Description

Tank filtration device using nitrification and tank filtration device management system

[0001] The present invention relates to a filtration device and a management system for an aquarium, and more particularly, to a filtration device for an aquarium using nitrification, which purifies toxic secretions resulting from the growth of ornamental fish raised in the aquarium through nitrification, while supplying nitrates and the like by the nitrification as nutrients for ornamental plants, thereby purifying the breeding water stored in the aquarium in an eco-friendly manner, and which notifies in real time from a remote location of changes in the water quality of the breeding water stored in the aquarium to enable urgent countermeasures to be taken, and which effectively manages the aquarium by purifying toxic secretions resulting from the growth of ornamental fish raised in the aquarium through nitrification, while supplying nitrates and the like by the nitrification as nutrients for ornamental plants.

[0002] Aquariums are commonly used at home to raise ornamental fish like goldfish and tropical fish. Because the water in these tanks is easily contaminated by fish waste and secretions, a filtration system is used to purify the water.

[0003] Ornamental fish kept in tanks accumulate food scraps and fish waste on the bottom after a certain period of time. As these are broken down by bacteria, toxic substances such as ammonia, nitrite, and nitrate dissolve into the water, which can cause the ornamental fish to become stressed or even die from poisoning.

[0004] As IT technology advances, the Internet of Things (IoT), a technology or environment that attaches sensors to objects and exchanges data in real time over the Internet, is being applied in various fields.

[0005] The Internet of Things (IoT) is a new environment where everything is connected through the Internet without any restrictions on time, place, or objects. It refers to an environment where all objects are given an Internet address and each piece of information is shared and communicated through the Internet via mobile devices.

[0006] Accordingly, IoT technology can collect big data on various objects, store it in the cloud, and then analyze and utilize it using artificial intelligence. IoT technology is primarily applied in the home, connecting objects like door locks, gas sensors, fire sensors, and boilers to the Internet and allowing remote operation.

[0007] Meanwhile, aquariums are used at home to raise ornamental fish like goldfish and tropical fish. Because the water in these tanks is easily contaminated by fish waste and secretions, filtration systems are used to purify the water.

[0008] Ornamental fish kept in tanks accumulate food scraps and fish waste on the bottom after a certain period of time. As these are broken down by bacteria, toxic substances such as ammonia, nitrite, and nitrate dissolve into the water, which can cause the ornamental fish to become stressed or even die from poisoning.

[0009] Korean Patent No. 81340 (Registration Date: March 28, 2022) includes a chamber installed inside a water tank and having a plurality of water passage holes formed therein to allow water to pass between the inside and the outside, a filter installed on the outer surface of the chamber so that water flowing into the chamber through the water passage holes is purified, an air transport pipe installed so that air is transported into the chamber, a water flow forming tank installed on the lower side of the inside of the chamber so that air transported by the air transport pipe is discharged inside, and water flows into the inside through a water flow inlet formed on the side as the air bubbles rise, a bubble buoyancy pipe connected to the upper side of the water flow forming tank so that the air bubbles inside the water flow forming tank rise and are discharged to the upper side of the chamber outside, and a stand mounted on the upper part of the chamber so that the chamber is supported on the water tank, the water flow forming tank having a cylindrical shape with an upper part having an upper and lower narrow portion and a body having a plurality of water flow inlets formed therethrough at regular intervals along the circumference of the lower part, A filtering device for a water tank is disclosed, which includes a cylindrical bubble-generating drum that is installed and erected inside a body and has a plurality of bubble-generating holes formed on an upper end surface so that bubbles are formed as air is introduced into the drum through an air conveying tube and the air inside is discharged.

[0010] However, the conventional aquarium filtering device as described above uses bubbles to form a water current in the tank's breeding water and purifies foreign substances contained in the water current through a filter medium. However, purification through such a filter medium has limitations in removing toxic substances such as ammonia, nitrite, and nitrate dissolved in the breeding water, and there is a serious problem that if the toxic substances that are not filtered dissolve above a certain concentration, the ornamental fish die.

