[0118] Next, a first embodiment of the present invention will be described. The UFB-containing liquid generating facility in the embodiment has the same basic structure as described above, and UFB is generated in the supplied gas solution by a UFB generating unit using the T-UFB method using a heater. As described above, in the T-UFB method, bubbles having a diameter larger than that of UFB (micro-sized bubbles (hereinafter referred to as MB) and millimeter-sized bubbles) are not generated, and only UFBs are generated. Therefore, it can be said that the T-UFB method is a very effective method for producing UFB when producing a high-concentration UFB-containing liquid. However, conventional UFB-containing liquid generating equipment using a UFB generating unit employing a T-UFB generating method has a problem that, in the case where MB is contained in the liquid supplied to a portion near the UFB generating unit, MB hinders UFB , and in some cases UFBs are generated less effic...

[0146] Next, a second embodiment of the present invention will be described. In the first embodiment, an example in which the UFB generation efficiency is improved by providing the MB inflow blocking unit before the UFB generation heater was explained. Meanwhile, in this embodiment, an example in which the circulation pump 409 is used to be able to generate a UFB-containing liquid having a higher concentration is explained.
[0147] Figure 16 The device configuration in this embodiment is shown. Figure 16 The liquid input unit 401, liquid input tank 402, gas dissolution unit 403, MB inflow obstruction unit 408, UFB generation unit 404, UFB-containing liquid output tank 405, UFB-containing liquid output unit 406, and valves V401 and V405 shown in Figure 14 211 to 218 shown in and V201 and V205 are the same. Therefore, its detailed description is omitted.

[0179] Next, refer to Figure 23 A third embodiment of the present invention will be described. In this embodiment, the apparatus has a configuration in which an MB discharge unit 1110 is connected to an MB inflow blocking unit 1108 , and MB accumulated in the MB inflow blocking unit 1108 is discharged from the MB discharge unit 1110 to the outside. Note that other configurations are the same as those in the first modified example of the second embodiment. specifically, Figure 23 The liquid input unit 1101, liquid input tank 1102, gas dissolution unit 1103, UFB generation unit 1104, UFB-containing liquid output tank 1105, UFB-containing liquid output unit 1106 and circulation pump 1109 shown in Figure 17 501 to 506 shown are the same as 509 . Therefore, the description of the configuration of the flow passage formed by these components is omitted, and the configuration and functions peculiar to this embodiment are mainly described.
