亚利桑那州斯科茨代尔的水校园项目是一个水资源管理设施，应用前沿技术帮助确保该沙漠社区未来的供水。作为该项目的一部分，将使用一个集成膜系统（IMS）（由微滤（MF）和反渗透（RO）组成），在次表面充电之前处理地表水和三级出水。补给的水将通过土壤渗透，最终与当地地下水混合。该市从亚利桑那州水资源部（ADWR）处获得基于补给量的信贷，用于在其服务区域内提取地下水。 微滤系统处理地表水和废水。有时，两种膜都在相邻单元中同时处理，为比较不同进料源的膜性能提供了独特的机会。反渗透系统设计用于处理三级废水，因此，最初的运行计划要求在所有可用废水用于灌溉时关闭系统。然而，由于水质和运营方面的考虑，该计划被修改。目前，当Alleflunt用于灌溉时，一些科罗拉多河水（通过亚利桑那州中部项目（CAP）运河输送）现在通过RO进行处理。 该项目的膜部分于1999年秋季开始运行。2000年5月，购买了额外的微滤器以增加产量。管道改造计划增加系统灵活性，最大限度地利用微过滤器。本文将讨论与使用IMS进行三级出水回灌和后续间接饮用水回用相关的工艺操作、膜性能、生产成本和水质。包括8个参考文献、表格、图表。

Scottsdale, Arizona's Water Campus Project is a water resources managementfacility applying leading edge technology to help ensure future water supplies inthis desert community. As part of the project, an integrated membrane system(IMS), (consisting of microfiltration (MF) and reverse osmosis (RO)), is beingused to treat both surface water and tertiary effluent prior to sub-surfacerecharge. The water that is recharged will percolate through the soil andeventually mix with local groundwater. The city receives credit, based on thevolume recharged, from the Arizona Department of Water Resources (ADWR) towardsgroundwater withdrawals within its service area. The microfiltration systemtreats both surface water and effluent. At times, both are treated simultaneouslyin adjacent units, affording a unique opportunity to compare membrane performanceon different feed sources. The RO system was designed to treat tertiary effluentand, as a result, the original operating plan required the system be shut downwhen all available effluent was used for irrigation. However, water quality andoperational concerns resulted in a modification to this plan. Currently, when alleffluent is being used for irrigation, some Colorado River water (delivered viathe Central Arizona Project (CAP) canal) is now treated through the RO. Themembrane portion of the project began operation in the fall of 1999. In May of2000, additional microfilters were purchased to increase production. Pipingmodifications are planned to increase system flexibility and maximize microfilteruse. This paper will discuss process operations, membrane performance, productioncosts, and water quality relevant to the use of an IMS for the recharge, andsubsequent indirect potable reuse of tertiary effluent.
