[0010] This embodiment will be described below with reference to the drawings. <Water Production System S> Fig. 1 is a diagram showing an example of the overall configuration of a water production system S according to one embodiment of the present invention. The water production system S is a system that can produce water of a predetermined purpose (hereinafter referred to as "destination water") from raw water. "Raw water" refers to H ２ There are no particular limitations on the liquid as long as it contains O. For example, it may be tap water, well water, water generated from water vapor in the air, river water, seawater, wastewater (circulated water) discharged when producing drinking water, or the like.

[0011] "Purpose water" may be water produced for some purpose. For example, it may be drinking water intended for human consumption, cooking water intended for use in cooking (e.g., cooking, tea, coffee, etc.), water intended for use in showers, etc. It may also be water intended for use in laundry, circulating water (e.g., for baths, showers, etc.), water intended for medical use (e.g., saline solution, etc.), etc.

[0012] The water production system S is configured to include a water production device 1 that produces destination water from raw water and a user terminal 2 of a user who wishes to produce the desired destination water, which are connected via a network N. The network N is, for example, the Internet, a LAN (Local Area Network), a VPN (Virtual Private Network), etc.

[0013] [Water production apparatus 1] The water production apparatus 1 generates information (hereinafter referred to as "water adjustment information") for adjusting raw water to produce destination water based on information regarding the specifications of the destination water (hereinafter referred to as "water specification information"). The water production apparatus 1 produces destination water based on the generated water adjustment information. The amount of destination water produced by the water production apparatus 1 is not important. For this reason, the water production apparatus 1 can be installed in homes, privately run restaurants, etc., or in large-scale plants such as factories.

[0014] The water production apparatus 1 has components that perform various processes and adjustments on water (for example, the water measurement unit 22 and water production unit 23 shown in FIG. 2), and an information processing component that determines the details of the processes and adjustments performed by these components and executes information processing to control these components (for example, an information processing device consisting of the CPU 11 to removable media 21 shown in FIG. 2). The water production apparatus 1 can execute a predetermined application program that makes the above-mentioned water production system S available. In addition to having the function of producing target water from raw water, the water production apparatus 1 can also transmit various types of information to the user terminal 2 and to the outside. The water production apparatus 1 can also acquire various types of information transmitted from the user terminal 2 and to the outside and perform various types of processing.

[0015] For example, the water producing apparatus 1 acquires water specification information transmitted from the user terminal 2 and generates water adjustment information based on the water specification information. The water producing apparatus 1 then produces destination water from raw water based on the generated water adjustment information. This allows the user to produce and use the destination water they desire.

[0016] Hereinafter, the series of processes by which the water producing apparatus 1 produces destination water based on the water adjustment information will be referred to as the "water production process." In the water production process, various adjustment processes are carried out on the raw water in stages, and the destination water is ultimately produced. For this reason, the properties of the "raw water" gradually change as the various adjustment processes are carried out in stages. However, in the description of this embodiment, the water will be referred to as "raw water" at any stage until all of the various adjustment processes are completed and the "destination water" is produced.

[0017] The water adjustment information generated by the water producing apparatus 1 includes information regarding the adjustment of substances (hereinafter referred to as "additives") that change the components of raw water when added to the raw water. Examples of additives that can be added to raw water include mineral components such as calcium, magnesium, sodium, potassium, zinc, iron, and manganese, as well as vitamin components. The information regarding the adjustment of additives includes information regarding the addition of a substance to the raw water to add a new component to the raw water or the addition of a component to increase the content of the component in the raw water (additive adjustment). The information regarding the adjustment of additives also includes information regarding the addition of a substance to the raw water to reduce or remove the content of a component in the raw water (subtractive adjustment). Specific examples of water adjustment information that include information regarding the adjustment of additives will be described later.

[0018] The water production apparatus 1 performs pretreatment based on the generated water adjustment information as one of the processes included in the water production process. "Pretreatment" refers to a process of removing certain components contained in the raw water (e.g., mineral components and residual chlorine) and a process of neutralizing the pH (hydrogen ion concentration) of the raw water. As pretreatment, the water production apparatus 1 removes mineral components by passing the raw water through a filter (hereinafter referred to as an "RO filter") made of a reverse osmosis membrane (RO membrane). Pretreatment is performed depending on the state of the raw water, and there are cases where pretreatment is not performed. Specific examples of pretreatment will be described later.

[0019] As one process included in the water production process, the water production apparatus 1 adjusts the additives to be added to the raw water based on the generated water adjustment information. Hereinafter, the process of adjusting the additives to be added to the raw water performed by the water production apparatus 1 will be referred to as the "additive adjustment process." Since the additive adjustment process is performed based on the water specification information of the target water and the measurement results of the properties of the raw water, the additive adjustment process may not be performed depending on the state of the raw water. Specific examples of the additive adjustment process will be described later.

[0020] As one process included in the water production process, the water production apparatus 1 adds additives adjusted by an additive adjustment process to raw water that has undergone pretreatment. For example, the water production apparatus 1 adds the additives by using a method such as dripping a concentrate of the additive using a pump or the like. Hereinafter, the process of adding adjusted additives to raw water performed in the water production apparatus 1 will be referred to as the "addition process." The addition process is a process that is performed after the additive adjustment process. Specific examples of the addition process will be described later.

[0021] As one process included in the water production process, the water production apparatus 1 adjusts the pH of raw water that has undergone an additive process based on the generated water adjustment information. For example, the water production apparatus 1 adjusts the pH of the raw water using a method such as electrolyzing the raw water in an electrolytic cell, diffusing ions attached to electrodes immersed in the raw water, or adding acidic water with a low pH to the raw water. Hereinafter, the process of adjusting the pH of raw water that has undergone an additive process, which is performed in the water production apparatus 1, will be referred to as the "pH adjustment process." Note that the pH adjustment process is performed depending on the state of the raw water, and there are cases where the pH adjustment process is not performed. Specific examples of the pH adjustment process will be described later.

[0022] The water production apparatus 1 adjusts the temperature of the raw water based on the generated water adjustment information as one process included in the water production process. For example, the water production apparatus 1 adjusts the temperature of the raw water based on the calculation results of the amount of power consumed during heat exchange by a compressor or the like and the heat exchange efficiency. Hereinafter, the process of adjusting the temperature of the raw water performed in the water production apparatus 1 will be referred to as the "temperature adjustment process." Note that the temperature adjustment process is a process that is performed depending on the state of the raw water, and there are cases where the temperature adjustment process is not performed. Specific examples of the temperature adjustment process will be described later.

[0023] As one process included in the water production process, the water production apparatus 1 adjusts the carbon dioxide to be injected into the raw water based on the generated water adjustment information. For example, the water production apparatus 1 adjusts the carbon dioxide to be injected into the raw water based on the time for injecting carbon dioxide gas into the raw water and the mineral ion concentration of the raw water. Hereinafter, the process performed in the water production apparatus 1 to adjust the carbon dioxide to be injected into the raw water will be referred to as the "carbon dioxide adjustment process." Note that the carbon dioxide adjustment process is a process performed depending on the state of the raw water, and there are cases where the carbon dioxide adjustment process is not performed. Specific examples of the carbon dioxide adjustment process will be described later.

