That is, the concentrated algae water flow rate adjustment device 40 can be configured by the concentrated algae water flow meter 43, the flow rate adjustment valve 42, the concentrated algae water control device 44, and the like.
- the structure of the concentrated algae water flow control apparatus 40 is not restricted above.
- the flow rate may be adjusted by changing the height at which the concentrated algae water 13 is conveyed, or by preparing a plurality of paths having different flow path resistances and selecting an appropriate path to flow.
- other known flow rate adjusting means can be used.
- the filtered water discharge port 8 is disposed above the filter 3 of the concentration container 1 and discharges the filtered water 12 that has passed through the filter 3 from the concentration container 1.
- the filter 3 is disposed at a position that is too high, the weight of the filtered water 12 on the filter 3 increases, and the vibration device 5 does not easily vibrate the filter 3 in the out-of-plane direction. Therefore, for example, the filter 3 is disposed at a position 1 to 5 mm higher, preferably 1 to 2 mm higher.
- a tube is connected to the filtrate outlet 8 and the filtrate 12 is returned to the culture pond (not shown).
- the filtered water 12 may be used for other purposes or discarded.

- a filtered water drainage flow meter 37 that measures the flow rate of the filtered water 12 flowing out from the filtered water discharge port 8 is provided, and the flow rate of the filtered water 12 is transmitted to the concentrated algae water control device 44. Therefore, the concentrated algae water control device 44 can calculate the total flow rate of the concentrated algae water 13 and filtered water 12 flowing out from the concentration container 1.
- the algae water 10 is taken into the algae water supply container 18 from the culture pond. Then, the algae water 10 is taken into the concentration container 1 from the algae water supply container 18. In the concentration container 1, the algae water is taken in until the filter 3 is immersed in the algae water 10.
- the algae water concentration system 100 is operated and then stopped, if the filter 3 is at a position higher than the liquid level of the filtered water 12, the filter 3 is exposed to air. Then, surface tension is generated in the algae water 10 remaining in the opening of the filter 3. Therefore, the algal water 10 remaining in the opening closes the opening, and the air that has entered between the filter 3 and the concentrated algal water 13 or the algal water 10 below the filter 3 cannot be removed.
- the concentrated algae water 13 or the algae water 10 cannot contact the filter 3. Therefore, the concentration operation of the algae water cannot be resumed. That is, it is preferable that the filter 3 is always immersed in the algae water 10 or the filtered water 12. Therefore, the filtered water discharge port 8 is disposed at a position higher than the highest position of the vibrating filter 3.

- the filter 3 vibrates, it is possible to prevent the algae from adhering to the filter 3, but when the vibration is stopped, the algae adheres and the opening is blocked. This is the operation preparation stage.
- the liquid level 22 of the algae water 10 in the algae water supply container 18 is made higher than the height of the filter 3 by a predetermined water level difference 23. Since the height of the filter 3 is substantially determined, the liquid level 22 of the algae water 10 in the algae water supply container 18 may be adjusted as described with reference to FIG. If the water level difference 23 is too large, the force by which the algal water 10 pushes the filter 3 (including the filter frame 4 and the like) upward increases. Then, the force is transmitted from the coupling mechanism 6 to the vibration device 5, and a large driving force is required to vibrate the vibration device 5. In some cases, the vibration device 5 does not operate.
- the predetermined water level difference 23 varies depending on conditions such as the type of algae and the size of the opening of the filter 3, but is often about 100 mm to 300 mm.

- the filtered water 12 flowing above the filter 3 is discharged out of the concentration container 1 from the filtered water discharge port 8.
- the flow rate is measured by the filtered water drainage flow meter 37 and transmitted to the concentrated algae water control device 44.
- the algae 15 having a size larger than the opening of the filter 3 in the algae water 10 reaching the filter 3 cannot pass through the opening and remains in the space below the filter 3. At that time, even if the filter 3 is reached, the filter 3 vibrates out of the plane and is reflected by the filter 3 and does not adhere to the filter 3. Therefore, the opening is not clogged. That is, it is not necessary to clean the filter 3.
- the concentration rate in the concentration container 1 is calculated from the flow rate of the algae water 10 entering the concentration container 1, the flow rate of the filtered water 12 discharged from the concentration container 1, and the flow rate of the concentrated algae water 13 flowing out of the concentration container 1. can do.

Furthermore, from the flow rate of the algae water 10 flowing into the concentration container 1 and the flow rates of the filtered water 12 and the concentrated algae water 13 flowing out from the concentration container 1, it can be confirmed whether or not a leak has occurred in the algae water concentration system 100.
- Concentrated algae water 13 in the space below the filter 3 of the concentration container 1 is agitated by the flow of the algae water 10 flowing from the concentration container algae water intake 7, and the degree of concentration becomes uniform.
