德克萨斯州普夫卢格维尔市已修建设施，利用新的供水来满足其快速增长的人口日益增长的需求。在这个项目中，选择了一种直接混凝膜过滤的创新应用。本文提供了工艺流程图，并列出了处理厂的组件。2006年2月，完成的膜系统开始测试。工厂于2006年3月启动。该市一直在学习操作膜厂，因为他们之前没有经验（该市的供水以前是地下水）。该市还没有进行试验，以找到去除有机物的最佳混凝剂剂量。然而，自启动以来，有机物去除率在22%到57%之间，平均为36%。 这些去除水平接近膜试验期间发现的水平（41%以上）。滤液浊度非常好，范围为0.02至0.08 NTU。正如中试研究和全面运行所证明的那样，普夫卢格维尔市的新地表水处理厂不需要在膜系统之前10到30分钟的普遍接受的混凝剂接触时间。根据德克萨斯州环境质量委员会的规则和法规，混凝剂接触时间可以大大缩短，并且仍然满足所需的处理水质量目标。通过测试膜过滤与直接混凝的创新应用，普夫卢格维尔市能够满足其项目预算限制，并建造一座处理厂，以满足消费者的需求和监管压力，从而改善当前和未来的饮用水质量。 包括桌子。

The City of Pflugerville, Texas has built facilities to utilize a new water supply to meet the growing needs of its rapidly increasing population. For this project, an innovative application of membrane filtration with direct coagulation was chosen. The paper provides a process flow diagram and lists the treatment plant's components. The testing of the completed membrane system began in February 2006. The startup of the Plant began in March 2006. The City has been learning to operate the membrane plant since they had no prior experience (the City's supply was groundwater before). The City has not been experimenting to find the optimum coagulant dose for organic removal. However, the organic removals since startup range from 22% to 57% with an average of 36%. These removal levels are near those found during piloting of the membranes (41% plus). The filtrate turbidity is very good with a range of 0.02 to 0.08 NTU. As demonstrated by the pilot study and full-scale operation, the generally accepted coagulant contact time of 10 to 30 minutes prior to the membrane system is not needed for the City of Pflugerville's new surface water treatment plant. The coagulant contact time can be substantially reduced and still meet the required treated water quality goals in accordance with the Texas Commission on Environmental Quality Rules and Regulations. By testing an innovative application of membrane filtration with direct coagulation, the city of Pflugerville was able to meet its project budgetary constraints, as well as construct a treatment plant that will meet the consumer demand and regulatory pressure for better drinking water quality today and in the future.
