Super-Ox™

Oxygenation Equipment for Aerobic Bioremediation

Oxygen is a limiting factor for most aerobic bioremediation efforts. For example, to support the degradation of petroleum hydrocarbon compounds (BTEX, TPH, etc.), 3 times as much oxygen must be delivered for complete biological degradation. Therefore, effective aerobic bioremediation of a typical UST spill requires the delivery of large masses of dissolved oxygen (DO) to the subsurface. Unfortunately, most conventional remediation systems (i.e. air or oxygen sparging) cannot deliver enough DO to support complete degradation of the TPH mass that is present at a typical UST site.

Extracted groundwater is oxygenated (with 40-ppm levels of dissolved oxygen) and amended with nutrients and secondary acceptors by our Super-Ox™ equipment platform, which then injects this treatment water back into the subsurface. This consistent recirculation of oxygen-rich, nutrient-rich treatment water satisfies several critical requirements of all in situ bioremediation systems, including:

  • Constant delivery of dissolved oxygen, bioremediation products, other electron acceptors and nutrients to support accelerated biological degradation of target contaminants
  • Continuous movement of the injected treatment water through the contaminated soil and groundwater for optimum contact with contaminated groundwater and soil
  • Hydraulic plume control and focused flow of injected treatment water to specific zones within a plume area
