本幻灯片演示概述了一个关于实施浸没式膜技术以应对过滤挑战的项目。经过两年的MPA测试，Stillaguamish Ranney收集器源收到MPA 得分>20分。 根据华盛顿州卫生部（DOH）的说法，目前该病毒的来源是高风险的 受到直接地表影响（地下水受到 地表水）。它需要符合地表水处理规则（SWTR）。 概述的主题包括:SWTR合规挑战；Stillaguamish合规方法， 第一个主要因素:康复 兰尼收藏家； 第二个主要元素:安装过滤装置；膜中试研究；设备采购；项目现场；允许挑战；建筑设计挑战；其他设施设计挑战；clearwell溢流气隙设计；分销系统挑战；景观美化和雨水挑战；设计亮点；此外，还有建筑挑战。

This slide presentation outlines a project on implementing submerged membrane technology to meet filtration challenges. Following 2 years of MPA tests, the Stillaguamish Ranney Collector source received MPA score > 20. Per the Washington State Department of Health (DOH), source is now HIGH RISK of being under direct surface influence (groundwater under the influence of surface water). It needed to be brought into compliance with the Surface Water Treatment Rule (SWTR). Topics outlined include: SWTR compliance challenge; Stillaguamish compliance approach, first major element: rehabilitation of Ranney Collector; second major element: install filtration; membrane pilot study; equipment procurement; project site; permitting challenges; building design challenges; other facilities design challenges; clearwell overflow air gap design; distribution system challenges; landscaping and storm water challenges; design highlights; and, construction challenges.
