Arsenic Removal from Drinking Water by Iron Removal and Adsorptive Media U.S. EPA Demonstration Project at Stewart, MN, Final Performance Evaluation Report
Condit, W. E., A. S. Chen, L. Wang, AND A. Wang. Arsenic Removal from Drinking Water by Iron Removal and Adsorptive Media U.S. EPA Demonstration Project at Stewart, MN, Final Performance Evaluation Report . U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-09/144, 2010.
To inform the public
This report documents the activities performed and the results obtained from the one-year U.S. Environmental Protection Agency (EPA) arsenic removal technology demonstration project at the Stewart, MN facility. The main objective of the project was to evaluate the effectiveness of Siemens’ Type II AERALATER® system for iron removal and AdEdge Technologies’ Arsenic Package Unit (APU)-300 system for subsequent arsenic removal. The effectiveness was evaluated based on the system’s ability to remove arsenic to below the new arsenic maximum contaminant level (MCL) of 10 g/L. Further, this project also 1) evaluated the reliability of the treatment system for use at small water facilities, 2) determined the required system operation and maintenance (O&M) and operator skill levels, 3) characterized process residuals generated by the treatment process, and 4) determined the capital and O&M cost of the technology. The types of data collected include system operation, water quality (both across the treatment train and in the distribution system), process residuals, and capital and O&M cost.
