FIG. 3 is a view for explaining the configuration and operation of the water treatment apparatus 103 and the photographing apparatus 105 in the system according to the embodiment of the present invention. Referring to Fig. 3, there is shown a section of a water treatment apparatus 103 and a photographing apparatus 105 for optical coherence tomography.

According to one embodiment, the water treatment apparatus 103 may be provided so as to enable optical interference tomography of the filtration membrane. As shown in Fig. 3, the outer shape (e.g., housing) of the water treatment apparatus 103 may be formed in a spiral shape. At least one transparent window (hereinafter referred to as a transparent window 301) capable of transmitting light from the outside to the inner through-hole may be formed in the housing located at the outermost portion of the water treatment apparatus 103. As shown in FIG. 3, when a plurality of transparent windows 301 are formed, the transparent window 301 may be made of a material having excellent light transmittance.

The contamination degree of the filtration film provided inside the water treatment apparatus 103 can be measured through the transparent window 301. [ The transparent window 301 may be made of a material having high transmittance in order to reduce the light attenuation rate. The higher the transmittance, the less the error of the measured information and the higher the accuracy.

The transparent window 301 is provided on the outer circumferential surface of the water treatment apparatus 103 in the lateral direction (for example, in the circumferential direction) so that the filtration film contamination degree of the water treatment apparatus 103 can be measured in various directions along the flow of the raw water flowing into the water treatment apparatus 103. [ As shown in FIG. At the same time, the transparent window 301 may be formed at a predetermined interval in the longitudinal direction (e.g., the axial direction and the longitudinal direction) of the water treatment apparatus 103. In detail, each of the transparent windows formed on the outer circumferential surface of the water treatment apparatus 103 may be sequentially spaced apart in the horizontal and vertical directions. That is, as a result, the transparent window 301 may be formed in a spiral shape along the circumferential direction of the surface of the water treatment apparatus 103 formed in a cylindrical shape.

Although not shown in FIG. 3, the water treatment apparatus 103 can be rotated with respect to the central axis of the water treatment apparatus 103 by an external motor. A permeation-generating pipe of the water treatment apparatus 103 may be formed on the central axis of the water treatment apparatus 103.

The rotation direction of the water treatment apparatus 103 may be leftward or rightward with respect to the central axis. The rotation direction and rotation speed of the water treatment apparatus 103 can be determined according to predetermined control conditions such that the photographing apparatus 105 measures the degree of contamination of the filtration film through the transparent window 301 of the water treatment apparatus 103. [

Therefore, the light emitted from the photographing apparatus 105 while the water treatment apparatus 103 is rotated by the external motor is transmitted through the transparent window 301 formed in the water treatment apparatus 103 to the surface of the transparent window 301 vertically And the degree of contamination of the filtration membrane can be measured for all directions.

The pollution degree of the filtration film constituting the water treatment apparatus 103 according to various embodiments can be measured using the photographing apparatus 105 through the transparent window 301. [ Accordingly, in order to clean the water treatment apparatus, the entire seawater desalination process is stopped and the water treatment apparatus 103 is externally monitored without using a method of disassembling and disassembling the water treatment apparatus to quantify the contamination degree of the filtration membrane, It is possible to judge when the filtration membrane needs to be cleaned, and to clean or replace it.

In addition, when the operation of the water treatment apparatus 103 is canceled or disassembled, there has been a problem that recycling of the filtration membrane has been impossible. In addition, the time and cost required for measuring the degree of contamination of the filtration membrane can be reduced.

The photographing apparatus 105 may be installed outside the water treatment apparatus 103 so as to irradiate light in a direction perpendicular to the longitudinal direction of the water treatment apparatus 103. According to one embodiment, if the upper surface of the transparent window 301 has a curvature, the light emitted from the photographing apparatus 105 can enter in a direction perpendicular to the tangent of the outer peripheral surface of the water- When the upper surface of the transparent window 301 is a plane other than a curved surface, light may be incident in a direction perpendicular to the plane of the transparent window 301.

The rail 311 is installed so as to be spaced from the central axis of the water treatment apparatus 103 by a predetermined distance so as to be parallel to the water treatment apparatus 103 so that the photographing apparatus 301 can move in the lateral direction of the water treatment apparatus 301 . The photographing apparatus 105 is connected to the rail 311 and the photographing apparatus 105 installed on the rail 311 is disposed on the horizontal side of the water treatment apparatus 103 in accordance with the position of the transparent window 301 of the water treatment apparatus 103 to be measured Lt; / RTI >

3, the photographing apparatus 105 is described as being moved through the formed rail 311. However, the present invention is not limited to this, and the photographing apparatus 105 can be moved through various movable means such as a wheel or a bearing.

The photographing apparatus 105 can be moved in accordance with predetermined control conditions. For example, the imaging device 105 may be moved based on control conditions including at least some of the measurement location, the measurement time, or the number of measurement iterations.

The measurement position of the photographing apparatus 105 can be determined so that the camera is positioned at the center portion of the transparent window provided at the filtration film position of the water treatment apparatus / That is to say, the control device 101 can move the position of the photographing device 105 so that light emitted from the photographing device 105 can reach the center of the filter film provided in the water treatment device 103 in the lateral direction and the longitudinal direction have.

According to various embodiments, the rotation of the water treatment apparatus 103 as well as the photographing apparatus 105 can be controlled. The water treatment apparatus 103 can be rotated by a motor so that the light emitted from the photographing apparatus 105 can be incident in a direction perpendicular to the transparent window 301 of the water treatment apparatus 103.

Accordingly, the control unit 209 acquires image data in various directions with respect to the filtration membrane inside the water treatment apparatus 103, and can accurately monitor the contamination degree of the filtration membrane based on the image data measured in various directions. In addition, the control unit 209 can monitor the filtration film for a desired time through the transparent window 301 by controlling the rotation of the water treatment apparatus 103.

