Abstract

The present invention relates to a novel method for completely disinfecting bathing pools with natural water regulation, alternately during the day and night, in a manner which is discontinuous and instantaneous by mass effect with n injections of limited number, the volume of each injection being defined by the experimental function C*fn,e(X), allowing an optimum night-time disinfection to be achieved with natural daytime regulation in compliance with the permitted disinfection rate, eliminating the need for physico-chemical checks on the water, and allowing the process to be controlled with a single synthesis parameter by means of a preferential device [Fig. 12] which may or may not be supplied with autonomous energy, and which comprises a box (19) of connected and/or manual controls, such as the programming commutator (82) and the multi-way valve (81), automatically controlling by compressed air, in situ or remotely, the metering operations by static gauges (105), which are specific to the method, with a volume pre-adjustable by means of a rule (10) and/or by parametrising n.

Description

global disinfection process with natural regulation of the waters of swimming pools

Field of invention

The present invention relates to a new global disinfection process with natural regulation of the water in swimming pools, which is based on a treatment, alternating day and night, of the discontinuous and instantaneous type defined in volume by the experimental function C*fn,e(X), implemented by a preferential device which makes it possible to control the entire process with a single parameter, on site or remotely.

State of the prior art

[0002] The different types of current processes for the disinfection and automatic or semi-automatic regulation of bathing pools are based on a continuous and infinitesimal treatment of the water which circulates in a loop by suction of the water at the level of the pool and by discharge into the basin of the latter filtered, disinfected and regulated so as to disinfect and indirectly stabilize the total mass X of water in the basin which is then subject to internal and external disturbances of the environment of the basin.

In these types of treatment, there are two main functions of filtration with respect to disinfection. In addition to setting the water in motion, the first consists in filtering the water to eliminate particles or debris suspended in the water and the second consists in making the disinfectant from the water set in motion by the filtration of so as to treat the water continuously and in an infinitesimal quantity per unit of time according to the duration of the filtration which is empirically determined in hours by the following formula, filtration time equal water temperature divided by 2.

Also this disinfectant action compared to the volume of water and to the surface of the basin, on the one hand is of great inertia in the face of rapid and strong disturbances such as variations in solar radiation, the temperature of the water, Ph following stormy weather, active disinfectant content following over-frequenting of the pool and on the other hand maintains a phenomenon of habituation of viruses and algae to disinfectants by this type of continuous valuable treatment infinitesimal.

[0005] Under these conditions, to respect the quality of the water, these types of treatment must, on the one hand, reinforce their disinfecting action by using a stabilizer to maintain a persistence of the disinfectant with respect mainly to the action of solar UV to which the pool is directly exposed and on the other hand to regulate in synchronization the following five physico-chemical parameters of the water, namely the Ph, the content of active disinfectant linked the filtration time depending on the temperature of the water with an efficiency limit for this type of treatment generally accepted beyond 28 degrees, the alkalinity (TAC), the hardness (TH) and the stabilizer content.

[0006] Also, these conventional devices do not make it possible to easily identify the causes of poor water resistance because this mainly requires the control of the bounded value of each of the five water parameters, nor to correct instantly on site or remotely the consequences of malfunctions or disturbances in the environment such as a transfer of pool water because this type of continuous and infinitesimal disinfection is by its principle of great inertia, nor to anticipate in directly modifying the disinfection parameters remotely, for example to deal with unplanned overcrowding of a pool over a long period.

[0007] These systems cannot be supplied with independent electrical energy such as solar energy because the production of the disinfectant action in the disinfection circuit and the automatic regulation of the water parameters are very energy-intensive.

[0008] In addition, the technical complexity of the devices for manufacturing the disinfectant and regulating action leads to malfunctions depending on their degree of wear, the aggressiveness of the products used and the characteristics of the water to be treated. These various devices therefore require, for reliable operation, both ongoing maintenance and upkeep.

[0009] This is why these systems lead to excessive disinfection and filtration time compared to the real need of the pool and given the number of parameters to be controlled, they cannot be solved, simply and economically on site or remote control of the disinfection and regulation of bathing pool water, both by customers and by professionals.

