The Dangle Scavenger is a unique separating and pumping system designed for the efficient active recovery of free phase hydrocarbon product from the surface water. The system is portable and is electrically safe for use in hazardous locations. 
The heart of the Dangle Scavenger is a floating oil/water separator which passes recovered oil to a remote pump and control assembly. Actual separation of oil or other hydrocarbons from water is effected by a mesh screen located in the floating buoy assembly. This screen is specially treated to pass oil and repel water.
  • Efficiently separates hydrocarbons from water in-situ using an oleophilic/hydrophobic membrane
  • Intake floats on the water surface
  • Automatically adjusts as water level fluctuates
  • Intrinsically safe explosion-proof design
  • Portable self-contained design
  • For quick and easy start up, ideal for emergency response
  • Durable construction for harsh field conditions
  • Recovers hydrocarbons to a sheen
  • Salt water and aromatic hydrocarbon models available
Trenches, manholes, small bodies of water, and wells 24" (61.5 cm) in diameter or larger, with fluctuating water table levels
