Calcium Peroxide is an oxygen-generating compound used for enhanced aerobic bioremediation for treatment of a variety of contaminants, including petroleum hydrocarbons, some solvents, pesticides, and others. The use of calcium peroxide promotes increased contaminant removal and provides a sustained release of oxygen (up to 12 months) with no lock up or encapsulation.
The use of aerobic bioremediation technologies is most commonly at sites with petroleum hydrocarbons (BTEX, PAHs, TPH), fuel oxygenates and related compounds (MTBE, TBA). By providing a supplemental supply of oxygen to the subsurface through enhancements such as oxygen releasing compounds, the oxygen is made available to aerobic microorganisms in the unsaturated zone, saturated zone or both.
Enhanced aerobic biodegradation is suitable for sites with low to moderate levels of contamination. For sites with higher levels of petroleum hydrocarbons, it is often used in conjunction with a more powerful treatment method, such as in situ chemical oxidation (ISCO).
