Abstract : Effort was made to examine all known mechanical techniques for killing, removing, or controlling microorganisms found in hydrocarbon fuels. The microorganisms of interest included bacteria and fungi which are known to live in water, in a water-fuel interface, and within the hydrocarbon fuel. A group of 20 microorganisms, representative of those found in aircraft fuel tanks and fuel storage tanks, were selected for use in the various experiments. A complete evaluation was made on the utilization of radio frequency (RF) irradiation and ultrafine mechanical filters. The sterility of treated fuel samples was established, the effect of each technique on the fuel and fuel additive properties determined, and the effect of the treated fuel on fuel tank sealants and O-rings investigated.
