    164) PLANT FOR THE TREATMENT OF WATER FOR PHYTOSANITARY USE OR FOR WATERING.
    FR 3 062 646 - A1
    16 /) Installation for treating (1) water, in particular for agricultural use such as for phytosanitary treatments and / or for the supply of water to farm animals and / or for the use of water supply for human needs, comprising an inlet (11) for water not yet treated, demineralization means (3) downstream from the water inlet, at least one water circuit (12) starting from the inlet (11) and passing through the demineralization means, as well as, arranged downstream of the demineralization means (3) and in connection with the water circuit (12), measuring means ( 60) of the pH of the water and means of regulating (70) the pH of the water to adjust the pH to a determined value as a function of the pH measurement, characterized in that it comprises, in connection with the water circuit (12), means (61) for measuring the conductivity of the water and means (71) for regulating the conductivity at a determined value.

    The invention relates to the field of water treatment, in particular for agricultural use such as for phytosanitary treatments and / or water supply for farm animals, and / or for water supply use for human needs.
    The invention will be described more particularly with regard to a unit installation for treating water intended to be used either for diluting phytosanitary products, or for being distributed to farm animals or intended for human consumption. Thus, from a single installation, the installation of the invention makes it possible to select a treatment for a particular application from advantageously three possible treatment choices. However, the invention could design three installations independent of each other, each assigned to a particular application.
    Concerning an application in phytosanitary treatments of soils and / or crops, in the usual way, the phytosanitary products sold are to be diluted beforehand in water. In order to ensure a good dissolution or dilution of the phytosanitary product in water, the product manufacturers have established recommendations for each phytosanitary product as to the maximum quantity of product to be mixed per liter of water, the pH of the water and the water temperature to ensure mixing.
    It is recognized that the pH of water affects the ability of the active ingredients in the product to dissolve in water. However, the pH of water is variable depending on the type of water used (well water, well water, spring water, mains water supply, etc.), and where it comes from.
    In order to provide water whose pH is controlled to ensure an appropriate mixture of phytosanitary products in water, the European patent
    EP 2 089 158 B1 proposes a device comprising means for demineralizing water and adjusting the pH.
    However, despite a good dissolution of the product, it very often turns out that the grower uses far too much water and sometimes even excessive doses of phytosanitary product, to make, according to him, more effective the absorption by plants of the mixture phytosanitary.
    In order to optimize the quantity of water to be used for the phytosanitary mixture, it has recently been demonstrated that the size of the droplets of projection of the mixture on the crops has an influence on the quality of absorption of the plants. For this purpose, it is then necessary to adapt the diameter of the mixture distribution nozzles during the spreading of the phytosanitary treatment. However, this effective technique is implemented after the product has dissolved in water. To further optimize the amount of water required for a phytosanitary treatment, the invention aims to propose a technical solution upstream of the dissolution of the product and with regard to the water used for this dissolution.
    Furthermore, the device for demineralizing water and adjusting the pH, proposed by the aforementioned European patent, is only dedicated to the treatment of water for phytosanitary use.
    Many farms combine cultivation (land and / or fruit trees, vines) and animal husbandry. With regard to animal husbandry, watering is a key element in the success of animal production, the quality of water having important repercussions on animal health and production. The most common problems with water quality are the excessive concentration of minerals, sulfates, nitrates or nitrites, contamination of the water with bacteria, and the presence of biofilms (green algae) with the risk of their significant proliferation. In addition, it has been shown that the degree of pH of the water and the rate of mineralization have an impact on the quality of production, and that in addition these parameters are preferably to be adapted according to the species raised.
    The object of the invention is therefore to propose an installation for treating water, the water of which, once treated, has optimal characteristics to ensure not only good dissolution of plant protection products, but also can lead to the best reduction of the quantity of water necessary for an effective phytosanitary treatment. Incidentally, the invention aims to provide an installation dedicated to several uses of the treated water which will be implemented selectively and individually on request, the treated water being adapted to each of the uses such as for phytosanitary use or for drinking.
