摘要

The Kansas City, Kansas, Board of Public Utilities (BPU), a large surface water supplier serving a population of nearly 150,000, is an active participant in the federally-mandated Information Collection Rule (ICR). The water processing facility located on the Quindaro Bend of the Missouri River is a conventional clarification plant with an average day demand of 28 MGD and maximum day demand of 40 MGD. The seasonal total organic carbon (TOC) levels of the Missouri River water range from 1.8 mg/L to 12.1 mg/L with an average value of 4.0 mg/L. BPU has conducted various bench, pilot and full-scale test to optimize the treatment process and to comply with the drinking water regulations. The year-long nanofiltration membrane study is another example of BPU's proactive investment in the emerging technologies. After careful thought and deliberation, BPU decided to fulfill the requirements of the ICR by conducting a single element bench-scale test (SEBST) using a single membrane element in a continuous flow mode. The rationale for conducting a single element study is that the utility felt a single element study would produce more consistent data for future design purposes. This paper addresses both the design and operational aspects of the SEBST program at BPU and discusses its implication for future plant process modifications. Includes table. 堪萨斯州堪萨斯城公共事业委员会（BPU）是一家大型地表水供应商，服务人口近15万，是联邦政府授权的信息收集规则（ICR）的积极参与者。位于密苏里河昆达罗河湾的水处理设施是一个传统的澄清厂，平均日需求量为28 MGD，最大日需求量为40 MGD。密苏里河水的季节性总有机碳（TOC）水平在1.8 mg/L到12.1 mg/L之间，平均值为4.0 mg/L。BPU进行了各种台架、中试和全尺寸试验，以优化处理过程，并遵守饮用水法规。为期一年的纳滤膜研究是BPU积极投资新兴技术的另一个例子。经过深思熟虑，BPU决定通过进行单元素测试来满足ICR的要求-在连续流动模式下使用单个膜元件进行的规模试验（SEBST）。进行单元素研究的理由是，公用事业公司认为单元素研究将产生更一致的数据，用于未来的设计目的。本文论述了BPU SEBST项目的设计和运行方面，并讨论了其对未来工厂工艺改造的影响。包括桌子。展开▼
