Method and apparatus for preventing scale from precipitating in producing deionized water |
| 摘要 |
A method for preventing scale from precipitating and an apparatus for producing deionized water are disclosed. The acidic water produced by electrolysis in the electrolysis unit (30) is introduced into a concentrating compartment (19) in the continuous deionization unit (10). The pH of the concentrated water in the concentrating compartment decreases, thereby preventing scale from precipitating.
