Description

The present invention relates to a filtration device, and more specifically, to a filtration device that can be easily used in an emergency such as a disaster.

In recent years, there has been a tendency for lifelines such as electricity, gas, and water to be stopped frequently due to earthquakes and typhoons, and as a countermeasure for that, each household or residents' association such as a neighborhood association Many places are purchasing and storing emergency generators for home use.

Examples of general household emergency generators include, for example, a gasoline generator, a generator using a storage battery in which electric power is stored in advance, and the like.

On the other hand, in an emergency, it is very important to secure domestic water such as drinking water. It is very important to secure water in the event of a disaster. In general, as a technique for securing domestic water for emergencies, for example, there is a technique related to a filtration device for obtaining domestic water from muddy water or the like using a filter.

However, gasoline generators deteriorate if they are stored without being used for a long period of time, so it is necessary to store them with sufficient care in order to maintain high quality gasoline. Then, when the use of the generator is finished, it is necessary to take precautions in use such that the gasoline remaining in the generator must be removed from the generator. If gasoline is left in the generator for a long period of time, the generator may break down due to deterioration of the gasoline, causing inconvenience that the generator must be sent for repair. That is, it takes a lot of time and effort to store gasoline, and if this is neglected, it is fully conceivable that the gasoline will not work in an emergency such as a disaster.

On the other hand, with storage batteries that store power in advance, it is not easy to store enough power required in an emergency with the current technological capabilities, and if the stored storage battery is used up, it cannot be used, and power in the event of a disaster, etc. It is extremely difficult to store electricity in the absence of electricity. In addition, since the electric power of the storage battery is reduced even if it is not used, there is a problem that the electric power must be stored regularly. On the other hand, although a technology of storing electric power by a solar cell is currently being developed, it is difficult to store electric power in case of bad weather, and there is a problem in the stability of electric power supply and electric power storage.

By the way, against the background of the above, a generator using a cassette cylinder has been proposed at present. A cassette cylinder has a flammable gas sealed inside and is generally used as fuel for cooking utensils such as a cassette stove. The gas sealed inside is burned in an internal combustion engine of a generator or the like. It is possible to obtain energy by letting it. The cassette cylinder can be stored for a longer period of time than gasoline or the like, and there is much less risk that the storage target will be reduced as compared with the above-mentioned storage battery.

On the other hand, in the filtration device using the above filter, since the filter is used, it is indispensable to replace the filter when a certain amount of water is treated. Therefore, there is a problem that once the stockpile of the filter is exhausted, it can no longer be used. In particular, since it is important for the filter to adsorb dirt, there is a problem that the consumption of the filter is very large compared to the amount of water to be filtered.

Therefore, in view of the above problems, it is an object of the present invention to provide an emergency filtration device capable of simpler long-term stable storage and less consumables.

As a result of diligent studies on the above problems, the present inventor has made it possible to reduce the size with a simple configuration and to achieve stable long-term storage more easily by combining a generator using a cassette cylinder and a spring type filter device. Therefore, we have completed the present invention by focusing on the fact that we can provide an emergency filtration device that can reduce the number of consumables.

That is, the filtration device according to one aspect of the present invention includes a cassette cylinder generator and a spring type filter device driven by using the electric power generated by the cassette cylinder generator.

Further, from this viewpoint, it is preferable to provide a reverse osmosis membrane device after the spring type filter device, although it is not limited.

Further, from this viewpoint, the spring-type filter device includes a spring-type filter, a support member for supporting the spring-type filter, and an internal space for accommodating the spring-type filter and the support member. It is preferable to have a body and a pump for delivering the undiluted solution to be processed into the internal space of the housing.

Further, in this case, the internal space of the housing is divided into a lower space and an upper space by a support member, a stock solution pipe is connected to the lower space, and a filtrate pipe is connected to the upper space. It is preferable that

Further, from this viewpoint, it is preferable to provide a hair collecting device in front of the spring type filter device, although it is not limited.

As described above, according to the present invention, it is possible to provide an emergency filtration device that can be more easily and stably stored for a long period of time and can reduce the number of consumables.

