Description

TECHNICAL FIELD OF THE INVENTION

[0001] The field of the invention relates to the management of water in a system comprising a basin, for example a swimming pool. STATE OF THE ART

[0002] It is first of all observed that due to the increasing number of heatwaves affecting many regions, water is becoming a precious resource that must be preserved and managed effectively in all its areas of use, particularly in the management of basins and swimming pools.

[0003] There figure 1illustrates an example of water management of a swimming pool 100. As illustrated (the dotted arrows represent the direction of movement of the water, in this figure and the following ones), the water of the swimming pool is here filtered in a filtration assembly 102 comprising in particular a pump 104 and a filter 106, for example a sand filter. For these purposes, the water is captured by a skimmer (or swimming pool water surface skimmer) 108 and / or a bottom drain 110 via a pipe 112, filtered in the filtration assembly 102 and discharged towards a discharge nozzle 114 via a pipe 116.

[0004] The pool water is thus recycled.

[0005] Furthermore, a swimming pool generally includes an overflow, often located in a skimmer, for example the overflow 118, to, if necessary, evacuate an excess volume of water, for example due to rain or excessive filling. This excess volume of water is generally evacuated into a wastewater circuit, for example into a sewer 120, via a pipe 122.

[0006] However, it has been observed that the implementation of an overflow leads to the evacuation of a quantity of water which is not in excess, but which reaches the overflow due to water movements, for example due to bathers. It is then necessary to consume water to compensate for this quantity of water evacuated.

[0007] It is noted that swimming pools are often equipped with a sand filter comprising a multi-function valve and a tank containing sand, often in several layers of different grain sizes, to filter impurities from the water. Although it is very simple to operate and maintain, such a filter has disadvantages, particularly with regard to the quantity of water discharged during cleaning of the filter. During this operation, called backwashing, the pollutant load is partially evacuated by reversing the direction of the water in the filter and the dirty water is discharged into the sewer 120 via a pipe 124.

[0008] We also know, notably in document DE2363751, water management systems which combine a swimming pool with a water storage tank to recover excess water from the swimming pool basin.

[0009] However, water management in a swimming pool is not optimal in terms of water consumption. There is therefore a need to improve water management in a swimming pool and, more generally, in a basin. STATEMENT OF THE INVENTION

[0010] The present invention relates to an improved water storage system.

[0011] The invention thus relates to a water management system for a basin, the system comprising a hydraulic assembly comprising at least one basin provided with at least one water outlet to be filtered and at least one filtered water inlet, a filtration assembly configured to filter water received directly or indirectly from said at least one water outlet and supply the filtered water to said at least one water inlet of said at least one basin, and at least one overflow for evacuating an excess volume of water from said hydraulic assembly, the system further comprising a water storage tank comprising at least one water inlet connected to said at least one overflow and comprising at least one water outlet, characterized in that said filtration assembly is further configured to filter water received directly from the at least one water outlet of said storage tank and supply the filtered water to at least one water inlet of said storage tank.

[0012] The invention makes it possible, in particular, to optimize water consumption by avoiding the discharge of excess water from a pool. It allows the use of the pool's water filtration system to filter the water from the storage tank in a closed circuit.

[0013] The water in the storage tank can thus be filtered according to the specific needs (frequency, duration, intensity, etc.) of the stored water, which may be different from the filtration needs of the pool water.

[0014] In particular, water from storage tanks may remain stored for a certain time before being used for the pond or other purposes. It is essential to ensure its conservation during this storage time.

[0015] Preferred, simple, convenient and economical features of the device according to the invention are presented below.

[0016] For example, said at least one basin comprises said at least one overflow.

[0017] According to particular embodiments, said at least one basin is an overflow basin, said hydraulic assembly further comprising a buffer tank. Said buffer tank may further comprise at least one overflow.

[0018] Still according to particular embodiments, said at least one overflow comprises a water outlet located at a predetermined water height representative of a nominal water volume of said hydraulic assembly.

[0019] Still according to particular embodiments, said buffer tank comprises at least one water height sensor configured to detect an excess volume of water from said hydraulic assembly, said buffer tank further comprising a discharge pump controlled by said at least one sensor to discharge said excess volume of water from said hydraulic assembly.

