为布朗中心的居民提供新的饮用水源 威斯康星州曼尼托沃克县（CBCWA）公共事业部（MPU）开发了一个项目，用于设计和安装 新建一座25 mgd的浸没式微滤（MF）装置，从 密歇根湖。WTP的工作是MPU之间的一个联合项目的一个组成部分 以及CBCWA，以经济高效的方式将密歇根湖的水引入该地区。新的 MF设施将安装在MPU退役的常规处理设施内 自2000年一座12 mgd压力MF装置启动后，该装置已离线。新的 浸没式MF设施包括最终45 mgd容量的膜空间 配备预处理过滤器和化学清洗设备的设备均为封闭式 在10 mgd常规过滤器廊道的空间内。这些设施还包括 swing cell，可作为二次回收撬间歇性运行，减少 在必须清除残余物的期间，残余物的排放量小于工厂流量的1% 排入下水道。与联合项目相关的其他改进包括 新建4000英尺高的湖泊取水口，28 MGD原水泵站，3 MG成品水 水库，25 MGD成品水泵站，60多英里的输水干管， 以及十几个计量和减压站。 本文对压力传感器的设计进行了有趣的比较 工厂和新的浸没式MF工厂。新的浸没式膜系统已投入使用 施工的最后阶段以及启动和测试的初始阶段。 包括数字。

In order to provide a new source of drinking water to residents of Central Brown County (CBCWA), Wisconsin, the Manitowoc Public Utilities (MPU) developed a project to design and construct a new 25 mgd submerged microfiltration (MF) plant that would draw water from Lake Michigan. The work at the WTP is one component of a joint project between MPU and the CBCWA to cost effectively bring Lake Michigan water to the region. The new MF facilities will be installed within MPU's decommissioned conventional treatment plant, offline since 2000 after the startup of a 12 mgd pressure MF plant. The new submerged MF facility includes space for an ultimate 45 mgd capacity of membrane equipment with pretreatment strainers and chemical cleaning equipment all housed within the space of a 10 mgd conventional filter gallery. The facilities also include a swing cell, which can operate intermittently as a secondary recovery skid, reducing residuals waste to less than 1% of plant flow during periods in which residuals must be discharged to the sewer. Other improvements associated with the joint project include a new 4,000 foot lake intake, 28 MGD raw water pumping station, 3 MG finished water reservoir, 25 MGD finished water pumping station, over 60 miles of transmission main, and over a dozen metering and pressure reducing stations. This paper provides interesting comparisons between the design of the pressure MF plant and the new submerged MF plant. The new submerged membrane system is in the final stages of construction and in the initial stages of startup and testing. Includes figures.