[0011] Meanwhile, sudden, unexpected changes in the tank's condition can pose a fatal risk to ornamental fish. In such cases, it's crucial to detect and eliminate the hazard as quickly as possible. However, this can be difficult to resolve if the tank manager is absent or located remotely.

[0012] In order to solve the above-mentioned problem, the present invention provides a filtering device for a tank that utilizes nitrification, which can be conveniently used by replenishing only water that is naturally dried in the tank by purifying toxic substances dissolved in the breeding water through a biological purification method.

[0013] In addition, the present invention aims to provide a filtering device for an aquarium that utilizes nitrification to provide nitrates and the like produced by a biological purification method as nutrients for ornamental plants, thereby enabling the growth of ornamental plants as well as ornamental fish.

[0014] In addition, the present invention aims to control the speed of purified water flow according to the concentration of toxic substances dissolved in the breeding water and to sterilize harmful bacteria dissolved in the breeding water with UV, thereby enabling the cultivation of ornamental fish and ornamental plants more easily and conveniently.

[0015] In addition, the purpose of this invention is to provide a management system for a tank filtration device that can notify a remote manager terminal in real time of a sudden change in the water quality of the water stored in the tank that could be fatal to the ornamental fish, thereby enabling the preparation of an emergency response.

[0016] In addition, the present invention aims to provide a management system for a filtering device for a tank that can be conveniently used by replenishing only water that is naturally dried in the tank by purifying toxic substances dissolved in the breeding water through a biological purification method.

[0017] In addition, the present invention aims to provide a management system for a filtering device for an aquarium that can grow ornamental plants as well as ornamental fish by providing nitrates and the like produced by a biological purification method as nutrients for ornamental plants.

[0022] As an example, the underwater motor unit includes an underwater motor having an intake port for receiving the breeding water purified through the nitrification unit and an outlet for discharging the water at a constant speed into the tank, and the underwater motor is controlled by current according to a control signal from the control unit, and may include a sensor unit for measuring the temperature of the breeding water and outputting the temperature to the control unit, and a display panel for displaying the measurement signal of the sensor unit through the control unit.

[0023] As an example, the sensor unit may further include at least one sensor for measuring ammonia concentration, pH, and dissolved oxygen.

[0024] In order to achieve the above object, the management system of the filtration device for an aquarium according to the present invention may be configured to include a filtration device for an aquarium including a sensor unit for measuring the water quality of the aquarium, an IoT communication unit for transmitting sensing data generated by the sensor unit, and a nitrification unit for purifying the aquarium through an ammonia-oxidation process and a nitrification process for oxidizing ammonia emitted by ornamental fish grown in the aquarium into nitrate through nitrification process, a monitoring communication unit for receiving sensing data from the sensor unit of the filtration device for an aquarium, a monitoring server including a water quality analysis unit for analyzing the sensing data, and an administrator terminal including an administrator communication unit for communicating with the monitoring server, an administrator input unit for receiving information and control commands for an administrator, and a display unit for outputting the water quality state received from the monitoring server.

[0025] As an example, the monitoring server may be configured to include an IoT setting unit for identifying a water tank filter, a monitoring DB for storing sensing data, an administrator DB for identifying an administrator terminal, and a water quality status analysis unit for analyzing the sensing data.

[0026] As an example, a filtering device for an aquarium may include a mounting frame that is hung on one side wall of an aquarium for breeding ornamental fish and submerged in breeding water, a planting section that is coupled to the mounting frame and has a planting compartment in which ornamental plants are planted, a submerged motor section that introduces breeding water into the planting section, purifies it through a nitrification section, and discharges it into the aquarium, and a pair of hexahedral nitrifying bacteria medium frames that are symmetrical to each other and are inserted into and received in the planting compartment, wherein the nitrifying bacteria medium frames have a medium net having a plurality of porous stones filled on the inside and a mesh smaller than the outer diameter of the porous stones on the surface, and an ornamental plant mounting section that is curved inwardly is formed on one side where the ornamental plants are positioned, and the nitrifying section may be configured to include Nitrosomonas and Nitrobacter bacteria cultured on the inside of the nitrifying bacteria medium frames.

