斯科茨代尔市的查帕拉尔水处理厂最近开始运行 采用创新的综合工艺处理咸河项目水，包括 混凝除砷，浸没式超滤直接过滤 膜和颗粒活性炭（GAC）接触器，用于去除总有机碳（TOC）和引起味道和气味的物质 化合物。辅助工艺包括用于洗涤水回收的平板沉降器和 用于去除固体的离心机。这座30 mgd新设施的独特工艺是 经过六个月的试验规模运营，经过竞争性评估 四种膜系统以及臭氧和两种不同类型的GAC。膜 由于场地很小，水质变化很大，因此优先采用这种工艺 送到工厂。整个设施，包括5.5毫克的地下水库，坐落在 占地仅11英亩，旨在最大限度地减少对社区的影响。 这些设施的设计和建设面临重大挑战。此外 对于一个非常小、形状不规则的场地，需要解决相邻邻居的问题 需要维护驼背山的景观，公园设施 需要升级，需要消除浊度和砷的显著变化 需要减少系统中消毒副产物（DBP）的形成。显然，一个先进的 需要治疗系统来治疗多种挑战。

The City of Scottsdale's Chaparral Water Treatment Plant recently began operation treating Salt River Project water using an innovative integrated process consisting of coagulation for arsenic removal, direct filtration through submerged ultrafiltration membranes, and granular activated carbon (GAC) contactors for removal of total organic carbon (TOC) and taste and odor causing compounds. Ancillary processes include plate settlers for wash water recovery and centrifuges for solids removal. The unique process for this new 30 mgd facility was developed through six months of pilot-scale operations which competitively evaluated four membrane systems as well as ozone and two different types of GAC. Membrane processes were preferred due to the very small site and the highly variable water quality delivered to the plant. The entire facility, including the 5.5 MG buried reservoir, sits on only 11 acres and is constructed to minimize neighborhood impact. Substantial challenges existed for the design and construction of the facilities. In addition to a very small, irregularly shaped site, the issues of adjacent neighbors needed to be addressed, views of Camelback Mountain needed to be maintained, the park facilities needed to be upgraded, significant variations in turbidity and arsenic needed to be controlled, and disinfection byproduct (DBP) formation needed to be reduced in the system. Clearly, an advanced treatment system to treat multiple challenges was required.
