The potential impact of recent developments in both reverse osmosis and electro-dialysis membrane desalting technology is summarized. Particular emphasis is given to the status of advanced technology reverse osmosis membranes with chlorine resistance having single pass seawater desalination capability. Membranes capable of using low operating pressures for brackish water desalting are also reviewed. Results obtained with large prototype reverse osmosis modules and their potential effect on lowering plant capital costs are presented. Possible elimination of acid and use of ultrafiltration as the predominant pretreatment step in seawater desalination plants are also described. Recent developments in the high temperature electrodialysis program for seawater desalting and in the use of newly developed anion membranes for brackish water desalination are reviewed. Potential impacts on future membrane desalination R and D activity are discussed.
