Design studies were performed for a 6.0 MGD seawater reverse osmosis (SWRO) plant to be located at the San Diego Gas and Electric generating station at South Bay, San Diego, California. The studies presented herein are concerned with optimization of the desalination process for the seawater conditions and economic factors prevailing at the site. The plant under consideration utilizes a single stage reverse osmosis process with seawater feed supplied from either beach wells or the power plant cooling water outlet. Composite membranes of polyamide material in a spiral wound configuration as manufactured by Fluid Systems have been assumed as the basis for performance projections. Significant seasonal variation of seawater temperature occurs at this site, requiring that year-around performance be considered in the design. The sensitivity of consumable and capital costs to conversion rate was explored and a rate of 50 percent chosen. Several strategies for capital and operation cost reduction were evaluated, including the use of the power plant's cooling water outlet as the supply to the seawater reverse osmosis (SWRO) process. Use of the power plant cooling water outlet as the supply was found not to be beneficial, due to capital costs.
