✦ Synopsis

The cktrosorption process for desalinizing saline uatcr was conceiwd in 1963. It is a cyclic process in uhich ions in the feed water arc first sorbed into special three-layer membranes under the influence of a driving voltage and thus are removed from water and then dLorbed from the membranes to regenerate them. R&arch on the process has been sponsored continuously since 1%3 by the OtTice of Saline Water of the United States Dcpartmcnt of the Interior. Methods of preparing acceptabk three-hyrr~metnbrattes from available ion-selective membranes and non-&t&e tnataials have been developed. Ekctrosorption desalination experiments have shown (hat high coulomb efikiencies can be obtained. high degrees of desalination can beobtained. and dcsorption requires no more than X5:/, of the total time. hforcovcr, the results of short-term experiments strong!y suggest that feeds containing CaSOa or C&HCOJ)Z can be desalinized with no apparent cell blockage or damage to the membranes from precipitates.
