几种膜组件在管道直饮水处理系统中应用对比

Study of the use of membrane filtration in drinking water treatment

膜处理是管道直饮水处理工艺的核心,介绍了微滤膜(MF)、超滤膜(UF)、纳滤膜(NF)、反渗透膜(RO)四种膜在管道直饮水处理系统中应用的对比,内容包括基本性能、去除杂质能力、工作压力以及出水电阻率等。结果显示,相比于其他三种膜,纳滤膜(NF)在直饮水处理工艺应用更具优势。

Membrane separation process is the most important process in drinking water treatment.Article illustrates the use of microfiltration membrane(MF),ultrafiltration membrane (UF),nanofiltration membrane(NF)and reverse osmosis membrane(RO)in drinking water treatment.At the same time,the basic properties,the abilities of impurity removal,the operation pressures and the resistances of produced water of those four membranes and so on are contrasted. At last,nanofiltration membrane(NF)is recommended as the best one.