    According to the invention, the installation for treating water, in particular for agricultural use such as for phytosanitary treatments and / or for supplying water to farm animals and / or for using water supply for human needs, includes an inlet inlet for water not yet treated, demineralization means downstream from the inlet inlet for water, at least one water circuit starting from the inlet and passing through the demineralization means, as well as, arranged downstream of the demineralization means and in connection with the water circuit, means for measuring the pH of the water and means for regulating the pH of the water for adjust the pH to a determined value based on the pH measurement. The installation is characterized in that it comprises, in connection with the water circuit, means for measuring the conductivity of the water and means for regulating the conductivity at a determined value.
    In the following description, the terms “upstream” and “downstream” are to be understood by qualifying the elements of the installation according to the direction of water circulation from an untreated water supply inlet up to a discharge outlet for treated water or an element receiving treated water.
    Consequently, the water treatment installation of the invention is able to supply demineralized and treated water having not only a suitable pH but also a controlled conductivity.
    Thus, in a phytosanitary application, it turned out that the control of the conductivity of the water makes it possible during the spreading of the water / phytosanitary product mixture to optimize the penetration through the plants of the phytosanitary product diluted in l and minimize the evaporation of the mixture.
    The consequence is the minimization of the volume of water used for an effective phytosanitary treatment. For example, thanks to the installation of the invention, it is possible to reduce by a factor of three, or even four, the amount of water required for a phytosanitary treatment compared to the amount of water used from 'untreated water, that is to say water whose at least the pH and conductivity are not controlled.
    The treatment plant of the invention therefore makes it possible to control the consumption of water useful for a phytosanitary treatment, water consumption being today a major concern within the framework of sustainable development.
    In an animal watering application, the measurement and regulation of the conductivity advantageously results in the supply of sufficiently chlorinated water to prevent the development of biofilms.
    Note that the term "conductivity" of water in a watering application is most often called "electrolysis" of water, the so-called electrolysis values (watering application) being much lower than the values of conductivity (phytosanitary treatment application). The "electrolysis" of water for watering is generally generally at most 1000 Siemens while it reaches for example 1500, even 2000 Siemens for phytosanitary treatment.
    Finally, the installation can incidentally be used to treat water for humans, the water being disinfected to be potable by bactericidal means, in particular by ultraviolet light.
    According to one characteristic, the installation comprises, in connection with the water circuit, means for measuring the water temperature and means for heating the water temperature to a determined value.
    Thus, in a phytosanitary application, it is guaranteed to provide water at the appropriate temperature to ensure optimal mixing of the phytosanitary product with the treated water, the temperature being that recommended for said product.
    Advantageously, the installation comprises at least one water storage tank connected downstream on the water circuit, to said demineralization means, preferably the installation further comprising, arranged between the demineralization means and the tank , means for opening / closing the water circuit such as a solenoid valve, and a volumetric counter for the quantity of water to be conveyed into the tank, and in that the water circuit makes a closed loop from of the tank.
    The volumetric meter allows the volume of water just necessary for the phytosanitary treatment envisaged by the cultivator to be taken, and only the volume stored in the tank will be treated in a closed loop.
    Advantageously, the treatment installation of the invention further comprises
    - a pump connected at the outlet of the tank to convey the water from the tank into the closed loop,
    - the water heating means such as a boiler, which are arranged downstream of the pump,
    the means for measuring the pH, the conductivity and the temperature which are arranged on the closed loop downstream of the heating means, and
    the means for regulating the pH and the conductivity which are connected to the closed loop downstream of the said means for measuring the pH, the conductivity and the temperature, the water being intended to be treated via the said means for regulating the pH and conductivity before returning to the tank.
    According to one characteristic, the installation comprises additional means of demineralization relative to the first means of demineralization, the additional means being implemented in addition to the first means of demineralization when the volume of water to be treated simultaneously is greater than the volume which is suitable to be treated by said first demineralization means.
    According to another characteristic, the installation is dedicated to water treatment for using the treated water for mixing with a phytosanitary product, and incidentally and as a replacement (of a treatment for a phytosanitary application) dedicated to a treatment for a water supply for farm animals, the installation for watering animals which can incidentally be used for water supply for human needs.
