在佛罗里达州弗拉格勒海滩（Flagler Beach，Florida）的一个为期一年的项目中，对三卤甲烷（THM）控制和膜法生产饮用水的成本和有效性进行了调查，该项目的给水为高有机地下水。研究结果表明，膜系统可以在很长一段时间内控制三卤甲烷的形成，产生的成品水超过了质量和数量要求。弗拉格勒海滩膜厂的建设和运营成本与传统软化厂大致相同- -但成品水的质量会更高。据观察，与软化装置相比，膜装置的劳动强度更低，操作更容易。包括20个参考文献、表格和图表。

The cost and effectiveness of trihalomethane (THM) control and potable water production by a membrane process were investigated during a one-year project at Flagler Beach, Florida, where the feedwater was a highly organic groundwater. Results of the study showed that the membrane system could control the formation of THMs for an extended period, producing a finished water that exceeded quality and quantity requirements. Construction and operating costs for a membrane plant at Flagler Beach would be about the same as for a conventional softening plant--but the finished water would be of a superior quality. The membrane plant was observed to be less labor intensive and easier to operate than a softening plant. Includes 20 references, tables, figures.
