- patent ES2645235T3 which discloses a bipolar cell for a reactor comprising the cell end electrodes and at least one bipolar electrode therebetween, the or each bipolar electrode comprising a diamond sheet, the cell including a porous support structure between each end electrode and the adjacent diamond blade and, where there is more than one diamond blade, there being a porous support structure between the or each pair of adjacent diamond blades, acting as support structures to contact and support the or each diamond blade.
- Patent W02011135150A1 reveals hydrogels made from anionic polymers of natural origin which comprise: (a) at least one polymer of natural origin endowed with a negative electrical charge; (b) at least one natural constituent molecule of the human organism capable of acting as a cationic cross-linker of the above polymer or polymers.
- Figure 1 is a flow diagram of the process used to obtain the disinfectant formulations.
- Figure 2 is a plan diagram of the process used to obtain the disinfectant formulations.
- Figure 3 is a graph that shows the spectrum of microbial existence by pH levels and through the axes AA' and BB' the point at which the concentrations of the formulation obtained with this invention are found is determined. Based on the previous figures, the process and the disinfectant formulations obtained are characterized because they comprise the following stages:
- Stage 1 The raw water is passed through at least seven filtrations of diverse physical or chemical nature as a preparation of water with mineral particles that are present in it and have a size less than one micron, to which
- Stage 2 It is separated by electrolysis to separate it as two types of products, the first that contains minerals and is alkaline and the second that contains minerals and is acidic; and
- Stage 3 Alkaline mineral water with a pH between 10 and 12 is used to make a first disinfectant product and acidic water with a pH between 1.5 and 3 is used to make a second disinfectant product;
- Stage 1 At this stage, raw water is placed in a conventional container (that is, water that has not received any treatment and has not yet been introduced into the distribution network found in sources and natural reserves of both surface waters (rivers, lakes, reservoirs). or canals) as groundwater (wells, springs or springs) therefore it contains organic matter, inorganic matter and microorganisms, as well as flavor, smell, color and turbidity,) from which it directs towards a first filter A, which can carry out the mechanically filtered either using a filter mesh or a ceramic filter with pores to eliminate waste and pathogenic organisms, in which particles with a size between 5 microns and 1 micron are retained, that is, those particles visible to the naked eye.
- a conventional container that is, water that has not received any treatment and has not yet been introduced into the distribution network found in sources and natural reserves of both surface waters (rivers, lakes, reservoirs). or canals) as groundwater (wells, springs or springs) therefore it contains organic matter, inorganic matter and microorganism
- the output of this filter is directed towards a second filter B, which consists of a container containing activated carbon to eliminate the chlorine present in the water coming from the first filter and possible residues of organic matter.
- the flow is then directed towards a third filter C which consists of a container with anion resin (strong base: eliminates carbonates and silicates, weak base: eliminates sulfates, nitrates and chlorides) consisting of spheres between 0.5 to 1 mm in diameter and consequently the flow delivered already It does not have sodium, chloride, calcium and magnesium ions present in it, but at the same time this action gives an equivalent amount equal to that eliminated but of proton or hydroxy charge to the water flow, which is then directed to a fourth filter D which is now a cationic resin which allows cations to be eliminated by exchanging sodium or protons when it contains a strong acid and when it is a weak acid, it eliminates the cations associated with bicarbonates; Subsequently, the
- Stage 2 With the previous mechanical process, the water obtained in stage 1 contains minerals present in extremely small particles, that is, those that are in ranges below one micron and therefore, a conventional electrolysis process is used to separate those that are present in the flow obtained in stage 1, from where when the electrolysis is carried out at ⁇ 100 millivolts then a first type of water is produced that is considered alkaline, that is, with a pH between 10 and 12 It is used to make a first disinfectant product and, upon hydrolysis with ⁇ 10,000 volts, a second type of water is produced that is acidic, that is, with a pH between 1.5 and 3, it is used to make a second disinfectant product; Stage 3
- the acidic water produced in stage two can be expected to have a pH between 4.5 and 5 for disinfectant use, however it has been obtained with pH levels between 1.5 and 3, so for its use the pH at levels between 2.2 to 3, an ORP of ⁇ 1,100 mw with residual chloride dissolved in a range of 10 to 60 ppm of a mixture formed of Doric
- the water obtained with the method described above is considered a disinfectant but shows high levels of oxidation (super oxidation) and has a residual dissolved chloride of between 10 to 60 ppm which in a first embodiment can be used directly as a topical disinfectant or in a second preferred embodiment it is found in combination with a gelling agent (carboxyl methyl cellulose).
- a gelling agent carboxyl methyl cellulose
- Chlorine attacks the amino acid radicals (NH2) exposed on the surface of bacteria, changing the natural properties of the protein exposed on the surface, destroying the surface layer, and killing the bacteria quickly.
- Chlorine gas changes the natural properties of these substances and kills bacteria quickly as has been reported in multiple studies.
- the pH of the environment is an important factor, because bacteria require a range of low pH values where they can survive, which is normally between 3.0 to 10.0.
- the range for "Tubercle Bacillus” is a pH that fluctuates in a range of 6.0 to 7.6, and for the bacteria “Lactic acid” and “fungus” the survival range is determined between a pH from 5.0 to 5.5.
- the Hydrogen Ions change the natural properties of the cell membranes and penetrate through them, and then have an indirect effect. in the process of its metabolism, until the death of the bacteria occurs.
- Oxidizing water with a pH level below 2.7 provides the conditions necessary to kill bacteria. However, this effect will not be instantaneous, but rather after a short time. Therefore, this pH condition is considered an indirect functional factor, but not the main factor of disinfection.
- Figure 3 shows a spectrum of conventional microbial existence and with the axes AA' and BB' allow identifying the point of action of the formulations developed in this invention.
- the pH level must be kept below 2.7, because the form of Chlorine contained in the oxidation water will depend on the pH values. Obviously, the disinfectant effect will depend on the pH concentration. If the pH remains within the strongly acidic range, the amount of Chlorine gas will be greater, and if it remains within the moderately acidic or weakly acidic range, the amount of hydrochloric acid (HOCI) will be greater. However, the formulation obtained is obtained with an optimized pH level against the technical effect of disinfection.