[0024] The water production apparatus 1 measures the properties of the raw water at each stage of the water production process and updates the water adjustment information as needed based on the measurement results. Specifically, after each of the various adjustment processes is performed, the water production apparatus 1 measures the raw water for pH, impurities, flow rate, pressure, residual chlorine, temperature, and other factors, and updates the water adjustment information as needed based on the measurement results. The water production apparatus 1 also updates the water adjustment information as needed based on predicted values ​​calculated from actual values ​​of the measurement results of the properties of the raw water at each stage of the water production process.

[0025] More specifically, the water production apparatus 1 updates the water adjustment information using the following method. That is, the water production apparatus 1 updates the water adjustment information based on the results of a prediction of the impact on various adjustment processes after the additive treatment. The water production apparatus 1 also updates the water adjustment information based on the results of a prediction of the impact on various adjustment processes after the pH adjustment treatment. The water production apparatus 1 also updates the water adjustment information based on the results of a prediction of the impact on various adjustment processes after the temperature adjustment treatment. The water production apparatus 1 also updates the water adjustment information based on the results of a prediction of the impact on the outflow of target water after the carbonation adjustment treatment. This allows the content of various adjustment processes that affect the properties of the raw water during the water production process to be optimized. For example, it is possible to adjust the pH after additive adjustment, adjust the additive after pH adjustment, or perform both simultaneously. The configuration and processing of the water production apparatus 1 will be described in detail below.

[0026] [User Terminal 2] The user terminal 2 is an information processing device such as a smartphone, tablet terminal, or personal computer operated by a user who produces target water using the water production apparatus 1. The user terminal 2 is capable of executing a predetermined application program that enables use of the water production system S. The user terminal 2 is capable of performing various processes based on various information transmitted from the water production apparatus 1 and from the outside, as well as various information input by the user. For example, the user terminal 2 is capable of displaying water adjustment information transmitted from the water production apparatus 1 on a display or the like.

[0027] The user terminal 2 is also capable of transmitting various types of information to both the water producing apparatus 1 and the outside. For example, when an operation to input water specification information is performed, the user terminal 2 transmits the input water specification information to the water producing apparatus 1. Details of the configuration and processing of the user terminal 2 will be described later.

[0028] The above-described processing by each of the water production device 1 and the user terminal 2 that constitute the water production system S is one example. In addition, since the water production system S as a whole is required to have the functions to realize the above-described processing, some or all of the functions to realize the above-described processing may be shared or cooperated within the water production system S.

[0029] For example, some or all of the functions of the water production apparatus 1 may be functions of another information processing device in the water production system S. Also, some or all of the functions of another information processing device in the water production system S may be functions of the water production apparatus 1. Furthermore, some or all of the functions of the water production apparatus 1 may be transferred to a server or the like (not shown). This promotes processing of the water production system S as a whole and also makes it possible for processes to complement each other.

[0030] <Hardware Configuration> [Hardware Configuration of Water Production Apparatus 1] Figure 2 is a block diagram showing an example of the hardware configuration of the water production apparatus 1 that constitutes the water production system S of Figure 1. The water production apparatus 1 comprises a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an output unit 16, an input unit 17, a storage unit 18, a communication unit 19, a drive 20, a water measurement unit 22, and a water production unit 23.

[0031] The CPU 11 executes various processes in accordance with programs recorded in the ROM 12 or programs loaded from the storage unit 18 into the RAM 13. The RAM 13 also stores data and the like required for the CPU 11 to execute various processes. The CPU 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14.

[0032] The input / output interface 15 is connected to an output unit 16, an input unit 17, a memory unit 18, a communication unit 19, a drive 20, a water measurement unit 22, and a water production unit 23. The output unit 16 is composed of a display, a speaker, etc., and outputs various information as images, sounds, etc. The input unit 17 is composed of a keyboard, a mouse, a touch panel, etc., and accepts input of various information. The memory unit 18 is composed of a hard disk, a DRAM (Dynamic Random Access Memory), etc., and stores various data. The communication unit 19 communicates with other devices via the above-mentioned network N, which is composed of the Internet, etc.

[0033] Removable media 21, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, is appropriately loaded into the drive 20. Programs read from the removable media 21 by the drive 20 are installed in the storage unit 18 as needed. The removable media 21 can also store various data stored in the storage unit 18 in the same way as the storage unit 18.

[0034] The water measurement unit 22 is composed of various sensors (for example, a water quality sensor, a flow rate sensor, a weight sensor, a temperature sensor, a pressure sensor, etc.), and measures the properties of the raw water and the properties of the target water produced by the water production unit 23. From the measurement results of the properties of the raw water and the target water measured by the water measurement unit 22, the components contained in the raw water and the target water, pH value, temperature, etc. are identified.

[0035] The water production unit 23 performs water production processing. Specifically, the water production unit 23 produces destination water by performing various processes and adjustments on raw water that enters the water production device 1. The water production unit 23 outputs the produced destination water to the outside of the water production device 1. The water production unit 23 includes pipes for circulating the raw water and destination water, pumps and solenoid valves for controlling the flow rates of the raw water and destination water, tanks for storing the raw water and destination water, an electrolytic cell for electrolyzing the raw water, etc.

[0036] The water production unit 23 also includes various devices that perform various processes and adjustments to produce target water from raw water. Specifically, the water production unit 23 includes various devices that perform the pretreatment, additive adjustment process, addition process, pH adjustment process, temperature adjustment process, and carbon dioxide adjustment process described above.

[0037] [Hardware configuration of user terminal 2] The user terminal 2 has the same hardware configuration as the water production apparatus 1 shown in Fig. 2. That is, the user terminal 2 has a CPU, ROM, RAM, bus, input / output interface, output unit, input unit, memory unit, communication unit, drive, and removable media, which correspond to the CPU 11, ROM 12, RAM 13, bus 14, input / output interface 15, output unit 16, input unit 17, memory unit 18, communication unit 19, drive 20, and removable media 21, respectively, of Fig. 2.

[0038] <Functional Configuration> Figure 3 is a functional block diagram showing an example of the functional configuration of the water production apparatus 1 that constitutes the water production system S of Figure 1. [Functional Configuration of Water Production Apparatus 1] During operation, the CPU 11 of the water production apparatus 1 functions as a water specification information acquisition unit 31 as water specification information acquisition means, a management unit 32 that manages various information, a water adjustment information generation unit 33 as water adjustment information generation means, and a pre-processing unit 34 as pre-processing means. The CPU 11 also functions as an additive adjustment unit 35 as additive adjustment means, an addition unit 36 ​​as addition means, a water adjustment unit 37 as pH adjustment means, temperature adjustment means, and carbonation adjustment means, and a transmission control unit 38 that controls the transmission of various information.

[0039] Various databases are also provided in the storage unit 18 of the water producing apparatus 1. For example, a water specification DB 41 that stores water specification information and a water adjustment DB 42 that stores water adjustment information are provided.

[0040] The water specification information acquisition unit 31 acquires water specification information. For example, the water specification information acquisition unit 31 acquires water specification information transmitted from the user terminal 2 in response to a user operation via the network N. The management unit 32 stores and manages various types of information in various databases in the storage unit 18. For example, the management unit 32 stores and manages the water specification information in the water specification DB 41. Furthermore, for example, the management unit 32 stores and manages the water adjustment information in the water adjustment DB 42.

[0041] The water adjustment information generation unit 33 generates water adjustment information based on the water specification information managed by the management unit 32. The water adjustment information generation unit 33 also updates the water adjustment information based on the measurement results of the raw water at each stage where various adjustment processes are performed. Specific examples of the method by which the water adjustment information generation unit 33 updates the water adjustment information will be described later.

