位于佛罗里达州恩格尔伍德的恩格尔伍德水区（EWD）经营着一个微咸水区 水反渗透（RO）脱盐设施具有近25年的运行历史和 处理技术“第一”和工艺进步。大量的研究、改进和改进 多年来的扩建提高了反渗透性能，降低了能耗 消耗本文讨论的一些进展包括: 制定特定位置、特定膜通量标准； 创新的细菌污染研究和污染控制补救措施； 能量回收与膜级通量- 平衡方法； 使用三代螺旋缠绕反渗透膜元件；和 创新的滚装列车设计特点，最大限度地提高性能，最大限度地降低成本 随着给水盐度从最初的4700 mg/L TDS增加到当前值 在一些约8000 mg/L的井中可以看到。 本文总结了EWD反渗透装置的历史，并描述了该工艺 其中一些进步不仅对Englewood设施产生了影响，而且对 一般来说，膜行业。包括5个参考文献、表格和图表。

The Englewood Water District (EWD) located in Englewood, Florida operates a brackish water reverse osmosis (RO) desalting facility with nearly 25 years of operating history and treatment technology "firsts" and process advances. Numerous studies, improvements, and expansions over the years have improved RO performance and reduced energy consumption. Some of the advances that are discussed in this paper include: development of site-specific, membrane-specific flux criteria; innovative bacterial fouling study and fouling control remedial measure; energy recovery and membrane stage flux-balancing methods; use of three generations of spiral wound RO membrane elements; and, innovative RO train design features to maximize performance and minimize costs with increasing feed water salinity from an initial 4,700 mg/L TDS to current values seen in some wells of approximately 8,000 mg/L. This paper summarizes the history of the EWD RO plant and describes the process advances, some of which have had an impact not only on the Englewood facility, but on the membrane industry in general. Includes 5 references, tables, figure.
