Calgon Carbon Corp. received a $7.5 million contract from the Water Quality Authority for the City of Monterey Park, Calif., for the turnkey design and installation of a state-of-the-art drinking water treatment system for the removal of perchlorate. The system will use Calgon’s modular ion exchange technology and will treat up to 5,000 gpm.
The system was activated earlier this summer, according to the San Gabriel Basin Water Quality Authority. The plant will stop the perchlorate plume from progressing. Additional plants for removing perchlorate are scheduled to start-up by the end of the year, which will bring the overall treatment to more than 50 million gallons of drinking water each day.