[0020] Still according to particular embodiments, said evacuation pump is a pump of said filtration assembly.

[0024] Still according to particular embodiments, at least one water inlet of said storage tank is connected directly or indirectly to a rainwater collector.

[0025] Still according to particular embodiments, said filtration assembly comprises a membrane filter. BRIEF DESCRIPTION OF THE FIGURES

[0026] Other advantages, aims and particular characteristics of the present invention will emerge from the following non-limiting description of at least one particular embodiment of the devices, system and methods which are the subject of the present invention, with reference to the appended drawings, in which: there figure 1 illustrates an example of swimming pool water management according to the prior art and the figures 2 And 3 illustrate examples of swimming pool water management with the implementation of a water storage tank; and figures 4 to 6illustrate examples of swimming pool water management, according to particular embodiments of the invention. DETAILED DESCRIPTION OF THE INVENTION

[0027] According to embodiments, the excess water volume of a pool is recovered to be stored in a storage tank whose contents are filtered with the same filter assembly as that used to filter the water of the pool. The excess water volume is a volume of water that exceeds a nominal water volume of the pool, corresponding to a desired volume, for example associated with a desired water height (in the pool or in a buffer tank, for example in the case of an infinity pool), beyond the natural (or nominal or optimal) tidal range. The excess water volume is for example due to rain. Indeed, due to its large surface area, a swimming pool plays an important role in capturing rainwater, like a building roof.The capture of this water, its storage and its filtering allow it to be preserved for later use, for example to add water to the basin when needed (particularly in the event of evaporation), watering plants, washing a vehicle, etc.

[0028] There figure 2 illustrates a first example of water management of a swimming pool 200, with the implementation of a water storage tank. As illustrated, the water of the swimming pool is filtered in a filtration assembly 202 comprising in particular a pump 204 and a filter 206, for example a membrane filter. According to this example, the water is captured by a skimmer (or swimming pool water surface skimmer) 208 and / or a bottom drain 210 via a pipe 212, filtered in the filtration assembly 202 and discharged to a discharge nozzle 214 via a pipe 216. The water of the swimming pool is thus recycled.

[0029] According to the illustrated example, the swimming pool 200 comprises an overflow 218, here located in the skimmer 208, to evacuate an excess volume of water, for example due to rain. This excess volume of water is evacuated to a storage tank 220, via a pipe 222. As illustrated, the storage tank 220 comprises a water outlet 224 making it possible to convey the water contained therein to the filtration assembly 202, via the pipe 212.

[0030] The filtration assembly 202 thus filters water from the swimming pool 200 and the storage tank 220 and returns the filtered water to the swimming pool via the pipe 216.

[0031] Naturally, the 200 pool (like the pools shown on the figures 3 to 6 ) may include several skimmers, several bottom drains, several return drains and / or several overflows.

[0032] It is observed here that valves or solenoid valves (not shown) may be used to select certain circuits. For illustration, solenoid valves may be placed upstream of the pump to select, as the source of water to be filtered, the pool 200, the storage tank 220 or the pool 200 and the storage tank 220.

[0033] There figure 3illustrates a second example of water management of a swimming pool 300, with the implementation of a water storage tank. According to this example, the swimming pool 300 is an infinity pool comprising a buffer tank 326. As illustrated, the water of the swimming pool is filtered in a filtration assembly 302 here comprising a pump 304 and a filter 306, for example a membrane filter. For these purposes, the water is captured by one or more drains 328 of the buffer tank 326 (advantageously comprising at least one bottom drain) and, preferably, by one or more bottom drains 310 of the swimming pool via a pipe 312, filtered in the filtration assembly 302 and discharged to a discharge nozzle 314 of the swimming pool 300 via a pipe 316. The water of the swimming pool is thus recycled.

[0034] When the filtration system is in operation, the water drawn into the buffer tank is forced back into the pool, causing the pool to overflow into the buffer tank, as shown with the dotted arrow.

[0035] According to the illustrated example, the buffer tank 326 comprises an overflow 318 for evacuating an excess volume of water, for example due to rain falling in the swimming pool 300. This excess volume of water is evacuated to a storage tank 320 via a pipe 322. The storage tank 320 further comprises a water outlet 324 to the filtration assembly 302, via the pipe 312.

