Ex-Situ Chemical Oxidation of Soil & Hazardous Waste

 
Technology Background

ART employs two types of ex-situ soil/sediment chemical oxidation processes:

1) Saturated Soil Contacting - typical contaminant reduction efficiency in range of 50-80%

2) Soil Oxidation in Slurry Reactors - contaminant reduction greater than 90% up to 99% achievable depending on type of contamination and soil/sediment matrix.

Chemical oxidation can be potentially effective for a wide range of organic compounds found in soil and hazardous waste, including but not limited to:

  • VOC's (Benzene, Toluene, BETX, Methylene Chloride and others),
  • SVOC's & halogenated compounds (TCA, TCE, PCE, Vinyl Chloride, PCB, Dioxin, TNT, DNT)
  • PFOA and PFOS
  • DDT, HCH, Chlorinated Pesticides and others.