[0045] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings so that a person having ordinary knowledge in the same technical field can easily practice the present invention.

[0046] The present invention relates to a management system for a filtering device for a tank and a filtering device for a tank (100) that can provide nutrients for ornamental plants (80) such as nitrates produced by a biological purification method so that when a sudden change in the water quality of the breeding water stored in a tank (70) is expected to pose a fatal risk to ornamental fish, the system can be notified in real time through a remote management terminal (900) to take urgent countermeasures, and can enable the growth of not only ornamental fish but also ornamental plants (80).

[0047] FIG. 1 is a schematic configuration diagram of a management system for a water tank filtration device according to the present invention, and FIG. 2 is a schematic control block diagram of a management system for a water tank filtration device according to the present invention.

[0048] The management system of the water tank filter device according to the present invention can be configured to include a water tank filter device (100), a monitoring server (800), and an administrator terminal (900), as shown in FIGS. 1 and 2.

[0049] A filter device (100) for a water tank may be configured to include a sensor unit (150) for measuring the water quality of the breeding water stored in the water tank (70), a nitrification unit (300) for purifying the breeding water through ammonia and nitrification processes, a motor unit for circulating the breeding water so that a certain amount of algae is formed in the water tank (70), and a UV sterilization unit (500) for sterilizing and disinfecting the breeding water.

[0050] The monitoring server (800) may be configured to include a monitoring communication unit for receiving sensing data from a sensor unit (150) of a water tank filtration device (100) and communicating with an administrator terminal (900), an IoT setting unit for identifying the water tank filtration device (100), a monitoring DB for storing sensing data, an administrator DB for identifying the administrator terminal (900), and a water quality status analysis unit for analyzing the sensing data.

[0051] The administrator terminal (900) may be configured to include an administrator communication unit for communicating with the monitoring server (800), an administrator input unit for inputting information and control commands for the administrator, and a display unit for outputting water quality status received from the monitoring server (800).

[0052] In one embodiment, the administrator terminal (900) may be a mobile device such as a smartphone, PDA, or laptop.

[0053] A tank filter (100) is installed in a tank (70) containing breeding water, purifies the breeding water, senses the water quality of the breeding water, and generates sensing data. In addition, the sensing data is transmitted to a monitoring server (800) so that the water quality of the breeding water can be analyzed.

[0054] The monitoring server (800) analyzes the purification operation or changes in water quality of the water tank filter (100) and transmits the analysis data to the management terminal (900).

[0055] Accordingly, the management system of the water tank filtration device according to the present invention enables the water quality status of the water tank (70) to be checked in real time even when the manager managing the water tank (70) is located remotely from the water tank (70) or is absent for a long period of time.

[0056] In addition, it is possible to prevent in advance a fatal risk to ornamental fish being raised due to a rapid change in the water quality of the tank (70), thereby making the maintenance of the tank (70) more convenient.

[0057] FIG. 3 is a schematic control block diagram of a water tank filtration device (100) according to the present invention, FIGS. 4 to 10 show a water tank filtration device (100) according to the present invention, and FIGS. 11 to 13 show a nitrifying bacteria culture medium (90) used in a water tank filtration device (100) according to the present invention.

[0058] As an example, a water tank filter device (100) may be configured to include a filter unit (600), a UV sterilization unit (500), an underwater motor unit (400), a nitrification unit (300), an operation unit (200), an IoT communication unit (250), and a control unit (110), as shown in FIGS. 1 to 3.

[0059] The filter unit (600) serves to filter out foreign substances in the breeding water contained in the tank (70). That is, secretions from ornamental fish growing in the tank (70) or foreign substances flowing in from the outside are physically filtered by the filter unit (600).

