Metal Recovery and Water Reuse

Metal recovery can be achieved in two ways (1) recovered metal salts can be recirculated back into process baths, or (2) recovered elemental metal can be sold to a metals reclaimer or reused in the plating process. Some of the technologies that are being successfully used to recover metals and metal salts include  

While these treatment technologies are typically used to recover chemicals from rinsewater effluent, they can also be employed for spent process baths. The wastewater that is produced after the metal recovery is often pure enough to be reused for rinsing. 

Various methods for recovering process chemicals and rinsewater from rinsewater effluent are described below
