FRS - Fuel Recycling System
-
FSI uses membrane filtration to separate water from hydrocarbons (fuels/solvents). By taking advantage of the fact that water forms beads in hydrocarbons (due to higher surface tension of water compared to hydrocarbons), a membrane with a properly designed pore size will separate water beads.
-
The Water Selective Membranes from FSI have an optimized pore size and surface properties that can resist high water breakthrough pressure to provide an exceptional water separation efficiency.
-
FSI's FRS systems (with processing capacities from 2 gallons to over 50 gallons per minute) are designed to remove debris and water from various fuels. The products have been used in the US Army, the US Navy, air-derivative gas turbines, and for waste fuel recovery from junk yards.

-
FSI's water-selective filter elements simplify the two-stage filtration and separation process into a one-stage process.
-
The approach makes use of cross-flow, which is a surface filtration technique that minimizes the build up of the membrane surface cake layer and eliminates the passage blockage encountered when depth filtering is subjected to dry conditions.
-
In addition, the filter element takes advantage of a spiral-wound membrane cartridge design that maximizes filtrate flow capacity for a given volume to facilitate high capacity applications.
