TASK™ Surfactant-Enhanced Aquifer Remediation

Our anionic surfactant formulations have the unique ability to selectively desorb and liberate sorbed petroleum hydrocarbons from soil and fractured bedrock surfaces allowing for their improved mass recovery and or improved treatment by other remediation techniques. Supported by nearly two decades of research and formulation testing at the University of Oklahoma, TASK™ addresses a wide range of applications related to hydrocarbon contamination, including:

  • In situ soil and groundwater remediation
  • Pump and treat enhancement
  • Groundwater recirculation
  • Direct Injection
  • Ex situ soil washing
  • Emergency spill clean-up
  • Equipment and tank cleaning
  • Sludge removal
  • Pipeline cleaning

Benefits

Our anionic biodegradable surfactants provide considerable advantages.

  • Dramatic reduction in cost
  • Minimal surfactant mass – usually 0.5 to 0.9 weight percent
  • 1 to 1.4 pore volumes for up to 95% mass removal
  • No creation of a stable-emulsion, which dramatically reduces treatment costs – the oil separates from the water in a holding tank in less than 30 minutes
  • Easy to handle waste stream
  • Any surfactants remaining in the subsurface are easily biodegradable
  • Optimization gives lowest IFT, best recovery