[0060] For example, the filter unit (600) may use a non-woven filter or a sponge filter. Non-woven filters can be cleaned using tap water and have the advantage of being inexpensive.

[0061] The UV sterilization unit (500) irradiates UV rays into a sterilization chamber (35) formed inside the main body to sterilize harmful bacteria and moss that have entered the breeding water, thereby preventing the occurrence of white turbidity, green algae, moss, etc. Here, UV may use UV-C or UV-B, but in one embodiment of the present invention, UV-A is used.

[0062] The sterilization chamber (35) can be formed in various shapes, but it is preferable to form it so as to have a circulation passage through which breeding water is introduced, sterilized by UV, and then discharged to the water tank (70), and to form it so that the irradiated UV is not exposed to the outside of the water tank filter device (100).

[0063] Meanwhile, the UV sterilization unit (500) can be operated remotely according to a control signal input through the administrator terminal (900).

[0064] The underwater motor unit (400) forms a water current with a constant speed within the tank (70) for the purpose of filtering the breeding water. Here, it is preferable to use a current-controlled underwater motor (40). Water current that is not suitable for the fish species can cause stress to the fish, which can lead to diseases such as melting fins, and in severe cases, even death. The manager can easily select a water current suitable for the fish species, such as betta and guppies that prefer weak water currents, or corydoras that prefer strong water currents, through the control unit (200). In addition, the manager can operate the unit remotely according to a control signal input through the manager terminal (900).

[0065] The nitrification unit (300) is accommodated in a planting compartment (12) formed with a certain space, and receives breeding water circulated by the operation of the underwater motor unit (400) through the contaminated water inlet unit (15), and discharges the purified breeding water through the purified water discharge unit (16) as purified breeding water (710) after undergoing the ammonia and nitrification processes.

[0066] The nitrification function unit (300) is comprised of a group of nitrifying bacteria that oxidize ammonia into stable nitrate so that plants and other autotrophs can use it as a nitrogen source, and is accommodated in the planting compartment (12).

[0067] Meanwhile, ornamental plants (80) are planted in the planting compartment (12), and nitrifying bacteria are cultured in a nitrifying bacteria culture medium (90) using a biofilter formed of, for example, porous stone (98).

[0068] In the present invention, the ornamental plant (80) can be applied as long as it is an individual that can absorb nitrate as a nutrient by the nitrification function part (300), and is not limited to an ornamental tree or ornamental grass.

[0069] In the present invention, the nitrifying bacteria include ammonia-oxidizing bacteria that oxidize ammonia and nitrite-oxidizing bacteria that oxidize nitrite.

[0070] Ammonia oxidizing bacteria decompose ammonia into nitrite as shown in chemical formula 1 below.

[0071] [Chemical Formula 1]

[0072]

[0073] Nitrite-oxidizing bacteria convert nitrite into nitrate as shown in the chemical formula 2 below.

[0074] It is decomposed so that the ornamental plants (80) planted in the planting compartment (12) can absorb it.

[0075] [Chemical Formula 2]

[0076]

[0077] The control unit (110) controls the operation of the underwater motor unit (400) and the UV sterilization unit (500). In addition, the control unit (110) receives sensing data from the sensor unit (150) for measuring the temperature of the breeding water entering the planting compartment (12). The control unit (110) transmits the input sensing data to the monitoring server (800) via the IoT communication unit (250).

[0078] Accordingly, it is possible to check the temperature of the breeding water in real time to suit the nitrogen cycle that is taking place in the nitrification unit (300) and the characteristics of the ornamental fish grown in the tank (70).

[0079] Meanwhile, the sensor unit (150) may further include sensors for measuring ammonia concentration, pH, dissolved oxygen, nitrate concentration, and turbidity, and such sensing data is transmitted to the monitoring server (800) via the IoT communication unit (250).

[0080] The operation unit (200) can input a signal to control the operation of the underwater motor unit (400) through the control unit (110) to change the speed of the water flow.

