Abstract: Apparatus, systems and methods for subjecting biological contaminated liquid fuels and/or liquids to an oscillating electric field for an extended duration within a treatment vessel that has a defined cavity having an insulating fill material encasing a number of insulating flow tubes each having at least one conductive body therein. The defined cavity also has one or more reservoirs in communication with the insulating flow tubes. An oscillating electric field is generated within the insulating flow tubes and reservoirs, whereby a biologically contaminated liquid fuel and/or lubricant is subjected to this oscillating electric field for an extended time to inhibit proliferation of these biological contaminants within the liquid fuels and/or lubricants.

Abstract: Electrostatic filters, systems and methods having separate positively and negatively charged filter elements within electrically isolated filter tanks for electrostatically filtering particles from a fluid flow. Both positive charged connections biased to earth ground and negative charged connections biased to earth ground are made to the respective positive and negative charged filter elements, along with triboelectric induced charge accumulations from the fluid flow, for separating charged particles within the fluid flowing parallel through these oppositely charged filter elements. Variable resistors of a power supply connected to such filters, systems and methods provide for controlling and adjusting for any undesired voltage excesses and/or shortfalls within these filter tanks so that the fluid flowing exiting these filter tanks is unbiased to generate a filtered fluid having balanced electrostatic charges.
