For two years from 1993 to 1995, tap water was continuously passed under the following conditions, and a test was performed to confirm changes in the pipe inner wall and water quality. In addition, a test for confirming changes in the pipe inner wall and water quality under the same conditions was also performed on a device without any water treatment device. <Conditions> Magnet laminated body: Use the type shown in Fig. 3 Water way Water: Room temperature Piping material: Galvanized steel pipe Piping pipe diameter: 100A to 20A As a result, pipes without water treatment equipment after 2 years have passed Red rust was generated on the inner diameter, and the generation of red water was confirmed.On the other hand, in the case of the apparatus equipped with the water treatment apparatus of the present embodiment, no red rust was generated on the inner wall of the pipe, and the generation of red water was not observed. Not confirmed.

A magnetic processing apparatus C shown in FIG. 13 having a magnetic processing space 12 and a high-frequency processing space 9 is disposed on the secondary side of the water storage tank. Magnetic processing devices C and C shown in FIG. 2 that perform only processing
For the example with
A test was conducted to confirm changes in the inner wall of the pipe and the water quality by continuously passing tap water under the following conditions over the years. In addition, a test for confirming changes in the pipe inner wall and water quality under the same conditions was also performed on a device without any water treatment device. <Conditions> Magnet laminated body: Use the type shown in Fig. 3 Water way Water: Room temperature Piping material: Galvanized steel pipe Piping pipe diameter: 100A to 20A As a result, after 3 years, no piping is provided with a water treatment device Red rust was generated on the inner wall, and the generation of red water was confirmed. On the other hand, in the case of the apparatus equipped with the water treatment apparatus of the present embodiment, no red rust was generated on the inner wall of the pipe and the generation of red water was observed. Was also not confirmed.

Further, an embodiment in which an ultrasonic processing space was provided in place of the high-frequency processing space was tested under the same conditions as the above test, but the same result was confirmed.

[0084]

According to the present invention, the water flowing on the primary side and the secondary side of the water storage tank is magnetically treated, and the water processed on the primary side and the secondary side is introduced into the water storage tank. The magnetic treatment is further performed in the bypass that circulates the water, so that the water sent to the pipes is efficiently and highly magnetically treated, and the treated water is circulated through the pipes. In addition to the apparatus, a water treatment apparatus has been provided which is more effective in removing red rust and the like in pipes, preventing the generation of red rust and preventing the deposition of impurities.

When at least the magnetic treatment device on the secondary side of the water storage tank of the above-mentioned magnetic treatment device is configured to magnetically treat the inflowing water and to perform high-frequency treatment or ultrasonic treatment, compared with the conventional one. Thus, it is possible to provide water with higher treatment efficiency.
