Various types of water, such as river water, are applied. In the present invention, a trial calculation was especially performed for sewage treated water having a salt concentration of about 2000 mg / l. According to trial calculations, the concentrated ice 13a in the ice concentrator 13
Even if water is not washed with the ice washing water 15a, 15b, the quality of pure water or the clean water 23a in the clean water storage tank 23 is about 400 mg / l of salt concentration, and the water quality is the average salt concentration of clean water in Japan. Although the concentration was higher than 200 mg / l, it was found that pure water 23a having extremely high purity was obtained by repeating the washing cycle of the concentrated ice 13a. That is, the salt quality of the pure water or the clean water 23a becomes 200 mg / l by the first washing cycle,
The third washing cycle brought the salt concentration to 100 mg / l and the third washing cycle brought the salt concentration to 50 mg / l.
