Electrodialysis Reversal began in the 1970s as an improvement on the Electrodialysis technology with a cell pair composed of an anion membrane, a diluting spacer, a cation membrane, and a concentrating spacer. Building on the improvement of an old technology through continuous research and development efforts, current industry trends and leading edge innovations in new membrane material, stack design, and electrode construction has kept this technology viable for both brackish water desalination and concentrate management applications. Many of the special characteristics of this technology provide benefits for certain applications where NF/RO membranes are less suitable, especially for high TSS and silica water or water with high organic and biological fouling propensity.
