FRS - Fuel and Solvent Recycling System

Originating from the Advanced Fuel Filtration System (AFFS) designed for Navy shipboard applications to provide high quality marine diesel fuel for gas turbines and jet fuel for refueling, the FRS provides fuel output quality that meets the most stringent spec requirements.  

Solve Fuel and Solvent Filtration Problems!

FSI has developed innovative technologies to remove debris and free water from fossil fuels and hydrocarbon based solvents. These systems can handle fuel containing up to 5% emulsified or free water and they output clean fuel with less than 5 ppm water and 0.2 ppm suspended solids. Since the FRS system is surfactant resistant, it can also be used to process fuel containing additives (e.g. +100) without sacrificing performance. FRS systems exceed the performance specifications set forth in API 1581 for Small Fuel Recycling System PhotoCategory C, Category M, and Category M100 fuel filters.

Suitable Applications Include:

  • 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



Water Selective Membranes

  • Generates super clean fuel
  • Performance is not compromised by fuel additives
  • Performance is not affected by idle time or dried out filters
  • Reliable performance
  • Provides high/stable output over the life of the membrane

Fuel and Solvent Resistant Membrane

Compatible with most hydrocarbons, free oils, acids, and the expansive class of polar organic solvents used in many industrial plants, the membrane can operate at temperatures up to 170° F and is stable through a broad pH range from 2 to 13

Cross-Flow Filtration

Handles higher solids content and minimizes filter fouling

Spiral-Wound Membrane Cartridges

Much higher filter area packing ratio which reduces space occupied by at least 50% compared to a coalescing fuel filter

Portable System

Capable of operating from a standard 55 gallon drum at point of use

Automated Operation

  • Reduces maintenance
  • Monitors system performance automatically

Self-Contained Design

  • Easy to install
  • Simple operation

Surfactant resistant fuel recycling system

FSI's fuel and solvent recycling filtration systems employ a patented, advanced membrane separation technology to remove free water, emulsified water, and dirt from fuels and solvents. At the heart of these systems are FSI's proprietary fouling resistant Water-Selective Membranes. 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.

Filtration Solutions, Inc. offers the following standard fuel and solvent recycling filtration systems with automatic or manual controls. FSI also provides customized filtration systems and a high capacity modular design (shown below) to meet the specific needs of our customers.

In this systematic modular design, each module is a totally contained element cartridge with its own housing. Cartridge replacement is simple and easy, and there is no direct human contact with fuel or oil. The modular design allows the system to have a very flexible and customizable capacity. The schematic below shows FSI's modular design fuel filtration process. The membrane elements are each designed as totally contained filter cartridges, and are connected to the feed, permeate, and retentate lines through three quick-disconnect connections. Therefore, replacing a cartridge is a simple job, and no tools are needed.