(Filtration device)
FIG. 1 is a diagram showing an outline of the configuration of a filtration device (hereinafter referred to as “the device”) 1 according to the present embodiment. As shown in this figure, the present device 1 includes a cassette cylinder generator 2 and a spring type filter device 3 that is driven by using the electric power generated by the cassette cylinder generator 2. A hair collecting device 5 is arranged in front of the spring type filter device 3, and a water source S to be treated is further in front of the hair collecting device 5. The flow of this process will be described later, but after removing coarse dust and the like from the water source S via the pipe T1 by the hair collecting device 5, fine impurities are removed by the spring type filter device 3. The water purified by the present device 1 is stored in the container C that stores the water via the pipe T2.

Further, in the present filtration device 1, a reverse osmosis membrane device 4 is provided after the spring type filter device 3. By using the reverse osmosis membrane device 4, it is possible to remove finer impurities after removing fine impurities.

First, in the present device 1, the cassette cylinder generator 2 refers to a generator capable of driving a cassette cylinder as fuel and supplying electric power.

The cassette cylinder used in the present apparatus 1 is a can-shaped cylinder in which a flammable gas (hereinafter, also simply referred to as “gas”) is sealed and can be completely sealed. The cassette cylinder is can-shaped and can be stored for an extremely long period of time once the gas is sealed. The cassette cylinder is provided with a portion called a stem at the tip portion, and by pressing the stem, the gas contained therein can be discharged to the outside (in the present device 1, the internal combustion engine in the generator 2). Since cassette cylinders are widely sold as fuel for cassette stoves, they are extremely easy to obtain, can be stored and stored in large quantities, and have little internal gas leakage. More specifically, unlike storage batteries, the decrease in electric power is extremely small, and unlike gasoline, there is much less risk of deterioration.

Further, the cassette cylinder generator 2 used in the present device 1 is a device capable of inserting the cassette cylinder and generating electricity using the gas accumulated in the cassette cylinder as fuel. Specifically, the cassette cylinder is installed in a socket provided in the cassette cylinder generator 2, and the gas is supplied as fuel to the internal combustion engine in the cassette cylinder generator 2 by pressing the stem. Specifically, gas is introduced into the internal combustion engine in the cylinder generator 2, and the gas is ignited and burned. Then, the piston provided in the internal combustion engine reciprocates in response to ignition and exhaust. Then, this reciprocating vibration can be converted into rotary motion to drive a generator such as a motor to generate electricity. The cassette cylinder generator 2 is not limited as long as it can generate electric power sufficient to drive the pump of the spring type filter device 3, and a commercially available cassette cylinder generator may be used. .. When the voltage for driving the pump is low, it is necessary to make adjustments such as connecting a plurality of boosters and generators in series to increase the voltage. As is clear from these descriptions, the cassette cylinder generator 2 is connected to the pump of the spring type filter device 3 to supply electric power. In this device 1, by using the cassette cylinder generator 2 as described above, fuel can be stably stored for a long period of time, there is no risk of deterioration unlike gasoline, etc., and gasoline, etc. remains in the device. The need for complete use and maintenance is greatly reduced in order to avoid failures due to this. Further, unlike a storage battery, it does not take time to replenish the electric power after the electric power is exhausted, and it can be used very easily. This maintenance-friendly and fuel availability is very important in the event of a disaster. The power of the generator 2 can also be used as the power of a pump for pumping water from the water source S and a pump for supplying water to the reverse osmosis membrane device 4.

Further, in the present device 1, the spring type filter device 3 is driven by using the electric power generated by the cassette cylinder generator as described above, and is a part having a main function of the filtration device.

Here, FIG. 2 shows a schematic cross-sectional view of the internal structure of the spring-type filter device 3 according to the present embodiment. As shown in this figure, the spring type filter device 3 includes at least a spring type filter 31, a support member 32 for supporting the spring type filter 31, and a housing 33 for accommodating the spring type filter 31 and the support member 32. It is composed of. As is clear from the description described later, impurities will remain on the outside of the spring type filter 31, and the liquid (filter liquid) from which the impurities have been removed will pass through the inside. That is, the outer space and the inner space are divided into the undiluted solution side and the filtrate side.

