Oxygen Injection System for Groundwater Bioremediation

The Matrix Oxygen Injection System produces pure oxygen from compressed air for pulse injection into groundwater at controlled rates, resulting in high transfer efficiency to groundwater and dissolved oxygen saturation levels up to 40 mg/L. Because the resultant oxygen supply is greater than the total oxygen demand, this system creates optimal conditions for native bacteria to break down petroleum hydrocarbons, gasoline oxygenates and solvents, for faster and more efficient site cleanup. This cost effective system has shown excellent results with MTBE and TBA, with a history of successful site closures over the past 14 years.

This technology is suitable for many geologic conditions including fractured bedrock. Hazardous vapors are not generated making the process ideal for shallow groundwater conditions and in close proximity to receptors. Oxygen injection is used for plume treatment and in biobarriers. Unlike other oxygen supplying techniques, it treats the entire plume by dispersing and dissolving oxygen gas into the formation. It is not diffusion limited and the oxygen supply is sustainable which prevents a return to reducing conditions.

• Matrix Oxygen Injection Systems have been successfully applied at more than 250 sites, and are used by major oil companies, power companies, the U.S. Military and state regulatory agencies.

• Matrix's oxygen injection technology provides a solution for the cleanup of petroleum leaks from underground storage tanks (LUST). LUST cleanup is an environmental program administered by EPA as part of the 2009 Recovery Act. These EPA programs will protect and promote both “green” jobs and a healthier environment.

• Matrix Oxygen Injection Systems are available for purchase, rental or lease and include a license to operate under U.S. Patent No. 5,874,001. Full training is provided.

• This robust, low maintenance system is engineering for a safe and reliable supply of oxygen on-site, so you have no concerns about oxygen storage or transport. U.L. labeling of systems available.

• Sustainable high levels of dissolved oxygen maintain aerobic conditions and prevent contaminant rebound. MTBE biodegrades without TBA accumulation.

• This system disperses and dissolves oxygen in the formation with control of radius of influence and oxygen mass transfer.
