Geotech Small Diameter Filter Scavenger

Overview

The Geotech Small Diameter Filter Scavenger™ is an active hydrocarbon recovery system capable of recovering a wide range of floating hydrocarbons from groundwater. The system is designed to fit into a 4" (10cm) well or larger.

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. 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.
