Oxygen Release Substrate Sleeve

Provect-ORS Sleeve Provectus® Oxygen Release Substrate (ORS) is easily deployed via groundwater wells using the Provect-ORS Sleeve delivery system to stimulate aerobicbiodegradation of organic contaminants. In the subsurface, the ORS materials will react with water to release oxygen slowly for a period of 3 to 6 months: 2CaO2 + 2H2O → 2Ca(OH)2 + O2 When necessary, exhausted sleeves are replaced with new ones to continue treatment. Organic constituents amendable to aerobic biodegradation processes include: Petroleum Hydrocarbons Light polycyclic aromatic hydrocarbons (PAHs) BTEX Benefits: Three different ORS options depending on site specific conditions, remedial application and budget. Significant cost savings realized due to high oxygen release rate and lower price compared to alternatives. Contains nutrients and is pH-buffered to reduce self-encapsulation. Estimated longevity of 3 to 6 months. Substantial time savings in the field because the reusable ORS Sleeves (PVC or stainles
