Definitions
- the subject of the present invention is a general method for disinfecting water, whether it is water from sanitary installations of the type sinks, siphons, pipes, water used for food as drinking water, as well as dilution and rinsing water for the decontamination of surfaces and soils, of the type used as an active agent for sodium hypochlorite.
- the invention also relates to compositions for carrying out this process.
- sodium hypochlorite is known to be an effective agent, used for sanitary installations and surfac in order to destroy any contaminating microorganism. It is recognized sodium hypochlorite, at the concentrations usually used in trade, meets AFNOR standards in thirty seconds. Likewise, other chemical agents may be used as decontaminants such as:
- the invention aims to remedy these drawbacks.
- a general process for disinfecting water is proposed, whether it is water sanitary installations such as sinks, siphons, pipes,
- REPLACEMENT SHEET used in food as drinking water, as well as dilution and rinsing water for the decontamination of surfaces and soils, of the type using sodium hypochlorite as active agent, characterized in that it consists of forming hypochlorite in situ, the excess then being decomposed into water and free oxygen.
- the invention also relates to redox systems for implementing the water disinfection process. These redox systems ensure, by the same operation, the progressive decomposition of sodium hypochlorite according to the following reaction:
- the aqueous solution contained in the siphon or in any other container or pipe is thus treated and decontaminated by exposure to the action of sodium hypochlorite (active chlorine in CIO form). It is not necessary to monitor this operation, nor to add the reducer a posteriori, because the latter present at the start acts to decompose the active chlorine (CIO-) by transformation into harmless reaction products of the chloride, water, nascent oxygen type , etan given that to have a decomposition reaction of sodium hypochloride it is important to control the reaction by adding an excess of reducing agent.
- sodium hypochlorite active chlorine in CIO form
- the first object of the present invention is to propose a composition and an operating process involving a unique manipulation, therefore of greater safety and more practical while avoiding any error.
- Another object of the invention is to propose a process which makes it possible to discharge into the waste water a neutralized solution free from any corrosive redox power limiting the aggravation of imbalances in certain natural environments.
- French patent 83 06608 describes a method for cleaning and sterilizing contact lenses in which an active agent is used, sodium hypochlorite formed in situ and the excess of which is then decomposed into sodium and free oxygen.
- this system is limited
- the oxidizing compound will be a chlorinated derivative such as dichloroisocyanuri acid in the form of sodium or potassium salts, the reducing agent possibly being organic or inorganic.
- a peroxocomp such as percarbonate, perborate, the alkali metal persulfates will be used, this in a nonlimiting manner.
- the amount of oxidant to be used varies from about 100 ppm of active chlorine to 5000 ppm.
- sodium dichloroisocyanurate will be used at the concentration releasing 1000 ppm active chlorine.
- the quantity of reducing agent which must be used to reduce sodium hypochlorite according to favorable kinetics varies from about 50 ppm of hydrogen peroxide to 1000 ppm.
- sodium percarbonate will be used as a hydrogen peroxide donor releasing ppm of hydrogen peroxide. 5
- the user pours the total of a sachet or tablet into the siphon or any other water point, at the end of the day by rinsing the walls of the siphon lightly.
- the product remains in contact with the solution for a sufficient period ranging from 5 minutes to 4 hours or overnight.
- the siphon or other water point is disinfected ready to be used without further treatment.
- the process described above makes it possible to disinfect the sip or other elements daily or according to a rhythm to be defined according to the initial contamination rate or according to the speed of recontamination.
- the process also makes it possible to decontaminate drinking water
- REPLACEMENT SHEET abnormally loaded with microorganisms. according to the same principle consisting in pouring into the container containing the water to be made potable all of a sachet or tablet corresponding to the volume of water to be decontaminated.
- the substances which are used in the present invention namely the oxidants and the reducing agents, are chosen so that they do not affect either the quality of the environment, that is to say waste water, or the health of the consumer.
- the solution after dissolution and neutralization will comply with the standards for microbiological acceptance of drinking water and will contain a residual level of active chlorine close to 0 ppm.
- effervescent excipients or stabilizing agents such as sodium or potassium bicarbonate, mannitol, adipic acid, citric acid, sequestering agent.
- suitable non-toxic excipients allowing, on the one hand, the delayed release of the reducing agent and, on the other hand, making it possible to avoid the chemical incompatibility between the oxidant and the reducing agent during the preservation of the product, must also be used in combination. with the compositions of the invention.
- the presentation can be carried out with a double-core tablet or multi-layer tablet with coating of the reducing agent, or in double sachet in the form of granules.
- the release of the product is controlled over time: - the oxidizing compound which releases the sodium hypochlorite - then the reducing neutralization product all in the same medium.
- the action can be reinforced if an effervescent system is used in addition to the compounds described above, a product which releases, after dissolving carbon dioxide, the mechanical action of which homogenizes the reaction medium.
- This system can be chosen, for example, without limitation, between sodium bicarbonate and adipic acid.
- compositions are to be dissolved respectively in 250 and 2 liters of solution.
- the presentation in bipoche sachet and defined formulation avoids the possibility of reaction between certai
- acidic compounds such as adipic acid and sodium bicarbonate in an environment with high humidity.
- mannitol is advantageously added as a diluting agent.
- Each layer is lubricated with sodium benzoate or PE 6000.
- the tablets are to be dissolved in 500 ml or 1 liter of water and left to act at least 15 minutes before consumption.