    In this latter application for water for drinking (breeding), the installation further comprises downstream demineralization means,
    - means of remineralization,
    - Preferably a member for opening / closing the water circuit which is arranged between the demineralization means and the remineralization means,
    - bactericidal means, such as means of ultraviolet treatment, and the installation is characterized in that
    the means for measuring the pH and the conductivity are arranged downstream of the bactericidal means, and
    the means for regulating the pH and the conductivity of the water are arranged downstream of the means for measuring the pH and the conductivity.
    According to a characteristic of the installation for treating drinking water, the water circuit comprises a loop, possibly implemented (that is to say not necessarily implemented according to the type of need), return of the water between the means for regulating the pH and the conductivity and the means for measuring the pH and the conductivity, the loop being implemented only if it is necessary for the water to have a pH and a determined conductivity and until the pH and conductivity values have reached the determined values. This return loop is implemented according to the type of watering for the animals, that is to say according to the type of breeding. For example, it is not used for cattle. In addition, it has never been implemented for human needs.
    This latter installation includes an outlet for discharging the treated water downstream of the return loop. Means for opening the discharge outlet are provided and are used (to generate the opening) when the pH and conductivity measurements correspond to the expected values. The control of these opening means is ensured via the programming and control interfaces for pH and conductivity which have received and processed the measurement information for pH and conductivity. If the return loop is not implemented, compliance with pH and conductivity not being necessary for the intended application (human need for example or watering cattle), the opening means are automatically activated works to open the drain outlet when no pH and conductivity value has been programmed.
    In a particular embodiment of the water treatment installation, the installation comprises at least two water circuits downstream of the demineralization means, the two water circuits not being implemented concomitantly , and the installation comprising on the first circuit a water storage tank connected to said demineralization means, said first circuit forming a closed loop for treating water from said tank, while the second circuit comprises means remineralization, bactericidal means such as ultraviolet treatment means, and at the downstream end an outlet for discharging the treated water.
    According to a characteristic of the aforementioned installation with two independent functions, the two water circulation circuits comprise (meet to comprise) a common part to which are connected on the one hand the means for measuring pH and conductivity and possibly means for measuring the temperature, and on the other hand the means for regulating the pH and the conductivity. The common part is located just after the heating means of the first circuit and the bactericidal means of the second circuit.
    Downstream of the pH and conductivity regulation means and upstream of the discharge outlet for the treated water, the first circuit continues with a closed loop to reach the storage tank, while the second circuit continues by a return loop possibly implemented and connected between the bactericidal means and the means for measuring pH and conductivity.
    Furthermore, the demineralization means of the installation include cationic ion exchange resins, in particular for removing the cations Ca 2+ , Mg 2+ , Fe 2+ , Fe 3+ , Al 3+ , Zn 2+ .
    Advantageously, the installation includes additional means of demineralization which are implemented to replace the first iso demineralization means when the latter must be cleaned.
    Preferably, the installation comprises, upstream of the demineralization means, filtration means having a filtration power of the order of at least 25 μm, preferably at least 3 to 5 μm, such as a filter of the sand type.
    The installation includes interfaces with the user comprising means for programming the volume of water, programming and controlling the pH, means for programming and controlling the conductivity, and optionally means for programming and controlling the temperature, said programming and control means comprising display means for the user in the form of display screens with buttons and / or tactile programming keys.
    Advantageously, the installation is housed in a container or local, thermally insulated, capable of being closed, and comprising programming and control interfaces for the pH of the water, the conductivity of the water, and possibly the programming. of the volume of water to be treated, and optionally of programming and controlling the temperature, preferably at least said interfaces for programming and controlling the pH of the water, the conductivity of the water, and possibly the programming of the volume of water to be treated are grouped on a panel for the user, and preferably the installation comprising a general switch for starting and stopping the installation.
    The present invention is now described with the aid of examples which are only illustrative and in no way limit the scope of the invention, and from the attached illustrations, in which:

    The installation 1 of the water treatment invention, which is schematically illustrated in FIG. 1, is dedicated exclusively to the treatment of water intended to be used to be mixed according to π
    optimal conditions with a phytosanitary product, the water must have at least a pH and a conductivity adapted to the type of phytosanitary product, and preferably also have an ad hoc temperature to promote mixing.
