Definitions
- the present invention relates to a method for activating liquids composed of polar molecules, such as, for example, water, and its implementation device. It also relates to the stimulation of the chemical reactions of products dissolved in activated liquids as well as the use of these solutions, in particular, for the disinfection of liquids, for example drinks, swimming pool waters, thermal waters, rejection. This use extends in particular to the fields of the food industry, medicine, sanitary industry and public health.
- Bail C.O. Oison F.S.W. "Sterilization in Food Technology, New York, Mac Graw Hill Book Company 1957, 654 p.;
- many drinks are disinfected using chemical preservatives based on benzoic, sorbic acids, organic acids, alkali metal salts and the like.
- the amount of preservative added to fruit juices can reach and sometimes exceed 20 mg / 1.
- preservatives can create parasitic tastes in juices. In addition, absorbed by the body, they create harmful substances that accumulate there. Efforts are made to reduce the quantity of preservatives by optimizing the composition (see [4]).
- swimming pool water which is disinfected by adding products such as chlorine, sodium hypochlorite and others. Part of this water is absorbed by the body. In addition to irritation of the mucous membranes, the appearance of chlorine in the body creates respiratory and other disorders.
- chlorinated drinking water where the added chemical has harmful, albeit weak, effects.
- Chlorine or sodium hypochlorite added to the waters of thermal pools for their disinfection, practically completely destroy the medical qualities of these waters, due in particular to the presence of sulfides which remedy many diseases.
- Discharge water is treated chemically before being discharged into watercourses, which helps destroy the flora and fauna of rivers and lakes.
- the concentration of many chemicals used in pharmaceuticals is limited by their harmful secondary action on the body. There are many other examples, confirming the negative action of chemicals used in solutions, for the body, the environment and the general state of the substances on which these products are intended to act.
- a process and a device for activating salt water by electrolysis is proposed in Swiss patent application No. 03367/95 (Process for obtaining sterilizing and / or stimulating liquid agents and device for implementing the process [ 5]).
- the process proposed in this patent application consists in passing an electric current through the water, which the electrolysis separates into two components, located at the electrodes, one, acid, the agent AW (anode water) and the another basic, agent CW (cathode water). It is noted in this patent application that the transformations are accompanied by a declusterization of the water accompanied by an accumulation of energy by the liquid. Certain specific properties of the agents AW and CW have been highlighted, in particular the sterilization of AW.
- the agent AW which contains, as a result of electrolysis, a certain concentration X of NaOCl has bactericidal properties, appreciably more pronounced than the same quantity of untreated water, containing the same quantity X of NaOCl.
- the treatment proposed in [5] is an activation treatment of the water + NaOCl solution.
- the disadvantage of this process is that the agent AW is the result of an electrolysis and its chemical composition depends on the initial chemical composition and on the set of parameters determining the electrolysis process.
- the aim of the present invention is to propose a physical process for activating the solvent (water, for example), independent of any phenomenon of electrolysis at the electrodes, which makes it possible to accelerate the action of the dissolved chemicals, and therefore to increase the efficiency, or, for the same efficiency, to decrease the concentration in the solution.
- the invention relates to a process for obtaining stimulating liquid agents as defined in claim 1.
- the invention also relates to a device for carrying out the process, as defined in claim 2, as well as the liquid agent as a product of the process.
- the process consists in using a liquid whose molecules are polar (water, ammonia, etc.) and which, in the normal state, is composed of clusters, containing ⁇ 10 2 molecules and subjecting it to the action of a electric, direct, alternating or pulsed field and current.
- a liquid whose molecules are polar (water, ammonia, etc.) and which, in the normal state, is composed of clusters, containing ⁇ 10 2 molecules and subjecting it to the action of a electric, direct, alternating or pulsed field and current.
- Electrochemical reactions at the electrodes giving rise to chemicals are avoided by separating the activation zone (zone B) from the anodic (A) and cathodic (C) zones.
- the electrochemicals which form in zones A and C do not have access to zone B.
- the electric current crosses the three zones.
- the treated liquid separates into three products, all three metastable, one of acidic property (AW), the second neutral, and the third basic (CW).
