  • the RF cleaning and sterilizing systems 100, 100a may be used to eliminate bacteria, viruses, and other pathogen from various types of fluids by subjecting the fluids to a variable frequency RF waveform. Additionally, the RF cleaning and sterilizing systems 100, 100a may be used to cleanse and sterilize items, including food items such as raw meat 212, by removing bacteria, viruses, and other pathogen from the surface of the items. Such items may be cleansed and sterilized by immersing the items in a fluid 206 that is subjected to a variable frequency RF waveform.
  • the RF cleaning and sterilizing systems 100, 100a can be used to cleanse and sterilize fluids and fluid reservoirs, themselves, including, but not limited to, water tanks (such as tank 200), water towers, residential potable water sources, pools, hot tubs or spas, wells and other types of potable water sources and reservoirs of any size.
  • water tanks such as tank 200
  • water towers residential potable water sources, pools, hot tubs or spas, wells and other types of potable water sources and reservoirs of any size.
  • Such a system can eliminate the use of chlorine in installations that traditionally use it to cleanse a fluid, such as the treatment of water on ships, in pools and in hot tubs. It should be noted that, in installations such as pools or hot tubs, emitters may be covered to avoid direct skin contact.
  • the controller 102 includes at least one processor or logic processing unit (LPU) 105 connected to one or more processor-readable memories 103 storing one or more sets of processor-readable instructions for controlling the output of the signal generator 104.

In such a situation, for example, the signal generator 104 may increase the frequency of the generated electromagnetic signal by an incremental value, such as, for example, 1 Hertz, 5 Hertz, 10 Hertz, or more, in sweeping between the minimum frequency and the maximum frequency. As such, in one exemplary embodiment, the signal generator 104 would perform a sweep of frequencies between 0 Hertz and 25 kiloHertz within 5 milliseconds or, if desired, a sweep of frequencies between 0 Hertz and 25 kiloHertz within 10 milliseconds.
  • the signals generated by the signal generator 104 may include waveforms of various shapes.
  • the signal generator 104 may generate electromagnetic waves in the form of sine-waves, square waves, saw-tooth waves, and other similar waveforms. Every bacteria has a specific resonance frequency that will destroy it.

  • the signal generator 104 may advantageously be placed close to, or proximate to, the emitter 106 to reduce the amount of electromagnetic waveform energy that is dissipated as a result of the resistive and inductive properties that may be inherent in the output connection(s) 1 10.
  • the signal generator 104 may include, or be coupled to, a signal amplifier 210, to increase the voltage and/or current of the electromagnetic wave that is transmitted to the emitter 106.
  • the amplifier can be used to adjust the power output from 0 to 110 Volts. This can be changed depending on the requirements of a particular application.
  • the signal amplifier 210 enhances and increases the signal to ensure a more efficient and targeted kill.
  • the frequency emitted by the emitters 106 kill the bacteria when the emitters are powered by the voltage. Rather, every bacteria has a specific resonance frequency that will destroy it.

  • the emitter 106 is an elongated structure having a length 112 that separates a first end 1 14 and a second end 1 16.
  • the length 112 of the emitter 106 may depend, at least in part, on the strength of the electromagnetic wave to be transmitted by the emitter 106.

