Definitions

  • This invention relates generally to a water treatment system and more particularly, to a method and apparatus for treating water for livestock and poultry use by increasing the dissolved oxygen and reducing the oxygen reduction potential of the water.
  • Drinking water quality is an important factor for livestock and poultry health. Elevated concentrations of minerals, bacteria or toxic constituents in the water can have a detrimental effect on normal physiological processes in the body, thus causing inferior development, such as weight gain and growth. High concentrations of minerals can also restrict water flow to the birds by clogging the feeder lines. This can cause flooding of the drinkers and wet litter which, in turn, can lead to disease and leg problems.
  • Chlorination has been the most common method to treat water for bacterial contamination. Chlorination removes bacteria from the water supply by converting some of the chemical contaminants into less harmful forms. For example, chlorinization oxidizes nitrites to the less toxic nitrate form and reacts with hydrogen sulfide and ferrous iron to produce sulfates, ferris iron and other solid materials that can then be removed by filtration. Since chlorine reacts with organic compounds, however, its effectiveness as an antimicrobial agent is more quickly reduced if high levels of organic matter are present. Furthermore, although chlorination can kill some bacteria in the water supply, it does nothing to increase or improve the overall water quality of poor water. Another method used to control the quality of water is with polyphosphates. Polyphosphates are chemical compounds used to prevent the build-up of scale in the water system by causing the minerals to go into solution.
  • Yet another method for water treatment are magnetic devices that are designed to prevent scaling buildup.
  • Aeration equipment had been used to inject oxygen into water.
  • the primary purpose of the process is to oxidize organic water in wastewater and potable water applications.
  • Waste water aeration is primarily done under atmospheric conditions for the purpose of aerobic digestion.
  • air is bubble diffused within a tank to accomplish oxidation. It might then be repressurized for distribution.
  • a variety of ways are used to provide aeration under pressurized situations. Compressed air or concentrated oxygen could be injected into a water stream or could be drawn into a water stream with the aid of a venturi.
  • water could be passed through an air pocket within a tank to accomplish aeration.
  • a water treatment system for treating water for use with livestock and poultry.
  • the system includes a water treatment filter, a flow meter that coordinates with a flow switch and an electrocatalytic cell coupled to a holding chamber that is attached to an outlet of the cell.
  • the water treatment filter removes materials from the water that alter the electrical properties of the water prior to the water entering the electrocatalytic cell.
  • the electrocatalytic cell includes a plurality of conductive plates with spaces therebetween through which water may pass. An electric current flows across the conductive plates of the cell through the water, breaking some of the water molecules into their component parts of hydrogen gas and oxygen gas. At the outlet of the cell, both hydrogen gas and oxygen gas are present in the fluid.
  • the holding chamber is vertically oriented and longitudinally extending from the outlet of the electrocatalytic cell.
  • the vertical length of the chamber is selected to provide sufficient time to allow a majority of the gaseous oxygen to transition to dissolved oxygen.
  • a collection valve may be included at the top of the holding chamber to allow collection and release of accumulated gases.
  • An optional sediment filter may be added after the outlet from the holding chamber prior to the water reaching the livestock drinking system. Additional features include bypass piping and valves allowing the water to flow around the system so that water flow to the animals is uninterrupted if maintenance is required on the system.
  • the system may further include the control unit allowing modification of the current density in the conductive plates of the electrocatalytic cell based on the value of the flow rate measured by the flow meter.
  • the control unit may further provide a memory unit allowing recordation of information for a given amount of time. Access to the memory unit may be provided via a modem link, alternatively, a direct link at the control unit may also provide access to the memory unit.

