PERMEOX® Ultra Granular is a specially formulated calcium peroxide that provides prolonged oxygen release for enhanced aerobic bioremediation. PERMEOX® Ultra Granular contains at least 18% active oxygen and is available in granular form.
Studies have shown that PERMEOX® Ultra Granular releases more oxygen into the subsurface environment over extended periods as compared to other soil remediation products. PERMEOX® Ultra Granular can continually release oxygen for over 350 days, thus providing a useful and cost-effective tool for enhancing the aerobic bioremediation of petroleum hydrocarbons and some non-halogenated organics.
PERMEOX® Ultra Granular is formulated to contain ≥18% Active Oxygen (AO), a measure of how much oxygen is available to be released. This compares favorably to the AO levels found in typical calcium peroxide and magnesium peroxide based oxygen release products that are subject to lock up/encapsulation. This means that on a pound to pound basis, PERMEOX® Ultra Granular is able to deliver more oxygen.
PERMEOX® Ultra Granular reduces dust hazards and material handling issues in the field.
Typical Applications
- Direct injections in the plume (slurry)
- In a permeable reactive barrier (PRB)
- Broadcast in open pit/excavation post UST and soil removal
Benefits at a glance
- Microbes use organic carbon (COC/COI) and oxygen as a terminal electron acceptor
- Contains ≥18% active oxygen, which is higher than other grades of calcium peroxide
- Releases oxygen for up to one year, which is the longest oxygen release profile of similar products in the market
