Definitions
- This invention relates to the processes of water disinfection which is particularly based on the oxidation of contaminants (viruses, bacteria, algae, organic substances, etc.) present in contaminated water by means of hydroxyl ions produced by water hydrolysis.
- Water disinfection processes according to the present invention are based on the production of hydroxyl ions, a highly effective oxidizing species, obtained by hydrolysis of water molecules that "oxidize" pollutants and / or the organic substances present in the bodies of the contaminated water, regardless of the specific conductivity of the water in the treated water.
- the "oxidation" chemical contaminants in water is related to the conventional chemical process currently in which l ° s chemicals (chlorine, bromine, etc.) or electronic processes such as systems used salt or ozone electrolysis generators.
- hydrolysis processes with low conductivity water are not very effective since the generated amperage will not be sufficient to obtain the necessary levels of hydroxide ions to properly disinfect the contaminants present in the water (viruses, bacteria, seaweed, etc.)
- hydrolysis in high conductivity water suffers from problems in the power supply for the generation of hydroxyl ions.
- the problem is in the electronic control unit that supplies the continuous voltage at the electrodes, because the high conductivity of the Water can damage the electronic system of the control unit due to excessive drainage of current.
- the current invention provides a new process whereby the voltage in the electrodes is automatically regulated by means of an electronic control unit that measures the conductivity of the
- the invention encompasses a programmed electronic control unit, which determines the correct amount of hydroxyl ions generated. In this way, the efficiency related to the amount of hydroxide ions generated is guaranteed since the conductivity of the water will not adversely affect the generation of hydroxide ions for the oxidizing pollutants present in water, thereby maximizing oxidation, without Import conductivity.
- this invention benefits water disinfection processes with this technical advantage and therefore eliminates the current 0 limitations of hydrolysis of water molecules with an electronic and adjustable system.
- Hydrolysis of water molecules is a chemical process in which a water molecule is dissociated into various fragments by electrical energy.
- the main hydrolysis reaction is given as:
- the dissociation of the water molecule implies a standard oxidation-reduction potential of (E s ) 1.8 V.
- the dissociation is very weak, whose reason is necessary to reach a certain level of solids in suspension and of conductive molecules (corresponding to the parameters of TDS (total solids in solution and conductivity, respectively, under regular water tests) so that this process acts effectively as a disinfectant agent in water.
- TDS total solids in solution and conductivity, respectively, under regular water tests
- the invention produces the most powerful oxidizing oxidant species for the water it disinfects, avoiding the use of chemicals.
- the oxidation-reduction potential is 2.05 V, and its effect is exceeded only by fluorine that cannot, however, be used as a disinfectant. chemical due to its high toxicity.
- Figure 1 demonstrates the main reaction of the hydrolysis of water molecules, wherein the water molecule dissociates into various groups due to the injection of electrical energy with a pair of electrodes (6) on it.
- Figure 2 demonstrates that the water molecule is a highly stable chemical substance, which neither readily dissociates nor ionizes.
- the H20 molecule is composed of two hydrogen atoms and an oxygen atom.
- Figure 3 demonstrates that at a standard pressure and a temperature, elemental hydrogen is a gas with the molecular formula H2. Both hydrogen atoms share two electrons.
- Figure 4 demonstrates that at a standard pressure and a temperature, elemental oxygen is a gas with the molecular formula of 02, with 8 protons, 8 neutrons and 8 electrons. Each oxygen atom shares 4 electrons with another atom.
- FIG. 5 demonstrates that in H20, composed of two hydrogen atoms and one oxygen atom, each hydrogen core is limited to the central oxygen atom by a pair of electrons that are shared between them.
- TABLE 6 demonstrates that when a hydrogenated ion is released to move, the second hydrogen atom is bound to the oxygen atom with which it shares 10 electrons. This results in another negative ion since the number of electrons exceeds the number of protons. Therefore a negatively charged hydroxyl is produced.
- Figure 7 demonstrates the control unit of the invention.
- Figure 8 is a front view of the electrode chamber.
- Figure 9 is a side view and demonstrates the electrical connections of the electrode chamber.
- Figure 10 is a system diagram demonstrating a water source with a filter system which carries and provides water to the disinfection system of the present invention.
- FIG 11 is a more detailed block diagram of the disinfection system of TABLE 10.
