Since the development of brackish water reverse osmosis (RO) membranes their use hasseen rapid development. All major RO membrane manufacturers have developed one ormore brackish water RO membranes. In the last ten years these membranes have seen alarge decrease in price and an increase in productivity making brackish groundwaterdesalination an attractive option in water scarce regions. The latest generation ofbrackish water RO membranes has shown marked improvements in terms of operatingpressure and this could translate into lower costs for brackish water treatment. This paperpresents the results of pilot testing conducted on these new generation low pressurebrackish water RO membranes for groundwater desalination. Two new membranes weretested - ESPA 4 manufactured by Hydranautics, Inc, Oceanside, CA and 4040 BLmanufactured by Saehan Industries, South Korea. Hydranautics, Inc. is a wellestablished membrane manufacturer in the US while Saehan Industries does not currentlyhave a presence in the US market. An older generation membrane (ESPA 2 fromHydranautics) was also operated in parallel with the new generation membranes toprovide baseline data for comparison. This project was conducted as a part of a researchprogram initiated by Desalination Research and Innovation Partnership, which consists ofwater purveyors in the Southern California region. Includes tables, figures.
