反渗透 又称逆渗透,一种以压力差为推动力,从溶液中分离出溶剂的膜分离操作。对膜一侧的料液施加压力,当压力超过它的渗透压时,溶剂会逆着自然渗透的方向作反向渗透。从而在膜的低压侧得到透过的溶剂,即渗透液;高压侧得到浓缩的溶液,即浓缩液。若用反渗?复砗K谀さ牡脱共嗟玫降诟哐共嗟玫铰彼? 反渗透时,溶剂的渗透速率即液流能量N为: N=Kh(Δp-Δπ) 式中Kh为水力渗透系数,它随温度升高稍有增大;Δp为膜两侧的静压差;Δπ为膜两侧溶液的渗透压差。稀溶液的渗透压π为: π=iCRT 式中i为溶质分子电离生成的离子数;C为溶质的摩尔浓度;R为摩尔气体常数;T为绝对温度。 反渗透通常使用非对称膜和复合膜。反渗透所用的设备,主要是中空纤维式或卷式的膜分离设备。 反渗透膜能截留水中的各种无机离子、胶体物质和大分子溶质,从而取得净制的水。也可用于大分子有机物溶液的预浓缩。由于反渗透过程简单,能耗低,近20年来得到迅速发展。现已大规模应用于海水和苦咸水(见卤水)淡化、锅炉用水软化和废水处理,并与离子交换结合制取高纯水,目前其应用范围正在扩大,已开始用于乳品、果汁的浓缩以及生化和生物制剂的分离和浓缩方面。