Disclosure of Invention

The present invention relates to a new global disinfection process with natural regulation of the water in bathing pools which is based on a direct treatment of all X of the water in the pool, alternating day and night, of the discontinuous type. and instantaneous volume defined by the experimental function C*fn,e(X) and in that one distinguishes on the one hand a disinfection phase carried out at night which consists in treating the pool water with a specific disinfectant product under form of a series of doses in a limited number n each with an optimal mass effect and fixed volume determined by the function C*fn,e(X) and on the other hand a phase of natural regulation of the disinfection carried out during the day, mainly by the action of solar UV rays which gradually degrade the disinfectant product accumulated during the night and this approach in two phases makes it possible to target and control by a single fixed synthesis parameter, the progress of the entire process carried out from a preferential device [Fig. 12] which carries out the piloting of the process using on the one hand a box (19) equipped with secure and connected automatic and/or manual commands and controls and an air compressor and on the other hand process-specific static gauges [Fig. 6] and other accessory functions to bathing pools, these gauges being manually pre-adjustable in secure volume and supplied by tanks [Fig. 9] containing the different disinfectant products and accessories.

Summary of the invention

[0011] The disinfectant products used in the process are of the biocide type, associated or not, with accessory products for bathing pools which are mainly comfort products without biocidal properties.

The disinfection phase is carried out at night, by applying the linear or non-linear experimental functions which give the fixed volume C*fn,e(X) of the dose of disinfectant product to be injected n times, each making it possible to reach one of the optima for night disinfection.

[0013] The synthesis parameter is for a disinfectant product and a number n of injections, the fixed target value of the consumption of disinfectant product per night.

[0014] The natural regulation phase of disinfection is carried out during the day mainly by the action of solar UV rays while leaving enough active disinfectant to keep the water holding up to hygiene standards.

[0015] The filtration time is fixed and independent of the water temperature, since the disinfectant product is ready to use.

[0016] The natural regulation of the other parameters of the water is carried out thanks to the two phases, one of night disinfection and the other of day regulation, which by blocking the proliferation of bacteria, viruses and algae allow these parameters to gradually return to their initial average value.

[0017] The preferred device [Fig. 12] consists of a control box and static gauges. [0018] The box (19) controls the process on site or remotely, by connected and/or manual commands assisted by control and safety systems which, while managing the operation of the chosen static gauge, make it possible to check and adjust product consumption with the target value of the synthesis parameter and directly limit or correct the consequences of disturbances or malfunctions such as water transfer from a pool.

[0019] The static gauge [Fig. 6] is placed removable or not opposite the master tank (101 inside or outside and consists of the body (105) of the gauge which contains the product and the calibration and ejection system of the dose [Fig. 7] which makes it possible to manually preset and mechanically secure by its design the volume of the dose to be injected according to the function C*fn,e(X).

Detailed description of the invention

For the products used, a distinction is made between the disinfectant products used in the process and the accessory products relating to the swimming pools but independent of the process.

[0111] For disinfectant products, the words disinfectant and disinfectant product do not have the same meaning. The disinfectant constitutes the active agent of the disinfectant product which must be in the new process of the biocide type, not stabilized with solar UV, of remanence adapted to the process, ready to use mainly in liquid form, miscible in water quasi- instantly. We will use as an application F sodium hypochlorite in aqueous solution, the disinfectant agent of which is chlorine.

[0112] For accessory products, these are products using functions other than those used in C*fn,e(X) disinfection which are complementary to the process, such as so-called liquid covers which form a protective film on the water limiting the action of solar UV rays, algaecides, bactericides or products solely for comfort or pleasure such as additives for seawater pools or colorants for water aesthetics.

For the disinfection phase carried out at night, the device [Fig. 12] determines the volume of the dose from the experimental functions C*fn,e(X) in which one distinguishes on the one hand linear functions which are similar to a straight line with equation ((10/(e*n ))*C)*X such that [Fig. 1] and [Fig. 5] and on the other hand nonlinear functions such as [Fig. 4] and in that these functions give on the ordinate (108), for a specific disinfectant product, the volume C*fn,e(X) of the dose to be injected n times into the volume X of water defined on the abscissa (107) with, as parameters, an efficiency coefficient e of the disinfectant product, a mass effect coefficient C depending on the normality of the indoor and outdoor environment of the basin and a number n of fixed and different injections mainly according to two preferential types of Normal or Economic disinfection which correspond to the seasons characterized by a break in the average value of the sunshine and in that the instantaneity and the volume C* fn,e(X) of each dose injected makes it possible to reach one of the disinfection optima (39) [Fig. 2] independent of the water parameters up to the disinfectant efficiency limit temperature.

