A fuel recirculation and cleaning assembly comprising a planar surfaced support base, an upright support secured to the support base and a flange extending from support base to form an enclosed area around the planar surface. A filter assembly for separating water from fuel and trapping particulate matter is mounted to the upright support and a discharge pump is fluidly connected to the filter assembly discharge water separated from the fuel by the filter assembly to a water storage tank. A magnetic microbial decontamination device is secured to the upright support and fluidly connected to the filter assembly by a conduit to receive filtered fuel from an outlet of the filter assembly and pass the fuel through a magnetic field which destroys microbial residues in the fuel. A circulation pump is mounted on the support base and is fluidly connected to an outlet of said microbial decontamination device by conduit means to discharge treated fuel to a fuel storage tank. The operation of the assembly is controlled by a timer mechanism.
A fuel recirculation and cleaning assembly comprising a support base, a plurality of legs mounted to said support base, wheel means mounted to said legs allowing said support base to be transported, an upright support secured to said support base, a water separator and fuel filter assembly mounted to said upright support, a microbial decontamination device for destroying the cellular integrity of microorganisms carried by fuel secured to said upright support and fluidly connected to said water separator and fuel filter assembly by conduit means, a circulation pump mounted to said support base, said circulation pump being operated at a minimum flow rate of at least 250 GPH and being connected to an outlet of said microbial decontamination device by conduit means and a conduit leading from said circulation pump to a fuel storage tank and microprocessor controls including timer control means to start and stop said circulation pump.
A fuel recirculation and cleaning assembly for unmanned automatic cycling of fuel comprising a support base with a top planar surface, an upright support secured to said support base, a control box mounted to said upright support, said control box containing a microprocessor and circuit means which energizes and de-energizes a circulation pump at periodic times and senses pressure differentials in the conduits, a filter assembly for separating water from fuel and trapping particulate matter mounted to said upright support, means to fluidly connect said filter assembly to a fuel storage tank, means to discharge water separated from said fuel connected to said filter assembly, a magnetic microbial decontamination device secured to said upright support and fluidly connected to said filter assembly by conduit means, a circulation pump mounted to said support base, said circulation pump having a flow rate in excess of 250 GPH being connected to an outlet of said microbial decontamination device by conduit means to transport fuel from said fuel storage tank, a conduit leading from said circulation pump to a fuel storage tank carrying cleaned fuel back to said fuel storage tank and timer control means to start and stop said circulation pump in a predetermined cycle.
A method of automatically cleaning and recirculating stored petroleum based fuel comprising the steps of:
