Ionics, Incorporated has received a $5.6 million order from the Foss Reservoir Master Conservancy District in Western Oklahoma.
Under the recently-awarded contract, Foss will replace its existing electrodialysis (ED) membrane-based system with the newest version electrodialysis reversal (EDR) system, the Ionics EDR 2020® system. The EDR 2020 will convert the Reservoir's high salinity, high calcium sulfate brackish surface water into fresh drinking water. Replacing the existing ED system with the new EDR system will also allow Foss Reservoir to increase its water production from 3 million gallons per day to 4.5 million gallons per day to meet the area's increasing potable water needs.
In addition, the new EDR's system will allow the Foss Reservoir Master Conservancy District to reduce operating and maintenance costs as well as easily integrate with the reservoir's existing pretreatment system.
In the early 1970s, Foss Reservoir chose Ionics to build what was then the largest water desalination plant in the United States. Since then, the Foss Reservoir desalination plant has been producing fresh drinking water from brackish water sources on a daily basis for up to 15,000 people in the surrounding communities of Clinton, Cordell, Hobart and Bessie, Oklahoma.