[0114] The dynamics due to the instantaneousness of the volume C*fn,e(X) of each injected dose accelerates the disinfection result (39) and (47) [Fig. 2] by increasing in an optimal and discontinuous manner according to the staircase function (24) the content of active disinfectant with each injection (54) of volume C*fn,e(X) which is added and the doses being spaced apart by a fixed duration, the content of active disinfectant stabilizes each time on a level (45) and these sudden variations caused by the series of n injections block the proliferation and the phenomenon of habituation of viruses, bacteria and algae to disinfectant products and that to optimize the result of the disinfection, the injections are preferably carried out sheltered from solar UV in the middle of the night by determining the starting signal for the injections (47) either fixed or configurable by the programmer (82) either automatically by the light sensor (59) which gives the start of night (7) and day (48) [Fig. 3].

For the use of sodium hypochlorite in aqueous solution, in the case of a temperate climate and a conventional internal and external environment, the experimental function ((10/(e*n)) *C)*X which becomes with the parameters e=l efficiency coefficient and C=10 ^-6 Mass effect coefficient, ((10/n)* 10 ^-6 )*X which is the volume of the dose to be injected which makes it possible to achieve one of the disinfection optima with the preferential number n of injections which is between 1 and 4 limits included, such as for example n=1 injection for an Economic disinfection mode and n=4 injections for a Normal disinfection mode and in that the unit of measurement of the volume of the dose is of the order of a micro compared to the volume X of the pool.

The nonlinear experimental functions C*fn,e(X) specific to disinfectants with nonlinear action, such as the function [Fig. 4], are not related to a particular equation except in certain sections for which linear or non-linear equations can be assigned. These experimental functions are used to describe the action of particular disinfectants applied to pool characteristics outside the normal range such as very exposed to the action of solar UV whose shallow surface is 50% greater than the total surface of the pool or pools of very large or very small volumes.

The synthesis parameter, independent of the parameters of the water under the same aforementioned conditions, has for a disinfectant product and a volume X given as a fixed value with K synthesis constant n*C*fn,e(X)= K*X which is the total volume of disinfectant injected per night for a pool volume X, which corresponds to (46) [Fig. 2], [Fig. 3] to one of the highest optima in active disinfectant content and allows optimal regulation of the disinfectant content during the day and in that the synthesis parameter gives the target value of the consumption of disinfectant product per night and for the functions linear its value is equal to n*((10/(e*n))*C)*X=(10/e)*C*X with K=(10/e)*C and in the particular case of F sodium hypochlorite in aqueous solution with the efficiency coefficient e=1 and the mass effect coefficient C=10 ^-6 for X measured in liters, K= 10' ⁵ .

[0118] The natural regulation phase of the disinfection carried out during the day is a function of the disinfection optimum (46) [Fig. 2] obtained by the cumulative volume of disinfectant product during the night n*C*fn,e(X) which, being not UV stabilized, is gradually degraded by solar UV, its content of active disinfectant dropping from the maximum ( 46) [Fig. 3] at the beginning of the day (48) to then decrease to a minimum (12) at the end of the day where it stabilizes away from solar UV until the new injections of disinfectant with mass effect of the night following and in that the function n*C*fn,e(X) takes into account, by the coefficient e of efficiency, the degression of the content of active disinfectant in order to optimize in a natural way according to the curve of decrease ( 14) [Fig. 3] throughout the day the content of active disinfectant in such a way as to maintain the behavior and hygiene of the water and in that the day-to-day variations in the content of active disinfectant also contribute to limiting the phenomena of habituation from microbes and algae to disinfectants [Fig. 3].

[0119] With regard to the natural regulation of water parameters when these deviate from their average value following a disturbance of the internal or external environment of the pool, the night disinfection process associated with the natural daytime regulation, blocks the proliferation of microbes and algae and allows the water parameters to self-regulate by gradually returning to their average value, without noticeable deterioration in water quality during this transitional period.

The filtration time is fixed and independent of the temperature of the water under the aforementioned conditions, since on the one hand the disinfectant product used being ready for use, it is no longer made from moving water as a function of the filtration time and since on the other hand the consumption of disinfectant product is fixed, with the target value of the synthesis parameter.