    The user (the farmer), depending on the type of sanitary product, will program the desired values of pH, conductivity and temperature at the installation level, to obtain treated water at the outlet of the installation with the programmed pH, conductivity and temperature values.
    The pH and the temperature are parameters whose values vary according to the nature of the plant protection product and are supplied by the product manufacturers. The farmer thus knows the pH and temperature values to program.
    The conductivity is provided to the farmer by data tables mentioning the preferred value of the conductivity depending in particular on the type of leaf mass or the type of plant to be treated, the temperature and the humidity of the external environment. The conductivity to be programmed will for example be different for a temperate environment and a much warmer, even arid environment. In particular, such data tables have been drawn up by the applicant himself.
    The treatment plant 1 shown diagrammatically in FIG. 2 makes it possible to carry out a treatment of water for the use of watering animals or human needs.
    The treatment installation 1 shown diagrammatically in FIG. 3 makes it possible to carry out a water treatment either for the phytosanitary application, or for the use of watering animals or human needs. Consequently, the installation of FIG. 3 corresponds to the installation of FIG. 1 with additional means of treatment dedicated to the application of watering animals or humans (means which are found on the 'installation of Figure 2), the implementation of the two applications is not concomitant but each of them being able to be selected independently of one another.
    According to the invention, the installation 1 can be arranged in a thermally insulated room.
    In a preferred embodiment, the installation is housed in a deliverable container C ready for use, as illustrated in FIGS. 4 and 5.
    Most often, container C will be installed in an outdoor farm. Also, the container is preferably thermally insulated and may include heating means 10 (FIG. 5) for heating the ambient air inside the container when the latter is closed in order to keep the entire installation cold, in particular the elements / electrical and / or electronic equipment.
    With reference to FIGS. 1 and 5, the water treatment installation 1 of the invention for phytosanitary use comprises an inlet for untreated water 11, a circuit for routing water 12 through different elements described below to ensure water treatment.
    From entry 11, installation 1 comprises on circuit 12
    - water filtration means 2;
    - demineralization means 3 of the water connected to the outlet of the filtration means 2;
    - possibly additional means 30 of demineralization similar to the first demineralization means 3 of water to treat a larger volume of water;
    - opening / closing means 13 of the circuit 12 such as a solenoid valve, located downstream of the demineralization means 3 and additional demineralization means 30;
    - Means for counting 14 the volume of water to be treated, such as a volumetric counter, arranged just after the solenoid valve 13;

    - a pump 40 for pumping water from the storage tank 4;
    - Water heating means 5 which are connected downstream of the pump 40, and which constitute means for regulating the temperature;
    - downstream of the heating means 5, means 60 for measuring the pH, means 61 for measuring the conductivity (μ), means 62 for measuring the temperature (Θ);
    - Downstream of the measuring means 60 to 62, means of regulation 70 of the pH of the water and means of regulation 71 of the conductivity of the water.
    In addition, the installation 1 of the invention comprises, as illustrated in FIG. 6, a panel P on which are advantageously arranged a control member 15 for starting and stopping the installation, such as a On / Off switch, and programming and control interfaces 16 to 18 for the user, which will be detailed later in order to program the volume of water to be treated, and control the desired pH and conductivity for the water to be treat.
    The panel P will be accessible by the user inside or outside the container C depending on the location of the container in its end use.
    Thus, the user can easily carry out his programming as to at least the pH and the conductivity of the water to be treated.
    The water filtration means 2 are intended to retain impurities. They are, for example, in the form of a sand filter, or else a so-called "sock" filter. The filtration cutoff has a threshold of the order of 5 to 25 pm, preferably is of the order of 3 to 5 pm. In addition, rinsing means 20 of the sand filter are provided, which are connected to said filter 2, the filter 2 being connected to an external outlet (not shown) for discharging the rinsing water. The rinsing means 20 of the filter are of the type known per se.
    The water demineralization means 3 consist for example of a container having a filter on a bed of cationic ion exchange resins which are capable of removing several chemical elements including at least the following cations Ca 2+ , Mg 2+ , Fe 2+ , Fe 3+ , Al 3+ , Zn 2+ .
