In the purifying apparatus 10 of the illustrated example, water discharged from the pool (hereinafter, water means pool water) is introduced into the purifying apparatus 10 through an inlet 30 connected to the pool.

The introduced water is sucked by the circulation pump 26a or 26b, or is dropped from the pool so that the pre-filter 16
It is introduced into a and 16b, and removes large impurities such as hair and dust.

Next, the water flows into the circulation pump 26a or 26b, is discharged, and flows into the ceramic filter tank 14. The ceramic filter tank 14 has a large number of cylindrical ceramic filters inside, and water is filtered by passing through a wall from the outside of the ceramic filter to remove fine impurities such as oil discharged from the human body. The ceramic filter has a three-dimensionally extremely fine filtration space that is preferable for filtering pools, especially hot water pools, and it is also possible to use organic substances such as oil released from the human body that could not be filtered by conventional filters. It is possible to filter.

The water discharged from the ceramic filter tank 14
It flows into a and 18b and is sterilized. Sterilizers 18a and 18b
Is to sterilize water by applying ozone and ultraviolet rays, and an ultraviolet lamp and an ozone lamp are arranged inside,
By introducing air from the outside, the water is sufficiently bubbled, stirred, and ozone is generated. The ozone and ultraviolet rays sterilize the water.

The water that has been sterilized then flows into the adsorption purification tank 20. The adsorption septic tank 20 is made of activated carbon and zeolite,
Bacteria and the like decomposed by the sterilization tanks 18a and 18b are adsorbed, and these contained in water are removed.

The water discharged from the adsorption purification tank 20 is heated to a predetermined temperature by the heat exchanger 24, and flows into the pool again through the discharge port 32.

The filter aid tank 22 is internally divided into two tanks, each of which is filled with a powdery filter aid such as diatomaceous earth and a mixture of fibrous filter aid such as pulp fiber and water as a filter aid. .

As mentioned above, the ceramic filter has very fine pores three-dimensionally, and if it is applied to purified water as it is, it will be clogged immediately, and in extreme cases, an expensive ceramic filter cannot be used. It will be possible. Therefore, it is preferable that the filter aid layer is formed on the outer cylindrical portion of the cylindrical ceramic filter to prevent the ceramic filter from being clogged and facilitate the backwashing cleaning that is regularly performed. Any known filter aid can be applied, and the method for forming the filter aid layer on the ceramic filter may be a known method.

The hot water storage tank 28 stores water for supplementing the water in the pool and showers, sterilization tanks, eye washers, etc., which accompany the pool.

Further, it is preferable that the purification device 10 in the illustrated example has a backwash cleaning device for backwashing and cleaning the ceramic filter.
The method of backwashing and cleaning is not particularly limited, but preferably, the method of cleaning the ceramic filter disclosed in Japanese Patent Application No. 2-35029 by the present applicant is applied.

In the purification device 10 of the illustrated example, each of these devices (tank)
Is arranged and fixed at a predetermined position on the base 12, but here, as described above, the base 12 is a base piece (hereinafter, simply Called the base) 12
It is configured so that it can be divided into two parts, a and a base piece (hereinafter, simply referred to as a base) 12b.

That is, in the purification device 10 of the illustrated example, the flanges 34, 36, which are the internal connecting means of the internal pipes that connect the devices.
By removing 38, 40 and 42 and dividing the bases 12a and 12b, it is possible to divide the bases 12a and 12b into two along the alternate long and short dash line in FIG.

For example, if the purification device 10 has a size of 5500 mm in the longitudinal direction and 3600 mm in the lateral direction, the size can be set to 5500 x 1800 mm, and it can be transported in a small truck, which was not possible with conventional purification devices. Becomes

Therefore, by applying the purification device 10 of the present invention,
After assembling the purification device 10 once in the manufacturing plant, it was divided into two by dividing the bases 12a and 12b, transported and placed on the installation site, and then the bases 12a and 12b were combined and removed. The assembly of the purifying device 10 can be completed only by connecting the flanges (positioning of the connection portion is extremely easy because it has been completed when assembled in the manufacturing factory first).