[0081] In addition, it may include a display unit that controls the operation of the UV sterilization unit (500) or displays temperature, ammonia concentration, pH, dissolved oxygen, nitrate concentration, turbidity, etc. through the sensor unit (150).

[0082] FIG. 4 shows a filter device (100) for a water tank according to the present invention, FIG. 5 is an exploded view of a filter device (100) for a water tank according to the present invention, FIG. 6 is an operation part (200) and an upper surface of a filter device (100) for a water tank according to the present invention, FIG. 7 and FIG. 8 are side views of a filter device (100) for a water tank according to the present invention, and FIG. 9 is a cross-sectional view taken along line AA of FIG. 6.

[0083] In addition, Fig. 10 shows the flow of water formed inside the water tank filter device (100) according to the present invention.

[0084] A filter device (100) for a water tank according to an embodiment of the present invention may be configured to include, as shown in FIGS. 4 to 10, a planting section (10) having a square cylinder-shaped planting compartment (12) with an open upper surface for accommodating a nitrification unit (300) and planting ornamental plants (80), a mounting section frame (30) having a square cylinder-shaped front surface with an open front surface and a tank support (32) formed thereon to be connected to the planting section (10) and to be hung on one side wall of a water tank (70) at the rear surface, and a display frame (20) mounted on the upper opening surface of the planting section (10) and the upper portion of the mounting section frame (30).

[0085] It is preferable that the planting unit (10) be combined with the front cover (14) so ​​that it can be detached and installed separately from the planting compartment (12). Accordingly, when planting an ornamental plant (80) in the planting compartment (12), replacing a planted ornamental plant (80), or exchanging a separate planting compartment (12), it can be conveniently used by being separated from the front cover (14).

[0086] The food compartment (12) has a contaminated water inlet (15) formed on one side with multiple penetrations to allow the inflow of breeding water, and a purified water discharge (16) formed on the lower side with multiple penetrations to discharge purified breeding water.

[0087] Meanwhile, ornamental plants (80) are planted in the planting compartment (12), and a nitrification unit (300) is accommodated.

[0088] A sterilizing chamber (35) is formed between the contaminated water inlet (15) formed in the food chamber (12) and the holding frame (30) into which breeding water is introduced, and a filter unit (600) is mounted on the upper part of the sterilizing chamber (35).

[0089] The filter unit (600) is equipped with a filter handle (60) that is fastened to the upper part of the stand frame (30) and a non-woven fabric or sponge that is coupled to the filter handle (60). The filter unit (600) is preferably positioned adjacent to the contaminated water inlet (15) formed in the food compartment (12) on the inside of the sterilization compartment (35) so as to perform the function of filtering out foreign substances from the breeding water flowing into the sterilization compartment (35).

[0090] Accordingly, the filter made of non-woven fabric or sponge can be easily removed through the filter handle (60) for cleaning or replacement.

[0091] Meanwhile, a UV sterilization unit (500) is configured on one side of the sterilization chamber (35) to sterilize the introduced breeding water by irradiating it with UV. Here, it is preferable that the UV sterilization unit (500) be switched so that UV irradiation is forcibly stopped when the planting unit (10) and the holding unit frame (30) are separated.

[0092] The lower part of the sterilization chamber (35) is separated by a barrier wall (36) so that a water flow with a constant speed is formed in the introduced breeding water.

[0093] Here, a plurality of water inlet ports (34) are formed on one side of the support frame (30) to allow water to flow into the sterilization chamber (35).

[0094] An underwater motor (40) can be mounted between the lower surface of the food compartment (12) and the lower part of the support frame (30).

[0095] The underwater motor (40) receives purified breeding water from the planting compartment (12) through the purified water discharge port (16) into the suction port (42) and discharges it through the discharge port (44) formed on the other side.

[0096] The underwater motor (40) operates at different rotation speeds according to the control signal of the control unit (110), thereby changing the speed of the water current formed in the breeding water.

