氧化改性型纳滤膜元件性能的稳定性分析

Analysis of the performance stability of oxidation-modified nanofiltration components

分析了氧化改性型纳滤膜元件的透盐率、产水量、膜压降这三项性能指标在运行及清洗过程中的稳定性,进行了氧化改性型纳滤膜与标准反渗透膜的性能稳定性比较,证明了氧化改性型纳滤膜元件具有较好的稳定性,可以用于实际系统运行。

Three indexes of stability performances：salt permeability,water yield and membrane pressure drop,of oxidation-modified nanofiltration membrane components in running and cleaning processes have been analyzed. The performance stabilities of oxidation-modified nanofiltration membrane and standard reverse osmosis （RO） membrane have been compared. The results prove that oxidation-modified nano-filtration membrane components have better stability and can be used in actual system running.
