Urea removal method in pure water |
| abstract |
PROBLEM TO BE SOLVED: To remove a TOC component in pure water sufficiently by a conventional pure water production process because it contains urea as a main component and is nonionic. Although it can be removed by biological treatment or oxidant treatment, not only the apparatus becomes complicated, but also the number of contamination sources increases, making it difficult to obtain pure water with a sufficiently reduced TOC. A cation exchanger is formed in a desalting chamber of an electric desalting apparatus so that adsorption and elution by urea cationization can be performed. The cation exchanger is preferably a strongly acidic sulfonic acid group and the shape is fibrous. Urea in pure water can be reduced only by changing the ion exchanger filling structure of the desalting chamber of the conventional electric desalting apparatus. [Selection] Figure 1 |