[0036] The filtration assembly 302 thus filters water from the swimming pool 300 and / or from the buffer tank 326 and from the storage tank 320 and delivers the filtered water to the swimming pool via the pipe 316.

[0037] Again, valves or solenoid valves (not shown) may be used to select certain circuits. For illustration, solenoid valves may be placed upstream of the pump to select, as the source of water to be filtered, the pool 300, the storage tank 320 and / or the buffer tank 326. A solenoid valve (not shown) may be placed at the junction of the outlets of the pumps 310 and 328 to prevent any transfer of water to the buffer tank 326.

[0038] There figure 4 illustrates a third example of water management of a swimming pool 400, according to particular embodiments of the invention. In this example, the filtration of the swimming pool water can be separated from the filtration of the water in the storage tank, although using the same filtration assembly.

[0039] In this embodiment, it is an overflow pool 400 comprising a buffer tank 426. The overflow acts as an overflow for the pool 400.

[0040] The operation of the overflow and buffer tank 426 is similar to that described with reference to the figure 3 .

[0041] Additionally, the buffer tank 426 could include an overflow (not shown) similar to the overflow 318 of the buffer tank 326 of the embodiment of the figure 3 , to evacuate an excess volume of water, for example due to rain falling in the swimming pool 400. As in the embodiment of the figure 3 , this excess water volume can be discharged to a storage tank 420, as described below, via a pipeline (not shown).

[0042] The water of the swimming pool is here filtered in a filtration assembly 402 comprising a pump 404 and a filter 406, for example a membrane filter. For these purposes, the water is collected by one or more drains 427 of the buffer tank 426 (advantageously comprising at least one bottom drain) and, preferably, by one or more bottom drains 410 of the swimming pool via a first pipe 412, filtered in the filtration assembly 402 and discharged to a discharge nozzle 414 of the swimming pool 400 via a second pipe 416. The water of the swimming pool is thus recycled.

[0043] The filtration assembly 402 can, in addition to its mechanical filtration action, allow the chemical disinfection of the water by adding, for example, chlorine.

[0044] According to the illustrated example, the buffer tank 426 comprises a water height (or water level) sensor connected to a pump to evacuate an excess volume of water, for example due to rain falling in the swimming pool 400. This excess volume of water is evacuated to the storage tank 420. The storage tank 420 comprises a water inlet 422 to receive this excess water via a third pipe 428 and a water outlet 424 to the filtration assembly 402, via a fourth pipe 429.

[0045] The filtration assembly 402 thus filters water from the swimming pool 400 and / or from the buffer tank 426 and from the storage tank 420 and delivers the filtered water to the swimming pool via the pipe 416.

[0046] The filtration assembly 402 is also provided to filter the water from the storage tank 420 and discharge the filtered water to the storage tank 420 via the third pipe 428 connected to the water inlet 422 of the storage tank 420.

[0047] Controlled valves or solenoid valves 452, 456, 458, 459 are provided respectively on each pipe 412, 416, 428, 429 of the circuit in order to manage the circulation of water in the filtration assembly 402.

[0048] In particular, when the valves 452, 456 respectively equipping the first and second pipes 412, 416 are closed, and the valves 458, 459 respectively equipping the third and fourth pipes 428, 429 are open, the filtration assembly 402 is configured to filter in a closed circuit the water stored in the storage tank 420.

[0049] Filtration of the water in the 420 storage tank provides clean (mechanical filtration) and possibly disinfected water.

[0050] The advantage of closed-circuit filtration of the water stored in the 420 storage tank is that it is possible to adapt the filtration and / or disinfection of the water to the specific needs of the tank depending on the expected duration of water storage and / or foreseeable uses (filling the 400 swimming pool basin but also watering or cleaning).

[0051] The filtration of the water stored by the filtration assembly 402 in a closed circuit can thus be adapted in duration, frequency, intensity, etc., for example by carrying out several successive passages of the water stored in the filtration assembly 402.

[0052] In addition, the water in the storage tank 420 can remain stored for a certain time before being used to fill the pool or for other purposes. As a result, it is essential to ensure its conservation, which is the role of filtration / disinfection.

[0053] Since the 420 storage tank is not subject to the same environment as the basin, the filtration and disinfection needs are different.

