Engineering and Economic Study of Reverse Osmosis Brackish Water Desalting Plants. Design of 3-25MGD Low Pressure Plants.

摘要

An engineering and economic analysis (based on 1972prices and technology) of low pressure reverse osmosis brackish water desalting plants employing hollow fine fibers at 100and 150psi,and spiral wound modules at 200and 250psi was undertaken. Three moderate salinity brackish waters were studied;one at the lowest pressure for each module design at 50% recovery,one with the lowest pressure at 60% recovery,and the third with the highest pressure at 60% recovery. Lower cost plastic components were utilized in the designs to the maximum extent possible. Capital and operating water costs were estimated at 3, 10and 25MGD capacity (a total of 18cases).
