纳滤纳滤 ( nf，nanofiltration)是一种介于反渗透和超滤之间的压力驱动膜分离过程，纳滤膜的孔径范围在几个纳米左右。与其他压力驱动型膜分离过程相比，出现较晚。它的出现可追溯到70年代末j.e. cadotte的ｎｓ-3 0 0膜的研究，之后，纳滤发展得很快，膜组器于80年代中期商品化。纳滤膜大多从反渗透膜衍化而来，如ca、cta膜、芳族聚酰胺复合膜和磺化聚醚砜膜等。但与反渗透相比，其操作压力更低，因此纳滤又被称作“低压反渗透”或“疏松反渗透”( loose ro )。纳滤分离作为一项新型的膜分离技术，技术原理近似机械筛分。但是纳滤膜本体带有电荷性。这是它在很低压力下仍具有较高脱盐性能和截留分子量为数百的膜也可脱除无机盐的重要原因。纳滤分离愈来愈广泛地应用于电子、食品和医药等行业，诸如超纯水制备、果汁高度浓缩、多肽和氨基酸分离、抗生素浓缩与纯化、乳清蛋白浓缩、纳滤膜-生化反应器耦合等实际分离过程中。与超滤或反渗透相比，纳滤过程对单价离子和分子量低于200的有机物截留较差，而对二价或多价离子及分子量介于200～500之间的有机物有较高脱除率, 基于这一特性，纳滤过程主要应用于水的软化、净化以及相对分子质量在百级的物质的分离、分级和浓缩（如染料、抗生素、多肽、多醣等化工和生物工程产物的分级和浓缩）、脱色和去异味等。主要用于饮用水中脱除ca、mg离子等硬度成分、三卤甲烷中间体、异味、色度、农药、合成洗涤剂，可溶性有机物，及蒸发残留物质。随着对环境保护和资源综合利用认识的不断提高，人们希望在治理废水的同时实现有价物质的回收，比如：大豆乳清废液中含有1%左右的低聚糖和少量的盐，亚硫酸盐法制备化纤浆和造纸浆过程出现的亚硫酸钙废液中含有2%～2.5%的六碳糖和五碳糖，制糖工业中出现的废糖蜜中含有少量的盐等等。
