State diagram.

The ultrafiltration module 400 is an ultrafiltration tank 410 and a central filtration tank 410 having a central entry port 411 on one side as shown in FIGS. 2 and 3, according to an embodiment of the present invention, and an upper portion of the ultrafiltration tank 410. The upper header tank 420 is disposed in the upper header port 421 is formed on one side, and the lower header tank 430 is disposed in the lower portion of the ultrafiltration water tank 410 and the lower outlet port 431 is formed on one side And, both ends may be configured to include a cylindrical ultrafiltration membrane 440 mounted inside the ultrafiltration tank 410 so as to communicate with the upper header tank 420 and the lower header tank 430, respectively.

The ultrafiltration tank 410 may be formed in a hollow cylindrical or polygonal column shape so that an accommodation space is formed therein, and the upper header tank 420 and the lower header tank 430 communicate with the ultrafiltration tank 410, respectively. The upper header tank 420 and the lower header tank 430 communicate with each other through the ultrafiltration membrane 440. The ultrafiltration membrane 440 is a kind of membrane for filtering fine particles, and is preferably formed in a hollow cylindrical shape having a space therein, and fluid flows from the inside to the outside of the ultrafiltration membrane 440. Or fine particles contained in the fluid in the process of flowing from the outside to the inside (external pressure type).

That is, the ultrafiltration module 400 is subjected to various filtering processes through three entry and exit ports 411, 421, and 431 as shown in FIG. 2. That is, as illustrated in FIG. 2A, the filtering process may be performed externally, or as illustrated in FIG. 2B, the filtering process may be performed. In more detail, as shown in (a) of FIG. 2, the upper entry and exit port 421 may be applied as the inlet, and the central entry and exit port 411 may be applied as the outlet. Accordingly, the primary treated water may be the upper entry and exit port. 421 flows into the inner space of the ultrafiltration membrane 440, passes through the sidewall of the ultrafiltration membrane 440, and flows to the outside of the ultrafiltration membrane 440, and is then ultrafiltration through the central entry port 411. It is discharged to the outside of the water tank (410). In addition, as shown in (b) of FIG. 2, the lower entry / exit port 431 may be applied as the inlet and the central entry / exit port 411 may be applied as the outlet. In this case, in the same manner as in FIG. The primary treatment water flows into the lower entry / exit port 431, passes through the sidewall of the ultrafiltration membrane 440 from the inside to the outside, and is discharged to the central entry / exit port 411. Therefore, the structure of the ultrafiltration module 400 shown in (a) and (b) of FIG. 2 is composed of a pressure-resistant filtering process that passes through the sidewall of the ultrafiltration membrane 440 from the inside to the outward direction.

Of course, in contrast, the central entry and exit port 411 may be applied as an inlet and the upper entry and exit port 421 may be applied as an outlet. Accordingly, the primary treated water may be introduced into the central entry and exit port 411 and thus the ultrafiltration membrane 440 may be formed. It may pass through the side wall and flow from the outside of the ultrafiltration membrane to the inside, and then may be discharged to the outside of the ultrafiltration water tank 410 through the upper entry port 421. In addition, the central inlet / outlet port 411 may be applied as an inlet and the lower inlet / outlet port 431 may be applied as an outlet. In this case, the first treatment water may be introduced into the central inlet / outlet 411 to externally close the sidewall of the ultrafiltration membrane 440. Pass through the inside and may be discharged to the lower entry and exit port 431. Therefore, in this case, all of the structures of the ultrafiltration module 400 are configured by an external pressure filtering process that passes through the sidewall of the ultrafiltration membrane 440 from the outside to the inward direction.

Ultrafiltration module 400 according to an embodiment of the present invention are all configured in a pressure-resistant filtering method, the central entry and exit port 411 is always in the process of filtering the primary treated water as shown in FIG. It becomes an outlet and the upper entry-out port 421 and the lower entry-out port 431 are comprised so that it may become an inlet alternately every predetermined time interval. According to this configuration, since the ultrafiltration module 400 changes the flow of water in the opposite direction at regular intervals, an automatic cleaning effect occurs, thereby maintaining better filtering performance.

On the other hand, the ultrafiltration module 400 is washed in a backwash manner as described above, in this case, as shown in FIG. That is, in the case of backwashing, the central inlet / outlet port 411 is a backwashing water inlet through which backwashing water flows, and the upper inlet / outlet port 421 and the lower inlet / outlet port 431 are backwashing water outlets through which backwashing water flows out. In addition, the upper entry / exit port 421 and the lower entry / exit port 431 are applied to the backwash water outlet as opposed to the aforementioned filtering process.

That is, when the lower entry and exit port 421 is applied to the inlet and the central entry and exit port 411 is applied to the outlet in the filtering flow, as shown in (a) of FIG. 2, FIG. As shown in FIG. 3, the central inlet and outlet ports 411 are applied to the backwash water inlet and the upper inlet and outlet port 431 is applied to the backwash water outlet. In addition, when the upper entry and exit port 421 is applied as the inlet and the central entry and exit port 411 as the outlet in the filtering flow, as shown in (b) of FIG. As shown in FIG. 3, the central inlet and outlet port 411 is applied to the backwash water inlet and the lower inlet and outlet port 431 is applied to the backwash water outlet. According to this backwashing flow, the flow of the effluent can proceed more smoothly.

The ultrafiltration module 400 configured as described above may be controlled by the control unit 20 to repeatedly circulate the first filtration process and the second filtration process at predetermined time intervals according to an embodiment of the present invention.

As shown in (a) of FIG. 4, the first filtration process includes a first filtering process in which the primary treated water flows into the lower entry / exit port 431 and exits to the central entry / exit port 411, and after the first filtering process 1 The first washing process in which the primary treated water flows into the lower entry / exit port 431 and flows out to the upper entry / exit port 421, and after the first washing process, the backwash water flows into the central entry / exit port 411, and thus the upper entry / exit port 421. It comprises the first backwash process to flow out. As shown in (b) of FIG. 4, the second filtration process includes a second filtering process in which the primary treated water flows into the upper entry and exit port 421 and flows out to the central entry and exit port 411, and then after the second filtering process. The second washing process in which the primary treated water flows into the upper entry / exit port 421 and flows out to the lower entry / exit port 431, and after the second washing process, the backwash water flows into the central entry / exit port 411, and thus the lower entry / exit port 431 It comprises the first backwash process to flow out.

In this case, it is preferable that the first filtration process and the second filtration process are configured to be performed for the same time, and the first filtering process and the second filtering process take up the longest time in each filtration process. For example, when each filtration process is performed at an interval of 1 hour, the first filtering process and the second filtering process are 57 minutes, the first washing process and the second washing process are respectively 2 minutes, the first back washing process, The second backwashing process may be configured to proceed for 1 minute each.

Here, a separate washing process is added between each filtering process and the backwashing process, which firstly washes foreign matter accumulated in the inner ultrafiltration membrane 440 by switching the flow of water to the ultrafiltration module before the backwashing process. To do that. The washing water discharged through this washing process is configured to be discharged in the same manner as the discharge path of the backwash water.

Through this process, the ultrafiltration module 400 may perform the water treatment function more smoothly, and may maintain a better operating state.