[0042] The pretreatment unit 34 causes the water production unit 23 (see FIG. 2) to perform pretreatment based on the water adjustment information managed by the management unit 32. The additive adjustment unit 35 causes the water production unit 23 to perform additive adjustment processing based on the water adjustment information managed by the management unit 32.

[0043] The addition unit 36 ​​causes the water production unit 23 to perform an addition process in which the additives adjusted by the additive adjustment unit 35 are added to the raw water. For example, if the addition process is a process of adding mineral components, the addition unit 36 ​​adds the mineral components by, for example, the following method. That is, the addition unit 36 ​​adds the mineral components by a method using a mineral agent cartridge that dissolves mineral components such as sodium, calcium, magnesium, and potassium and adds them to the raw water. The addition unit 36 ​​also adds the mineral components by a method using a mineral additive (e.g., a mineral addition tube in tablet form, granule form, or mesh fabric), a method using a mineral additive, or the like. The addition unit 36 ​​also adds the mineral components by a method using a composition that reacts with a predetermined mineral component.

[0044] The water adjustment unit 37 causes the water production unit 23 (see FIG. 2) to perform various adjustment processes based on the water adjustment information managed by the management unit 32. The water adjustment information managed by the management unit 32 is updated as needed by the addition process by the addition unit 36 ​​and the various adjustment processes by the water adjustment unit 37. Therefore, the water adjustment unit 37 causes the various adjustment processes to be performed based on the water adjustment information that is updated as needed.

[0045] The transmission control unit 38 controls the transmission of various types of information via the communication unit 19. Specifically, the transmission control unit 38 controls the transmission of various types of information to the user terminal 2 and to the outside. For example, the transmission control unit 38 controls the transmission of the water adjustment information generated by the water adjustment information generation unit 33 to the user terminal 2.

[0046] <Process Flow of Water Production Apparatus 1> Figure 4 is a flowchart showing an example of the overall process flow of the water production apparatus 1. Figure 5 is a flowchart showing an example of the flow of the water production process from the process in Figure 4. As shown in Figure 4, the water production apparatus 1 receives raw water (step S1). The water production apparatus 1 measures the properties of the raw water based on a user operation (step S2) and obtains the measurement results (step S3).

[0047] When the water specification information is sent from the user terminal 2 (YES in step S4), the water production apparatus 1 acquires the water specification information (step S5) and stores and manages it in a database (water specification DB 41 in FIG. 3) (step S6). On the other hand, if the water specification information has not been sent (NO in step S4), the water production apparatus 1 repeats the determination process of step S4.

[0048] The water production apparatus 1 generates water adjustment information based on the raw water property measurement results and the water specification information (step S7), and performs a water production process to produce destination water (step S8). The water production apparatus 1 then discharges the destination water produced in the water production process (step S9). This causes the water production apparatus 1 to end the process (END). Details of the water production process performed by the water production apparatus 1 will be described later with reference to FIG. 5.

[0049] 5, when the water production apparatus 1 determines that pre-processing is necessary based on the water adjustment information generated in step S7 of Fig. 4 (YES in step S801), it performs the pre-processing (step S802) and proceeds to the determination process of step S803. On the other hand, when it determines that pre-processing is not necessary (NO in step S801), the water production apparatus 1 proceeds to the determination process of step S803 without performing pre-processing.

[0050] 4, based on the water adjustment information generated in step S7, the water production apparatus 1 performs the additive adjustment process (step S804) and the addition process (step S805). The water production apparatus 1 then proceeds to the judgment process of step S806. On the other hand, if it determines that the additive adjustment process is not required (step S803, NO), the water production apparatus 1 proceeds to the judgment process of step S806 without performing the additive adjustment process.

[0051] 4, the water production apparatus 1 performs the pH adjustment process (step S807) and proceeds to the judgment process of step S808. On the other hand, if it determines that the pH adjustment process is not necessary (step S806, NO), the water production apparatus 1 proceeds to the judgment process of step S808 without performing the pH adjustment process.

[0052] 4, the water production apparatus 1 performs the temperature adjustment process (step S809) and proceeds to the judgment process of step S810. On the other hand, if it determines that the temperature adjustment process is not necessary (step S808, NO), the water production apparatus 1 proceeds to the judgment process of step S810 without performing the temperature adjustment process.

[0053] If the water production apparatus 1 determines that carbonation adjustment processing is necessary based on the water adjustment information generated in step S7 of Fig. 4 described above (YES in step S810), it performs the carbonation adjustment processing (step S811) and ends the water production processing (END). This causes the water production apparatus 1 to proceed to the processing of step S9 of Fig. 4 described above. On the other hand, if it determines that carbonation adjustment processing is not necessary (NO in step S810), the water production apparatus 1 ends the water production processing without performing the carbonation adjustment processing (END). This causes the water production apparatus 1 to proceed to the processing of step S9 of Fig. 4 described above.

[0054] 6 is a diagram showing an example of the water production device 1. As described above, the water production device 1 includes a water production unit 23. When raw water enters the device, the water production unit 23 performs pretreatment, addition treatment, pH adjustment treatment, temperature adjustment treatment, and carbon dioxide adjustment treatment on the raw water, and outputs the water to the outside of the device as target water.

[0055] As shown in FIG. 6, when raw water enters the water producing device 1, pretreatment is carried out in the water producing section 23.

[0056] A portion of the raw water that passes through the RO filter 231 as pretreatment is discharged outside the device as RO wastewater, and the remainder is treated as purified RO water for the next additive treatment. That is, when the raw water passes through the RO filter 231, it is separated into purified RO water purified by the RO filter 231 and RO wastewater containing bacteria, viruses, harmful chemicals, etc. The RO wastewater is discharged without being treated as the next additive treatment.

[0057] Furthermore, when the raw water discharged from the RO filter 231 as RO purified water is subjected to an additive process (a process of dripping mineral stock solution in the example of FIG. 6 ), the raw water that has undergone the additive process is then subjected to a pH adjustment process. Furthermore, a portion of the raw water that has undergone the pH adjustment process is discharged outside the device, and the remainder is then subjected to a temperature adjustment process. In the following example, the pH adjustment process is described as adjusting the water to alkaline, using an electrolysis adjustment method to convert the raw water into alkaline water and acidic water. Therefore, of the raw water that has undergone the pH adjustment process, the water that is discharged outside the device is sometimes referred to as "acidic water," and the water that is subjected to the temperature adjustment process is sometimes referred to as "alkaline water."

[0058] Furthermore, once the temperature of the alkaline raw water has been adjusted, the temperature-adjusted raw water is then subjected to a subsequent carbonation adjustment process, and the carbonation-adjusted raw water is then discharged outside the device as the target water produced by the water production process.

