Geotech Small Diameter Filter Scavenger™
The Geotech Small Diameter Filter Scavenger™, is a hydrocarbon recovery system capable of recovering a wide range of floating hydrocarbons from groundwater wells. The system is designed to fit into a 4" diameter (10cm) well or larger.
- Unique design makes product recovery more efficient than total fluids
- Highly efficient water-free product recovery
- Ideal for wells with static fluid levels down to 150' (46.1 m)
- Operates reliably in fluctuating water levels
- Uses oleophilic/hydrophobic membrane to separate and recover hydrocarbons from water table
- 100% portable for use well to well or site to site
- Custom applications available to meet your site specific conditions
- Fully automated operation
- Complemented results with use of water table depression pump (dual pumping system)
- Explosion Proof controls available for use in hazardous environments (Class I, Div 1)

| Options | Geotech Environmental Control Module with NEMA 4X enclosure, in-line water table depression pump, tank-full shut-off, spare parts kit (fuses, bulbs, union), winch & shroud, XP NEMA 7 controls. |
| The Geotech Small Diameter Filter Scavenger™ (SDFS) uses a floating intake cartridge which follows the fluctuations of the water table up to 12" (30cm). Systems capable of handling 3' (1 m) of water table fluctuations are available upon request. |
 |
| Typical configuration of a Small Diameter Filter Scavenger™ with water table depression pump system |
| The intake cartridge consists of a float and a specially treated oleophilic/hydrophobic membrane. This unique membrane allows hydrocarbons to enter the cartridge while simultaneously repelling water. The system reduces the thickness of hydrocarbon layers down to a sheen. It can be operated either alone or in conjunction with a water table depression pump. |
