Oil-phase Extraction Systems
For the water-less recovery of light non-aqueous phase liquids (LNAPL) from groundwater ARGUS GmbH offers a selection of company-developed extraction systems.
Case study: Oil-phase extraction

Deutsches Gebrauchsmuster 296 03 328.6
The extraction systems are suitable for the following LNAPLs:
The ARGUS-Schlürfkopf-System is a complete system consisting of a special self-leveling filter element, an auxiliary power unit, a control unit and a collection tank.
The ARGUS-Schlürkopf can be installed in 4" wells for static extraction of LNAPL. Its main area of application is in parallel to another hydraulic method (dynamic phase-extraction). In this case the ARGUS-Schlürkopf is directly installed in the ex-traction well.
The ARGUS-Ölboje is suitable for shallow constructed shaft wells or basins. LNAPL is col-lected by a floating filter element at the water surface and directed into a collection container, which is located within the vicinity of the wells/basin. Using a level meter-controlled special pump the LNAPL is then directed through a hose into an external tank.
Advanatages of the system:
•An almost streak-free recovery of LNAPL
•Flexible adaptability to a variety of problems
•Realisation of increased production rates of up to 50l/h and depths of up to 40m
•Autonomous adjustment to groundwater fluctuations of up to 1.5m
•Limited control oriented input, simple control
•Low-maintenance due to simple and compact construction
•Possible usage in hazardous area without additonal modules
•Statically operated LNAPL extraction systems can alternatively be operated with photo-voltaic,
wind power or battery.
In combination with our LNAPL extraction installations we also incorporate soil-vapour extraction to support the mobilisation of semi-volatiles. As well as achieveing mobilization, a reduction in contamination potential is also achieved through the removal of semi-volatile components out of the oil phase.
The extraction systems satisfy the VbF (Class AI to AIII and B), TRbF, WHG and ATEX requirements.

Storage for hazardous substances
For highly viscosity phases (like tar oil phases) we use extraction controlled by electrodes.
