The disclosure relates generally to ultraviolet radiation, and more particularly, to disinfecting a flowing fluid using ultraviolet radiation.
Sterilization systems for water, air, and surfaces are known in the art and have a successful history of development. The main feature of these sterilization systems is a source of ultraviolet (UV) radiation having wavelength(s) that are close to the absorption peaks of biologically significant molecules of DNA and proteins. The system can sterilize a medium to a safe condition as long as the power of the ultraviolet source and an exposure time are sufficient to destroy the internal biomolecular structure of the bacteria, viruses, protozoa and germs.
Known ultraviolet sterilization systems use mercury lamps or deep UV light emitting diodes as a source of ultraviolet radiation. Low-pressure and medium-pressure mercury lamps provide a linear spectrum of radiation with some lines, which wavelengths are in the relative vicinity to a DNA absorption line. A low-pressure mercury lamp with a main peak at 253.4 nanometers (nm) is often used in low-consumption residential water and air purification systems. Medium-pressure mercury lamps with a higher radiation power have a multi-peak radiation spectrum and are often used in municipal systems with medium and high water consumption.
However, the use of mercury lamps has significant drawbacks. For example, mercury lamps are fragile and bulky. Also, mercury is an extremely dangerous element, which implies serious limitations on applications of the mercury-based water purification systems. In particular, mercury lamps are not practical for use in transport and individual systems. Furthermore, a typical operating lifetime of a mercury lamp is less than 10,000 hours. An additional limitation is an inability to adjust or control a radiation spectrum of the mercury lamp. To this extent, the peaks of a mercury lamp do not exactly coincide with the absorption peaks of DNA and proteins, thereby decreasing the sterilization efficiency.
Some approaches have sought to minimize one or more drawbacks of mercury lamp-based sterilization. For example, one approach proposes a handheld ultraviolet water purification system based on a miniature mercury lamp. The design is targeted to overcome the size and portability drawbacks of traditional mercury lamp-based ultraviolet purifying systems. Nevertheless, the need for contact and even steering the sterilizing water with a fragile quartz sleeve with the mercury lamp inside makes the device dangerous for residential applications and not appropriate for transport, field, and portable application.
Aspects of the invention provide a solution that uses ultraviolet radiation to irradiate a flowing fluid (e.g., a liquid or gas) through a channel. An example of the fluid is water, but it is understood that the fluid can be any type of fluid that would need disinfection from harmful microorganisms, including bacteria, viruses, germs, parasitic agents, pathogens, and other contaminants. Ultraviolet radiation sources can be located within the channel in order to direct ultraviolet radiation towards the flowing fluid and/or the interior of the channel. A valve can be located adjacent to the channel to control the flow rate of the fluid. A control system can control and adjust the ultraviolet radiation generated by the ultraviolet radiation sources based on the flow rate and a user input component can receive a user input for the control system to adjust the ultraviolet radiation generated by the ultraviolet radiation sources. The ultraviolet radiation sources, the control system, the user input component, and any other components that require electricity can receive power from a rechargeable power supply. An electrical generator located within the channel can convert energy from the fluid flowing through the channel into electricity for charging the rechargeable power supply.

