Definitions

  • the present disclosure relates to janitorial systems.
  • Water intended for potable use may contain disease-causing organisms, or pathogens, which can originate from the source of the water, from resistance to water treatment techniques, from improper or ineffectual water treatment techniques, or so forth.
  • Pathogens include various types of bacteria, viruses, protozoan parasites, and other organisms.
  • a disinfectant such as chlorine
  • disinfection practices can be ineffectual because certain microbial pathogens, such as Cryptosporidium, are highly resistant to traditional disinfection practices.
  • disinfectants themselves can react with naturally-occurring materials in the water to form byproducts, such as trihalomethanes and haloacetic acids, which may pose health risks.
  • Oxidation reduction potential can be used for water system monitoring to reflect the antimicrobial potential of the water, without regard to the water quality, with the benefit of a single-value measure of the disinfection potential, showing the activity of the disinfectant rather than the applied dose.
  • aspects of this disclosure are directed to a system that generates an aqueous ozone solution for cleaning purposes and purified water for consumption.
  • the system includes an enclosure with openings for a water inlet and an aqueous ozone solution outlet.
  • One or more ozone generators are disposed within the enclosure.
  • a fluid mixer may also be disposed within the enclosure, in between the water inlet and the aqueous ozone solution outlet.
  • the system further includes a janitorial fill station with a first faucet fluidically coupled to a first output of the splitter and configured to dispense a first portion of the aqueous ozone solution, a carbon filter fluidically coupled to a second output of the splitter and configured to reduce an ozone concentration of a second portion of the aqueous ozone solution to produce purified water for consumption, and a second faucet fluidically coupled to the carbon filter and configured to dispense the purified water.
  • a janitorial fill station with a first faucet fluidically coupled to a first output of the splitter and configured to dispense a first portion of the aqueous ozone solution, a carbon filter fluidically coupled to a second output of the splitter and configured to reduce an ozone concentration of a second portion of the aqueous ozone solution to produce purified water for consumption, and a second faucet fluidically coupled to the carbon filter and configured to dispense the purified water.
  • FIG. 3 is schematic illustration of the system, in accordance with one or more embodiments of this disclosure.
  • FIG. 4 is a perspective view of a spray gun of the system, in accordance with one or more embodiments of this disclosure.
  • FIG. 5 is a perspective view of a portable electric sprayer of the system, in accordance with one or more embodiments of this disclosure.
  • FIG. 6 is a perspective view of a spray bottle of the system, in accordance with one or more embodiments of this disclosure.
  • An ORP value can be used for water system monitoring to reflect the antimicrobial potential of a given sample of water.
  • ORP is measured in millivolts (mV), with typically no correction for solution temperature, where a positive voltage shows a solution attracting electrons (e.g., an oxidizing agent). For instance, chlorinated water will show a positive ORP value whereas sodium sulfite (a reducing agent) loses electrons and will show a negative ORP value. Similar to pH, ORP is not a measurement of concentration directly, but rather of activity level. In a solution of only one active component, ORP indicates concentration.
  • the World Health Organization (WHO) adopted an ORP standard for drinking water disinfection of 650 millivolts.
  • the WHO stated that when the oxidation-reduction potential in a body of water measures 650 (about 2/3 of a volt), the sanitizer in the water is active enough to destroy harmful organisms almost instantaneously.
  • E. coli, Salmonella, Listeria, and Staph pathogens have survival times of under 30 seconds when the ORP is above 650 mV, compared against >300 seconds when it is below 485 mV.
  • An example ORP sensor uses a small platinum surface to accumulate charge without reacting chemically. That charge is measured relative to the solution, so the solution "ground” voltage comes from the reference junction.
  • an ORP probe can be considered a millivolt meter, measuring the voltage across a circuit formed by a reference electrode constructed of silver wire (in effect, the negative pole of the circuit), and a measuring electrode constructed of a platinum band (the positive pole), with the water in-between.
  • ozone an oxidizing agent approved for drinking water treatment by the U.S. Environmental Protection Agency.
  • ozone is one of the strongest disinfectants approved for potable water treatment capable of inactivating bacteria, viruses, Giardia, and Cryptosporidium.
  • the disclosed system may be configured to output an aqueous ozone solution including water with an ORP of about 600 mV to about 1000 mV, with particular embodiments configured to output water having an ORP of about 700 mV to about 900 mV to provide pathogenic control.

  • the securable lid/cover 204 may be secured to the enclosure 202 by a hinge on one side and a latch or fastener on an opposing side.
  • FIG. 2 illustrates the AOS supply unit 200 with the lid/cover 204 opened or removed from the enclosure 202, in accordance with one or more embodiments of this disclosure.
  • the enclosure 202 includes one or more air intake ports 220.

