DNAPL and LNAPL removal by solvent or surfactant enhanced aquifer remediation (SEAR)

  • Surfactant or alcohol injection enhances the dissolution of chlorinated hydrocarbons, PAHs, DNAPLs and LNAPLs in water from a few ppm to 10,000 - 50,000 ppm
  • Organics recovered in two weeks equaled eight years of normal pump and treat
  • MPPE proven as the ideal separation technology for these extremely high concentrations in surfactants/alcohol water mixtures
  • Surfactant/solvent consumption savings as MPPE enables recirculation and recovery

DNAPL/LNAPL projects were MPPE was applied in