[0054] Indeed, the water in the pool is exposed to light and the surrounding flora and fauna, receives people, can be contaminated by sunscreen products, etc., which encourages the development of micro-organisms and the proliferation of bacteria.

[0055] Conversely, the water in the storage tank is less exposed to light and to exchanges with the outside world, and requires less treatment to maintain good sanitary quality.

[0056] Filtration / disinfection can therefore be adapted and personalized to meet the exact needs of the water stored in the storage tank 420, for example, by avoiding the use of toxic products or by optimizing the filtration time, that is to say by consuming only the necessary electrical energy.

[0057] For example, when stored water is used for watering purposes, the chlorine level must be much lower than that of water stored to fill the pool 400.

[0058] The filtration assembly 402 is further configured to filter water received directly from the water outlet 424 of the storage tank 420 and supply the filtered water to the water inlet 414 of the basin 400. In this configuration, the valves 456, 459 respectively equipping the second and fourth pipes 416, 429 are open, and the valves 452, 458 respectively equipping the first and third pipes 412, 428 are closed.

[0059] Likewise, the filtration assembly 402 is configured to filter water received from the water outlet 410 of the basin 400 or from the water outlet 427 of the buffer tank 426 and supply the filtered water to the water inlet 422 of the storage tank 420. In this configuration, the valves 456, 459 respectively equipping the second and fourth pipes 416, 429 are closed, and the valves 452, 458 respectively equipping the first and third pipes 412, 428 are open.

[0060] The water management system as described in relation to the example of the figure 4 allows the circulation of water in the different pipes 412, 416, 428, 429 of the circuit to be adapted to manage the filtration of the water in the basin 400 and / or the storage tank 420 and its temporary storage or reuse in the basin 400, according to the specific needs of the system at a given time.

[0061] According to a particular embodiment, the water height sensor 430 as well as the controlled valves or solenoid valves 452, 456, 458, 459 are used in cooperation with the filtration assembly to capture water from the swimming pool 400 and / or the buffer tank 426 and discharge it towards the storage tank 420. According to other embodiments, a specific pump is used to evacuate an excess volume of water.

[0062] Still according to particular embodiments, the buffer tank 426 comprises two water height sensors located at different heights: a high sensor and a low sensor. According to this embodiment, the pump used to evacuate an excess volume of water (e.g., a specific pump or a pump of the filtration assembly) is triggered when the high sensor detects the presence of water. It is stopped as soon as the low sensor no longer detects the presence of water.

[0063] It is observed here that such a mechanism for evacuating an excess volume of water can also be implemented in a swimming pool which is not an infinity pool, the water height sensor(s) being placed directly in the swimming pool or elsewhere, for example in one or more skimmers, and the water being evacuated through one or more specific drains and / or through one or more drains used for filtering the water.

[0064] There Figure 5 illustrates a fourth example of water management of a swimming pool 500, according to particular embodiments of the invention. In this example, the filtration of the swimming pool water is separate from the filtration of the water in the storage tank, although using the same filtration assembly.

[0065] As illustrated, the water of the swimming pool 500 is filtered in a filtration assembly 502 comprising a pump 504 and a filter 506, for example a membrane filter. For these purposes, the water is collected by one or more skimmers 508 and / or one or more bottom drains 510 via a first pipe 512, filtered in the filtration assembly 502 and discharged to one or more discharge nozzles 514 via a second pipe 516. The water of the swimming pool is thus recycled.

[0066] The filtration assembly 502 can, in addition to its mechanical filtration action, allow the chemical disinfection of the water by adding, for example, chlorine.

[0067] As illustrated, the swimming pool 500 comprises one or more overflows 518, here located in the skimmer(s) 508, for evacuating an excess volume of water, for example due to rain. This excess volume of water is evacuated to a storage tank 520 via a third pipe 522. The storage tank 520 further comprises a water outlet 524 to the filtration assembly 502, via a fifth pipe 529. After filtration, the water from the storage tank 520 is discharged to the latter via a fourth pipe 528 and a particular inlet 530.

[0068] Alternatively, the fourth pipe 528 could be connected to the third pipe 522 to be discharged into the storage tank 520 through the same inlet as that used to discharge the excess water volume to the storage tank 520, provided that a solenoid valve is provided to separate the flows in the third and fourth pipes 522, 528.