[0097] In addition, the operation of the underwater motor (40) can be controlled remotely according to a control signal input through the administrator terminal (900).

[0098] The breeding water discharged through the discharge port (44) of the underwater motor (40) is discharged through the purified water discharge pipe (50) mounted on the other side of the mounting frame (30).

[0099] The purified water discharge pipe (50) is rotatably connected to a connector (54) mounted on a mounting frame (30) so that the discharge direction can be freely adjusted. In addition, the connector (54) and the discharge port (44) of the underwater motor (40) are connected through a connecting pipe (52).

[0100] The display frame (20) includes a display panel (22) and an operation unit (200) composed of a plurality of buttons.

[0101] The control unit (200) may include a water flow control button (24), a UV lamp button (25), as shown in FIG. 6, and may include a display window (23) that displays the temperature of the breeding water measured through the sensor unit (150) and the speed of the underwater motor (40).

[0102] Here, the speed of the underwater motor (40) can be configured to be displayed as high, medium, low or RPM.

[0104] As an example, the nitrification unit (300) may be composed of a pair of symmetrical hexahedral nitrification bacteria unit substrates (90) as shown in FIGS. 11 to 13.

[0105] The nitrifying bacteria bed (90) has a surface composed of a bed net (92) and an inner surface filled with porous stones (98). In addition, it is preferable that an ornamental plant support section (94) curved inwardly is formed on one side where ornamental plants (80) are planted and positioned, and a bed net leg (96) for standing the plants at a certain height is included on the bottom surface.

[0106] Inside the nitrifying bacteria culture medium (90), ammonia-oxidizing bacteria and nitrite-oxidizing bacteria are kept alive.

[0107] Ammonia-oxidizing bacteria may be Nitrosomonas, and Nitrosomonas refers to a genus of Gram-negative bacteria that live a chemoautotrophic lifestyle using the inorganic substance ammonia (NH3) as an energy source and carbon dioxide (CO2) as a carbon source.

[0108] Nitrite-oxidizing bacteria may be Nitrobacter, and Nitrobacter is an aerobic autotrophic microorganism that uses nitrite as an energy source to oxidize it into nitrate and uses inorganic carbonate ions in water as a carbon source for cell synthesis.

[0109] The water tank filter device (100) according to the present invention configured as described above first separates the planting compartment (12) from the front cover (14) of the planting section (10).

[0110] As shown in Fig. 13, an ornamental plant (80) is placed in the central portion of a separated planting compartment (12), and an ornamental plant (80) is planted in the planting compartment (12) so that a nitrifying bacteria culture frame (90) is placed on both sides of the ornamental plant (80).

[0111] Here, in the nitrifying bacteria culture medium (90), Nitrosomonas and Nitrobacter bacteria must survive for nitrification to be performed.

[0112] After that, the food compartment (12) is fastened to the front cover (14), and the food section (10) is fastened to the support frame (30) to combine them.

[0113] A tank support (32) is installed on one side wall of the prepared tank (70) as shown in FIGS. 6 and 7.

[0114] The water tank filter device (100) according to the present invention, mounted inside the water tank (70), introduces the breeding water into the sterilization chamber (35) through the breeding water inlet (34) formed on one side of the support frame (30), as shown in Fig. 10. Here, the speed of the breeding water flow is changed according to the underwater motor (40).

[0115] The breeding water introduced into the sterilization chamber (35) is sterilized by UV irradiation of the UV sterilization unit (500), and foreign substances are filtered out by the filter unit (600).

[0116] The breeding water, which has been sterilized and foreign substances filtered out, flows into the nitrifying bacteria culture medium (90) through the contaminated water inlet (15) formed on one side of the planting compartment (12), and toxic substances such as ammonia in the introduced breeding water are oxidized into nitrate (salt) by the action of the nitrogen cycle and supplied as nutrients to the ornamental plants (80), thereby purifying the breeding water and discharging it through the purified water discharge port (16) formed on the lower surface of the planting compartment (12).