The illustrative aspects of the invention are designed to solve one or more of the problems herein described and/or one or more other problems not discussed.
These and other features of the disclosure will be more readily understood from the following detailed description of the various aspects of the invention taken in conjunction with the accompanying drawings that depict various aspects of the invention.
It is noted that the drawings may not be to scale. The drawings are intended to depict only typical aspects of the invention, and therefore should not be considered as limiting the scope of the invention. In the drawings, like numbering represents like elements between the drawings.
As indicated above, aspects of the invention provide a solution that uses ultraviolet radiation to irradiate a flowing fluid (e.g., a liquid or gas) through a channel. An example of the fluid is water or another potable liquid, but it is understood that the fluid can be any type of fluid that would need disinfection from harmful microorganisms, including bacteria, viruses, germs, parasitic agents, pathogens, and other contaminants. Ultraviolet radiation sources can be located within the channel in order to direct ultraviolet radiation towards the flowing fluid and/or the interior of the channel. A valve can be located adjacent to the channel to control the flow rate of the fluid. A control system can control and adjust the ultraviolet radiation generated by the ultraviolet radiation sources based on the flow rate and a user input component can receive a user input for the control system to adjust the ultraviolet radiation generated by the ultraviolet radiation sources. The ultraviolet radiation sources, the control system, the user input component, and any other components that require electricity can receive power from a rechargeable power supply. An electrical generator located within the channel can convert energy from the fluid flowing through the channel into electricity for charging the rechargeable power supply.
As used herein, ultraviolet irradiation of a fluid and/or the channel(s) containing the fluid can entail sanitizing, disinfecting, and/or sterilizing. Sanitizing generally means reducing the number of bacterial contaminants to a predetermined safe level. Disinfecting generally means destroying pathogenic and other types of microorganisms, while sterilizing can be more extensive in that it kills all microbial forms and/or include destroying the ability of the microbial forms to reproduce. While aspects of the invention are described in conjunction with such treatment of a fluid using ultraviolet radiation, it is understood that embodiments of the invention are not limited to ultraviolet radiation and can include other types of electromagnetic radiation, such as visible light and infrared radiation, and/or other applications.
Ultraviolet radiation, which can be used interchangeably with ultraviolet light, means electromagnetic radiation having a wavelength ranging from approximately 10 nm to approximately 400 nm. Within this range, there is ultraviolet-A (UV-A) electromagnetic radiation having a wavelength ranging from approximately 315 nm to approximately 400 nm, ultraviolet-B (UV-B) electromagnetic radiation having a wavelength ranging from approximately 280 nm to approximately 315 nm, and ultraviolet-C (UV-C) electromagnetic radiation having a wavelength ranging from approximately 100 nm to approximately 280 nm.
Generally, ultraviolet radiation, and in particular, UV-B radiation and UV-C radiation is “germicidal,” i.e., it deactivates the DNA of bacteria, viruses and other pathogens, and thus, destroys their ability to multiply and cause disease. This effectively results in sterilization of the microorganisms. Specifically, UV-B radiation and UV-C radiation cause damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of these bonds prevents the DNA from being “unzipped” for replication, and the organism is neither able to produce molecules essential for life process, nor is it able to reproduce. In fact, when an organism is unable to produce these essential molecules or is unable to replicate, it dies. Ultraviolet radiation with a wavelength of approximately between about 250 nm to about 290 nm provides the highest germicidal effectiveness, while ultraviolet radiation between about 260 nm to about 310 nm is sufficient for providing overall germicidal effectiveness, and ultraviolet radiation between 260 nm to 270 nm is a preferred range for facilitating disinfection, sterilization of potable liquids. While susceptibility to ultraviolet radiation varies, exposure to ultraviolet energy in the above range for about 20 to about 34 milliwatt-seconds/cm2 is adequate to deactivate approximately 99 percent of the pathogens.
As used herein, a layer is a transparent layer when the layer allows at least ten percent of radiation having a target wavelength, which is radiated at a normal incidence to an interface of the layer, to pass there through. Furthermore, as used herein, a layer is a reflective layer when the layer reflects at least ten percent of radiation having a target wavelength, which is radiated at a normal incidence to an interface of the layer. In an embodiment, the target wavelength of the radiation corresponds to a wavelength of radiation emitted or sensed (e.g., peak wavelength+/−five nanometers) by an active region of an optoelectronic device during operation of the device. For a given layer, the wavelength can be measured in a material of consideration and can depend on a refractive index of the material.
As used herein, unless otherwise noted, the term “set” means one or more (i.e., at least one) and the phrase “any solution” means any now known or later developed solution. The singular forms “a,” “an,” and “the” include the plural forms as well, unless the context clearly indicates otherwise. Additionally, the terms “comprises,” “includes,” “has,” and related forms of each, when used in this specification, specify the presence of stated features, but do not preclude the presence or addition of one or more other features and/or groups thereof.
Turning to the drawings,

In an embodiment, the set of ultraviolet radiation sources 22 are secured by connecting components, such as screws, within the channel, so that the ultraviolet radiation sources 22 can be easily replaced. Although the set of ultraviolet radiation sources 22 are shown located on only one side of the channel 14, it is understood that the set ultraviolet radiation sources 22 can be located anywhere in one or more locations of the channel. As shown, the set of ultraviolet radiation sources 22 are connected to the rechargeable power supply component 20. As discussed herein, the set of ultraviolet radiation sources 22 can be powered by any mechanism, in addition to or instead of, the rechargeable power supply component 20, such as a household power outlet.