[0069] As illustrated, the filtration system 502 here comprises two separate inlets and two separate outlets, making it possible to filter the water of the swimming pool 500 and the water of the storage tank 520 separately. The selection of the water inlet to be filtered and the outlet to which the filtered water must be discharged can be carried out using controlled valves or solenoid valves 552, 556, 558, 559 equipping the first, second, fourth and fifth pipes 512, 516, 528, 529 respectively.

[0070] Alternatively, the filtration system 502 could have only one inlet and one outlet, with the first and fifth lines 512, 529 being alternatively opened and closed by a single three-way valve (not shown) and the second and fourth lines 516, 528 being alternatively opened and closed by a single three-way valve (not shown).

[0071] It is observed here that such a mechanism allowing separate filtration of the pool water and the storage tank water can also be implemented in other types of pools or swimming pools, for example in an infinity pool.

[0072] The advantages provided by the separate filtration of the water stored in the storage tank 520 are identical to those described previously with reference to the embodiment illustrated in figure 4 .

[0073] In particular, when the valves 552, 556 respectively equipping the first and second pipes 512, 516 are closed, and the valves 558, 559 respectively equipping the fourth and fifth pipes 528, 529 are open, the filtration assembly 502 is configured to filter in a closed circuit the water stored in the storage tank 520.

[0074] The filtration assembly 502 is further configured to filter water received directly from the water outlet 524 of the storage tank 520 and supply the filtered water to the water inlet 514 of the basin 500. In this configuration, the valves 556, 559 respectively equipping the second and fifth pipes 516, 529 are open, and the valves 552, 558 respectively equipping the first and fourth pipes 512, 528 are closed.

[0075] Likewise, the filtration assembly 502 is configured to filter water received from the water outlet 510 of the basin 500 and supply the filtered water to the water inlet 530 of the storage tank 520. In this configuration, the valves 556, 559 respectively equipping the second and fifth pipes 516, 529 are closed, and the valves 552, 558 respectively equipping the first and fourth pipes 512, 528 are open.

[0076] The water management system as described in relation to the example of the Figure 5 allows the circulation of water in the different pipes 512, 516, 528, 529 of the circuit to be adapted to manage the filtration of the water in the basin 500 and / or the storage tank 520 and its temporary storage or reuse in the basin 500, according to the specific needs of the system at a given time.

[0077] There figure 6 illustrates a fifth example of water management of a swimming pool 600, according to particular embodiments of the invention. This example is similar to that illustrated in the Figure 5 , but also includes means of recovering rainwater, here roof water.

[0078] As illustrated, the water of the swimming pool 600 is filtered in a filtration assembly 602 comprising a pump 604 and a filter 606, for example a membrane filter. For these purposes, the water is collected by one or more skimmers 608 and / or one or more bottom drains 610 via a first pipe 612, filtered in the filtration assembly 602 and discharged to one or more discharge nozzles 614 via a second pipe 616. The water of the swimming pool is thus recycled.

[0079] The filtration assembly 602 can, in addition to its mechanical filtration action, allow the chemical disinfection of the water by adding, for example, chlorine.

[0080] According to the illustrated example, the swimming pool 600 comprises one or more overflows 618, here located in the skimmer(s) 608, for discharging an excess volume of water in the swimming pool, for example due to rain. This excess volume of water is discharged to a storage tank 620 via a third pipe 622. The storage tank 620 further comprises a water outlet 624 to the filtration assembly 602, via a fifth pipe 629. After filtration, the water from the storage tank 620 is discharged to the latter via a fourth pipe 628 and a particular inlet 630 (as illustrated).

[0081] Alternatively, the fourth pipe 628 could be connected to the third pipe 622 to be discharged into the storage tank 620 through the same inlet as that used to discharge the excess water volume to the storage tank 620, provided that a solenoid valve is provided to separate the flows in the third and fourth pipes 622, 628.

[0082] The filtration assembly 602 thus filters the water from the swimming pool 600 or from the storage tank 620, separately, and delivers the filtered water to the swimming pool via the second pipe 616 or to the storage tank 620 via the fourth pipe 628.

