将前体去除经济地整合到现有的小型微滤（MF）系统中 有几个挑战。通常，预算是有限的，必须与 现有的处理工艺。本文给出了一个案例研究，说明了可供选择的方法 小型MF系统中消毒副产物（DBP）前体的去除及工程问题 成功整合必须面对这一点。工程设计和运行结果如下: 用于科罗拉多州一个小型MF系统，该系统最近解决了一个高DBP问题。大麋鹿 Meadows是一个社区供水系统，使用50 gpm的加压MF系统处理水 溶解有机碳（DOC）在9至13 mg/L之间。分配系统总三卤甲烷（TTHMs）和卤乙酸 （HAA5）测试了250微克/升以上。 在考虑了几种选择之后，磁离子交换 （MIEX®）作为MF系统的预处理安装。MIEX®安装后， TTHMs和HAA5降至第2阶段消毒副产物规则（DBPR）限值以下。包括3个参考文献、表格和图表。

Integrating precursor removal economically into an existing small microfiltration (MF) system has several challenges. Typically, budgets are limited, and integration must be made with existing treatment processes. A case study is presented illustrating the options available for disinfection byproduct (DBP) precursor removal in small MF systems and the engineering issues that must be faced for successful integration. Engineering design and operating results are presented for a small Colorado MF system that recently solved a high DBP problem. Big Elk Meadows, a Community Water System, uses a 50 gpm pressurized MF system to treat water with dissolved organic carbon (DOC) between 9 to 13 mg/L. Distribution system Total Trihalomethanes (TTHMs) and haloacetic acids (HAA5) had tested more than 250 ug/L. After considering several options, magnetic ion exchange (MIEX®) was installed as pretreatment to the MF system. Following MIEX® installation, TTHMs and HAA5 dropped to below Stage 2 Disinfection Byproducts Rule (DBPR) limits. Includes 3 references, tables, figures.
