Adsorbents for Recovery of Metals from Wastewaters and Slurries

51005-98-I Adsorbents for Recovery of Metals from Wastewaters and Slurries--ReyTech Corporation, 63140 Britta Street, C-100, Bend, OR 97701-5716; (541) 330-2370 Dr. Thomas A. Reynolds, Principal Investigator Dr. Thomas A. Reynolds, Business Official DOE Grant No. DE-FG03-98ER82656 Amount: $75,000 Separation processes for recovery of heavy-metals from contaminated water and slurries are needed for industrial and mining operations, groundwater-cleanup of Super-Fund sites, and DOE facilities. Conventional adsorbent technologies have had limitations that preclude their widespread use in the treatment of metal-contaminated wastewater and slurries. Specifically, many adsorbent systems lack capacity, selectivity, robustness, and the ability to be regenerated. The objective of this project will develop a versatile family of regenerable adsorbents that have high capacity and selectivity for heavy-metals, are chemically robust, and can be used in high solid-content slurries. In Phase I, feasibility will be demonstrated by fabricating a series of these adsorbents, incorporating them into small-scale modules, and testing extensively for recovery of heavy-metals from contaminated water. Commercial Applications and Other Benefits as described by the awardee: Development of cost-effective and robust adsorbents for recovery of metals from contaminated water would have widespread application in chemical processing environmental cleanup._