    The additional demineralization means 30 constitute a second container identical to the container of the first demineralization means 3. A bypass of the circuit 12 is provided at the demineralization means 3 and connected to the additional demineralization means 30. The additional demineralization means 30 are used when it is necessary to treat a volume of water greater than that which the container of the first demineralization means 3 can treat. The container of the first demineralization means 3 is then switched off once a first volume of water has been treated and is cleaned while the container of the additional means 30 plays its role.
    The pump 40 makes it possible to pump the water from the tank 4 and to inject it onto the rest of the circuit 12, which forms a closed circulation loop 12A from the tank 4.
    The water heating means 5 are, for example, a boiler. A thermostat 50 is provided associated with the heating means to regulate the temperature. The thermostat 50 and the heating means 5o form the means for regulating the temperature of the water to be treated.
    The heating means 5 operate as long as the temperature measured by the measuring means 62 on the water circuit has not reached that programmed in the thermostat 50.
    Thermostat 50 directly constitutes the programming interface for the temperature desired by the user. This thermostat could be connected to a display interface for the user on panel P on which the other interfaces for pH and conductivity are arranged.
    The means 60 for measuring the pH (a probe 60A for measuring pH + and a probe 60B for measuring the pH), the means for measuring the conductivity (a probe for measuring the conductivity), the means 62 for measuring the temperature (a temperature measurement probe), are preferably grouped locally on the circulation loop 12A. The measurement probes are known per se.
    The regulation means 70 for the pH and the regulation means 71 for the conductivity are placed just after the measurement means 60 for the pH, 61 for the conductivity, and 62 for the temperature.
    The pH measurement means 60 are connected to the pH programming, calculation and control interface 17 which themselves are connected to the pH regulation means 70.
    Depending on the water treatment, the pH of the water must be neutral (pH = 7), or basic (pH> 7) or acidic (pH <7). The pH regulation means 70 comprise, in a known manner, two reservoirs 70A and 70B, respectively of an acid and a base, and metering and injection pumps 70C and 70D, on the one hand connected to each reservoir, respectively 70A and 70B, and on the other hand connected to the loop 12A of the water circuit 12 to inject into the circuit, acid if the pH measured is basic or not acidic enough, or base if the pH measured is acidic or not basic enough, or to adapt the pH to 7.
    The means 70 for measuring the conductivity of the water are connected to the programming and control interface 18 for the conductivity which receives the measurement information, said interface 18 being connected to the means 71 for regulating the conductivity of the water. the water.
    The means 71 for regulating the conductivity of the water comprise a metering and injection pump 71A connected to the loop 12A of the circuit 12, chlorine delivery means 71B which are connected to the metering pump 71 A. Preferably, the chlorine delivery means 71B form part of an apparatus for transforming sodium chloride into chlorine, such as by electrolysis. Such an apparatus is known per se. A sodium chloride tank is provided to supply the apparatus for converting sodium chloride into chlorine.
    Once the basic or acid injection has been carried out to regulate the pH as a function of the pH measurement, then the injection if necessary of chlorine on the water circulation loop 12A as a function of the measurement of the conductivity, the treated water returns to the storage tank 4 and is re3062646 pumped via the pump 40 to continue to be heated if necessary and to undergo again the successive measurements of pH, conductivity and temperature. As long as the pH, conductivity and temperature measurements do not correspond to certain values, the circulation loop 12A is operational.
    When the determined values of pH, conductivity and temperature are reached, the pump 40 is switched off and the treated water remains in the storage tank 4. The treated water from tank 4 then has the ad hoc characteristics of pH, conductivity and temperature to be directly used to be mixed with a phytosanitary product for which the recommendations for pH, conductivity and temperature of the mixing water are identical.
    Except for the storage tank 4 and the water heating means 5 which are arranged outside the room or container C, all of the other aforementioned elements of the installation 1 are arranged in the room or container C.
    The installation can comprise several storage tanks 4 as illustrated in FIG. 4, bypass means being provided for supplying and treating in loop the water from a second tank when the water from the first tank has been treated, and so on for the other tanks.