  • FIG. 1 and 2 illustrate a water treatment system 10 wherein water is input in the system at "A" and water is output out the system at "B" for use in a livestock drinking system.
  • FIG. 1 illustrates one layout of the water treatment system 10.
  • water enters the system 10 at point A, coming into the system 10 under pressure, typically from a pressure tank, a pump, or line pressure from a municipality.
  • the water progresses from entry point A through a treatment filter 12, through a flow meter 17, and into a treatment unit 11.
  • the treatment unit 11 includes an electrocatalytic cell 18.
  • the water flows across conductive plates (shown in Figures 3,4) in the electrocatalytic cell 18 and into a holding chamber 20.
  • An upper portion 22 of the holding chamber 20 includes a gas release assembly 22 that allows gases to egress through a gas vent 25 in a collection valve 24 positioned at the top of the gas release assembly 22.
  • the gas release assembly 22 includes an outlet 26 to allow the water to flow out the outlet 26 of the upper portion 22 of the holding chamber 20 and through a check valve 28.
  • the check valve 28 prevents backflow of water into the treatment unit 11.
  • the water proceeds out the exit piping 27 and through an optional sediment filter 30 exiting the water treatment system 10 at point B ready to be used in a livestock drinking system of any acceptable type.
  • Typical livestock drinking systems for poultry include drinker lines with stainless steel nipples for the birds.
  • pressure reducer valves may additionally be included in the system.
  • the water treatment unit 11 should be positioned on the high pressure side of any pressure reducers.
  • a tee 40 Prior to entering the treatment unit 11, a tee 40 may be positioned in the pipe.
  • Valves 42 and 44 may be opened and closed as desired to direct the flow of the water. To direct the flow of the water through the treatment unit 11, valve 42 is opened and valve 44 is closed.
  • valve 42 can be closed and valve 44 opened to allow the water to flow around the treatment unit 11 and into the livestock drinking system as untreated water via piping 46.
  • the water re-enters the treated water line at a pipe tee 48 and then flows through exit piping 26 to the livestock drinking system.
  • a valve is placed in line 46 though it is not present in a first design.
  • the valve in line 46 prevents water from flowing back into the bypass piping 46. It can be a check valve or a controlled valve that is opened and closed as desired. Similar to the opening and closing of valves at the inlet of the system, when the bypass piping 46 is being used, check valve 28 is closed and its valve is open. Alternatively, when the treatment unit 11 is being used to process the water, check valve 28 is open to permit flow out of the system, but will prevent flow in reverse back into the treatment unit 11 and the valve in line 46 is closed.
  • This bypass piping configuration allows the user to choose between treating the water by closing valve 44 and opening valve 42 and thereby running the water through the treatment unit 11 or alternatively bypassing the treatment unit 11 by opening valve 44 and closing valve 42 to allow the water to bypass the treatment unit 11 entirely. This will be advantageous to allow routine maintenance or replacement of parts on the treatment unit 11. Standard elbows 50, tee's 40,48 and union pipe couplings 52 appropriate for the gage, size and type of the piping used will provide connections for the water line.
  • the treatment unit 11 is mounted in a vertical position with mounting brackets 54,56 and corresponding pipe clamps 55,57 or similar securing hardware. Rigid pipe connections entering and exiting the treatment unit 11 encourage a secure and fixed mounting of the treatment unit 11.
  • the treatment filter 12 is placed, in one embodiment, after valve 42 and prior to flow meter 17.
  • the filter 17 removes materials that make the water hard.
  • a treatment filter is a conventional water softener system such as a cell resin bed softener filled with salt. Duplex systems may be used wherein one tank is regenerating while the other tank is treating the incoming water. It will remove calcium, magnesium and other hardness minerals from the water to create soft water. The calcium and magnesium atoms are replaced with sodium to make the water soft, as is well known in the water softener art.
  • the filter 12 may also be placed at inlet point A, prior to the bypass piping.
  • Yet another alternative treatment filter 12 that may be used is a reverse osmosis (R/O) system.
  • R/O reverse osmosis
  • the R/O system includes a semipermeable membrane which forms a very tight filter through which the incoming water must flow. Increased pressure pushes the water through the semipermeable member while wash water across the membrane keeps the membrane clear of contaminants. Bacteria is removed in this system down to the micron "level. Further, under the R/O system, the water conductivity is taken down to 10 microsemens. An R/O system removes nearly all minerals and all other impurities from the water and thus results in very clean, pure water.
  • Magnetically induced resonance (MIR) devices include a series of powerful magnets. These affect the mineral clusters and cause them to remain in solution by changing the electrical properties of the molecules of the mineral and/or the water.
  • the water softener could remove some portion of the minerals and the magnets could alter the properties of the remaining materials such that they remain in solution and pass through the system 11.
  • the water filter 12 is not shown to scale in correct size, but is shown only schematically. As will be appreciated, a conventional water softener using a resin bed with salt may be much larger in size than the treatment unit 11 or electrical control box 32, particularly if a duplex tank system is used.
  • the reverse osmosis system is also of a different size and includes further piping as is known for such filters.
  • filter 12 The purpose of filter 12 is to standardize the mineral content and electrical properties of the water prior to treatment. As is known, some water is very hard and thus is high in calcium, magnesium, iron or other minerals. If these pass into electrocatalytic cell 18, they may cause build-up and scaling on the plates. They may also shorten the life of the plates and affect their electrical properties over time. It is therefore desired to remove from the water those compounds and elements that will cause clogging of the plates or decrease the effectiveness of the plates over time.
  • water flows through a flow meter 17 whose electronic signal output is connected to a control unit 32.
  • the data from the flow meter 17 is used by control unit 32 to control the current provided to the cell 18 based on the flow volume registered by the flow meter 17.
  • Current density is regulated through the electrocatalytic cell 18 and is increased or decreased proportional to the flow as measured by the flow meter, as explained in more detail later herein.
  • the flow meter 17 can be any acceptable type. It can be based on an ultrasonic sensor, a doppler shift technique, a Hall effect sensor, a mass flow meter, or any acceptable type of flow meter used for water or other liquids.
  • the flow meter 17 outputs an electronic signal indicating the flow rate of water through it. The output can be analog or digital. The signal is received by the controller 32 and used for current density control of the plates, as explained herein.
  • the water flows through the flow meter 17 and into the inlet 14 of the treatment unit 11.
  • a magnet or MIR device can be placed around the inlet 14 if desired, just prior to the cell 18.
  • Below the inlet 14 in the treatment unit 11 line i_5 a discharge valve 15.
  • the discharge valve 15 may be opened to drain the treatment unit 11 in cases of routine maintenance or alternatively to drain sediment out that has precipitated out and settled to the base of the treatment unit 11.
  • the holding chamber 20 is a separate unit coupled to the electrocatalytic cell 18 via a standard connection.
  • an optimum length 1 of the holding chamber is related to the flow rate desired, as well as the diameter of the holding chamber 20 and other factors.
  • the diameter of the holding chamber 20 may be made larger than the diameter of the cell, providing a slower flow rate and longer resident time for the same volume of flow rate.
  • One preferable ratio of volume of water between the holding chamber and the cell chamber is 7:1.
  • Water proceeds from the holding chamber 20 into an upper portion 22 of the holding chamber 20 that included a gas release assembly 23.
  • the water in the treatment unit 11 proceeds out the outlet 26 while any gases are collected in the gas release assembly 23. Opening a collection valve 24 allows gases to vent out a gas vent 25.
  • a check valve 28 prevents water from back-flushing the system.
  • Water proceeds out the exit water piping 27 into the sediment filter 30.
  • the sediment filter 30 prevents sediment from entering the livestock drinking system.
  • the sediment filter 30 can be a self-cleaning, back-flush type, filtration device. Filters of this type operate via a backwash cycle that cleans the filter without interrupting the main system water flow. These filters operate on line pressure alone.
  • the sediment filter 30 may be a simple course screen that requires periodic cleaning or replacement.
  • Typical livestock drinking systems for poultry include drinker lines with stainless steel nipples for the birds. These stainless steel nipples are easily clogged by sediment, and if clogged, require intensive manual labor to individually replace or unclog. Clogged feeder lines left unattended can cause flooding of the drinker lines and wet litter in the feeding area that can cause disease to the birds or leg problems.
  • the electronic controller 32 includes a microprocessor, a memory, a power supply circuit and all other electronics needed to control and monitor the electrolytic cell. Power is provided into the controller 32 as AC power in.
  • the controller 32 includes an AC to DC converter to generate a DC output of the proper voltage and current values.

