Strata FPRS – Free-Phase Recovery System

Strata FPRS is a Free-Phase Recovery System engineered for use in 2”, 4”, and larger wells and piezometers. The system features a perforated stainless-steel cage housing a selective absorbent sock with strong oleophilic and hydrophobic properties, designed to capture hydrocarbons including oil, diesel, gasoline, kerosene, and paraffin. The weighted cage ensures optimal submersion, while the fast-acting absorbent sock captures free-phase hydrocarbons within seconds. After recovery, the absorbent sock can be easily removed and safely disposed of, enabling efficient, low-maintenance operation.

Key Features

• Designed for passive recovery of hydrocarbons in wells and piezometers (2” and 4”)
• Stainless-steel AISI 316 perforated cage for durability and corrosion resistance
• Weighted cage ensures optimal submersion in the hydrocarbon layer
• Easy-to-install system: simply insert the sock, secure it with the bottom screw, and lower into the well
• Selective absorbent sock with oleophilic and hydrophobic properties – targets hydrocarbons only
• Absorbent capacity: approx. 1 L (2”) or 3 L (4”) – retains 10–13× its weight in hydrocarbons*
• Quick action – begins absorbing free-phase hydrocarbons in seconds
• Kit includes 1 cage and 12 absorbent socks
• Replacement absorbent socks available in packs of 12
• Compliant with standard disposal practices after recovery

*Absorbent capacity varies depending on product type and temperature.

Applications

• Groundwater remediation – removal of hydrocarbons from monitoring wells and piezometers
• Spill response – targeted recovery of hydrocarbons from confined spaces
• Industrial sites and fuel storage areas – ongoing control of free-phase hydrocarbons
• Environmental cleanup projects – field-friendly solution for passive recovery
