In-Situ& Ex-Situ Advanced Oxidation Technologies for Site Remediation

water-pump-deviceThe HiPOx process is classified as an Advanced Oxidation Process (AOP), which utilizes ozone and hydrogen peroxide to form hydroxyl radicals. AOP processes, also known as Peroxone chemistry, using ozone and hydrogen peroxide to create hydroxyl radicals are well documented. Hydroxyl radicals are second only to fluorine in their oxidizing potential. Hydroxyl radicals react very rapidly to oxidize contaminants to non-hazardous compounds including carbon dioxide (CO2) and water (H2O).

APTwater’s PulseOx® process is an in-situ chemical oxidation (ISCO) technology for the remediation of contaminated soil and groundwater. PulseOx systems offer 35-50% more powerful chemical oxida­tion, and up to 1-billion times faster reac­tion kinetics than conventional air-sparge or ozone-sparge remediation systems. PulseOx systems deliver greater value through faster cleanup and closure of en­vironmental remediation sites.

Key Features of In-Situ & Ex-Situ Oxidation

  • Powerful Hydroxyl Radical Chemistry
  • No Process Residuals
  • Rapid Clean-up: 6-12 months typical
  • Fast & Easy Deployment
  • Easy Integrations with Other Processes
  • Fully-Automated 24-7-365 Operation
  • Process Safety
  • Cost-Effectiveness

PulseOx Applications

The PulseOx process is ideal for the in-situ remediation of a wide range of dis­solved contaminants, including:

  • Petroleum Hydrocarbons (BTEX, TPHg, Diesel, Aviation Fuel, etc.)
  • Chlorinated Solvents (PCE, TCE, DCE, VC, and most intermediaries)
  • Solvent Stabilizers (1,4-dioxane)
  • Fuel Oxygenates and Byproducts (MTBE, TBA, etc.)
  • PAHs (naphthalene and other aromatic compounds)
  • Creosols / Phenols (creosote and many phenolic compounds)
  • NAPL destruction in source areas or vadose zone soils
  • Other Organics (naturally occurring organic materials, tannins, etc.)

Nebraska Ordnance Plant, Mead, NE Chlorinated Solvents Remediation—Ex-situ

nebraska-ordnance-plantAPTwater installed a high capacity HiPOx® system for the remediation of TCE contaminated groundwater at a former military installation near Mead, Nebraska. The system treats 575+ gpm of groundwater with TCE concentrations as high as 5,800 ppb. HiP0x technology was selected based on its up to 71% lower annual operating cost versus the existing

air-stripping and vapor-phase carbon treatment system. The HiPOx system achieves >99.8% removal of TCE before effluent is sent to the existing carbon system for final polishing. Treated water from the remediation system meets all public health requirements and is pumped over 1 mile away for irrigation and surface water discharge.
