It includes a sample inspection member 575 having a turbidimeter, a differential pressure gauge, and the like. The monitoring member 570 may sequentially inspect each fiber filtration member 560.

As shown in FIG. 8, first, when there is a filtering signal (S100), 1 is added to an N value that was 0 during initial driving while the newly calculated N value does not exceed the maximum value M (S110).

Then, it is determined whether it is backwashing (S120), and if it is backwashing, the backwashing process (S230) is performed. The valve 572 is opened (S140).

Thereafter, the semen pump 574 is started (S150), delayed for a predetermined time, for example, 10 minutes (S160), and then turbidity is measured with a turbidimeter (S170) to determine whether there is a measured turbidity within the tolerance range. If it is determined (S180), if the tolerance is within the range of the differential pressure gauge measurement step (S200), and if the tolerance is exceeded, an alarm sounds (S190).

Then, it is determined whether there is a differential pressure measured within the tolerance range in the differential pressure gauge measurement step (S200) (S210), if it is within the tolerance range, go to the initial step (S100) to repeat the measurement, and if the tolerance exceeds the alarm range Ringing (S220).

By the above configuration, the samples are sequentially measured in the plurality of fiber filtration member 560 to be monitored in real time by the monitoring member 570.
