Arsenic Removal from Drinking Water by Adsorptive Media. U.S. EPA Demonstration Project at Taos, NM. Final Performance Evaluation Report

摘要

This report documents the activities performed and the results obtained for the EPA arsenic removal technology demonstration project at the Town of Taos in New Mexico. The main objective of the project was to evaluate the effectiveness of Severn Trent Services (STS) SORB 33 adsorptive media in removing arsenic to meet the maximum contaminant level (MCL) of 10 .g/L. Additionally, this project evaluated (1) the reliability of the treatment system for use at small water facilities, (2) the required system operation and maintenance (O&M) and operator skill levels, and (3) the capital and O&M cost of the technology. The project also characterizes water in the distribution system and residuals generated by the treatment process. The types of data collected include system operation, water quality, process residuals, and capital and O&M cost.
