Description:
This report documents the activities performed and the results obtained from the arsenic removal treatment technology demonstration project at Conneaut Lake Park (the Park) in Conneaut Lake, PA. The main objective of the project was to evaluate the effectiveness of AdEdge Technologies’ (AdEdge) coagulation/filtration (C/F) system, using GreensandPlus™ media (branded as AD-GS+ by AdEdge), in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 g/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 included system operation, water quality (both across the treatment train and in the distribution system), process residuals, and capital and O&M cost.