[0121] The device [FIG. 12] preferential consists of the box (19) and the static gauge of [Fig. 6] and [Fig. 8].

The box (19) powered with (5) by the network or solar panels comprises controls, manual or automatic connected or linked to the connected multifunction relay (9), which allow, on site or remotely from a mobile , a tablet or a computer, to control mainly the compressor (23) by the multi-channel programming switch (82) and by the multi-channel valve connected or not (81) the direction of the air under pressure towards the static gauge (105) chosen , to control the consumption of product, to adjust it by modifying the parameters of the programs of (82) such as the number n of injections and the periodicity of the injections, to directly correct the consequences of malfunctions or disturbances due to the environment, to secure the operating time of the compressor (23) by the timer (97) and to inform of power cuts by the connected multifunction relay (9).

[0123] The programming switch (82) manages the following different main modes such as on the one hand the preferential automatic disinfection modes Normal (93) or Economic (94) with the valve (81) which sends the air calibrated by ( 32) to (80) to empty the static gauge (105) of the C*fn,e(X) dose to the pool via (35) and on the other hand manually triggered modes such as the preferential mode (95) which allows on the one hand with the valve (81) towards (80) to test the volume of the dose either on site or remotely following a transfer of the water from the basin to instantly restore the quality of the water by the injection of series of n doses each of volume C*fn,e(X) with entry of the number n and on the other hand with the valve (81) towards (33) to direct the uncalibrated pressurized air towards the outside to perform pneumatic functions and finally a stop mode (92) and in that the water temperature sensor (13) automatically switches the programmer (82) to No rmal or Economy based on a configurable temperature threshold.

The programmer programs (82) relating to the automatic disinfection modes such as Normal (93) and Economic (94) have as parameters the starting signal (47) of the injections, the periodicity of the series of n injections, the number fixed and different number of injections depending on the disinfection mode chosen, the fixed duration of the compressor shutdown which allows the filling of the gauge static and defines the disinfection stages (45), the fixed duration of the operation of the compressor of the order of one minute which includes the delivery of the dose in a few seconds and the cleaning of the dose ejection system [Fig. 7] the rest of the time.

[0125] The static gauge [Fig.6] consists of the body of the static gauge, the calibration and dose ejection system, the assembly being placed opposite the master tank (101) fixed to the interior [Fig. 9] or externally or removable.

The body (105) of the static gauge, of shape adapted to the function C*fn,e(X) and of multiple volume of the function C*fn,e(X) for a maximum volume to be treated X, place positioned obliquely either inside the master tank (101) non-removably fixed [Fig. 8] or removable using the handle (72) [Fig. 6] which allows the passage of the body of the gauge (105) through the opening (1) of the master tank (101) and its vertical fixing held by the cap (51) either outside the master tank (101) [Fig . 6] fixed in a non-removable way and in that in both cases it is closed at its ends with the air inlet (8) at the level of the reserve (28) and the valve (30) at the level of the bottom ( 2) to optimize both the operation of the dose ejection system [Fig. 7] and the useful volume of disinfectant by reducing the volume of the reserve (3) and when the body (105) of the static gauge is inside the master tank (101) its fixing being done using the press- cable glands (115) and (116) [Fig. 8], the rule (10) becomes external to the master tank (101).

The dose calibration and ejection system [Fig. 7] which crosses the body (105) of the gauge containing the product along its length, implements the corresponding experimental function C*fn,e(X) by means of the section of the body (105) of the static gauge along its length [ Fig. 6] and [Fig. 11] and linearity [Fig. 6] or not [Fig. 10] of the graduations (11) of the ruler (10) calibrated according to the volume X for a fixed number n of injection and it consists of flexible, transparent pipes (36) and (61, connected by a connector (69) pierced with the orifice (6) bounded by a stop (18) and the volume between the orifice (6) and the stopper (79) being equal to the volume determined by the function C*fn,e(X), the dose calibration is done by positioning the flexible rule (10) on the graduation (11) of the volume X or of a sub-multiple by sliding the pipes (36) and (61) in the cable glands (115) and (116 ) [Fig. 8] or (111) and (112) [Fig. 6] or directly in the holes (25) and (26) when the body (105) of the gauge is immersed in the product, the micro leaks of disinfectant then recycling inside the master tank (101).

