Concentrations of silver-contaminated wastewater must be maintained below local limits established by each sewering agency. Ways to Manage Silver • Eliminate it by using silver-free films. Some silver- less products are vesicular, diazo and eletrostatic films. Photopolymer films contain carbon black as a substitute for silver. • Recover silver from fixing baths and have a com- mercial recycler pick it up. Purchase a silver recov- ery unit and perform the recycling of fixer on premises. • Add ammonium thiosulfate to silver contaminated baths to extend the allowable buildup of silver. Process Baths • Use an acid stop bath prior to the fixing bath. This reduces the effect of an alkaline developer on the 3