In an embodiment, the set of ultraviolet radiation sources 22 can include a set of LEDs manufactured with one or more layers of materials selected from the group-III nitride material system (e.g., AlxInyGa1-x-yN, where 0≤x, y≤1, and x+y≤1 and/or alloys thereof). Additionally, the set of ultraviolet radiation sources can comprise one or more additional components (e.g., a wave guiding structure, a component for relocating and/or redirecting ultraviolet radiation emitter(s), etc.) to direct and/or deliver the emitted radiation to a particular location/area, in a particular direction, in a particular pattern, and/or the like. Illustrative wave guiding structures can include, but are not limited to, a wave guide, a plurality of ultraviolet fibers, each of which terminates at an opening, a diffuser, and/or the like.
The set of radiation sources 22 can include ultraviolet radiation sources that operate in the ultraviolet wavelength range (e.g., 10 nm to 400 nm). In an embodiment, the set of radiation sources 22 can operate to emit radiation having a peak wavelength in or immediately adjacent to the UV-C wavelength range and are referred to as “UV-C sources” herein. For example, the set of radiation sources 22 can emit radiation having a peak wavelength in a range of approximately 250 nm to approximately 290 nm. In a more specific embodiment, the set of radiation sources 22 can operate in the wavelength range of approximately 270 nm to approximately 290 nm. Although
In an embodiment, each of the ultraviolet radiation sources in the set of radiation sources 22 can operate at a different peak wavelength (λ). In an embodiment, each of the ultraviolet radiation sources in the set of radiation sources 22 can irradiate a different direction within the channel 14 at different peak wavelengths. In another embodiment, the set of radiation sources 22 can all irradiate different directions within the channel 14 but with relatively uniform radiation. In another embodiment, more than one ultraviolet radiation source in the set of ultraviolet radiation sources 22 can irradiate a single direction within the channel 14 but each ultraviolet radiation source can operate at a different wavelength and/or intensity. In an embodiment, a portion of set of ultraviolet radiation sources 22 can operate in the UV-C range, while another portion of the set of ultraviolet radiation sources 22 can operate in the UV-A range.

In an embodiment, the control system 26 can adjust the ultraviolet radiation and/or the flow rate of the fluid 12 to achieve a target disinfection of the fluid 12 and/or the interior of the channel 14. In an embodiment, the set of ultraviolet radiation sources 22 can be periodically turned on by the control system 26 to ensure that the interior of the channel 14 is disinfected prior to the fluid 12 flowing through the channel 14. Although not shown, the channel 14 can include an air compression module for allowing air to blow through the channel to remove any fluid from the channel 14. Regardless, in an embodiment, the control system 26 can control and adjust the ultraviolet radiation and/or the flow rate of the fluid 12 based on a set of current conditions such as the flow rate of the fluid 12, a transparency of the fluid 12, a presence (or lack of) fluid 12 within the channel 14, the temperature of the fluid 12, images of the fluid 12 and/or interior of the channel 14, a fluorescence emissivity generated from the fluid 12, and/or the like.

In an embodiment, the external interface I/O component 28 can include a speaker for providing an alarm (e.g., an auditory signal), e.g., for signaling that ultraviolet radiation is being generated or that an ultraviolet treatment has finished.
The computer system 520 is shown including a processing component 522 (e.g., one or more processors), a storage component 524 (e.g., a storage hierarchy), an input/output (I/O) component 526 (e.g., one or more I/O interfaces and/or devices), and a communications pathway 528. In general, the processing component 522 executes program code, such as the analysis program 530, which is at least partially fixed in the storage component 524. While executing program code, the processing component 522 can process data, which can result in reading and/or writing transformed data from/to the storage component 524 and/or the I/O component 526 for further processing.

To this extent, in other embodiments, the functionality provided by the computer system 520 and the analysis program 530 can be at least partially be implemented by one or more computing devices that include any combination of general and/or specific purpose hardware with or without program code. In each embodiment, the hardware and program code, if included, can be created using standard engineering and programming techniques, respectively. In another embodiment, the control unit can be implemented without any computing device, e.g., using a closed loop circuit implementing a feedback control loop in which the outputs of one or more sensors are used as inputs to control the operation of a treatment. Illustrative aspects of the invention are further described in conjunction with the computer system 520. However, it is understood that the functionality described in conjunction therewith can be implemented by any type of monitoring and/or control system.
