Study of Electrical Analogue for Electrodialysis
Office of Saline Water Research and Development Progress Report No. 238 (February 1967), prepared by the Astropower Laboratory of Douglas Aircraft Company. Develops a mathematical electrical-network analogue model of the electrodialysis desalination process, decomposing each stage into resistive sub-elements (concentration polarization, ohmic polarization, membrane resistance, electrode polarization, and parasitic duct losses). Applies the model to operating plants at Webster, South Dakota and Buckeye, Arizona, achieving agreement within 94% of measured stack resistance, and projects 15-45% resistance reductions through improved hydrodynamics and advanced membranes.
