| Abstract |
Full scale demonstration of electrodialysis for closed loop treatment of brass plating cyanide rinse waters was conducted in the Keystone Lamp Manufacturing plant at Slatington, Pa. In treatment of actual rinse water, the system was only one-quarter as effective as anticipated. Numerous attempts to improve the efficiency of the installation were unsuccessful and the work was terminated. Laboratory studies indicated that the failure was caused by a reduction in the permselectivity of the anion membranes. It is believed that an insoluble zinc compound or zinc complex anion was retained on the membrane and reduced its permselectivity. To avoid future failures, the membranes need to be laboratory tested on actual waste waters before a full-scale demonstration. In this study the electrodialysis system was tested on sodium copper cyanide solutions, whereas the actual rinse waters contained sodium copper zinc cyanide. |
