Description

DISINFECTANT PROCESS AND FORMULATION

FIELD OF THE INVENTION

The present invention refers to an industrial process for the production of disinfectant formulations, through which at least two different products are obtained, the first consists of an alkaline formulation with a pH level between 10 and 12 and the second which consists in an acid formulation that achieves a pH level between 1 and 3.5 at the same level; Because it is a process where a configuration based on different types of filters is used, it can be considered a chemical patent.

BACKGROUND

In the state of the art, a large number of inventions can be found that provide acidic water for disinfectant purposes, such as the following:

WO2017186980A1 entitled electrolytic reactor for the production of disinfected and disinfectant water which discloses a portable device for the production of disinfected and disinfectant water formed by an electrolytic reactor comprising two consecutive electrochemical cells (1, 1 ') the first electrochemical cell comprising a first anolytic chamber (3) and a first catalytic chamber (5), concentric and separated by a first semipermeable membrane (7), whose anode (8) is in the center (10) of the reactor (100), with its cathode (9) in a concentric metal piece and comprising the second electrochemical cell (1'), at least a second anolytic chamber (3') and a second catalytic chamber (5'), concentric with each other and separated from each other by a second semipermeable membrane (7'). '), whose anode (8') is in an external metal part (1 1 ') of the electrolytic reactor (100), and whose cathode (9') coincides with the cathode (9) of the first electrolytic cell (1).

This invention calls for the electrolytic reactor (100) for the production of disinfected and disinfectant water, by treating at least one brine of a first metal salt (2), which enters through a main inlet mouth (13) and is subjected to the action of electric fields, and is separated, by the effect of the chemical electroactivation of water, into: a catholyte (C1, C2), containing cations, or disinfectant, protruding from at least one catalytic chamber (5, 5'); and an anolyte (A1, A2), containing anions, or disinfected water, exiting at least one anolytic chamber (3, 3'), characterized in that it comprises two consecutive electrochemical cells (1, 1'), each of which comprises in turn: the first electrochemical cell (1), a first anolytic chamber (3) and a first catalytic chamber (5), concentric and separated by a first semipermeable membrane (7), whose anode (8) is in the center ( 10) of the reactor (100), its cathode (9) being in a concentric metal piece; and the second electrochemical cell (1'), at least a second anolytic chamber (3') and a second catalytic chamber (5'), concentric with each other and separated from each other by a second semipermeable membrane (7'), whose anode ( 8') is in an external metal part (1 1') of the electrolytic reactor (100), and whose cathode (9') coincides with the cathode (9) of the first electrolytic cell (1).

However, and being a device for these purposes, it does not accurately describe the pH levels obtained from the separation, what it does characterize is the arrangement of the anode and cathode to cause electrolysis and also does not make evaluations on the product obtained. , but it is simply the device that is claimed in conjunction with the products obtained from it and at no time does it indicate filtration within the specific process that apparently is conventional.

Other inventions used for this type of products are patent FR2128678A1 entitled electrolytic cell: to sterilize drinking water or water for baths, which despite not having a cosmetic use, reveals an electrolytic cell for the sterilization of drinking water or water for baths, It has two concentric electrodes in an outer casing that defines an annular passage for the water to be sterilized. One or more guides connected to the annular passage are provided for the water flow, to which they impart a spiral rotation. And 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.

Now focusing on processes, water filtration is mainly seen for the purposes of industrial treatment of hard and waste water, among many others, but for cosmetic purposes and sometimes as a disinfectant, the documents found are incipient, therefore it is considered that the formulations obtained with this process are new until the date of presentation of this document.

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. To their use as medicines, health products or in tissue engineering or regenerative medicine, or with cosmetic, hygiene, nutritional and surface coating applications as well as procedures for their preparation.

DESCRIPTION

The characteristic details of this novel process and the disinfectant formulations obtained with said method are clearly shown in the following description and the accompanying figures, where the same reference signs are followed to indicate the parts and figures shown.

Brief description of the figures:

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;

Where the

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. which is hereinafter called sediments; Using ducts, 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 flow is sent to a fifth filter E, which is a filter that acts by reverse osmosis that consists of a semipermeable membrane to remove minerals and eliminate ions from the residual water obtained from the previous filter, now to pass it to a sixth filter F that It is an ozone filter consisting of a container through which ozone is passed, which eliminates the possible presence of bacteria and viruses in the water flow and finally the flow passes through a seventh filter G, which consists of completely deactivating viruses and bacteria with an ultraviolet light lamp;

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 chloride, potassium chloride gas and magnesium chloride in equal proportions to prepare a formulation for disinfectant purposes;

The formulation

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).

In order to provide sufficiency to this wording and to note its inventive activity, the following examples are presented in an illustrative, but not limiting, manner.

Example 1

In a sample with one unit of water and with the formulation obtained with residual chlorine, it has been observed that the number of E. Coli bacteria in a control group fluctuates between 2.1 and 3.7X10 ⁶ . In such a way that when applying the formulation with residual chlorine with a concentration of 0.05 ppm, the number of live Esterichia Coli bacteria was reduced to a level of between 2.1 and 2.3 x 10 ⁵ ; In the comparison with the number of bacteria of the original control group, the efficiency of the formulation has shown a disinfection level of 90%, but when the experimental group is increased then the efficiency of the formulation increased to levels between 99.1 and 100% with 0.4 ppm of Chlorine concentration and, finally, an efficiency of up to 100% was obtained with 0.8 ppm or greater.

Table 1 . Disinfection efficiency due to increase in residual chlorine

It is concluded that the super oxidation water generated with the method allows and has a residual chlorine concentration of 0.8 ppm.

Because the number of bacteria in the original control group was 2.1 to 3.7X10 ⁶ . With 400 mV of oxidation reduction potential, the number of live Escherichia Coli bacteria decreased to 4.0 to 5.7 X10 ⁴ . Compared with the number of bacteria in the original control group, observing then that a disinfection efficiency of 90% was achieved, now the increase to 92% with 800mV significantly decreases the bacteria, and finally up to 100% with 970 mV. We therefore conclude that the redox potential should be maintained at 1,000 mV or higher, in order to expect a more complete disinfection effect.

In the doctrine it has been observed that the disinfection of bacteria by OXIDATION water is achieved instantly, in such a way that the residual Chlorine (CI2) is used to obtain this disinfectant effect. 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.

On the other hand, it changes the metabolism of the bacteria by coupling with the proteins on the surface of the bacteria, then penetrating through the membrane of the bacteria cell and attacking the ATP, DNA, RNA, and NADH proteins contained in the bacteria.

It is considered that Chlorine gas changes the natural properties of these substances and kills bacteria quickly as has been reported in multiple studies.

Example 2

The existence of bacteria, 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. Just to refer to some particular cases, 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.

If the pH level decreases to values less than 4.0 or, on the contrary, remains at levels greater than 9.0, 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.