For the dose filling phase, secured by the valves (66) and (67), compressor stopped, when the body (105) of the gauge is located in the master tank (101) immersed in the produced, it is filled directly by gravity through the valve (30) protected from impurities by the filter (53) and when the body of the gauge is outside the master tank (101), it is filled indirectly through the pipe (70) connected to the filter (53) of the valve (30) and in that in these two cases the filling is ensured by the secure opening of the valves (30) and (50) which being positioned obliquely [Fig. 6], open at zero pressure thanks to the weight of the ball (118) and the return to atmospheric pressure of the body (105) of the gauge carried out both by the calibrated orifice (78) and the opening of the valve (50) accelerated by the calibrated orifice (119) which constitutes the design safety of the filling of the body (105) of the volume dose gauge C*fn,e(X).

For the delivery phase of the dose secured by the valve (50) and the cleaning phase, the compressor being in operation, the valve (30) closes by air pressure via (8) and the pipe ( 61) being closed by (117) on the one hand the emptying of the dose is done by the orifice (6) via (36) then (35) towards the basin and stops by mechanical stop when the level of the disinfectant reaches the level of the orifice (6) whatever the operating time of the compressor, which constitutes the design safety of the delivered volume C*fn,e(X), then on the other hand this phase is followed by cleaning at the pressurized air which prevents the clogging of the safety valve (50) and the atmospheric pressure orifices (78), (119) by residues or by the chemical reaction of calcification at (35) between the disinfectant and the water to be treated. These two phases integrate the two design safety features of the volume of the injected dose of volume C*fn,e(X).

[0130] The master (101) and slave (40) tanks [Fig. 9] interconnected by (114) contain the disinfectant or accessory products (103) and have an opening (1) for filling, an orifice (4) in the cap (51) for restoring to atmospheric pressure, a graduated level (41) and level alert sensors.

[0131] The accessory gauges [Fig. 6] also inject pre-set doses of other accessory products independent of the function C*fn,e(X) and the channels of the programming switches (82) independently manage the compressor (23), other application systems related to the method or accessories for bathing pools

[0132] The operation of the device [Fig. 12], characterized by a fixed consumption of disinfectant with the target value being that of the synthesis parameter, guarantees the progress of the process over a period, which makes it possible to ensure that the water is held within hygienic standards by measuring directly visually by the level (41) the deviation of the ball (44) from its initial position (43) or indirectly remotely either using a video camera (16) connected or linked to the multifunction contact (9 ), placed in front of the level (41) either by alert sensors, connected, without contact with the liquid, fixed (28), (49) or mobile (43), positioned on the body (101) of the master tank and this makes it possible to anticipate the remaining product autonomy and to check with the camera video operation by the noises of the compressor (23) or other surrounding devices and in that these systems being connected or linked to the multifunction relay (9) remotely send this consumption or other information to a mobile, a tablet or a computer.

Industrial application

The application and the results of the present process relate to a test carried out from April to September with a swimming pool of 100 m3 comprising a transparent shelter which stops approximately 50% of the solar radiation and using as a disinfectant product of 1 ' sodium hypochlorite in aqueous solution.

For the application of the new process, the calibration of the dose is done by positioning the graduation of the ruler (10) on the volume of a pool of 50 m3 instead of 100 m3 since the shelter stops 50 % UV and the automatic disinfection mode chosen on the switch (82) is the Normal mode (93) whose program launches 4 injections per night at (47) [Fig. 2] and [Fig. 3], each injection being carried out in 10s, i.e. the delivery time of the dose of the static gauge, each of the doses being spaced from the other by 10 minutes.

The result of the consumption test is immediate by manually launching the test mode (95) of the switch (82) 4 times and spaced out each time by a few minutes to allow the gauge to fill with the dose defined by the position of the ruler (10),

The filtration time is 8 fixed hours per day without the need to control the temperature of the water since in the new process the only function that remains for the filtration is to set the water in motion to filter it and send directly the dose of disinfectant in the pool water.

The results of the application concern consumption, regulation of water parameters, process management and resolution of technical problems encountered.

The electrical consumption of the device [Fig. 12] is negligible for operation of the compressor (23) for 4 minutes per 24 hours, which allows it to be powered independently by solar energy.