[0059] 7A to 7C are diagrams showing specific examples of water specification information, raw water measurement results before the water production process, and predicted values ​​of raw water measurement results at an intermediate stage of the water production process and predicted values ​​of destination water measurement results after the water production process. Specifically, FIG. 7A shows a specific example of water specification information. FIG. 7B shows a specific example of raw water measurement results before the water production process. FIG. 7C shows specific examples of predicted values ​​of raw water measurement results at an intermediate stage of the water production process and predicted values ​​of destination water measurement results after the water production process. The water specification information shown in FIG. 7A includes items indicating the properties of the destination water (hereinafter referred to as "adjustment items"), their input values, and units. The input values ​​of the adjustment items are, for example, values ​​input by operating the user terminal 2. Specifically, the water specification information includes adjustment items such as Temp (temperature), pH (hydrogen ion concentration), Na (sodium), K (potassium), Mg (magnesium), Ca (calcium), carbonation strength, and volume, as well as input values ​​and units for each adjustment item. Here, carbonation strength is an index representing the strength of carbonation. That is, for example, a scale from 0 to 5 can be used as an index representing the strength of carbonation. Specifically, for example, carbonation strength can be expressed in stages, with no carbonation (no added) being 0 and strong carbonation being 5. Note that in addition to the above-mentioned index, any numerical value may be used for carbonation strength. Specifically, for example, the ratio between the volume of the liquid (water) and the volume of dissolved carbon dioxide at standard conditions may be used.

[0060] 7A, the input value for Temp (temperature) is "8" (°C), the input value for pH (hydrogen ion concentration) is "9.0", the input value for Na (sodium) is "40" (mg / L), and the input value for K (potassium) is "30" (mg / L).

[0061] The raw water property measurement results shown in FIG. 7B also include measurements and units corresponding to the adjustment items in FIG. 7A. Specifically, as shown in FIG. 7B, the measured value for Temp (temperature) is "18" (°C), the measured value for pH (hydrogen ion concentration) is "8.0", and the measured value for Na (sodium) is "10" (mg / L). The measured values ​​for K (potassium) are "4" (mg / L), Mg (magnesium) are "10" (mg / L), and Ca (calcium) are "15" (mg / L). The carbonation strength is "-", and the measured value for volume is "15" (L). The raw water property measurement results shown in FIG. 7B also include "TDS" (Total Dissolved Solids) as an adjustment item that is not included in the adjustment items in FIG. 7A. As shown in FIG. 7B, the measured value for TDS (Total Dissolved Solids) is "90" (mg / L). The lower the "TDS" (total dissolved solids) measurement, the fewer impurities there are.

[0062] 7C also includes predicted values ​​for each adjustment item at each timing after pretreatment, addition treatment, pH adjustment treatment, temperature adjustment treatment, carbon dioxide adjustment treatment, and when the target water is released. Note that the addition treatment shown in FIG. 7C is a treatment for adding mineral components.

[0063] Specifically, it is predicted that after pretreatment, the Temp (temperature) will be 18°C, the pH (hydrogen ion concentration) will be 7.0, Na (sodium) will be 1 mg / L, and K (potassium) will be 0 mg / L. It is also predicted that the Mg (magnesium) will be 0 mg / L, Ca (calcium) will be 0 mg / L, the carbonation strength will be negative, the volume will be 5 L, and the TDS (total dissolved solids) will be 5 mg / L.

[0064] It is also predicted that after the addition process, the Temp (temperature) will be 18°C, the pH (hydrogen ion concentration) will be 7.0, Na (sodium) will be 40 mg / L, and K (potassium) will be 30 mg / L. It is also predicted that the Mg (magnesium) will be 40 mg / L, Ca (calcium) will be 30 mg / L, the carbonation strength will be negative, the volume will be 5.7 L, and the TDS (total dissolved solids) will be 220 mg / L.

[0065] After the pH adjustment process, the temperature is predicted to be 18°C, the hydrogen ion concentration (pH) to be 10.0, the sodium (Na) to be 40 mg / L, and the potassium (K) to be 30 mg / L. The magnesium (Mg) to be 30 mg / L, the calcium (Ca) to be 20 mg / L, the carbonation level to be negative, the volume to be 5 L, and the total dissolved solids (TDS) to be 170 mg / L.

[0066] It is also predicted that after the temperature adjustment process, the Temp (temperature) will be "4" (°C), the pH (hydrogen ion concentration) will be "10.0", Na (sodium) will be "40" (mg / L), and K (potassium) will be "30" (mg / L). It is also predicted that the Mg (magnesium) will be "30" (mg / L), Ca (calcium) will be "20" (mg / L), the carbonation strength will be "-", the volume will be "5" (L), and the TDS (total dissolved solids) will be "170" (mg / L).

[0067] After the carbonation adjustment process, the temperature is predicted to be 7°C, the pH (hydrogen ion concentration) to be 9.0, the Na (sodium) to be 40 mg / L, and the K (potassium) to be 30 mg / L. The magnesium (Mg) is predicted to be 30 mg / L, the calcium (Ca) to be 20 mg / L, the carbonation strength to be 3, the volume to be 5 L, and the TDS (total dissolved solids) to be 170 mg / L.

[0068] The target water is predicted to have a temperature of 8°C, a pH of 9.0, a sodium content of 40 mg / L, and a potassium content of 30 mg / L. The target water is also predicted to have a magnesium content of 30 mg / L, a calcium content of 20 mg / L, a carbonation strength of 2, a volume of 5 L, and a total dissolved solids content of 170 mg / L. In other words, the target water is predicted to have the same contents as the input values ​​of the water specification information.

[0069] Specific Examples of Water Adjustment Information FIGS. 8 to 12 show specific examples of water adjustment information. FIGS. 8A to 8C show specific examples of water adjustment information used in pretreatment. The water adjustment information shown in FIG. 8A includes pre-adjustment values ​​and target values ​​(hereinafter referred to as "adjustment targets") for each adjustment item subject to pretreatment. As described above, the water production apparatus 1 measures the properties of the raw water at each stage of the water production process and updates the water adjustment information as needed based on the measurement results. The water adjustment information can also include the pre-adjustment values ​​for each adjustment item of the raw water before pretreatment in the water production process. Furthermore, the adjustment targets for Na (sodium), K (potassium), Mg (magnesium), and Ca (calcium) are all "0." In other words, the mineral components Na (sodium), K (potassium), Mg (magnesium), and Ca (calcium) are removed.

[0070] The water adjustment information shown in Figure 8B includes information on the type of filters to be passed through and the order in which they are passed, as control information for causing the water production unit 23 (see Figure 2) to perform pretreatment. In the figure, PP stands for polypropylene resin, Carbon stands for a filter made from activated carbon, and UF, RO, and DI are general names for filters. Based on the water specification information managed by the management unit 32, the water production device 1 can determine whether or not to use filters (filter types) and the order in which the filters will be used, and include this information in the water adjustment information when generating the water.

[0071] The water adjustment information shown in Figure 8C also includes the filter wear level, filter loop count, water flow rate, booster pump output, and controlled water pressure as control information for pre-processing by the water production unit 23 (see Figure 2). Specifically, for example, for filter item PP, the filter wear level is "0.90" and the filter loop count is "1." It also shows that the water flow rate is "2400" (mL / min), there is no booster pump, and the controlled water pressure is "30" (PS).

[0072] That is, the water adjustment information shown in Fig. 8C includes information on how to use the types of filters that the water is passed through, as control information for causing the water production unit 23 (see Fig. 2) to perform pre-processing. The water production apparatus 1 can determine how to use each filter item (type of filter) based on the water specification information managed by the management unit 32 and the information on the types of filters that the water is passed through and the order in which they are passed, and generate the water adjustment information by including this information.