Further, the spring-type filter device 3 of the present embodiment has a housing 33 for accommodating the spring-type filter 31 and the support member 32 as described above. Further, the internal space 34 in the housing 33 is divided into two spaces, an upper space and a lower space, by the support member 32, and the support member 32 has a function as a partition plate. More specifically, a plurality of holes are formed in the support member 32, and by inserting and installing the spring type filter 31 in these holes, the internal space 34 in the housing 33 can be made into the spring type filter. It is possible to divide into a lower space 341 (hereinafter simply referred to as "lower space") and an upper space 342 of the spring type filter (hereinafter simply referred to as "upper space"). Further, in the spring type filter device 3, as will be described later, the filtration aid 35 is attached around the spring type filter 31 at the time of filtration. FIG. 3 shows an outline of the spring-type filter 31 according to the present embodiment, FIG. 4 shows a partial cross section thereof, and FIG. 5 shows an enlarged view of a partial cross-section around the spring-type filter 31 during filtration. At the time of filtration, the filtration aid 35 is arranged around the spring-type filter 31 to function as a filter layer. Specifically, the support member 32 separates the lower space 341 and the upper space 342 of the filter, and when the undiluted solution to be treated moves from the lower space 341 side to the upper space 342 side through the filter layer, insoluble impurities Cannot pass through the filter layer and remains in the filter layer, and is removed from the undiluted solution to be treated.

Here, the spring-type filter 31 of the spring-type filter device 3 will be described again. The spring-type filter 31 in the present device 1 is literally a spring-like filter. As shown in the above figure, the spring type filter 31 is a filter having a spring shape due to the wire rods 311 being wound in an annular shape and overlapping with a predetermined gap. Further, although not limited, the wire rod 311 of the spring type filter 31 in the spring type filter device 3 is provided with a protrusion 312 for ensuring the predetermined distance from the adjacent wire rod portion. It is possible to stably secure the average gap length of the spring type filter, more specifically, the distance between the wire rods.

Further, the average gap length (average of the intervals between the wires) of the spring type filter in the spring type filter device 3 can be appropriately set and is not limited, but may be in the range of 5 μm or more and 200 μm or less. It is preferably in the range of 10 μm or more and 150 μm or less. Within this range, insoluble impurities to be removed in the liquid can be efficiently removed by filtration.

Further, the material of the spring type filter 31 in the spring type filter device 3 is not limited as long as the shape can be maintained and the spring type filter device 3 can achieve a desired effect, for example, copper, iron, titanium, nickel and the like. Examples thereof include metal materials such as single metals and alloys such as stainless steel, and resin materials such as polystyrene, polypropylene, and polyvinyl chloride.

Further, the spring type filter 31 in the spring type filter device 3 can be easily realized by winding one wire rod 311 so as to draw an annular spiral. For example, an annular shape having a protrusion as described above is attached. It is also possible to realize the same structure by forming an annular laminate in which a plurality of wire rods and resin materials are laminated. Even in this case, the spring-type filter device 3 is included in the spring-type filter. That is, in the spring type filter device 3, the spring type filter 31 includes not only a wound body but also a structure of a laminated body in which an annular wire rod is laminated.

Further, in the present embodiment, as shown in the above figure, the spring type filter 31 may have a core material 313 at the center of the wire rod 311 and a pair of metal fittings for holding the core material 313 in the vicinity of both ends. good. By doing so, the wire rod can be held more stably. In particular, it is preferable that one of the metal fittings is connected to the support member 32 while having a structure in which a screw groove is formed in order to reduce the gap between the metal fitting and the support member 32. By doing so, a screw groove that fits into the support member 32 is also formed, and by fitting these, the support member 32 and the spring type filter 31 are stably fixed, and the lower space 341 and the upper space 342 are fixed. It is possible to reduce the gap between them.

Further, in the spring type filter device 3, as is clear from the above description, the number of spring type filters 31 may be one, but it is preferable that a plurality of spring type filters 31 are provided. Specifically, it is preferable that a large number of holes are formed in the support member 32, and the spring type filter 31 is inserted and fixed in each of the plurality of holes. By doing so, it becomes possible to improve the filtration efficiency.

Further, in the present device 1, of the internal space 34 in the housing 33, the lower space 341 and the upper space 342 of the spring type filter 31 in the housing 33 are provided with the stock solution pipe 36 and the filtrate pipe 37, respectively. ing. As a result, the undiluted solution mixed with the impurities to be treated can be supplied to the lower space 341, and the filtrate from which the impurities have been filtered can be discharged from the filtrate tube from the upper space 342.

