This slide presentation outlines bench and pilot testing of high capacity, single-pass ion exchange resins for perchlorate removal. Testing objectives included: independent testing of existing and new-to-market ion exchange resins to determine and compare perchlorate removal performance; communicate with resin manufacturers to obtain their recommendations on resins, suitable testing conditions, and full-scale operations; and, evaluate additional factors in the use of new high-capacity ion exchange resins, including potential for nitrosamine release from resins and concentration of co-contaminants on high-capacity resins (e.g., uranium). Bench-scale isotherms approach and results are given, along with mini-column evaluation approach and results and pilot-scale column approach and results. Background for Nitrosamine testing is outlined, along with California DHS Notification Levels, nitrosamine leaching and implications, and residuals management. Includes tables, figures.
