Abstract An important new membrane has been developed for the reverse osmosis treatment of both highly alkaline and acidic (non-oxidizing) metal finishing rinse waters. This membrane designated NS-1, and originally developed for seawater desalination, consists of the following: a microporous support film (polysulfone) coated with polyethylenimine which is cross-linked with tolylene 2,4-diisocyanate. Simulated alkaline copper and zinc cyanide plating rinses at pH's of 11.8 and 12.9 were treated by NS-1 membranes during 500- and 340-hour tests without deterioration of reverse osmosis properties. Water fluxes above 10 gallons per square foot (of membrane) per day (gfd) were observed with cyanide rejections between 95 and 99 percent. The NS-1 membrane also treated simulated copper sulfate rinse waters effectively at pH 0.5 during 550-hour tests without deterioration of reverse osmosis properties (fluxes above 10 gfd with 99.8 percent rejection of copper). Preliminary engineering considerations indicated the feasibility of applying the NS-1 membrane to reverse osmosis treatment and recycle of nickel and zinc cyanide electroplating rinse waters.
