Description:
A program to demonstrate the feasibility of metal salt recovery and pollution control by ion selective diffusion, also known as Donnan dialysis was conducted on a Watts type nickel plating line. The objective of the program was to demonstrate the tubular membrane configuration and to determine the suitable operating conditions for the equipment. Several modules, consisting of tubular cation exchange membrane material mounted within a shell, were used to remove nickel ion from plating rinsewater with accompanying replacement of the nickel by hydrogen ion. Recovery rates were determined at various operating conditions.