[0117] The discharged breeding water is introduced through the suction port (42) of the underwater motor (40) and is discharged to the water tank (70) through the discharge port (44) and connection pipe (52) of the underwater motor (40) and the purified water discharge pipe (50) provided on the other side of the support frame (30) to circulate.

[0118] Ammonia is toxic at a concentration of 0.1 to 0.2 mg / L, and the toxic concentration of NH3-N is generally reported to be toxic at a concentration of 0.6 to 2 mg / L.

[0119] Therefore, for safety, the ammonia concentration is recommended to be less than 0.05 mg / L.

[0120] Meanwhile, in the management system of the aquarium filtration device according to the present invention, ammonia concentration, pH, dissolved oxygen, nitrate concentration, and turbidity of the breeding water of the aquarium (70) are measured through the sensor unit (150) of the aquarium filtration device (100) to generate sensing data. In addition, the sensing data is transmitted to the monitoring server (800) through the IoT communication unit (250).

[0121] The monitoring communication unit of the monitoring server (800) receives sensing data and stores it in the monitoring DB.

[0122] Here, the IoT setting section of the monitoring server (800) stores the MAC number or identification number of the aquarium filter (100) so that it can be connected to the aquarium filter (100) in advance using a private IP, etc., and the aquarium filter (100) and the monitoring server (800) can communicate using protocols such as MQTT, HTTP (TCP), etc., but are not limited thereto.

[0123] The administrator DB of the monitoring server (800) stores authentication data in advance to identify the administrator terminal (900) for controlling the water tank filtration device (100), thereby enabling the water quality status of the water tank filtration device (100) to be checked.

[0124] As described above, the sensing data generated by measuring the ammonia concentration, pH, dissolved oxygen, nitrate concentration, and turbidity of the breeding water of the tank (70) through the sensor unit (150) of the tank filter (100) is transmitted from the monitoring server (800) and stored in the monitoring DB, and analyzed by the water quality status analysis unit.

[0125] For example, when the ammonia concentration measured in the water quality analysis unit approaches a level that may cause toxicity, an alarm is transmitted to the administrator terminal (900).

[0126] For example, the water quality condition analysis unit can request the control unit (110) of the tank filtration device (100) to check the nitrate concentration at 2-hour intervals. It determines whether the sensing data transmitted through the sensor unit (150) of the tank filtration device (100) is 7 ppm or more, and if it is less than 7 ppm, it determines that the water quality is normal, and if it is 7 ppm or more, it transmits a response plan to the management terminal (900) to discharge 0.45 L of breeding water and replenish the same amount of breeding water.

[0127] As an example, the water quality condition analysis unit can request turbidity in real time from the control unit (110) of the water tank filtration device (100). If the turbidity NTU is 1 or less as sensed data transmitted through the sensor unit (150) of the water tank filtration device (100), the control unit (110) of the water tank filtration device (100) transmits an alarm to the management terminal (900) so that the underwater motor unit (400) operates at stage 1, and if the turbidity NTU is 2 or less, the control unit (110) transmits an alarm to the management terminal (900) so that the underwater motor unit (400) operates at stage 2.

[0128] Meanwhile, ornamental fish cannot survive for a long time in water with a pH lower than 4 and a pH higher than 11, and the optimal pH for ornamental fish is between 6.5 and 9. If a value outside the optimal pH range is detected by the sensor unit (150), the monitoring server (800) can be configured to issue a warning through the administrator terminal (900) or to display it visually through the display unit.

[0134] In addition, the tank (70) can be managed by replenishing only the water that has been naturally dried in the tank (70) by purifying the toxic substances dissolved in the breeding water through a biological purification method, and by providing nitrates, etc. produced through a biological purification method, to the ornamental plants (80), so that not only the ornamental fish but also the ornamental plants (80) can grow, which has the effect of greatly improving the utility and convenience of use of the product.
