Abstract |
This report documents the activities performed and the results obtained from January 30, 2006 to April 29, 2007 at the U.S. Environmental Protection Agency (EPA) Arsenic Removal Technology Demonstration site in Sabin, MN. The main objective of the project was to evaluate the effectiveness of Kinetico's FM-248-AS arsenic removal system using Macrolite (Trade Name) media in removing arsenic from raw drinking water to meet the arsenic maximum contaminant level (MCL) of 10 micro g/L. Additionally, this project evaluated: (1) the reliability of the treatment system for use at a small water facility; (2) the required system operation and maintenance (O&M) and operator skill levels; and (3) the cost-effectiveness of the technology. The project also characterized water in the distribution system and residuals generated by the treatment process. The types of data collected included system operational data, water quality data (both across the treatment train and in the distribution system), process residual data, and capital and O&M cost data. |
