济南净水器应定期更换滤芯
2014-9-7 11:31:26

从净化技术方面看,现在市场上销售的净水器差别不大。第一级的粗滤,基本都是采用PP棉或PP棉加活性炭,主要作用是过滤水中的杂质、泥沙和悬浮物;之后是活性炭,主要去除和分解水中的有机有害物和异色、异味;最后是超滤膜或反渗透膜,其功能是过滤细菌、钙镁离子、重金属等。某品牌净水器导购员姚女士介绍,净水器的功能,就是由这几种滤芯的不同搭配来决定的,主要分为超滤膜净水器和反渗透净水器。
From purification technology perspective, the difference is now water purifier on the market is unlikely. The first stage of the coarse filter, basically using PP cotton or PP cotton and activated carbon, the main role is to filter impurities in the water, sediment and suspended solids; followed by activated carbon, the main water removal and decomposition of organic harmful substances and Harmonia, odor; finally ultrafiltration or reverse osmosis membranes, and its function is to filter bacteria, calcium and magnesium ions, heavy metals. A certain brand of water purifier Purchasing Guide Ms. Yao introduced water purifiers feature is by a different mix of these types of filters to decide, mainly divided into ultrafiltration and reverse osmosis water purifier water purifier.
净水器对自来水进行二次加工后,产出的水肯定比自来水要干净。但净水器在使用一段时间后管道、设备会造成二次污染,这是不可避免的。公众健康饮用水研究所曾对4款不同过滤类型的主流家用净水器进行过长达20天的综合性能测试。结果发现,随着净水器使用时间的增加,净化水中微生物(细菌总数)的含量也大幅增加。因此,定期更换净水器滤芯非常必要,否则净水器则可能变成“污水器”。通常情况下,PP棉滤芯寿命为1~2个月、活性炭滤芯使用周期为3~6个月、超滤(UF)滤芯寿命为24个月、反渗透(RO)滤芯寿命为36个月。
After tap water purifier for secondary processing, output is definitely better than tap water to clean. But water purifier in the pipeline for some time after use, the device will cause secondary pollution, which is inevitable. Public Health Institute filtered drinking water had 4 different types of home water purifier mainstream carried up to 20 days of comprehensive performance testing.It was found that with the increase of water purifiers use of time, purified water microorganisms (total bacteria) levels also increased significantly. Therefore, periodic replacement of water purifier filter is necessary, otherwise the water purifier may become "water filter." Under normal circumstances, PP cotton filter life of 1 to 2 months, the carbon filter life cycle of 3 to 6 months, ultrafiltration (UF) filter life for 24 months, reverse osmosis (RO) filter life for 36 months.
