    膜分离法是利用高分子所具有的选择性来进行物质分离的技术,包括电渗析、反渗透、膜萃取、超过滤等。用电渗析法处理电镀产业废水,处理后废水组成不变,有利于回槽使用。含Cu2+、Ni2+、Zn2+Cr6+等金属离子废水都适宜用电渗析处理,已有成套设备。反渗透法已大规模用于镀Zn、Ni、Cr漂洗水和混合重金属废水处理。采用反渗透法处理电镀废水,已处理水可以回用,实现闭路循环。液膜法治理电镀废水的研究报道很多,有些领域液膜法已由基础理论研究进进到初步产业应用阶段,如我国和奥地利均用乳状液膜技术处理含Zn废水,此外也应用于镀Au废液处理中。膜萃取技术是一种高效、无二次污染的分离技术,该项技术在金属萃取方面有很大进展。
