The former has a drawback that the life of the ion exchange resin is short because the ion exchange capacity per unit amount of raw water is determined. The latter requires high-pressure pumps to pass water through the ultra-microfilter, and the piping structure must also be pressure-resistant, resulting in high cost and countermeasures against clogging. Moreover, both of them are intended to generate pure water, and therefore have a drawback that even when they are used for drinking or the like, appropriate mineral components which are useful are removed.