According to various embodiments, the system 10 may be formed including a plurality of water treatment devices. When the system 10 includes a plurality of water treatment devices, the water treatment device 103 and at least one other water treatment device may be connected in series or in parallel. In addition, the remaining water treatment devices other than the water treatment device 103 may be connected in series or in parallel. When a plurality of water treatment apparatuses are included in the system 10, a plurality of water treatment apparatuses can be controlled through the control apparatus 101. [

The control device 101 can generate the filtration membrane contaminants as visual data, for example, image or image data, based on the measured data on the filtration membrane. This makes it possible to intuitively identify the contaminants generated on the surface of the filtration membrane. In addition, since there is no process of stopping the operation of the water treatment apparatus in the water washing or chemical washing of the filtration membrane, it is possible to measure the contamination of the filtration membrane during the filtration membrane treatment process so that the filtration membrane contaminants The creation or removal process can be monitored and analyzed in real time.

In addition, the control device 101 can post-process the generated visual data to quantitatively analyze the contaminants generated on the surface of the filtration membrane. It is possible to calculate the optimum dosage of the chemicals to be used to chemically clean the filtration membrane depending on the amount of contaminants produced.

Thus, it is possible to calculate the optimum amount of drug input based on the quantified analysis data, without roughly determining the amount of drug input for filtration membrane cleaning through empirical analogy.

4 is a flowchart for explaining a method of controlling a filter membrane contamination of a water treatment apparatus in a system according to an embodiment of the present invention.

Referring to FIG. 4, in operation 401, the control unit 209 checks the filter film pollution degree measurement signal. For example, the control unit 209 confirms the filter film pollution degree measurement signal based on the filter film processing information stored (or set) in the memory 207. [ Here, the filtration film pollution degree measurement signal may be set to be generated at the specified time or within the specified time range. According to various embodiments, the filter film contamination level measurement signal may be a signal input through input 203.

In addition, when the filtering film pollution degree measurement is performed in real time, the control unit 209 can perform the operation 403 without performing the operation of the 401. [

In operation 403, the control unit 209 can perform the filtration film tomography through the photographing apparatus 105. The control unit 209 can control the photographing apparatus 105 to photograph the filtration film image data through at least one transparent window formed in the water treatment apparatus 103. [ At this time, the control unit 209 can control the photographing conditions such as the position shift or the photographing time of the photographing apparatus 105 based on the tomography information stored in the memory 207. [

The control unit 209 moves the photographing apparatus 105 to a predetermined position and moves the lens of the photographing apparatus 105 to the water treatment apparatus 103 so that the lens of the photographing apparatus 105 is positioned in the transparent window of the water treatment apparatus 103 103 can be rotated. Here, the control unit 209 can control the rotation of the water treatment apparatus 103 so that the light emitted from the photographing apparatus 105 reaches the transparent window vertically.

The control unit 209 controls the position of the photographing apparatus 105 or the rotation of the water treatment apparatus 103 and acquires tomographic image data of the filtration film through the plurality of transparent windows as described above. Here, the time taken by the photographing apparatus 105 to perform the filter film photographing through the transparent window may be the same as or different from the first photographing time.

More specifically, the position, time or frequency of photographing the filtration film through the photographing apparatus 9105 is stored in the memory 207 by the user's setting, for example, information inputted through the input unit 203 or stored in the memory 207 It depends on the information.

In operation 405, the control unit 209 determines the degree of contamination of the filtration membrane based on the acquired image data. According to one embodiment, the control unit 209 can quantify the filtering membrane pollution degree of the acquired image data and determine the pollution level of the filtration membrane. For example, the control unit 209 can determine the contamination degree of the filtration film by comparing the filtration film measurement information measured at a specific position of the filtration film with the filter film contamination information predetermined in the memory 207. [ Here, the filter film contamination information is related to the contamination of the filtration film, and the number of the contamination classified into a plurality of designated ranges in relation to the light transmittance of the filter film, the kind of the organic material, the thickness of the deposited organic material, the density of the accumulated organic material, Step < / RTI >

The filter film measurement information measured through the system 10 may include information related to at least some conditions of the filter film contamination information previously stored in the memory 207. [ For example, the filtration film measurement information may include at least some of the light transmittance of the filtration film, the type of the organic material, the thickness of the deposited organic material, the density of the deposited organic material, and the quantified value of the organic material.

The control unit 209 can determine the filtration membrane treatment method according to the determined degree of filtration membrane contamination based on the determined filtration membrane pollution degree and the filter membrane processing information previously stored in the memory 207. [ For example, the control unit 209 can determine at least one of the filtration membrane treatment methods, such as filtration membrane washing, filtration membrane chemical cleaning, and filtration membrane replacement, depending on the contamination degree of the filtration membrane.

In addition, the control unit 209 can determine the detailed operation according to the contamination degree of the filtration film in determining the filtration membrane treatment method. According to one embodiment, the filtering membrane processing information can be divided into various detailed operations for each of the filtration membrane water washing and the filtration membrane chemical washing according to the contamination degree of the filtration membrane.

For example, when the filtration membrane step is divided into five steps (for example, steps from 1 to 5, ascending order according to the degree of contamination) in accordance with the degree of contamination of the filtration membrane, the control unit 209 performs steps 2 and 3 And the detailed conditions such as the washing time and the water pressure can be determined differently in the washing of the water in the second and third steps.

Likewise, the control unit 209 determines the chemical treatment of the filtration membrane for the fourth and fifth steps according to the degree of contamination of the filtration membrane. In the chemical cleaning of the fourth and fifth steps, the type of the chemical, Amount and time of chemical treatment can be determined differently.
