Impact/Purpose:
The objective of the arsenic demonstration program is to conduct 40 full-scale arsenic treatment technology demonstration studies on the removal of arsenic from drinking water supplies. The specific objectives are to: 1. Evaluate the performance of the arsenic removal technologies for use on small systems; 2. Determine the required system operation and maintenance (O&M) and operator skill levels; 3) Characterize process residuals produced by the technologies; 4) Determine the capital and O&M cost of the technologies. This report summarizes the performance of STS's system at the Oak manor MUD in Alvin, TX during the first six months from April 25 through October 25, 2006. The types of data collected included system operation, water quality (both across the treatment train and in the distribution system), residuals, and capital and preliminary O&M cost.
Description:
This report documents the activities performed and the results obtained from the first six months of the EPA arsenic removal technology demonstration project at the Oak Manor Municipal Utility District (MUD) facility at Alvin, TX. The main objective of the project is to evaluate the effectiveness of the Severn Trent Services (STS) Arsenic Package Unit (APU)-30S in removing arsenic to meet the maximum contaminant level (MCL) of 10 µg/L. Additionally, this project evaluates 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 costs.
