    • A method of increasing the purity of ultrapure water, in which any impurities contained in ultrapure water can be stably removed to a high degree within a limited space over a prolonged period of time; and an apparatus therefor. Ultrapure water introduced in ultrapure water purity increasing apparatus (10) passes through ion exchange resin layer (5) within inferior compartment (1a). In this stage, metal ions, etc. contained in the ultrapure water are removed by the ion exchange resin. Thereafter, the ultrapure water passes through perforated plate (4), flows into superior compartment (1b) and permeates ion exchange filter (6). In this stage, any metal ions, etc. remaining unremoved by the ion exchange resin layer (5) are removed. That is, metal ions are removed to a certain extent by the ion exchange resin, so that it is satisfactory for the ion exchange filter provided downstream thereof to remove an extremely small amount of metal ions. Consequently, reaching of the ion exchange filter to breakthrough within a short period of time can be prevented, thereby attaining increasing of the purity of ultrapure water over a prolonged period of time.
    • 提高超纯水的纯度的方法,其中超纯水中所含的任何杂质能够在有限的空间内在较长的时间内稳定地被去除; 及其装置。 在超纯水增加装置(10)中引入的超纯水通过下室(1a)内的离子交换树脂层(5)。 在这个阶段,通过离子交换树脂除去超纯水中所含的金属离子等。 此后,超纯水通过多孔板(4),流入上室(1b)并渗透离子交换过滤器(6)。 在这个阶段,除去离子交换树脂层(5)未被除去的任何金属离子等。 也就是说,金属离子在一定程度上被离子交换树脂除去,因此对于其下游提供的离子交换过滤器来除去极少量的金属离子是令人满意的。 因此,可以防止离子交换过滤器在短时间内到达,从而在长时间内提高超纯水的纯度。
