Brackish water desalination is an important alternative for developing drinking water sources in water-scarce arid regions. Both electrodialysis reversal (EDR) and reverse osmosis (RO) are suitable technologies for desalination of brackish groundwater. The RO pilot testing, conducted with the groundwater from San Pasqual water basin (San Diego, California), containing 1300 mg/L of TDS and 60 mg/L of silica, demonstrated that the RO process could be operated at 10 gfd with 75% recovery and 96% total dissolved solids (TDS) rejection with an estimated cleaning frequency of 2 months. The performance of the EDR process, predicted from the modeling using WATSYS software for the same water chemistry, indicated that this process could be operated at 88% recovery with the TDS rejection of 78%. The order of magnitude cost estimates (-30% and +50%) were prepared for three different feed flow scenarios (3, 5, 8 MGD) for RO and EDR treating the same groundwater suggested that both processes were cost comparable. However, the costs associated with the concentrate disposal were not considered in this cost estimation. Includes 9 references, tables, figures.
