| 摘要： | This project was undertaken to better understand the technical and cost implications of the use of membrane filtration as pretreatment for seawater reverse osmosis (RO). The pilot study was conducted using raw feedwater from the Corpus Christi Bay in Texas, at the San Patricio Municipal Water District facility. The pilot study consisted of a side-by-side comparison of membrane filtration and conventional filtration, both followed by separate RO pilot systems, testing over an approximate 1-year period. The results indicate that membrane filtration produced far superior water quality for pretreatment, measured by reduced turbidity and by the silt density index (SDI). The resulting impact on the RO performance was a significantly lower RO cleaning frequency. The economic evaluation indicates that on a life-cycle cost analysis, the total water cost (TWC) for a plant using membrane filtration is 4-8% less than a plant using media filtration. / NOTE: Final rept. for 27 Sep 01-26 Dec 04. / Supplementary Notes: Prepared in cooperation with Texas Transportation Inst., College Station.