[0083] As described with reference to the Figure 5, a selection device such as controlled valves or solenoid valves 652, 656, 658, 659 may be used at the inlet and outlet of the filtration assembly 602 to recover water from the pool 600 or the storage tank 620 and to discharge the water to the pool 600 or the storage tank 620.

[0084] In particular, when the valves 652, 656 respectively equipping the first and second pipes 612, 616 are closed, and the valves 658, 659 respectively equipping the fourth and fifth pipes 628, 629 are open, the filtration assembly 602 is configured to filter in a closed circuit the water stored in the storage tank 620.

[0085] The filtration assembly 602 is further configured to filter water received directly from the water outlet 624 of the storage tank 620 and supply the filtered water to the water inlet 614 of the basin 600. In this configuration, the valves 656, 659 respectively equipping the second and fifth pipes 616, 629 are open, and the valves 652, 658 respectively equipping the first and fourth pipes 612, 628 are closed.

[0086] Likewise, the filtration assembly 602 is configured to filter water received from the water outlet 610 of the basin 500 and supply the filtered water to the water inlet 630 of the storage tank 620. In this configuration, the valves 656, 659 respectively equipping the second and fifth pipes 616, 629 are closed, and the valves 652, 658 respectively equipping the first and fourth pipes 612, 628 are open.

[0087] The water management system as described in relation to the example of the figure 6 allows the circulation of water in the different pipes 612, 616, 628, 629 of the circuit to be adapted to manage the filtration of the water in the basin 600 and / or the storage tank 620 and its temporary storage or reuse in the basin 600, according to the specific needs of the system at a given time.

[0088] According to the example illustrated on the figure 6 , the storage tank 620 further recovers rainwater from sources other than the swimming pool, in particular from roofs 640 of one or more houses. This water is here recovered via gutters 642, downspouts 644 and a sixth pipe 646. The water thus recovered can be pre-filtered in a pre-filter (not shown) before being discharged to the storage tank 620 where it is filtered by the filtration assembly 602.

[0089] Thus, the filtration assembly 602 makes it possible to filter the collected rainwater, in a closed circuit independent of the circulation circuit of the water of the swimming pool 600. Thus, the untreated rainwater is not mixed with the water of the swimming pool which has undergone chemical treatments.

[0090] Since the chemistry of swimming pool water is sensitive, it is therefore possible to independently filter and disinfect the water in the storage tank 620 (rain or other source) before reinjecting it into the pool basin 600, and therefore mixing it with clean pool water.

[0091] Furthermore, when new rainwater arrives in the storage tank 620, it is necessary to have a filtration and disinfection action greater than that necessary to maintain the quality of this water over time.

[0092] It is observed here that such a rainwater harvesting mechanism can also be implemented in other types of swimming pools, for example in an infinity pool. Similarly, the water collected and directed to the storage tank can come from sources other than those mentioned above, for example from a stream, a well, a wastewater treatment system, etc.

[0093] It is further observed that if the examples illustrated on the figures 2 to 6 represent only one storage tank, several storage tanks can be used. They can be connected in series and / or in parallel. Still according to embodiments, the storage tank(s) comprise one or more overflows.

[0094] It is further observed that if the water contained in the storage tank(s) can be used to supply the swimming pool, for example to top up the level, it can be used for other purposes, for example for watering, washing, etc., in particular when it is not mixed with the swimming pool water, for example in the case of separate filtration as illustrated in the embodiments of the figures 4 and figures 5 And 6 .

[0095] Although not illustrated in the figures, the filtration assembly used to filter the water of the swimming pool or pond and the water of the storage tank(s) comprising a pump and at least one filter, for example a membrane filter, may also comprise other elements such as elements for controlling and / or adjusting the chemistry of the water, and for example, as indicated above, allowing the chemical disinfection of the water by the addition of chlorine.

[0096] Finally, it is noted that a membrane filter allows for a constant quality of the filtered liquid regardless of the incoming pollutant load. For example, the membrane can be a multi-channel inorganic microfiltration membrane. The filter can thus use multi-layer membranes of recrystallized silicon carbide (R-SiC) carried by a unique honeycomb monolith geometry. This is, for example, the Crystar filter from the Saint-Gobain company (Crystar and Saint-Gobain are trademarks).
