology consists of suitable vacuum generators and various separator systems. The groundwater usually undergoes further treatment >> .
The phase is disposed of.
