Brominated Resins   Water Quality Products July 2003   Ken Korslin, CWS-III, Pentair Water Treatment, Plymouth Products Division
In 1957 The Dow Chemical Corp. addressed the negatives of using bromine by creating a brominated ion exchange resin, which opened up the use of bromine in offshore water treatment applications.2 Today, polybromide resin is used in many offshore water treatment systems. The fact that bromine can be added to water that previously has been chlorinated makes polybromide resin a practical solution to accommodate the multiple sources of water in offshore applications.

Project Compares Brackish Water Desalination Technologies - Part 1   Water Engineering & Management February 2002   Jim Passanisi, Janet Persechino and Todd K. Reynolds
In Port Hueneme, California, a state-of-the-art desalination facility uses three brackish water desalination technologies: reverse osmosis (RO), nanofiltration (NF) and electrodialysis reversal (EDR), operated side-by-side to produce over three million gallons per day (mgd) of high quality drinking water. The Brackish Water Reclamation Demonstration Facility (BWRDF) is the cornerstone of the Port Hueneme Water Agency’s (PHWA) Water Quality Improvement Program. In addition to providing desalted water for local use, the BWRDF also serves as a full-scale research and demonstration facility.