- FIG. 12 is a more detailed block diagram of the controller in TABLE 11.
- Oxidizer species generated by the system of the invention are Oxidizer species generated by the system of the invention.
- Water structure The water molecule is a highly stable chemical. It neither dissociates nor easily ionizes.
- the H20 molecule is composed of two hydrogen atoms and an oxygen atom (see fig. 2).
- Hydrogen At a standard pressure and temperature, elemental hydrogen is a gas with the molecular formula H2. Both hydrogen atoms share two electrons (see fig. 3).
- Oxygen At a standard pressure and temperature, elemental oxygen is a gas with 02 of the molecular formula, with 8 protons, 8 neutrons and 8 electrons. Each oxygen atom shares 4 electrons with another atom (see ⁇ g. 4).
- Water molecule In H20, composed of two hydrogen atoms and one oxygen atom, each hydrogen core is limited to the central oxygen atom by a pair of electrons that are shared between them (see fig. 5, which demonstrates an equilibrium position of positive and negative charges in a water molecule).
- Ionization When an electric current is applied to water, electrolysis and ionization occur. One of the hydrogenated ions escapes the potential electrical barrier that it limits to the water molecule, thus producing a hydrogen atom with a single proton and no electrons. When the negative electron exceeds the potential electrical barrier, hydrogen becomes an ion with a positive electrical charge.
- Ions The atom that has acquired an electric charge is called an ion. Ionized atoms have a negative or positive electrical charge. Ionized atoms can have one or more negative or positive electrical charge. This happens when the atom releases or takes one or more electrons, thus changing the electrical balance between protons and neutrons.
- An anion is an ion with more electrons than protons, giving it a negative charge.
- a cation is an ion with more protons than electrons, giving it a positive charge.
- Conductivity By knowing the amount of ions dissolved in water, the "conductivity" parameter is used to characterize the type of water.
- a sodium ion is positively charged and a chlorine ion is negatively charged.
- the result of their combination is table salt; with a neutral electric charge (i.e. it has no electric charge).
- the salt is dissolved in distilled water, the sodium becomes a positively charged ion and the chlorine is negatively charged and the water becomes conductive.
- the symbol of the chlorine atom is Cl and the symbol of a chlorine ion is C1-.
- FIG. 7 shows a control unit (7) with internally incorporated electronic boards that converts the standard electrical energy (220 V or 110 50 or 60 hertz V.) into electric power of the bass- Continuous voltage-and-amperage which will then be applied to the electrodes located in the electrode compartment or chamber (6) manually or automatically. It has a programming and operation keypad (1) to adjust time, program, other actions according to the model and mode of operation.
- control unit is such that the voltage sent to the electrodes (6) is automatically and continuously adjusted, therefore said adjustment is based permanently on the conductivity of the water to obtain the desired amperage for the generation of the ion of hydroxide needed to oxidize pollutants, regardless of water conductivity and without limiting efficacy, as in current technologies.
- COMPARTMENT OR ROD OF THE ELECTRODES One or more compartments are made according to the indications of TABLES 8 and 9 and depending on the application and flow, to achieve the desired purpose of handling the type of contaminated water that will flow the water into they through the entrance and exit the chamber or electrode compartment. They have one or several pairs of titanium electrodes installed in parallel with a distance of at least 0.5 millimeters (depending on water conductivity and depending on the application this distance may vary). Each electrode has an electrical connection with which the control unit cable is connected and with which the appropriate direct current is sent for the effective hydrolysis of water molecules to occur regardless of conductivity.
- the electrical energy is sent to the titanium electrodes (covered with noble metals) that works as a cathode-anode pair for the hydrolysis of water molecules using contaminated water as a raw material for their disinfection process (see TABLE 9 electrical connection) (7).
- the water molecule dissociates and transforms into a large amount of hydroxyl ions (OH -), monoatomic oxygen (O ⁇ ), etc., thus creating a combination of the existing oxidizing species (OH-) with more oxidizing effect for water disinfection, avoiding the use of chemical products in the particular hydroxyl ion box generated by the hydrolysis of water molecules, the oxidation-reduction potential is 2.05, exceeded only by the potential for fluorine.
