新泽西州新不伦瑞克市拥有并运营着一座地表水处理厂 容量为18mgd。该工厂的压力过滤器已安装 它们的使用寿命已经结束，需要一个新的过滤系统。2002年，这座城市开始建设 通过进行潜在风险的可行性研究，规划压力过滤器的更换 替换选项。研究发现，膜过滤是一种比传统过滤更好的选择 重力过滤系统的扩建。可行性研究完成后，膜厂的设计基础已确定 进行。膜系统的初始容量为12 MGD，并可扩展 到未来的24 MGD。设计的基础包括:桌面评估的几个方面 膜供应商；选择三家薄膜供应商进行为期三个月的试点研究； 根据初步研究结果对三个膜系统进行概念设计；和 为最终设计选择最佳膜系统。 使用Norit的X-flow膜、GE/Zenon的ZW进行了初步试验- 1000膜 以及Memcor的CMF-s膜。最终设计于5月完成 2006年。膜系统于2008年7月启动。本文讨论了项目设计和运营阶段的重要方面。 将要描述的设计的关键方面包括 三个膜系统，膜的选择和采购过程，反洗废水 处理系统，能够回收废过滤器反洗，以及CIP中和和 处理系统。在调试和运行方面，本文对试验结果进行了比较 从中试到全尺寸运行，膜的性能比较 使用现有重力过滤器，以及如何优化每个过滤系统的流量。包括3个参考文献、表格和图表。

The City of New Brunswick, New Jersey owns and operates a surface water treatment plant that has a capacity of 18 MGD. The plant's pressure filters have reached the end of their useful life and a new filtration system is needed. In 2002, the City began planning for the pressure filter replacement by performing a feasibility study of potential replacement options. The study found that membrane filtration was a much better option than expansion of the gravity filtration system. Upon completion of the feasibility study, a basis of design for the membrane plant was conducted. The initial capacity of the membrane system will be 12 MGD and will be expandable to 24 MGD in the future. The basis of design included: desktop evaluation of several membrane suppliers; selection of three membrane suppliers for a three month pilot study; conceptual design of the three membrane systems based on the results of the pilot study; and, selection of the optimum membrane system for final design. Pilot testing was performed using Norit's X-flow membrane, GE/Zenon's ZW-1000 membrane and Memcor's CMF-S Membrane. Final design was completed in May 2006. Startup of the membrane system was performed in July 2008. This paper discusses the significant aspects of the design and operational phases of the project. Key aspects of the design that will be described include a summary of the pilot testing of the three membrane systems, the membrane selection and procurement process, the backwash waste handling system which enables recycling of spent filter backwash, and CIP neutralization and disposal system. Regarding commissioning and operation, the paper compares the results of the pilot testing to the full scale operation, how the performance of the membranes compares with the existing gravity filters, and how the flowrate from each filtration system is optimized.
