【摘要】 本研究测定了低压反渗透复合膜ＮＴＲ—７２９ＨＦ在含盐量２～３０ｍｍｏｌ／Ｌ体系中的脱盐性能。结果表明：该膜水通量为１．５６ｍ３／ｍ２．ｄ，是ＣＡ膜的５倍；脱盐率主要受阴离子控制；结垢成分优先除去，硬度和除去率分别大于９８％、８８％和８２％。更多还原

【Abstract】 Desalination performance of low pressure reverse osmosis membrane NTR-729HF was determined when tested in salt concentration 2～30 mmol/L.The results showed that water flux ofNTR-729HF is 1.56 m3/m2·d,five times as much as that of CA,and that salt rejection isdominated primarily by negative ions.Scaling composition is selectively rejected. Rejections of,hardness and HCO are greater than 98%, 88% and 82% respectively.更多还原