  • the ozone generators 206 may be fluidically coupled to the one or more air intake ports 220 by one or more tubes 216 (e.g., flexible tubing, pipes, etc.).

  • the ozone generators 206 may include other methods and systems for generating ozone, including but not limited to, electrochemical cells configured to generate ozone from water by placing an anode and a cathode in contact with opposite sides of a proton exchange membrane (PEM), and supplying power to the cell, whereby water flowing over the surface of the anode breaks down into hydrogen atoms and oxygen atoms that assemble to form O3 (ozone).
  • PEM proton exchange membrane
  • the AOS supply unit 200 may include a fluid mixer 230 fluidically coupled to the one or more ozone generators 206 by one or more tubes 218 (e.g., flexible tubing, pipes, etc.) for transferring ozone from the one or more ozone generators 206 to the fluid mixer 230.
  • the fluid mixer 230 is disposed within the enclosure 202 between a water inlet 226 and an AOS outlet 228.
  • the fluid mixer 230 may be configured to introduce/inject ozone generated by the ozone generators 206 into water flowing between the water inlet 226 and the AOS outlet 228. In this manner, the fluid mixer 230 mixes the ozone from the ozone generators 206 with the water flowing into the AOS supply unit 200 to produce an aqueous ozone solution that is output via the AOS outlet 228.
  • the aqueous ozone solution may pass through an in-line mixer coupled between the venturi and the outlet.
  • the fluid mixer 230 may include a combination of a venturi and an in-line mixer, or another type of multi-port coupler with an in-line mixer.
  • the in-line mixer can facilitate further breaking or mixing of ozone bubbles already introduced to the water to generate a mixture (or solution) of water and substantially uniform-sized ozone bubbles.
  • the small uniform-size ozone bubbles can adhere to each other to lower the surface tension of the aqueous ozone solution.
  • the in-line mixer has an internal diameter that equals an internal diameter of the output port of the venturi to which the in-line mixer is coupled. The same internal diameter can provide an uninterrupted transition of the fluid flowing from the venturi to the in-line mixer, such as to maintain a vortex action or mixing action of the water and the ozone bubbles.
  • the in-line mixer also provides increased contact time between the water and ozone bubbles and can facilitate preparation of uniform ozone bubble size.
  • the in-line mixer has a length of about two inches downstream from the venturi, which can allow sufficient time for the velocity of the vortex action caused by the pressure differential of the venturi to crush the gaseous bubbles entrained in the solution into uniformed size bubbles.
  • the in-line mixer can also reintroduce undissolved gas back into the solution resulting in increased efficiency as well as reduced off-gas at the point of application.
  • the in-line mixer can include multiple chambers through which the aqueous ozone solution flows. The size of the chambers can be determined based on the water flow (e.g., throughput), gas mixing, and desired time exposure.
  • the AOS supply unit 200 may further include or may be coupled with a flow switch 222 that is configured to detect water flow through the AOS supply unit 200/system 100.
  • the flow switch 222 may be disposed within the enclosure 202.
  • the flow switch 222 may be fluidically coupled in line with the fluid mixer 230, between the water inlet 226 and the AOS outlet 228.
  • the water inlet 226 and the AOS outlet 228 are located on opposite sides of the enclosure 202, allowing for a linear (e.g., horizontal) flow path through the enclosure 202.
  • the flow switch 222 may be external to the enclosure 202 and/or at a distance from the enclosure 202.
  • the flow switch 222 may be coupled to any of the fluid paths for water/AOS flowthrough the system 100 (e.g., water input line 102, water output line 106, splitter 110, etc.).
  • the AOS supply unit 200 may be configured to dispense an aqueous ozone solution (e.g., a water and ozone solution) having an ORP of between 600 mV and 1000 mV to provide pathogenic control without introduction of harsh treatment chemicals, such as chlorine.
  • the output aqueous ozone solution can provide removal of organic and inorganic compounds, can provide removal of micro-pollutants (e.g., pesticides), can provide enhancement of the flocculation/coagulation decantation process, can provide enhanced disinfection while reducing disinfection by-products, can provide odor and taste elimination of the treated water, and so forth.
  • Corona discharge ozone can be used virtually anywhere. Since ozone is made on site, as needed and where needed, there is no need to ship, store, handle or dispose of it, nor any containers associated with shipping, storing, handling, and disposing a treatment chemical, as is the situation with most chemicals utilized in water treatment.
