Abstract
A desalination system comprises a silica removal unit. The silica removal unit comprises first and second electrodes, a plurality of ion exchange membranes disposed between the first and second electrodes and a plurality of spacers disposed between adjacent ion exchange membranes and between the first and second electrodes and the respective ion exchange membranes. The plurality of the ion exchange membranes comprises a pair of cation exchange membranes and a pair of anion exchange membranes disposed between the pair of cation exchange membranes. A first channel is defined between the anion exchange membranes and second and third channels are defined between each anion exchange membrane and an adjacent cation exchange membrane. A silica removal apparatus and a desalination method are also presented.
