Silver Recovery
Polymer filtration uses water-soluble polymers to selectively bind metal ions. The polymer-metal association is filtered and concentrated by commercially available ultrafiltration equipment. Silver can be reclaimed from electroplating and photofinishing waste water thereby reducing sludge formation and recovering valuable materials. The discharged water meets all regulatory requirements and can be recycled. Commercial applications have been successfully demonstrated.
In addition to photo processing, mentioned above, there are major market segments in the recovery of silver from x-ray film and printing process streams. By the year 2010, Polymer Filtration technology could reduce waste production by 100,000 tons. The resulting energy savings and waste minimization reduces the cost of business practices and increases profits.
- Engineering prototype has been developed and demonstrated for similar applications;
- Patents have been filed and issued.
