In the test range, Na2SO4 rejection of NFⅠwas higher than 99%, permeate conductivity was lower than 170μs·cm-1; Na2SO4 rejection of NFⅡwas higher than 98%, permeate conductivity was lower than 370μs·cm-1, so the permeate quality can meet different requirement.
在试验范围内,NFⅠ膜对硫酸钠的截留率在99%以上,产水电导率小于170μs·cm-1;NFⅡ膜对硫酸钠的截留率大于98%,产水电导率小于370μs·cm-1 ,可满足不同用水要求。