    The control member 15 (FIG. 6) for starting and stopping the installation, such as an on / off switch, allows the operation of all the elements of the installation operating with electricity, except on / off control of the display and programming plate 16 of the volume of water to be treated.
    The programming and control interfaces 16 to 18 of the installation include display and programming means 16 of the volume of water to be treated, display and programming means 17 for the desired pH of the water after treatment, and display and programming means 18 of the desired conductivity of the water after treatment.
    The display and programming means 16 of the volume of water to be treated are connected to the volumetric meter 14. Depending on the volume of water programmed to be treated, the solenoid valve 13 will be open to fill the tank 4 and then closed when the meter volumetric 14 will have reached the desired volume.
    The pH display and programming means 17 receive the measurements from the pH measurement means 60 and are connected to the pH regulation means 70, more particularly to the metering pumps 70C and
    70D of pH. Preferably, two plates 17A and 17B are provided for independently adjusting the pH, when it is respectively necessary to regulate either a basic pH (pH + ) or an acidic pH (phT). Each plate 17A, 17B is respectively connected to each of the metering pumps 70C and 70D.
    Only one of the two plates 17A and 17B is used since it is a question of adjusting the water, either to a basic pH or to an acidic pH.
    The presence of two plates provides security for the user in the event of a failure of one of the two plates. Indeed, in case of failure, for example of the basic pH platinum, the other acidic pH platinum can be implemented by programming the desired pH to a basic value (and not acidic), while making sure to disconnect this circuit board of the metering and acid injection pump, and reconnect it to the basic metering and injection pump.
    As for the programming of the conductivity, the board 18 makes it possible to display and program the desired conductivity. It receives the conductivity measurement carried out by the measuring means 61, processes the information as a function of the conductivity to be reached and controls the means for regulating the conductivity 71.
    When the determined values of pH, conductivity and temperature are reached, the control interfaces 16 to 18 and the thermostat 50 trigger the stop of the pump 40, the stop of the dosing and injection pumps of pH 70C, 70D and chlorine 71 A, stopping the electrolysis treatment apparatus, and heating means 5.
    The operation of the treatment installation in FIG. 1 dedicated to a phytosanitary application is as follows. The user programs the volume of water to be treated on the plate 16, then presses the on / off button 15 to start the installation 1, programs the desired pH value either on the plate 17A or on the board 17B according to the desired basic or acidic pH value, programs the desired conductivity value on board 18, programs the desired water temperature on thermostat 50, and finally presses a start switch 19 on the pump 40 which can be programmed with delayed start. The tank 4 is filled according to the programmed volume, the pH and the conductivity are adjusted according to the desired values, the boiler makes it possible to regulate the temperature according to the desired value, and the pump 40 allows the water to circulate in the installation. .
    Pump 40 and the boiler stop as soon as the pH and conductivity probes detect that the values reached correspond to the requested programming.
    The installation 1 of the invention described above with reference to FIG. 1 was exclusively reserved for water treatment for phytosanitary use.
    With reference to the diagram of FIG. 2, an installation with an exclusive watering function is now described.
    We find in common with the treatment installation of Figure 1, the water inlet 11, a water supply circuit 12, the filtration means 2 with the rinsing means 20, the means of demineralization 3 and possibly additional ones 30, as well as the means 60 for measuring the pH, the means 61 for measuring the conductivity μ, and the means for regulating 70 the pH and 71 for the conductivity.
    îo Furthermore, the installation of FIG. 2 comprises, in common with the installation of FIG. 1, the interfaces which are the control member 15 (FIG. 6) for starting and stopping the installation, such as an on / off switch, display and programming boards 17 for pH and 18 for conductivity.
    Note that the programming of the conductivity can be fixed by being carried out in the factory during the manufacture of the installation, or by a technician during the commissioning of the installation at the farmer's, or even be adjusted by the farmer.
    In addition, the treatment installation of FIG. 2 for watering use, comprises just after demineralization means 3, an opening / closing member 8 of the water circuit 12, such as a manual tap, remineralization means 9, bactericidal means 90 making it possible to destroy the bacteria present in the water, such as ultraviolet treatment means, and an outlet 11A for the treated water.
