Abstract
Electrodialysis reversal (EDR) was pilot tested on moderate TDS, high silica groundwater with elevated levels of fluoride and arsenic at Fort Irwin, California. During 75 days of continuous testing, results demonstrated that with minimal pretreatment, EDR was capable of producing water that consistently met Fort Irwin's agreed upon water quality goals. The pilot unit was optimized to maximize feedwater recovery and stay within safe operating parameters relative to applied voltage and sparingly soluble salt supersaturation. A scale inhibitor and hydrochloric acid were added at low doses to the concentrate recycle loop to enhance recovery. This article presents the results of EDR pilot testing, which was performed to help design a full-scale facility for Fort Irwin's new 6-mgd (22,712 m 3 /d) water treatment plant.
