Full Description 

Hydrocarbon Filter for Oil Containment

All secondary containment systems must incorporate some type of drainage system to evacuate wastewater. The HFF Oil Stop Valve is a hydrocarbon filter ideal for this application. Each HFF is designed for site-specific oil containment applications and meets Federal SPCC mandates.


HFF flow rates vary by size of filter, vertical or horizontal mount and the head pressure. The HFF uses oil solidifying polymer technology to capture all organic hydrocarbons, including the most volatile organic compounds, such as sheen, gasoline, diesel, refined oils and more. Each HFF hydrocarbon filter is capable of processing wastewater at the pre-determined rate specified by the customer.

All HFF Oil Stop Valves come with a pre-filter to trap and eliminate unwanted sediment and debris before it gets to the main hydrocarbon filter, which extends the life of the filter

HFF Berm Drain Kit for Spill Containment Berms

For quick and easy draining of portable spill containment berms, use the HFF Berm Drain Kit. By design, these berms often capture rainwater while in use. If oil is present in the rainwater, it must be removed before draining or manually dewatering the containment area. The HFF Berm Drain Kit allows the safe drainage of rainwater from spill containment berms, by preventing the escape of hydrocarbons.