[0073] 9A to 9C show specific examples of water adjustment information used in the addition process. The addition process shown in FIG. 9A is a process for adding mineral components Na (sodium), K (potassium), Mg (magnesium), and Ca (calcium) to raw water (RO water). The water adjustment information shown in FIG. 9A includes adjustment targets for each adjustment item to be added. Specifically, the adjustment target for Na (sodium) is "40" (mg / L), and the adjustment targets for K (potassium) and Mg (magnesium) are both "30" (mg / L). The adjustment target for Ca (calcium) is also shown to be "20" (mg / L). As described above, the water production apparatus 1 measures the properties of the raw water at each stage of the water production process and updates the water adjustment information as needed based on the measurement results. However, the water adjustment information may also include the pre-adjustment values ​​for each adjustment item of the raw water before the addition process.

[0074] 9B also includes information about the adjustment amounts of mineral components to be added in the addition process, such as the mineral component content before the addition process, the amount of mineral component to be added (mg / L), the effects of various adjustment processes after the addition process, the adjustment concentration (mg / L), the total volume (L) of the target water to be produced, and the amount of mineral component to be added (mg).

[0075] 9B shows that the mineral content before the addition process is "1" (mg / L) for Na (sodium), "0" (mg / L) for K (potassium), Mg (magnesium), and Ca (calcium). It also shows that the amounts (mg / L) of mineral components that need to be added are "39" (mg / L) for Na (sodium), "30" (mg / L) for K (potassium) and Mg (magnesium), and "20" (mg / L) for Ca (calcium).

[0076] The impact of various adjustment processes after the addition process is shown to be "0" (mg / L) for Na (sodium) and K (potassium), and "10" (mg / L) for Mg (magnesium) and Ca (calcium). The adjustment concentrations (mg / L) are shown to be "39" (mg / L) for Na (sodium) and "30" (mg / L) for K (potassium). The adjustment concentrations are also shown to be "40" (mg / L) for Mg (magnesium) and "30" (mg / L) for Ca (calcium). The total volume (L) of the target water is also shown to be "5" (L). The amounts of mineral components added are shown to be "195" (mg) for Na (sodium), "150" (mg) for K (potassium), "200" (mg) for Mg (magnesium), and "150" (mg) for Ca (calcium).

[0077] 9C includes the concentration of the mineral stock solution, the required drip amount, the pump flow rate, and the number of seconds the pump will operate, as control information for causing the water production unit 23 (see FIG. 6) to perform the addition process. Specifically, the example in FIG. 9C shows that the concentrations of the mineral stock solution are "500" (mg / L) for both Na (sodium) and K (potassium), and "1500" (mg / L) for both Mg (magnesium) and Ca (calcium).

[0078] The required drip volumes are also shown to be "390" (mL) for Na (sodium), "300" (mL) for K (potassium), "133" (mL) for Mg (magnesium), and "100" (mL) for Ca (calcium). The pump flow rate is also shown to be "4" (mL / sec). The pump operation times are also shown to be "97.5" (seconds) for Na (sodium), "75" (seconds) for K (potassium), "33" (seconds) for Mg (magnesium), and "25" (seconds) for Ca (calcium).

[0079] 10A to 10C show specific examples of water adjustment information used in the pH adjustment process. The water adjustment information shown in FIG. 10A indicates that the adjustment target for pH (hydrogen ion concentration), which is the adjustment item subject to the pH adjustment process, is "9." In other words, the pH adjustment process involves adjustment to bring the pH (hydrogen ion concentration) to "9." As described above, the water production device 1 measures the properties of the raw water at each stage of the water production process and updates the water adjustment information as needed based on the measurement results. However, the water adjustment information can also include the pH value of the raw water itself before the pH adjustment process.

[0080] The water adjustment information shown in FIG. 10B also includes information regarding the amount of pH (hydrogen ion concentration) adjustment. That is, the information includes the pH (hydrogen ion concentration) before the pH adjustment process, the effects of various adjustment processes after the pH adjustment process, and the adjusted pH. Specifically, the example in FIG. 10B shows that the pH (hydrogen ion concentration) before the pH adjustment process is "7," the effects of various adjustment processes after the pH adjustment process are "1," and the adjusted pH is "10." The effects of various adjustment processes after the pH adjustment process may be calculated, for example, by acquiring real-time measurements of the properties of the raw water before and after the pH adjustment process, or may be calibrated based on a previously measured, accurate pH.

[0081] 10C also includes TDS (total dissolved solids), voltage, current control, and power consumption as control information for causing the water production unit 23 to perform a pH adjustment process. Specifically, the example in FIG. 10C shows that the TDS (total dissolved solids) is "220" (mg / L), the voltage is "24" (V), the current control is "2" (Amax), and the power consumption is "35" (W). The control information for voltage, current control, and power consumption is calculated as information for electrolyzing raw water in the electrolytic cell, and is calculated based on, for example, the influence of the concentration of additives (mineral components), etc.

[0082] 11A to 11C show specific examples of water adjustment information used in the temperature adjustment process. The water adjustment information shown in FIG. 11A indicates that the adjustment target for Temp (temperature), which is an adjustment item subject to the temperature adjustment process, is "8" (°C). In other words, the temperature adjustment process involves adjustment to set Temp (temperature) to "8" (°C). As described above, the water production device 1 measures the properties of the raw water at each stage of the water production process and updates the water adjustment information as needed based on the measurement results, but the water adjustment information can also include the temperature value of the raw water itself before the temperature adjustment process.

[0083] The water adjustment information shown in FIG. 11B also includes information regarding the amount of Temp (temperature) adjustment. That is, it includes the Temp (temperature) before the temperature adjustment process, the temperature difference that requires adjustment, the impact (heat loss) of various adjustment processes after the temperature adjustment process, the adjustment temperature, and the adjustment value. Specifically, the example in FIG. 11B shows that the Temp (temperature) before the temperature adjustment process is "18" (°C), the temperature difference that requires adjustment is "-10" (°C), and the impact (heat loss) of various adjustment processes after the temperature adjustment process is "4" (°C). It also shows that the adjustment temperature is "4" (°C) and the adjustment value is "-14" (°C).

[0084] 11C includes the flow rate, power consumption, heat exchange efficiency, specific heat capacity, capacity, required heat amount, and residence time as control information for causing the water production unit 23 to perform temperature adjustment processing. Specifically, the example in FIG. 11C shows that the flow rate is "14" (mL / sec), the power consumption is "1.2" (kWh), and the heat exchange efficiency is "47" (J / (mL×°C)). It also shows that the capacity is "5" (L), the required heat amount is "294" (kJ), and the residence time is "375" (seconds).

[0085] 12A to 12C show specific examples of water adjustment information used in the carbonation adjustment process. The water adjustment information shown in FIG. 12A indicates that the adjustment target for carbonation strength, which is an adjustment item that is the subject of the carbonation adjustment process, is "2." In other words, in the carbonation adjustment process, adjustment is made to make the carbonation strength "2." As described above, the water production device 1 measures the properties of the raw water at each stage of the water production process and updates the water adjustment information as needed based on the measurement results, but the water adjustment information can also include the temperature value of the raw water itself before the temperature adjustment process.

[0086] 12B includes information regarding the amount of carbonation strength adjustment, such as the carbonation strength before the carbonation adjustment process, the difference in carbonation strength that requires adjustment, the level of impact when water is released, and the adjustment level. Specifically, the example in FIG. 12B shows that the carbonation strength before the carbonation adjustment process is "0," the difference in carbonation strength that requires adjustment is "2," the level of impact when water is released is "1," and the adjustment level is "3."

