高になる。The conventional filter shown in FIG. 4 has the following problems. That is, (1) When increasing the filtration area, the number of filters must be increased or a gravity type filter using a concrete water tank (a type of filter in which water flows downward due to its own weight) must be adopted. In the case of, however, in the case of, the maximum filtration area per unit is limited due to transportation restrictions, and if the filtration area is increased, the number of installed filters increases. When the number of installed filters is increased, the number of pipes and valves is increased, and the installation area of the entire filter is increased, resulting in high cost.

う問題があった。In the case of the above, the water flow rate is slow, and in order to compensate for this, it is necessary to increase the filtration area, and the size of the entire filter becomes large, and in this case also the cost becomes high. (2) If the filter is, for example, a pressurized sand filter that performs water treatment, it is necessary to perform backwashing once a day. Further, after backwashing, it is necessary to pass the rinse liquid at a rate of about 1 hour per filter unit in order to adjust the filtration layer (for example, sand particle layer) of the filtration unit 12 to the original state,
During that time, there was a problem that the original filtration treatment could not be performed, the filtration efficiency was lowered, and a large amount of rinse liquid was required.