As is clear from the description described later, in the spring type filter device 3 in the present device 1, the filtration aid is laminated around the spring type filter 31 until the filtration aid is sufficiently filtered. It is preferable to connect the stock solution pipe 36 and the filtrate pipe 37 to form a circulation path so that the contained water can be circulated in the apparatus. The circulation path preferably includes a valve for controlling the opening and closing of the path and a pump as a power source for circulation. The outline of the connection of the pipes of the spring type filter device 3 is shown in FIG.

As shown in this figure, in the spring type filter device 3, the piping is roughly divided into a stock solution pipe 36 and a filtrate pipe 37. The stock solution pipe 36 is also received on the front stage side of the spring type filter device 3, and is a pipe used to supply the stock solution to the lower space 341 of the spring type filter device 3. The undiluted solution pipe 36 is configured by providing a pump 361 and a valve 362 in the middle, and the undiluted solution can be supplied into the spring type filter device 3 by this pump, and is formed by this pipe by the valve 362. It is possible to control the opening and closing of the route. The pump 361 is connected to the cassette cylinder generator 2 and can send the undiluted solution to the spring type filter device 3. A waste liquid branch pipe 363 is further connected to the stock solution pipe 36 so that the used filtration aid can be discharged. Further, a valve 364 is connected to the waste liquid branch pipe 363 so that this path can be opened and closed.

Further, as shown in this figure, the filtrate tube 37 is a tube used to send out the filtrate filtered by the spring type filter device 3 to the outside. A valve 371 is arranged in the filtrate 37, and the opening and closing of this path can be controlled. Further, as described above, the circulation pipe 372 for forming the circulation path is branched and connected to the filtrate pipe 37, and the filtration aid tank 374, the pump 375, and the valve 376 are connected via the valve 373. Is connected to the stock solution pipe 36. As a result, the stock solution pipe 36 and the filtrate pipe 37 can be circulated. As is clear from this description, the filtration aid 35 is dispersed together with water in the filtration aid tank 374, and the spring-type filter is gradually circulated by circulating the water in which the filtration aid 35 is dispersed in this circulation path. The filtration aid 35 is laminated around the 31 to form a filter.

Further, in the present device 1, the stock solution pipe 36 and the filtrate pipe 37 are not limited, but some of them are made of metal or the like from the viewpoint of being able to withstand the negative pressure by suction or the like. While it is preferable that the tube is made of a hard material such as resin, it is also preferable that the tube is provided with a flexible portion in another part. Actually, in the event of a disaster, etc., there are various containers and locations for storing the undiluted solution to be treated, and it is very effective if the pipes can be moved appropriately according to the shape and location of the containers, and it is hard. If it is covered with a suitable material, the tube can be protected even if an external impact is applied. Further, when seawater is used as raw water, water can be easily obtained by immersing the tip of the undiluted solution pipe 36 (or the pipe T1 via the hair collecting device 5 connected to the undiluted solution pipe 36) in the sea without pumping out the seawater. Will be available. On the other hand, even when it has flexibility, it is preferable that it has strength and flexibility by weaving a metal or the like. By doing so, it becomes difficult to be crushed even when pressure due to suction is applied. Regarding the configuration, specifically, since it is less necessary to change the position of the above-mentioned circulation part, it is formed of a hard material such as resin or metal, while the part at the tip (inlet side or discharge side) is flexible. It is preferably made of a material having a property. As the tube that can withstand the load of suction but has flexibility, for example, a metal flexible hose or the like is preferably used, but the tube is not limited thereto.

Further, it is also preferable that a mesh-like filter is provided in the vicinity of the suction port of the stock solution pipe 36 on the suction side. This makes it possible to remove in advance large impurities such as stones, branches, and fallen leaves that have passed through the hair collecting device 5.

Further, it is preferable to provide a hair collecting device (hair catcher) 5 in the vicinity of the suction port of the stock solution pipe 36 on the suction side or in front of the suction port. By providing the hair collecting device 5, it is possible to remove large impurities such as stones, branches, and fallen leaves in advance, similar to the above filter. As the structure of the hair collecting device 5, a generally commercially available hair collecting device (hair catcher) can be used.

Further, the present device 1 includes a pump 361 as described above. The pump 361 is a device used for delivering a fluid in one direction, specifically, for delivering a stock solution to be processed. In this device 1, the lower space 341 is sent from the outside and the lower space 341 is sent to the upper space. At 342, a flow of air or liquid from the upper space 342 to the outside can be formed.

