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.

Suitable Applications

  • Aviation fuels: commercial Jet A, Jet B, and Jet A-1, military JP-4, JP-5, and JP-8 with additives


  • Vehicle/commercial fuels: diesel, gasoline, and kerosene


  • Hydrocarbon solvent purification and recycling


  • Separation of emulsified water/fuel and water/solvent mixtures


  • Purification of oil refinery products
