Integrated Ion Exchange Regeneration Process for Perchlorate in Drinking Water

摘要

This report describes an evaluation of an integrated ion exchange (IIX) regeneration process for perchlorate treatment in drinking water. IIX combines three separate processes: conventional ion exchange (IX) with perchlorate selective resin for wellhead treatment of perchlorate contaminated water, regeneration of resin using tetrachloroferrate (FeCl4-) anion and then returning the resin to service, and the destruction or disposal of perchlorate recovered from the resin. The demonstration site was at an operating municipal water treatment plant owned by Fontana Water Company (FWC), in Fontana, CA. ARCADIS was the prime contractor (contract no. W912HQ-06-C-004), with Calgon Carbon Corporation (Calgon) and Oak Ridge National Laboratory (ORNL) as partners. Funding and oversight were provided by the Environmental Security Technology Certification Program (ESTCP) and the Naval Facilities Engineering Command / Engineering Service Center (NAVFAC ESC). The project was funded under a special congressionally directed program to ESTCP for wellhead perchlorate treatment. This work was contracted through the Corps of Engineers in Alexandria, VA, and overseen by NAVFAC ESC. The program involved field activities at FWC and at a Calgon facility.