    Advantageously, the installation comprises a return loop 12B of the water circuit 12 which starts from a connection point 12C situated between the means of regulation 71 of the conductivity and the outlet 11 A, and which joins the water circuit at a connection point located between the bactericidal means 90 and the means 60 for measuring the pH and 61 for the conductivity.
    The remineralization means 9 are for example a container into which is injected with demineralized water, a portion of the raw water filtered before the demineralization step (symbolized in FIGS. 2 and 3 by line 91).
    The bactericidal means 90 are for example an apparatus with ultraviolet lamps. Such an apparatus is known per se.
    Diversion means, with a double pipe, are provided at the connection point 12C to allow water to pass either to the return loop 12B or to the outlet 11 A.
    The operation of the installation in FIG. 2 is as follows.
    The user programs the pH of the water and the conductivity according to the type of watering. For example, the values will be different for chick rearing and calf rearing.
    The user opens the member 8 for the passage of the water which has undergone demineralization via the demineralization means 3. The water then passes through the remineralization means 9 then through the bactericidal means 90. The pH measurements and conductivity are then carried out by the measuring means 60 and 61 to be transmitted to the programming and control interfaces 17 and 18 respectively, which in turn control the means 70 for regulating the pH and 71 for the conductivity.
    At the output of the means for regulating the pH 70 and the conductivity 71, the water circulates (if necessary) through the return loop 12B, as long as the determined pH and conductivity values are not reached.
    When the values are reached, the water is directed to the outlet 11 A. When the values are reached, the programming and control interfaces 17 and 18 stop the means of regulation 70 of the pH and 71 of the electrolysis, and the measuring means 60 and 61.
    If there is no need for regulation of the pH and of the conductivity, the means of regulation 70 of the pH and 71 of the conductivity, and the measuring means 60 and 61 are not used; the water at 12 C is directed to exit 11A.
    Finally, with regard to the diagram in FIG. 3, the installation 1 of the invention îo comprises the function for phytosanitary use and the function for watering use, the two functions not being able to be implemented concomitantly.
    The elements common to the installations of FIGS. 1 and 2 are referenced in the same way.
    Downstream of the demineralization means 3 and 30, the circuit 12 is divided into two circuits 120 and 121, called respectively phytosanitary application circuit and watering application circuit, to join upstream of the pH measurement means 60 , 61 of the conductivity and 62 of the temperature.
    On the first phytosanitary application circuit 120, the solenoid valve 13, the counter 14, the storage tank 4, the pump 40 and the heating means 5 associated with the thermostat 50 are arranged.
    On the second watering application circuit 121, the opening / closing member 8, the remineralization means 9 and the bactericidal means 90 are arranged.
    The two circuits 120 and 121 meet because the measurement probes are common to the two circuits. The water passes through one or the other circuit according to the intended application, then the parameters of pH, conductivity and possibly temperature are measured by the same means 60 to
    62 whatever the application.
    The regulating means 70 and 71 are downstream from the measuring means 60 to 62 while being on the common water circuit. They are checked in the same way as explained above for each of the applications.
    At the outlet of the regulating means 70 and 71, the water circuit 12 splits iso in two to on the one hand form the closed loop 12A which returns to the storage tank 4, and on the other hand form the return loop 12B which joins the circuit 121 between the bactericidal means 90 and the means 60 for measuring the pH and 61 of the conductivity.
    Two pipes are arranged at the outlet from the regulating means 71 to form the respective loops 12A of the phytosanitary treatment water circuit and 12B of the watering circuit. On the pipe of the circuit 12 A, and immediately downstream of the regulating means 71, the outlet 11A is arranged for the treated water for watering.
    Depending on the desired use, the user will implement one or the other of the applications, each of them functioning as indicated above.
    Incidentally, the installation of Figures 2 and 3 allows when it is not used for a phytosanitary application, or for watering animals, to be used for human needs. The member 8 is then open, the return loop 12B does not need to be implemented. There is no need to control the pH, the conductivity, or the temperature, the water after remineralization passes through the bactericidal treatment means 90 (ultraviolet) and leaves the installation directly via the outlet
    AT.
