Advanced Chemical Methods Improve Film Processing and Control Pollution
Advanced chemical methods for wet processing of both negative and positive film have simultaneously produced improved film processing and pollution control. The methods include closed-loop fix desilvering with on-line ozone regeneration of the bleach, and ion-exchange color developer recycling. Silver recovery is further enhanced by electrolytic tailing and ion-exchange treatment of the wash waters. This article describes the actual results of two years' trouble-free operation of the advanced chemical methods in a film processing lab.