[0087] 12C also includes the mineral ion concentration and injection time as control information for causing the water production unit 23 to perform a carbonation adjustment process. Specifically, the example in FIG. 12C shows that the mineral ion concentration is "220" (mg / L) and the injection time is "5" (seconds).

[0088] [Specific Configuration of Water Production Apparatus 1] Figure 13 is a diagram showing an example of the specific configuration of the water production apparatus 1. The water production apparatus 1 shown in Figure 13 includes water measurement units 22-2 to 22-12, which are comprised of various sensors, a water production unit 23-1 that performs pre-processing, and a water production unit 23-2 that performs additive adjustment and addition processing. Also shown are a water production unit 23-3 that performs pH adjustment processing, a water production unit 23-4 that performs temperature adjustment processing, and a water production unit 23-5 that performs carbonation adjustment processing. Also shown are loop piping 24-1 to 24-7, a carbon filter 25, a pump 26, and a proportional solenoid valve 27.

[0089] 13, upstream of the RO filter 231, through which the raw water passes as a pretreatment step, a water measuring unit 22-2 is provided to measure the properties of the raw water before pretreatment. The water measuring unit 22-2 measures the TDS (total dissolved solids) content (mg / L) in the raw water. As a result, if the TDS (total dissolved solids) content is too high and the RO filter 231, which passes the raw water, is burdened, the raw water is discharged without passing through the RO filter 231.

[0090] In addition, a water measuring unit 22-4 is provided downstream of the RO filter 231 to measure the properties of the raw water (RO purified water) after pretreatment. As a result, the water measuring unit 22-2 measures the properties of the raw water before pretreatment, and the water measuring unit 22-4 measures the properties of the raw water (RO purified water) after pretreatment, making it possible to compare the properties of the raw water before and after pretreatment. As a result, the performance of the pretreatment can be evaluated.

[0091] However, since the results of the pretreatment may be insufficient, the water production apparatus 1 is provided with loop pipes 24-1 and 24-2 that enable retreatment of the pretreatment. This allows retreatment of both the RO wastewater and the RO purified water. As a result, the amount of water ultimately discharged as RO wastewater is reduced, and a large amount of RO purified water can be obtained. This also allows for improvement in the quality of the RO purified water.

[0092] The determination of whether the RO wastewater can be reprocessed after pretreatment is made based on the TDS (total dissolved solids) content obtained from the measurement results of the water measurement unit 22-3, which measures the properties of the RO wastewater. Specifically, RO wastewater whose TDS (total dissolved solids) content does not exceed a predetermined threshold is determined to be reprocessable and is discharged into the loop piping 24-1. The RO wastewater discharged into the loop piping 24-1 is reprocessed via a branching mechanism and a confluence mechanism (not shown). In contrast, RO wastewater whose TDS (total dissolved solids) content exceeds a predetermined threshold is determined to be unprocessable and is discharged without being discharged into the loop piping 24-1.

[0093] Furthermore, the determination of whether the RO purified water requires retreatment of the pretreatment is made based on the TDS (total dissolved solids) content obtained from the measurement results of the water measurement unit 22-2. Specifically, RO purified water whose TDS (total dissolved solids) content exceeds a predetermined threshold is determined to be RO purified water requiring retreatment and is flowed into the loop piping 24-2. The RO purified water flowed into the loop piping 24-2 is reprocessed via a branching mechanism and a merging mechanism (not shown). In contrast, RO purified water whose TDS (total dissolved solids) content does not exceed a predetermined threshold is determined to be RO purified water not requiring retreatment and is circulated as raw water (RO purified water) to be subjected to the next additive treatment without being flowed into the loop piping 24-2.

[0094] When pretreatment is performed using each of the loop pipes 24-1 and 24-2, the pretreatment can be easily performed by controlling the pressure of the raw water. Specifically, the proportional solenoid valve 27 controls the flow rate of the raw water based on the raw water pressure measurement results obtained by the pressure sensor of the water measurement unit 22-2 provided upstream of the RO filter 231.

[0095] Additionally, upstream of the water measuring unit 22-2, a pump 26 capable of PWM (Pulse Width Modulation) control is provided. By PWM controlling the pump 26, the flow rate of raw water flowing downstream from the pump 26 can be controlled. This also makes it possible to control the pressure applied to the RO filter 231, thereby improving the efficiency of pretreatment by the RO filter 231. For example, by controlling the pressure applied to the RO filter 231 to be higher, the permeation speed can be increased. On the other hand, if the pressure is too high, the RO filter 231 is burdened and easily worn out, so control can be performed taking into account the permeation speed by the RO filter 231 and the lifespan of the RO filter 231.

[0096] A carbon filter 25 is provided upstream of the pump 26. The carbon filter 25 is a filter that removes impurities by filtering the incoming raw water. By providing the carbon filter 25 upstream of the pump 26, it is possible to apply concentrated pressure to the RO filter 231 while suppressing the impact on the carbon filter 25. By increasing the pressure applied to the RO filter 231, it is possible to reduce the amount of RO wastewater and increase the amount of RO purified water.

[0097] Additionally, upstream of the carbon filter 25, a water measuring unit 22-1 equipped with a flow rate sensor that measures the flow rate of raw water entering the water production apparatus 1 is provided. This makes it possible to, for example, set an upper limit on the flow rate of raw water entering the water production apparatus 1 and keep the flow rate of raw water entering the water production apparatus 1 constant. As a result, the flow rate of raw water entering the water production apparatus 1 can be adjusted depending on the application of the water production apparatus 1.

[0098] Furthermore, downstream of the water production unit 23-2 that performs the addition treatment, a water measurement unit 22-5 is provided that measures the properties of the raw water after the addition treatment. As a result, the water measurement unit 22-4 measures the properties of the raw water (RO purified water) after pretreatment (before the addition treatment), and the water measurement unit 22-5 measures the properties of the raw water after the addition treatment, making it possible to compare the properties of the raw water before and after the addition treatment. As a result, the performance of the addition treatment can be evaluated.

[0099] Furthermore, downstream of the water production unit 23-3 that performs the pH adjustment treatment, a water measurement unit 22-7 is provided that measures the properties of the raw water (alkaline water) after the pH adjustment treatment. As a result, the above-mentioned water measurement unit 22-5 measures the properties of the raw water after the addition treatment (before the pH adjustment treatment), and the water measurement unit 22-7 measures the properties of the raw water (alkaline water) after the pH adjustment treatment, so that the properties of the raw water before and after the pH adjustment treatment can be compared. As a result, the performance of the pH adjustment treatment can be evaluated.

[0100] Furthermore, downstream of the water production unit 23-4, which performs the temperature adjustment process, there is provided a water measurement unit 22-8 that measures the properties of the raw water after the temperature adjustment process. As a result, the water measurement unit 22-7 measures the properties of the raw water (alkaline water) after the pH adjustment process (before the temperature adjustment process), and the water measurement unit 22-8 measures the properties of the raw water after the temperature adjustment process, so that the properties of the raw water before and after the temperature adjustment process can be compared. As a result, the performance of the temperature adjustment process can be evaluated.

