Materials Separation Team
Welcome to the Materials Separation Team Web Site which focuses on Polymer filtration, a membrane-based technology for metal-ion recovery. This exciting new separations technology uses specially designed, water-soluble chelating polymers that selectively bind metal ions to prevent metals from entering waste water streams and to prevent sludge formation. Thus the chelating 
groups are designed to selectively bind electroplating metals and reject metals such as sodium and calcium. Once the metal ions are bound to the soluble polymer - which range in molecular weight from 10,000 to 500,000 - they are filtered by membranes that do not allow the polymer-bound metals to pass through their pores. This process allows for both the removal and concentration of the metals from the rinse waters. The animation below shows graphically how the Polymer Filtration System works.
