• Modified cellulose-based filter chemically bonds specifically with hydrocarbons and other pollutants such as dissolved and dispersed oils from water.
• Instantaneous adsorption, more effective than activated carbon.
• Up to 90 percent of total hydrocarbons are removed in a single pass.
• For use in 20-inch Big Blue® filter housings.

The OAC-20BB, made from modified cellulose-based filter media, is processed into sheets and assembled into cartridges for use in standard 20” Big Blue® filter housings.

Features
• Instantaneous adsorption - up to 90 percent of total hydrocarbons removed in a single pass.
• High flow rates.
• Removed dissolved and dispersed oils.
• Low pressure drop.
• Media can hold 250-300 percent of its own weight, with no release of removed hydrocarbons.

Applications
• Gas and oil facilities
• Leisure/commercial shipping bilge water
• Surface water runoff (truck stops, airports, parking lots)
• Auto service stations
• Machine shops
• Industrial processes
• Factories and repair shops
• Car and truck washes

Installation
Certain applications may require pre-filtration

Change-Out Frequency
Change-out frequency will depend on the oil burden they have to handle. Because no appreciable increase in pressure drop is observed during service life, the filter must be changed when its adsorption capacity is exhausted.