[0101] Furthermore, downstream of the water production unit 23-5 that performs the carbonation adjustment treatment, a water measurement unit 22-9 is provided that measures the properties of the raw water after the carbonation adjustment treatment. As a result, the above-mentioned water measurement unit 22-8 measures the properties of the raw water after the temperature adjustment treatment (before the carbonation adjustment treatment), and the water measurement unit 22-9 measures the properties of the raw water after the carbonation adjustment treatment, making it possible to compare the properties of the raw water before and after the carbonation adjustment treatment. As a result, the performance of the carbonation adjustment treatment can be evaluated.

[0102] Additionally, downstream of the water measurement unit 22-9, which measures the properties of the raw water after carbonation adjustment, is a water measurement unit 22-10 that measures the properties of the target water discharged from the water production apparatus 1. This ensures the final quality of the target water. Specifically, if the TDS (total dissolved solids) content obtained from the measurement results of the target water properties by the water measurement unit 22-10 and the mineral content estimated from the water specification information are the same or approximately the same, it is determined that the water production apparatus 1 has successfully produced the target water. On the other hand, if the TDS (total dissolved solids) content obtained from the measurement results of the target water properties by the water measurement unit 22-10 deviates from the mineral content estimated from the water specification information, it is determined that the production of the target water by the water production apparatus 1 has failed, and the target water is discharged.

[0103] The water production unit 23-2, which performs the addition process, is also equipped with a water measurement unit 22-11, which is comprised of multiple water quality sensors. The water measurement unit 22-11 detects mineral concentrates whose TDS (total dissolved solids) content exceeds a predetermined threshold. Therefore, the time during which the water measurement unit 22-11 detects the mineral concentrate is the time during which the mineral concentrate is being dripped, and the dripping time of the mineral concentrate can be estimated from the time during which the water measurement unit 22-11 detects the mineral concentrate. The dripping time of the mineral concentrate can also be estimated by comparing the TDS (total dissolved solids) content measured by each of the multiple water quality sensors.

[0104] Furthermore, the water production unit 23-2 that performs the addition process is provided with a water measurement unit 22-11 consisting of multiple water quality sensors, which allows for correction of variations in the concentration of the mineral concentrate dripped into the raw water. Incidentally, variations in the concentration of the mineral concentrate can be caused, for example, by variations in the amount of mineral powder dispensed when preparing the mineral concentrate by dissolving mineral powder, or by the ability of the user to prepare the mineral concentrate. Furthermore, for example, when purchasing mineral concentrate, variations can be caused by differences in the lot of the purchased mineral concentrate, or by changes in concentration due to evaporation or other factors that occur inside the tank 232 in which the mineral concentrate is stored.

[0105] Furthermore, the tank 232 storing the mineral concentrate in the water production unit 23-2 that performs the addition process is provided with a water measurement unit 22-12 consisting of a quantity sensor. The water measurement unit 22-12 measures the weight of the mineral concentrate stored in the tank 232. Therefore, the volume of the mineral concentrate can be calculated from the weight of the mineral concentrate stored in the tank 232. Furthermore, the consumption amount of the mineral concentrate can be calculated from the weight of the mineral concentrate stored in the tank 232. This makes it possible to confirm whether the mineral concentrate is being dripped in accordance with the contents of the water adjustment information. Furthermore, the pump 233 for dripping the mineral concentrate is capable of PWM control. This allows the amount of mineral concentrate dripped to be controlled.

[0106] Furthermore, as with the pretreatment described above, each of the addition treatment and pH adjustment treatment is provided with the following loop piping, allowing for retreatment. For example, the water production apparatus 1 is provided with loop piping 24-3, which allows for retreatment of the addition treatment. This allows for retreatment of raw water to which mineral components have been added, for example. As a result, if the addition of mineral components is insufficient, the addition treatment is retreated, thereby improving the accuracy of the mineral component content.

[0107] The decision as to whether or not to reprocess the added water is made based on the TDS (total dissolved solids) content obtained from the measurement results of the water measurement unit 22-5, which measures the properties of the raw water that has been added. Specifically, if the TDS (total dissolved solids) content does not match the water adjustment information, it is determined that reprocessing is required, and the raw water is sent to the loop piping 24-3. The raw water sent to the loop piping 24-3 is reprocessed via a branching mechanism and a merging mechanism (not shown). On the other hand, if the TDS (total dissolved solids) content matches the water adjustment information, it is determined that reprocessing is not required, and the raw water is sent to the next pH adjustment process without being sent to the loop piping 24-3.

[0108] Although not shown in Fig. 13, a temporary storage tank may be provided midway along the loop piping 24-3. In this case, when a large amount of raw water is to be retreated at once, the raw water can be treated sequentially by temporarily storing it in the temporary storage tank.

[0109] The water production apparatus 1 is also provided with a loop pipe 24-4 that allows for reprocessing of the pH adjustment process. This allows for reprocessing of raw water that has undergone pH adjustment. As a result, if the pH adjustment is insufficient, the pH adjustment process can be carried out again, thereby improving the accuracy of the pH adjustment.

[0110] The decision as to whether or not to re-process the pH adjustment process is made based on the pH value obtained from the measurement results of the water measurement unit 22-7. Specifically, if the pH value does not match the water adjustment information, it is determined that re-processing is required, and the raw water is sent to the loop piping 24-4. The raw water sent to the loop piping 24-4 is re-processed via a branching mechanism and a merging mechanism (not shown). On the other hand, if the pH value matches the water adjustment information, it is determined that re-processing is not required, and the raw water is circulated as the raw water to be subjected to the next temperature adjustment process without being sent to the loop piping 24-4.

[0111] Although not shown in Fig. 13, a temporary storage tank may be provided midway along the loop piping 24-4. In this case, when a large amount of raw water is to be retreated at once, the raw water can be treated sequentially by temporarily storing it in the temporary storage tank.

[0112] The water production apparatus 1 is also provided with a loop pipe 24-5 that allows for the reprocessing of acidic water produced as a by-product of the pH adjustment process. This makes it possible to reprocess the acidic water produced as a by-product of the pH adjustment process. As a result, acidic water that would normally be discharged can be reprocessed, so a large amount of alkaline water can be obtained with a small amount of discharged water.

[0113] The decision as to whether or not to re-adjust the pH of the acidic water is made based on the pH value obtained from the measurement results of the water measurement unit 22-6, which measures the properties of alkaline water that has been pH-adjusted. Specifically, if the pH value is weakly acidic and does not exceed a predetermined threshold, it is decided that re-treatment should be performed, and the water is discharged into the loop piping 24-5. On the other hand, if the pH value is strongly acidic and exceeds a predetermined threshold, it is decided that re-treatment should not be performed, and the water is discharged without being discharged into the loop piping 24-5.

[0114] Furthermore, similar to the pretreatment described above, the temperature adjustment treatment and the carbonation adjustment treatment each have the following loop piping, which allows for retreatment. For example, the water production apparatus 1 is provided with loop piping 24-6, which allows for retreatment of the temperature adjustment treatment. This makes it possible to retreatment of raw water whose temperature has been adjusted, for example. As a result, if the temperature adjustment is insufficient, the temperature adjustment treatment is retreated, thereby improving the accuracy of the temperature adjustment.

[0115] The decision as to whether to reprocess the temperature adjustment process is made based on the temperature value obtained from the measurement results of the water measurement unit 22-8, which measures the properties of the raw water that has been subjected to the temperature adjustment process. Specifically, if the temperature value does not match the water adjustment information, it is determined that reprocessing is required, and the raw water is flowed into the loop piping 24-6. The raw water flowed into the loop piping 24-6 is reprocessed via a branching mechanism and a merging mechanism (not shown). On the other hand, if the temperature value matches the water adjustment information, it is determined that reprocessing is not required, and the water is circulated for the next carbonation adjustment process without being flowed into the loop piping 24-6.

