密西西比州杰克逊市目前运营着两座水处理厂，J.H.费维尔水处理厂（WTP）最初建于1914年，O.B.柯蒂斯水处理厂（OBCWTP）于1993年开始运营。J.H.Fewell水处理厂和OBCWTP的原水来源分别为珠江和Ross Barnett水库。从1982年到1996年，这两个设施的平均需水量为每天3160万加仑（mgd）。人口预测显示，2011年的平均需求量为363万桶/日。然而，为了满足2012年的峰值需求和消防流量要求，将需要75 mgd的总最大流量。 1997年的总体规划得出结论，杰克逊市目前运营的水处理设施无法满足未来的需求和新提议的饮用水质量法规的要求。根据这一评估，需要扩建现有设施。对J.H.Fewell水处理厂和OBCWTP扩建方案的评估得出结论，J.H.Fewell电厂正接近其使用寿命，并在继续恶化。因此，通过停运J.H.Fewell水处理厂，并将OBCWTP扩建50 mgd，可实现额外的水处理能力。 1998年6月16日，密西西比州环境质量部（MDEQ）向杰克逊市发布了一项行政命令，以消除J.H.Fewell水处理厂明矾污泥和其他废物的排放。消除这种排放需要在J.H.Fewell水处理厂安装固体处理设施。由于这座不断恶化的设施需要大量资本支出，因此决定启动该设施的退役和OBCWTP的扩建，以满足行政命令。与MDEQ协商了一份合规时间表，包括将OBCWTPP扩建至75 mgd，并在2006年1月1日前消除Fewell水处理厂的明矾污泥排放。 为了达到水质目标，该市试点测试了几种不同的处理工艺，包括:膜处理；高速沉降；臭氧消毒；二氧化氯消毒，紫外线消毒。包括2个参考文献、表格和图表。

The City of Jackson, Mississippi, currently operates two water treatment plants, the J. H. Fewell water treatment plant (WTP), originally built in 1914, and the O.B. Curtis WTP (OBCWTP), which began operation in 1993. The J.H. Fewell WTP and the OBCWTP sources of raw water are the Pearl River and Ross Barnett Reservoir, respectively. Average water demand for both these facilities was 31.6 million gallons per day (mgd) from 1982 through 1996. Population projections indicate anaverage demand of 36.3 mgd will be required in 2011. However, to satisfy peak demand and fire flow requirements through 2012 a total maximum flow capacity of 75 mgd will be required. A 1997 Master Plan concluded that the current watertreatment facilities operated by the City of Jackson could not meet future demands and the requirements of newly proposed drinking water quality regulations. Based on this assessment, expansion of the existing facilities would be required. An evaluation of expansion options for both the J.H. Fewell WTP and the OBCWTP concluded that the J.H. Fewell plant was nearing its useful life and was continuing to deteriorate. Thus, additional water treatment capacity would be achieved by decommissioning the J.H. Fewell WTP and expanding the OBCWTP by 50 mgd. On June 16, 1998, the City of Jackson was issued an administrative order by the Mississippi Department of Environmental Quality (MDEQ) to eliminate the dischargeof alum sludge and other waste products from the J.H. Fewell WTP. The elimination of this discharge would require the installation of solids handling facilities at the J.H. Fewell WTP. Due to the large capital expenditure required for thisdeteriorating facility, it was determined the decommissioning of this facility and expansion of the OBCWTP be initiated to satisfy the administrative order. A compliance schedule was negotiated with MDEQ to include expansion of the OBCWTPto 75 mgd and the elimination of the alum sludge discharge from the Fewell WTP by January 1, 2006. In order to meet its water quality goals, the City pilot tested several different treatment processes including: membrane treatment; high-ratesedimentation; ozone disinfection; chloride dioxide disinfection, and, ultraviolet disinfection.