Further, in the present device 1, the pump 361 is connected to the cassette cylinder generator 2 as described above, and receives and drives the electric power generated by the cassette cylinder generator 2. The pump 361 may be arranged on the inlet side of the lower space or on the outlet side of the upper space. When it is arranged on the inlet side of the lower space, the flow is in the direction of supplying the fluid to the lower space, and when it is arranged on the discharge port side of the upper space, the flow is in the direction of sucking the fluid from the upper space.

The configuration of the pump used in the present device 1 is not limited as long as it has the above-mentioned functions, and may be a non-volume type pump that sends out a fluid by rotating the blades in the space inside the device. Further, it may be a positive displacement pump that sends out a fluid by engaging a plurality of gears or the like and rotating them, and further, it is a reciprocating vibration type pump that sends out a fluid by using the reciprocating vibration of a piston. You may.

Further, as described above, the filtration aid 35 for the spring type filter is arranged around the spring type filter 31 in the spring type filter device 3 at the time of filtration. More specifically, the filtration aid 35 is layered around the spring filter 31 by the force of the spring filter 31 pumping the liquid from the lower space 341 side to the upper space 342 side during filtration. As a result, the filtration aid 35 can function as a filter layer for removing insoluble matter.

Further, in the present method, the form of the filtration aid 35 is preferably in the form of powder, although it is not limited. By using a powdery filtration aid, it becomes easy to disperse it in a liquid, and it becomes possible to stably arrange the filter by the so-called precoating effect of laminating around the spring type filter 31. Here, the size of the powder of the filtration aid is not particularly limited, but is preferably in the range of, for example, an average particle size of 5 μm or more and 500 μm or less, and more preferably an average particle size of 10 μm or more and 100 μm or less. Is the range of.

The composition of the filtration aid 35 is not limited as long as it can exhibit the above functions, and may be, for example, an inorganic substance such as diatomaceous earth, activated charcoal, or zeolite, or polyethylene, polypropylene, or the like, and these. Polyolefins containing derivatives, polyvinyl chloride, polyvinyl acetate, polyethylene tetrafluoroethylene, etc. and halogenated polyolefins containing these derivatives, ethylene / vinyl alcohol, etc. and halogenated olefin copolymers containing these derivatives, cellulose, etc. and cellulose It may be an organic substance exemplified by a cellulose derivative having a skeleton.

In the present device 1, the filtration aid preferably includes a filtration aid container for accommodating the filtration aid. Although the filtration aid can be said to be a consumable item, it can be reused if it is washed, and the amount used as a consumable item is not so large, and it has the advantage that it requires a much smaller amount than the conventional filter. The method of actually using the filtration aid and its form will be clarified from the description below.

Further, in the present device 1, a reverse osmosis membrane device 4 is provided after the filtration device 3. The reverse osmosis membrane device 4 includes a reverse osmosis membrane, and by the action of the reverse osmosis membrane, impurities existing in the filtrate can be removed. That is, while physical filtration is performed by the filtration device in the first stage, it is possible to filter minute impurities or dissolved impurities existing in water by the reverse osmosis membrane device 4 in the second stage. In particular, when seawater is used as raw water, it is possible to remove organic substances and ions that are present in the seawater and cannot be completely removed by the filtration device 3. Here, the "reverse osmosis membrane" is also called an RO (Reverse Osmosis) membrane, and a large number of pores of about several nanometers are formed, and the fluid is purified by capturing organic substances and the like through these pores. Specifically, by applying pressure to the filtrate side mixed with impurities, it is possible for only water to permeate to the opposite side of the reverse osmosis membrane, and this water can be used for domestic water, etc. become able to. This reverse osmosis membrane device is indispensable when people eat it, such as drinking water, but when there is no problem with the mixing of ions, etc., which are not necessarily necessary for hygiene to the extent that it removes dirt from the toilet. Is optional.

Further, it is preferable that the reverse osmosis membrane device 4 is provided with a pump for carrying out the fluid at a high pressure in the reverse osmosis membrane device 4 as in the filtration device 3. The type of pump and the like are the same as those of the pump in the above filtration device.

As described above, according to the present device 1, it is possible to provide an emergency filtration device that can be more easily and stably stored for a long period of time and can reduce the number of consumables.

