The water flows into the water intake port 25 of No. 5, and after being filtered by the filter layers 23 and 21 of the preliminary filtration tank 15, it flows into the outlet chamber 9.
and is discharged through the outlet pipe 5b. According to this, even if filtration blockage occurs in the filtration tank 5, the preliminary filtration tank 15
The operation of the filtration device continues for a predetermined period of time until filtration blockage occurs.

程度にすることが望ましい。The predetermined time period until filtration clogging occurs in the preliminary filtration tank 15 largely depends on the volume of the preliminary filtration tank 15. However, if the volume of the preliminary filtration tank 15 is too large in order to lengthen the predetermined time, the entire filtration device will become larger. Its volume is 10 to 30% of the volume of the filtration tank 5
It is desirable to keep it at a certain level.
