The objectives of this project was to establish the feasibility of High Temperature Electrodialysis (HTED) in a seawater desalting reference plant. The goal was to increase the energy efficiency and economics of seawater desalting over conventional electrodialysis by operating at temperatures ranging up to 140 F, using improved membranes, and incorporating innovations in the membrane stack and process design. A 30000 GPD reference plant (expandable to 50000 GPD) was designed, built and installed at the Wrightsville Beach Test Facility. Field testing was halted by the shutdown of the facility at the end of March, 1983, however, the abbreviated field test demonstrated the efficacy of most of the novel features, and an energy consumption of 40 KWH/Kgal was projected at 4 GFD, 130 F, and 50 % water recovery.