(Filtration method)
Here, the details of the filtration method (hereinafter referred to as “the present method”) will be described step by step. First, in this method, a case where the undiluted solution is pumped up from the water source S as a preparation will be described. In this method, the water source S is used from the viewpoint of facilitating the explanation, but it may be pumped up from the container containing the undiluted solution. The water source S may be, for example, a pond, a river, the sea, or the like, but is not limited thereto.

First, in this method, the filtration aid 35 is arranged around the spring type filter 31. Specifically, the filtration aid tank 374 is filled with relatively clean water, and the filtration aid 35 is dispersed therein to prepare a precoat liquid. Then, the pump 375 is driven to introduce the precoat liquid from the filtration aid tank 374 into the lower space 341, and the water discharged from the upper space 342 is returned to the filtration aid tank 374 again. By repeating this operation, the filtration aid is gradually accumulated around the spring-shaped filter 31 and formed as a filter layer.

Next, after sufficient precoating, the undiluted solution is pumped from the water source S via the pipe T1 using a pump, and while removing fallen leaves and hair by the hair collecting device 5, the lower space 341 of the spring type filter device 3 is used. The assembled stock solution is supplied and filtered. The filtered water is discharged from the filtrate pipe 37. Impurities have been removed from the filtrate discharged from the filtrate pipe 37, and impurities have been removed to such an extent that the filtrate can be used as domestic water.

As a result, minute impurities existing in the undiluted solution are trapped in the gaps of the filtration aid and cannot move to the internal space (upper space) 342 of the spring-like filter 31. As a result, the undiluted solution is filtered by the spring-shaped filter 31.

When the filtration is sufficiently completed, it can be terminated by stopping the driving of the pump. Filtration may be completed in a state in which the undiluted solution has disappeared, or in a state in which the pressure of the fluid in the housing becomes equal to or higher than a predetermined pressure. The pressure becomes higher than the predetermined pressure because the gaps between the filtration aids have begun to be filled with the captured impurities. Therefore, the primary filtration is terminated and the precoating with the filtration aids from which the impurities have been removed again is used. Is preferable. In this case, it is preferable to leave a small amount of the filtrate for the precoating to be performed in the next treatment.

Further, when this method is terminated, the filtration aid may remain around the spring-type filter 31. Therefore, it is preferable to reverse the flow of the pump and perform a step of removing the filtration aid adhering to the periphery of the spring type filter 31. Specifically, the valve 364 can be opened and discharged from the waste liquid branch pipe 363. By doing so, the spring-shaped filter 31 can be kept clean. Since the removed filtration aid is deposited under the lower space 341, it is possible to prevent a decrease in work efficiency due to the accumulation of the filtration aid by making the lower part of the housing openable.

Further, in this method, the filtrate filtered by the above-mentioned filtration device is further filtered by the reverse osmosis membrane device provided in the subsequent stage. Specifically, the filtrate is sent into the reverse osmosis membrane device using a pump or the like, and the purified water that has permeated the reverse osmosis membrane is taken out. It is possible to dispose of the discharged filtrate other than purified water as wastewater, but as mentioned above, if it is for domestic use other than drinking water and for which hygiene is not so important, use it as it is. You can also.

As described above, according to this apparatus, it is possible to remove insoluble matter having a predetermined size or more by combining the spring type filter 31 and the filtration aid 35 arranged around the spring type filter 31. Further, by using the reverse osmosis membrane device, it is possible to obtain water suitable for drinking by removing insoluble matter having a predetermined size or less, such as organic matter and ions. This device is extremely effective because it can replace seawater with purified water.

Further, since the present device 1 uses a generator that uses a cassette cylinder, unlike gasoline or the like, even if it remains in the device, the risk of deterioration and failure is reduced. Also, unlike batteries, it can be stored in large quantities and stably, and there is little risk of leakage. Furthermore, since a spring-type filter device is used, the time and effort required to replace the filter is extremely small compared to a general filter device. Even if it is needed, it is a filtration aid, and unlike a normal filter, it can be filtered in a very small amount, and the labor of replacing the filter is very small. That is, it is possible to provide an emergency filtration device that can be more easily stored for a long period of time and has fewer consumables.

The present invention has the possibility of being used in an industrial field as a filtration device. In particular, it is a simple system in the event of a disaster, and there is little concern that it will deteriorate even after long-term storage, making maintenance extremely simple.