[0139] The daytime regulation of the disinfectant content by solar radiation has been verified since with a 100 m3 pool comprising a shelter that stops 50% of solar UV, we were able to halve the normal dose used for an open-air pool while maintaining the quality of the water.

[0140] The regulation of Ph, despite the variations in its value during the 6 months, was done in a natural way without inconvenience for water retention.

[0141] The piloting of the process consisted only in monitoring the consumption visually or remotely by the video camera (16) connected by the multifunction relay (9) to a mobile, a tablet or a computer and to check once and for all over a period, if the consumption of disinfectant product complies with the value of the summary parameter. As the consumption is fixed, the monitoring of the consumption made it possible to anticipate the date of the next filling of the master tank (10) and of its slave tanks (40) by reading using the video camera of the remaining quantity of disinfectant product.

[0142] Following a malfunction resulting from a failure of the filtration detected by the auditory function the video camera (16), the transfer of the pool water could be avoided remotely by manually triggering series of n doses of disinfectant by the test disinfection mode (95) with entry of the number n.

[0143] Cleaning the dose ejection system with pressurized air prevented clogging of the ejection system [Fig. 7] by residues or by the chemical reaction of calcification in (35) between the disinfectant and the water to be treated.

[0144] In summary, this new night disinfection process with natural daytime regulation has enabled the water to adapt naturally to disturbances in the internal and external environment of the pool, despite temperature peaks in the pool. water above 32 degrees, which is beyond the limit of 28 degrees generally accepted for conventional treatments, while respecting the water quality standards generally accepted for bathing water, by freeing itself from controls physico-chemical properties of the water and by reducing the filtration time while supplying the device [Fig. 12] in autonomous energy using solar panels.

[0145] This application highlights an immediate calibration of the dose C*fn,e(X) by rule (10) which allowed a good range of process efficiency with a phenomenon of acceleration of the disinfection result thanks to the instantaneousness of micro doses with a mass effect of volume C*fn,e(X) of the order of a micro compared to the volume X of the pool measured in litres.

This new method has better performance compared to current systems.

Preferably, the invention relates to a global disinfection device: - in which, on the one hand the calibration of the daily consumption of product is done initially with as a fixed target value that of the synthesis parameter n*C*fn,e(X) and on the other hand the adjustment of the daily consumption of disinfectant product is done around the value of the synthesis parameter so as to take into account the particularities of the internal and external environment of the basin;

[0149] - in which the box (19), supplied with electricity from the mains or with independent energy, comprises an air compressor and connected and/or manual systems such as a multi-way programming switch (82), a multiway valve (81) and control elements;

[0151] - which allows on site or remotely from a mobile, a tablet or a computer to directly correct the consequences of malfunctions or disturbances due to the environment such as a transfer of the water in the pool, by manually triggering the disinfection mode (95) with entry of the number n to perform additional disinfection series of n injections each of volume C*fn,e(X);

[0152] - in which the body of the static gauge (105) is closed at its ends with the air inlet (8) at the level of the reserve (28) and the valve (30) at the level of the bottom (2 ) to optimize both the operation of the calibration and dose ejection system [Fig. 7] and the useful volume of disinfectant by reducing the volume of the reserve (3);

[0153] - in which, when the body of the static gauge (105) is fixed outside the master tank (101) it fills indirectly through the filter (53) at the outlet (70) of the master tank (101) [Fig. 9]

[0154] - in which, when the body (105) of the static gauge is inside the master tank (101) immersed in the product and when the body of the static gauge (105) is fixed outside the master tank (101), it is emptied in both cases by air pressure via the orifice (6) of the same volume C*fn,e(X) in the basin via (35);

- in which the volume between the orifice (6) and the top of the body of the gauge (105) is equal to the volume defined by the function C*fn,e(X); [0156] - allowing without physico-chemical control of the water, to ensure compliance with generally accepted quality standards for bathing water by direct reading on site of the level (41) which equips the reservoirs [Fig. 9] or indirectly remotely by systems connected or linked to the multifunction relay (9); [0157] - in which the programming switch (82) associated with the multi-way valve (81) manages the operation of the chosen static gauge [Fig. 6] and with the light sensors (59), temperature (13), levels (28) (43) (49) and the video camera (16) this allows the automatic operation of the whole process.
