Original ORC and ORC Advanced Filter Socks/Canisters
Product
When Oxygen Release Compound (ORC®) was first commercialized some 15 years ago, it was designed to be emplaced into groundwater wells using Regenesis ORC Filter Socks (filter socks). Filter socks are permeable, fabric sleeves filled with pure ORC or ORC Advanced® material. Each filter sock is inserted into a colored, Naltex™ Flex-Guard for maximum durability. When hydrated, filter socks produce controlled-release, molecular oxygen for periods of up to 12 months on a single application. The abundant oxygen is then readily available to facilitate the proven and cost-effective, enhanced aerobic biodegradation process.
Purpose
Original ORC Filter Sock Schematic
Filter socks are designed to deliver controlled release oxygen into a specific well or treatment area with the purpose of creating a very localized but effective oxygenated zone where accelerated aerobic biodegradation can occur. Upon exhaustion of their oxygen supply (anywhere from 9-12 months) the socks can be removed and/or replaced.
Functionality
Filter socks are available in 2″, 4″ and 6″ diameters and can be replaced to restore the oxygen supply and maintain aerobic biodegradation as needed.
Filter socks are easily laced together using the pre-measured/ pre-cut rope that is supplied with each order (Figures 1, 2, 3 and 4). Filter socks can also be inserted into Regenesis, Application-Time-Saver Canisters (usually for deeper applications to avoid lodging the socks within the well) as required.
Construction
ORC and ORC Advanced Filter Socks are hand-made, permeable fabric sleeves, filled with pure ORC or more recently ORC Advanced. They are approximately 12” long and designed to fit 2”, 4” or 6” diameter wells.
Flex-Guard Durability
All sizes of Regenesis ORC and ORC Advanced Filter Socks include a factory installed, colored, Naltex™ Flex-Guard (green = 2”, yellow = 4” and orange = 6”). This component is designed to prevent rips or tears in the actual sock material assuring durability during the installation and removal process.
Application Considerations
- Existing aerobic or anaerobic conditions
- Contaminant type and mass
- Subsurface geology (distribution)
- Depth to groundwater
- Groundwater flow rates
- Competing electron acceptors (oxygen sinks)
- Free product (if present call Regenesis tech services to discuss options)
