Passive Hydrocarbon Recovery

ORS Filter Bucket™
Passive Hydrocarbon Recovery Skimmer

The ORS Filter Bucket™ is an independently floating passive hydrocarbon recovery skimmer that is equipped with a visual alarm to indicate when the bucket is full. The heart of the system is a floating cartridge that recovers product for storage in an integral 2-liter reservoir. Actual separation of product from water is carried out by a mesh screen located in the cartridge. This screen is specially treated to pass oil and repel water.