- the second product will be designated by the letters BW.
- the agent BW has the advantage of being able to be used at ambient temperature, on an industrial scale, as a neutral medium accelerating the chemical reactions of the products which are dissolved therein with the substances which it is desired to treat with these solutions.

- a volume of liquid formed of polar molecules for example water to which a product is optionally added
- polar molecules for example water to which a product is optionally added
- the volume of liquid is divided into at least three zones, separated from each other by membranes, permeable to the movement of cations and anions under the action of the electric field, but not allowing (or obstructing) molecular exchange by convection. This makes it possible to physically separate the central zone B from the anodic A and cathodic B zones where anodic and cathodic electrochemical phenomena take place respectively.
- the activation state therefore has a life time which can be characterized by a degradation period T depending on the recovery kinetics of the clusters and their rate of diffusion in the medium.
- the sterilization reaction has been chosen, i.e. destruction of microorganisms (for example: Bacillus subtilis) with a solution of sterilizing product (for example NaOCl).
- a solution of sterilizing product for example NaOCl
- Two media were compared with each other: on the one hand a solution of NaOCl of concentration x in distilled water, not activated, on the other hand a solution of the same concentration in activated distilled water (BW).
- the initial concentration of Bacillus subtilis was - 10 7 for a sample volume of 100 ml. The exposure times varied from 2 min. 60 min. It was verified by direct measurements of concentration x that the process activation of the water does not cause a change in NaOCl concentration.
- FIGS. 9 to 14 The results of the experiments are illustrated in FIGS. 9 to 14.
- FIG. 9, corresponding to a NaOCl solution (concentration x 9 mg / 1), shows that the activation of the water strongly stimulates the process of chemical destruction of the micro-organisms: for an exposure time of 20 min., it can be seen that the antimicrobial efficacy of the BW solution is more than 3 orders of magnitude greater than that of the solution in unactivated water.
- Figure 10 illustrates the influence of the degree of activation of water on its stimulation capacity.

- Figure 14 illustrates an alternative activation of water obtained by high voltage electrical pulses in a solution of NaOCl in water.
- the sterilization process corresponds to a chemical reaction of the M + S - »P type, where M denotes micro- organisms, S the sterilizing chemical molecules, P the resulting chemical, the corresponding concentrations being [M], [S] and [P].
- [M] is the concentration of microorganisms at time t, and [M] 0 their concentration at time zero.
- K is the reaction rate constant
- K 0 is a factor characterizing the type of process and its components
- W is the energy of the reaction
- k is the Boltzmann constant
- T is the temperature of the medium.
- ⁇ W The limit value of ⁇ W can be estimated as follows:
- FIG. 10 illustrates the influence of the degree of activation on the number of surviving microorganisms, as a function of the time of exposure.
- Waters BW; L, BW2, BW3, BW4 correspond to increasing values of field current and voltage imposed on water, for a constant concentration of disinfectant chemical (in this case NaOCl).
- FIG. 11 illustrates the "aging" of the activated water, due to the degradation of the activation state of the medium. This degradation can be represented analytically in the form of
- K being the reaction constant at time t, K 0 its initial value and T 0 , the degradation period.
- the liquid is made up of polar molecules.
- the maximum energy to bring to the liquid to decompose the clusters is equal to the average energy of attraction of the molecules of the liquid agent, which corresponds to the state of the liquid for which the clusters are completely disintegrated into molecules. This energy can be expressed as [7]:
- E is the value of the electric field voltage
- j the current density
- t the duration of application of the electric field
- the minimum energy ⁇ W ⁇ to bring to the liquid is that necessary to tear off a single molecule from the clusters, This energy is difficult to calculate but, in any case, is infinitely small, compared to the energy of total disintegration of the clusters.
- Wi is the absolute value of the minimum modification energy of a cluster
- W2 is the energy necessary for the maximum modification of the cluster, or the average energy per molecule spent for the total disintegration of clusters
- the coefficient ⁇ represents the fraction of the total energy supplied to the liquid agent by the electric current, corresponding to the inelastic interactions of cations and anions with the clusters. This coefficient can be calculated as
