本幻灯片概述了马尼托沃克（威斯康星州）公用事业公司（MPU）关于两个大型膜处理厂设计的案例研究。演讲大纲包括:背景和历史； MPU现有的膜设备； 新膜设备；和 对过去设施的改进。结论表明: 马尼托沃克新建的25 mgd浸入式MF工厂将 提供新项目的现有和预计用水需求 成立了中央布朗县水务局； 现有的微滤（MF）设施在1999年达到最先进水平，打破了 成本和进度方面的新进展； 在过去7年中，行业的快速变化 允许在成本、空间上进行大幅改进 要求，以及新设施的可操作性；和 随着该行业的不断发展，它提供了新的 公用事业公司考虑使用 膜技术。

This slide presentation outlines a case study at the Manitowoc (Wisconsin) Public Utilities (MPU) concerning the design of two large-scale membrane treatment plants. The presentation outline includes: Background and History; Existing Membrane Facility at MPU; New Membrane Facility; and, Improvements Over Past Facilities. Conclusions indicate that: new 25 mgd submerged MF plant in Manitowoc will provide existing and projected water needs for newly formed Central Brown County Water Authority; existing microfiltration (MF) facility state-of-the-art in 1999, breaking new ground in terms of cost and schedule; rapid changes in industry over last 7 years have allowed for drastic improvements in cost, space requirements, and operability at new facility; and, as the industry continues to develop it provides new opportunities for utilities considering the use of membrane technologies.
