ABSTRACT:
An apparatus and method for providing a charged fluid and for creating an electret from a receptor, such as roll mill polymer film, whereby the electret will have the highest possible static electrical charge within the physical limits of the receptor. The apparatus according to the present invention includes, inter alia, a housing, a plurality of equidistantly spaced electrodes, each electrode having optimum geometry, location and electrification voltage so as to provide a maximum, uniform electric field therebetween, the electrodes collectively forming a charger grid within the housing, and a source of flowing gaseous fluid entering into the housing, the flowing gaseous fluid ionizing at the charger grid, resulting in an optimized corona within the housing. The method according to the present invention induces an optimal corona, defined as a maximum possible electric field having a strength that is near the spark over voltage, in a flowing gaseous fluid by passing the gaseous fluid past the charger grid. The resulting ionization of the flowing gaseous fluid is then utilized to transport electrical charge to a device such as an electrostatic filter and aerosol mixer or the surface of a receptor. The apparatus and method are suitable for the antibacterialogical and antiviral treatment of biologic substances, such as animal organisms, plant organisms, blood and tissue, and also other substances, such as waste water.
