如鐵銹和其他懸浮物等?；钚蕴窟^(guò)濾:活性炭是廣譜吸附劑, 可吸附氣體成分, 如水中的余氯等;吸附細(xì)菌和某些過(guò)渡金屬等。氯氣能損害反滲透膜, 因此應(yīng)除盡。反滲透膜過(guò)濾:可濾除95%以上的電解質(zhì)和大分子化合物, 包括膠體微粒和病du等。由于絕大多數(shù)離子的去除, 使離子交換柱的使用壽命有效延長(zhǎng)。紫外線(xiàn)消解:借助于短波(180～254nm)紫外線(xiàn)照射分解水中的不易被活性炭吸附的小有機(jī)化合物, 如甲醇，普陀區(qū)超純水哪個(gè)品牌好、乙醇等, 使其轉(zhuǎn)變成CO2 和水，普陀區(qū)超純水哪個(gè)品牌好，普陀區(qū)超純水哪個(gè)品牌好,以降低TOC
