The polymers are capable of encapsulating and capturing all organic hydrocarbons such as sheen, gasoline, transmission oil, diesel, refined oils, and more. The HFF allows water to flow through as it removes and captures hydrocarbons including most volatile organic compounds. In the event of a major release, the HFF automatically shuts off the flow to contain the hydrocarbons. Each HFF is designed for site-specific applications and can used to meet SPCC and IEEE Std. 980 requirements.

Benefits
• Filters all organic hydrocarbons to <5 ppm; most will be at non-detectable levels
• Removes sheen, gasoline, diesel, refined oils, and other volatile organic compounds
• Low maintenance required when used with a reusable pre-filter to catch debris, silt, paper, limbs, etc.
• Will not drip or leach out

Applications
• Storm drains
• Electrical substations
• Retention pound out-flows 
• Storm water run-off
• Contaminated cooling tower water
• Secondary containment vaults
• Oil-water separator out-falls
• Bulk storage tank farm rain water out-falls
• Portable spill containment berms