- the method of the present invention is easy to execute due to its simplicity (see TABLES 7, 8 and 9) since it requires only one electronic control unit and one or more compartments for titanium electrodes, depending on the type of water and the application, where ion production of hydroxyls for the oxidation of the contaminants present in the water that crosses the electrode compartment.
- the electrode compartment (6) (8) can be transparent to make the electrodes visible.
- the drawing shows the front view of the compartment (8).
- the side view of the electrode compartment shows its components: compartment or chamber of electrodes (8), a pair of electrodes (6), cable connections (7) of the electronic control unit (2), water inlet plug (9) and water outlet plug (10).
- a Model 100 water disinfection circuit comprises a water reservoir 102, which can be a private pool, a drinking water tank in a home and the like, containing the filtration and disinfection that require the water 104.
- a water conduit 106 supplies the water to a filter 108 that supplies the filtered water through a conduit 110 to the water disinfection system 112 of the present invention.
- the filter 108 may contain several pumps and the other water regulating apparatus to allow removal and pumping of the water through the closed system shown in TABLE 10.
- the disinfection system uses the principles of hydrolysis of the present invention to disinfect and decontaminate water and then to return it via conduit 114 to water tank 102.
- the decontamination system 112 is shown to encompass one or more compartments or electrode chamber 112a, 112b, 112c, etc. of which all of them are supplied by an electronic current to create hydroxyl ions to disinfect the water flowing through the compartments or electrode chamber by the operation of regulator 120.
- the controller 120 shown in Figure 12 is coupled to an alternating current (ACV) power supply 122 which can supply grid voltage to a voltage converter and the regulator which is used to produce a voltage very low in the range of approximately 1 to 24 Volts and be regulated very carefully in terms of its amplitude to produce just the right amount of electrical current flowing through the water of the electrode chambers or compartments 112.
- ACV alternating current
- the output as a small voltage of the magnitude at which it can start eg, 1 V
- the current current meter 128 detects the conductivity of the water through the current to detect that maximum current level is not exceeded by providing its current detection output to the voltage regulator 126.
- the voltage regulator 126 is also sensitive to a user interface 130. The voltage slowly intensifies to obtain just the correct amperage through the water in the electrode chamber or compartment 112. This is a closed system and an ongoing process as previously described.
- Implicitly within the system of Figure 12 is the need to measure the specific water conductivity 104 which can be treated in this given application.
- a flow detector can provide activation or deactivation of the regulator at the time that water circulates.
- the measurement of water conductivity is a process that is performed indirectly by regulator 120.
- the electronic control unit outputs an initial voltage of, eg, 1 Volt of direct current (DCV) to the electrodes that are in contact with water.
- DCV direct current
- An initial current is detected by flowing between the electrodes and through the water and this current intensity is communicated again to voltage regulator 126. If the current in the electrode does not exceed a maximum current allowed in the system by the electronic control unit, the voltage gradually increases or decreases until the desired and predetermined current is reached " of the set point "that has been preset in the voltage regulator to produce an efficient amount of hydroxyl ions through our hydrolysis process. At that point, the voltage output remains at its level while the process works continuously to disinfect the water. This is a closed or open circuit system that works in continuous process and does not stop as long as water circulates through the electrode chamber.
- the electronic control box will increase the output voltage to the electrodes to reach the desired current between the electrodes. Conversely, if the conductivity of the water is too high, that is, the water has a low resistance to the electric current, the electronic control box will adjust the voltage down to maintain the desired optimum current at the "set point".
- the setpoint current is a value that is intended to be maintained once the system is in a work mode and is also a parameter that is adjusted or programmed by an installer or at the factory depending on the particular model or use . For example, in certain uses, a greater current may be desired to produce a greater amount of hydroxyl ions and increase the yield in the water disinfection process.
- the closed system of regulator 12 can work at a periodic rate that involves adjusting the voltage at a rate of once a second or at higher or slower rates depending on a desired use. It can include a hysteresis lock to prevent adjustment of the output voltage if the current is not changed by more than a predetermined amount between the measurements.
- the system of the present invention can work with or without an external filter.
- an internal filter that can be a static filter or a different type of filter can be provided at the entrance to the decontamination system.
- the electrodes are titanium electrodes coated with noble metals to protect the base of the electrodes from the oxidation itself produced by hydroxyl ions.