  • the emitter length to sterilize and cleanse fluids by neutralizing and killing bacteria, viruses, and other pathogen is selected to be from 12 inches to and including 24 inches.
  • the width of the emitter 106 is about 50 mm.
  • the cross-sectional area of the emitter 106 may be substantially circular (e.g., circular, elliptical, oval) in shape.
  • the emitter 106 may be made from any suitable material that will transmit an electromagnetic wave 1 18 into the surrounding environment based on the electromagnetic wave received from the signal generator 104 via the output connection 1 10.
  • the materials that comprise the emitter 106 may further resist or prevent corrosion when immersed in water or other fluids.
  • emitter 106a has a cover made of a piece of PVC pipe 1100 enclosed at each end by a PVC endcap 11 10, 1 120. Additionally, a conductor 1 10c connected to the emitter 106a, through the cap 1 110, provides a signal connection between the emitter 106 and the signal generator 104 and/or signal amplifier 210. In one particular embodiment, the cover 1 100 between the two endcaps, 1110, 1120, is filled with stainless steel wool balls 1130, shown through the partial cut-away 1135 of the tube 1 100.
  • Emitter 106b has a casing formed by a tube of perforated stainless steel 1200, enclosed at each end by a stainless steel endcap 1210, 1220.
  • the conductor 110c passes through the endcap 1210 and is connected directly to the inside wall of the perforated stainless steel tube casing 1200 with a rivet 1215.
  • the cover 1200 between the two endcaps, 1210, 1220 is filled with stainless steel wool ballsl 130. Water or another fluid in which the emitter 106b is immersed, can pass through the perforations in the steel casing, and also through the steel wool balls, while being treated. This results in less resistance and restrictions in water flow, and to a more efficient treatment.
  • each emitter 106, 106a, 106b act as an “antenna” that emits certain desired frequencies (as described above) as a consequence of certain frequency signals being received on the conductor 1 10c from the signal generator 104.
  • the steel wool 1130 of the present embodiment acts as a reflector in the emitter, providing more surface area in the container and causing the frequencies to be emitted at other angles relative to the surface of the emitter 106a, 106b.
  • each curve of the rolled-up, stainless steel balls in the emitter reflects the signal at 90° from the surface of the steel wool, thus providing a multi-array of signals in all direction in the media to be treated.
  • each emitter is most important to its functioning, as the wavelength of the signal is dependent on the length of the “antenna” created.
  • the length of the emitter is important for establishing resonant frequencies.
  • the length 1 12 of each emitter is a minimum of 12 inches.
  • one or more connectors 1 11 can be provided between the emitter 106, 106a, 106b and the signal generator 104 and/or signal amplifier 210.
  • the conductor length 110c can be made to be short, and each of the lengths 1 10a and 1 10b can be customized for the placement locations of each emitter 106, 106a, 106b.
  • the connectors 1 1 1 can be omitted and a single conductor 110 can be used to connect each emitter 106, 106a, 106b to a signal generator 104 and/or signal amplifier 210.
  • strong magnets 1 130 such as neodymium rare earth magnets, are attached to each end cap 1110, 1120, 1210, 1220, of the emitters 106, 106a, 106b, to simplify attachment of the emitter 106, 106a, 106b, to a metal surface within a metal tank or reservoir. This simplifies the placement of the emitters 106, 106a, 106b and eliminates any need for welding of the emitters 106, 106a, 106b to a particular location.
  • the electromagnetic waves emitted by the emitters 106, 106a, 106b neutralize microscopic organisms by agitating the organism at a “resonance frequency” that results in the membrane of the organism tearing apart.
  • Various types of microscopic organism may have different “resonance frequencies.” Accordingly, by emitting waveforms that sweep through a range of frequencies, the emitters 106, 106a, 106b may be used to neutralize multiple different types of organisms.
  • the bacteria that caused Legionnaire’s disease may be neutralized by emitting a resonance frequency of between 3 kHz and 8 kHz.
  • bacteria, viruses, and other pathogen may have resonance frequencies greater than 8 kHz (e.g., up to 25 kHz) or less than 2 kHz. In general three to five sweeps of the frequency range at a sufficient power level by the emitters 106 may be sufficient to neutralize a significant number of bacteria, viruses, and other pathogen, and in some situations, may result in all such organisms within a treated volume of fluid being neutralized.
  • such technology may be used to sterilize and clean solid objects, such as food items, immersed in a fluid that is subject to the electromagnetic waves being emitted by the emitter 106.
  • the emitters 106 are made from graphite.

  • Biasing one emitter 106 to the plus potential of the descaling power supply 1820 and the other emitter 106 to the minus potential of the descaling power supply 1820 creates an electrolysis process that generates micro bubbles 1840 on the surface of one of the emitters 106.
  • hydrogen micro bubbles 1840 will form on the emitter 106 acting as the cathode (i.e., the emitter 106 biased to the negative potential of the descaling power supply 1820).

  • the reference emitter 256 can be used to measure the current and resistance between the reference emitter 256 and the emitter 106. See step 1856 of the process 1850. These measurements can be used by the controller 102 and/or the descaling control unit 1810 to determine when the scale 1830 has been removed from the emitter 106 that is generating the micro bubbles 1840. See step 1858 of the process 1850. Alternately, if desired, the controller 102 and/or control unit 1810 can be programmed to apply the potentials for a predetermined amount of time that is sufficient to remove the scale from the negatively biased emitter 106.
  • the polarities of the emitter pair can be swapped by the descaling control unit 1810, so that the emitter 106 that was formerly biased to the negative potential of the descaling power supply 1820 is now biased to the positive potential, and vice versa. See steps 1858 and 1860 of the process 1850. This permits micro bubbles to form on the other emitter 106, to remove the scale from that emitter 106, as well.
  • both emitters 106 Once both emitters 106 are free of scale, they can be reconnected to the sterilizing system control unit and can be operated as part of the sterilization systems described hereinabove.

  • the system 1800 and process 1850 provide an automatic way for cleaning the scale from the emitters 106 without the need for manual cleaning, and prevents the need for stopping the entire sterilization system for maintenance, by removing only two emitters from the sterilization process at a time.

Abstract

Sont divulgués des systèmes et des procédés de nettoyage et de stérilisation de fluides et d'autres matériaux. Dans un mode de réalisation, un ou plusieurs émetteurs sont immergés dans un fluide et émettent des ondes électromagnétiques ayant une fréquence variable. La fréquence des ondes électromagnétiques est balayée sur une plage de fréquences pour neutraliser les bactéries, les virus et d'autres pathogènes dans le fluide. Les émetteurs peuvent être immergés à l'intérieur d'un réservoir de fluide et/ou à l'intérieur d'un trajet fluidique fermé (par exemple, un tuyau). Les matières solides peuvent être stérilisées par immersion des matières solides dans le fluide d'un tel réservoir de fluide. Dans un autre mode de réalisation, des ondes électromagnétiques peuvent être appliquées à un ou plusieurs fils qui sont enroulés autour d'une paroi extérieure d'un tuyau. La fréquence des ondes électromagnétiques peut être modifiée dans une plage de fréquences, ce qui permet d'obtenir le nettoyage du tartre et d'autres matériaux depuis la paroi intérieure du tuyau.