  • a communications connector 74 for connection to the outside world is provided via line 73.
  • Other access ports 76 can be connected via line 75.
  • An additional port 69 is provided for future peripheral expansion as desired. Further, port 75 may also be used for further peripheral expansion as needed.

Indicator light 1204 indicating that cell is active is illuminated. A ramp is established starting at zero and having a desired slope. The power will increase gradually and will be stable at the desired amperage level after a certain period of time.

This preserves the life of the plates and avoids sudden hotspots as may occur if a step change in voltage is placed on the plates when initially switched on.
  • the soft power change circuit operates when power is on and is changed from one value to another value.
  • the change will be in the form of a ramp that slowly moves from one amp to two amps.
  • This ramp slope is preferred to be more gentle than the soft start ramp and will change the power more slowly.
  • the ramp will be as such that it may take 20 to 30 seconds to change from one amp to two amps.
  • the control 32 thus has two soft current change circuits.
  • the first is a steeper slope that is used to place current on the plates from a no-power mode to power on mode and the second is a different, less steep slope, that changes the power from an existing on current flow to a different current value.

In one embodiment, this acceptable maximum value is 55 amps. As will be appreciated, this value can be sent at any other level as desired for each given application.

Alternatively, if the cell is active for a portion of the six-hour period then, the average current and voltage over that six-hour period is stored.

Abstract

L'invention concerne un système de traitement d'eau utilisé avec le bétail et la volaille. Ledit système comprend un filtre de traitement d'eau, un débitmètre qui fonctionne avec un contacteur débitmétrique et une pile électrocatalytique couplée à une chambre de retenue qui est fixée sur une sortie de ladite pile. Un courant électrique s'écoule à travers des plaques conductrices dans la pile dans l'eau, ce qui entraîne la rupture de certaines molécules d'eau en parties de composés de gaz d'hydrogène et de gaz d'oxygène. On sélectionne une longueur verticale de la chambre pour générer suffisamment de temps de manière à permettre à une grande partie de l'oxygène gazeux de se transformer en oxygène dissous. Une unité de commande génère une modification de la densité de courant dans les plaques conductrices de la pile électrocatalytique en fonction de la valeur du débit mesuré par le débitmètre. L'unité de commande comprend, en outre, une unité de mémoire permettant l'enregistrement d'information pour une quantité de temps donnée. L'accès à l'unité de mémoire et de commande peut être engendré par liaison modem. D'une autre façon, une liaison directe au niveau de l'unité de commande peut également fournir l'accès à l'unité de mémoire.