[0116] The water production apparatus 1 is also provided with a loop pipe 24-7 that allows for reprocessing of the carbonation adjustment process. This allows, for example, reprocessing of raw water that has already been carbonation adjusted. As a result, if the carbonation adjustment is insufficient, reprocessing of the carbonation adjustment process is performed, thereby improving the accuracy of the carbonation adjustment.

[0117] The decision as to whether to reprocess the carbonation adjustment process is made based on the carbonation strength value obtained from the measurement results of the water measurement unit 22-7, which measures the properties of the raw water that has been carbonation adjusted. Specifically, if the carbonation strength value does not match the water adjustment information, it is determined that reprocessing is required, and the raw water is sent to the loop piping 24-7. The raw water sent to the loop piping 24-7 is reprocessed via a branching mechanism and a merging mechanism (not shown). On the other hand, if the carbonation strength value matches the water adjustment information, it is determined that reprocessing is not required, and the water is circulated without being sent to the loop piping 24-7, and if the quality is guaranteed as the above-mentioned target water, it is sent out.

The system then displays a suggestion for improvement, stating, "Changing the power source used for the electrolytic cell and raising the upper limit of the control current will produce water closer to the target value than currently." The system also displays the reason for the judgment result of "×" (failure) for the target water "Home / Water Purifier" and "Home / Low-Cost" as "The pH was not adjusted, resulting in water with a pH far from the target value." The system also displays a suggestion for improvement, stating, "Adjusting the pH will produce water closer to the target value than currently." Users can easily produce the desired target water by referring to the suggestions for improvement.

[0135] <Advantageous Effects of the Present Embodiment> According to the above-described embodiment, it is possible to generate information for producing water from raw water that meets the user's purpose. The water producing device 1 can be installed in disaster sites, developing countries, and the like.

[0136] <Others> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and modifications, improvements, etc. within the scope of achieving the object of the present invention are included in the present invention. For example, the specific examples shown in each of Figures 6 to 18 are merely examples for achieving the object of the present invention, and are not particularly limited.

[0137] In the above-described specific example, mineral components contained in the water specification information of the destination water are first removed in a pretreatment process and then added in a subsequent addition process. In other words, the source water is purified before the destination water is produced. However, this configuration is not limited to this. If the destination water specification information contains minerals and the source water also contains minerals, it is not necessary to remove the minerals in the pretreatment process. In other words, instead of purifying the source water before producing the destination water, water adjustment information that takes into account the offset of the components may be generated based on the measurement results of the source water components and the destination water specification information.

[0138] Furthermore, the above-described series of processes can be executed by hardware or software. In other words, the above-described functional configuration is merely an example and is not particularly limited. In other words, it is sufficient for the information processing system to be provided with a function that can execute the above-described series of processes as a whole, and the type of functional block used to realize this function is not particularly limited to the above-described example.

[0139] The location of the functional blocks is not particularly limited and may be arbitrary. For example, the functional blocks of the water production device 1 may be transferred to another device, or the functional blocks of another device may be transferred to a server. Furthermore, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination of both.

[0140] When a series of processes is executed by software, the programs constituting the software are installed onto a computer or the like from a network or a recording medium. The computer may be a computer incorporated into dedicated hardware. The computer may also be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

[0141] The recording medium containing such a program may be configured as a removable medium (not shown) that is distributed separately from the device main body in order to provide the program to users, etc., or may be configured as a recording medium that is pre-installed in the device main body and provided to users, etc. Since the program can be distributed via a network, the recording medium may be installed in or accessible from a computer that is connected or connectable to the network.

[0142] In this specification, the steps describing the program recorded on the recording medium include not only processes that are performed in chronological order, but also processes that are not necessarily performed in chronological order but are performed in parallel or individually. Also, in this specification, the term "system" means an overall device composed of multiple devices or multiple means, etc.

[0143] In other words, the water production system to which the present invention is applied can take various forms having the following configurations: (1) That is, the water production system S to which the present invention is applied is a water production system comprising: water adjustment information generating means (e.g., water adjustment information generating unit 33 in FIG. 3 ) that generates water adjustment information for adjusting raw water having predetermined properties to produce destination water, based on water specification information relating to the specifications of the destination water, which is water for a predetermined purpose; additive adjusting means (e.g., additive adjusting unit 35 in FIG. 3 ) that adjusts additives (e.g., the mineral components described above) to be added to the raw water, based on the water adjustment information; and addition means (e.g., addition unit 36 ​​in FIG. 3 ) that adds the additives to the raw water to produce the destination water from the raw water.

[0144] (2) The apparatus may further include a pH adjusting unit (e.g., the water adjusting unit 37 in FIG. 3) that adjusts the pH of the raw water based on the water adjustment information. This allows the production of target water with a desired pH based on the water specification information.

By performing this pretreatment before the addition process, components unnecessary for the target water can be removed in advance.

[0146] (4) The water adjustment information generating means can also update the water adjustment information based on the water specification information and the results of measuring the properties of the raw water (e.g., the measurement results from the water measuring units 22-2 to 22-12 in FIG. 10). This allows the content of various adjustment processes that affect the properties of the destination water produced based on the water specification information to be optimized. Specifically, for example, a pH adjustment process can be performed after an addition process. Alternatively, an addition process can be performed after a pH adjustment process. Furthermore, the addition process and the pH adjustment process can be performed simultaneously.

[0147] (5) The apparatus may further include a temperature adjusting unit (for example, the water adjusting unit 37 in FIG. 3) that adjusts the temperature of the raw water based on the water adjustment information. This allows the production of target water at a desired temperature.

[0148] (6) The apparatus may further include a carbonation adjusting means (e.g., the water adjusting unit 37 in FIG. 3) that adjusts the carbonation to be injected into the raw water based on the water adjustment information. This allows the production of target water with a desired hydrogen ion concentration.

[0149] (7) The apparatus further includes a water specification information acquisition unit (e.g., the water specification information acquisition unit 31 in FIG. 3 ) that acquires the water specification information from a user, and the water adjustment information generation unit generates the water adjustment information based on the acquired water specification information, thereby producing target water based on the water specification information desired by the user.

[0150] Furthermore, the water production apparatus to which the present invention is applied can take various forms having the following configurations: (8) That is, the water production apparatus 1 to which the present invention is applied is a water production apparatus having: water adjustment information generating means for generating water adjustment information for adjusting raw water having predetermined properties to produce destination water, based on water specification information relating to the specifications of the destination water, which is water for a predetermined purpose; additive adjusting means for adjusting additives to be added to the raw water, based on the water adjustment information; and adding means for adding the additives to the raw water to produce the destination water from the raw water.

[0151] Furthermore, the water generating method to which the present invention is applied can take various forms having the following configurations: (9) That is, the water generating method to which the present invention is applied is a water generating method executed by a water generating apparatus, and includes the steps of: generating water adjustment information for adjusting raw water having predetermined properties to produce target water, based on water specification information relating to the specifications of the target water, which is water for a predetermined purpose; adjusting additives to be added to the raw water, based on the water adjustment information; and adding the additives to the raw water to produce the target water from the raw water.
