O.B.密西西比州杰克逊市柯蒂斯水处理厂（OBCWTP）是一座常规的每天2500万加仑（mgd）的工厂，由快速混合、絮凝、沉淀和过滤组成。该市希望将OBCWTP扩建至75MGD，最终扩建至100MGD。该市及其顾问对几种不同的处理工艺进行了初步测试，以评估处理技术在扩建工厂方面的效果，以及是否符合已颁布和拟议的法规。这些过程包括:浸没式和压力式膜；高速沉降；臭氧消毒；二氧化氯消毒；紫外线消毒。本文将特别关注由杰克逊市（City of Jackson）进行的膜先导试验。 该市与三家薄膜制造商签订合同，在theOBCWTP进行中试试验:Zenon；USF/Memco；还有IDI/Aquasource。包括表格、数字。

The City of Jackson, Mississippi, O.B. Curtis Water Treatment Plant (OBCWTP) is a conventional 25-million gallons perday (mgd) plant consisting of rapid mixing, flocculation, sedimentation andfiltration. The City wishes to expand the OBCWTP to a 75-mgd, and eventually100-mgd, plant. Pilot testing of several different treatment processes wasperformed by the City and their consultants to evaluate the treatmenttechnologies in terms of expanding the plant and meeting both promulgated andproposed regulations. These processes included: submerged and pressure membranes;high-rate sedimentation; ozone disinfection; chlorine dioxide disinfection; and,ultraviolet disinfection. This paper will concentrate specifically on themembrane pilot testing performed by the City of Jackson (City). The Citycontracted with three membrane manufacturers to perform pilot tests at theOBCWTP: Zenon; USF/Memco; and, IDI/Aquasource. Includes tables, figures.
