Arsenic Removal from Drinking Water by Coagulation/Filtration U.S. EPA Demonstration Project at Village of Waynesville, IL. Final Performance Evaluation Report

摘要

This report documents the activities performed and the results obtained from the arsenic removal drinking water treatment technology demonstration project at the Village of Waynesville, IL. The main objective of the project was to evaluate the effectiveness of the Peerless coagulation/filtration (C/F) system, using GreensandPlus (Trademark) filtration media with an anthracite cap, in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 microgram/L. Additionally, this project evaluated (1) the reliability of the treatment system, (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 characterized the water in the distribution system and process residuals produced by the treatment process. The types of data collected during the demonstration period included system operation, water quality (both across the treatment train and in the distribution system), process residuals, and capital and O&M cost.
